Circumstances:
The captain and first officer were assigned a two-leg overnight on-demand cargo flight. The flight crew were accustomed to flying night cargo flights, had regularly flown together, and were experienced pilots. The first leg of the trip was uneventful and was flown by the captain; however, their trip was delayed 2 hours and 20 minutes at the intermediate stop due to a delay in the freight arriving. The flight subsequently departed with the first officer as the pilot flying. While enroute, about forty minutes from the destination, the flight crew asked the air traffic controller about the NOTAMs for the instrument landing system (ILS) instrument approach procedure at the destination. The controller informed the flight crew of two NOTAMs: the first pertained to the ILS glidepath being unserviceable and the second applied to the localizer being unserviceable. When the controller read the first NOTAM, he stated he did not know what “GP” meant, which was the abbreviation for the glideslope/glidepath on the approach. The controller also informed the flight crew that the localizer NOTAM was not in effect until later in the morning after their expected arrival, which was consistent with the published NOTAM. The flight crew subsequently requested the ILS approach and when the flight was about 15 miles from the final approach fix, the controller cleared the flight for the ILS or localizer approach, to which the captain read back that they were cleared for the ILS approach. As the flight neared the final approach fix, the captain reported that they had the airport in sight; he cancelled the instrument flight rules flight plan, and the flight continued flying towards the runway. The airplane crossed the final approach fix off course, high, and fast. The cockpit voice recorder (CVR) transcript revealed that the captain repeatedly instructed the first officer to correct for the approach path deviations. Furthermore, the majority of the approach was conducted with a flight-idle power setting and no standard altitude callouts were made during the final approach. Instead of performing a go-around and acknowledging the unstable approach conditions, the captain instructed the first officer to use the air brakes on final approach to reduce the altitude and airspeed. Shortly after this comment was made, the captain announced that they were low on the approach and a few seconds later the captain announced that trees were observed in their flight path. The CVR captured sounds consistent with power increasing; however, the audible stall warning tone was also heard. Subsequently, the airplane continued its descent and impacted terrain about .70 nautical mile from the runway. The airplane was destroyed by impact forces and both occupants were killed.
Probable cause:
The flight crew’s continuation of an unstable dark night visual approach and the captain’s instruction to use air brakes during the approach contrary to airplane operating limitations, which resulted in a descent below the glide path, and a collision with terrain. Contributing to the accident was the captain’s poor crew resource management and failure to take over pilot flying responsibilities after the first officer repeatedly demonstrated deficiencies in flying the airplane, and the operator’s lack of safety management system and flight data monitoring program to proactively identify procedural non-compliance and unstable approaches.

Circumstances:
Before the personal instrument flight rules flight began, the pilot obtained a preflight weather briefing that indicated that instrument meteorological conditions, convective activity, and moderate-to-severe icing conditions would be occurring along the route of flight. According to track data, while the pilot was navigating to avoid weather, the pilot was using the autopilot for maneuvering. After the pilot reported to air traffic control that the airplane would be turning direct to its destination, the performance analysis of track data showed that the airplane began a slight left turn with a bank angle of about 10°, which was consistent with the intended route of flight. However, the turn then reversed, and the airplane began banking to the right, reaching about 120° right wing down during the next 70 seconds and showing a slow oscillation in pitch attitude. Satellite imagery showed that the airplane was likely in instrument meteorological conditions when it began a rapid descent, and the airplane’s descent rate was about 7,000 feet per minute. Postaccident examination of the airplane and right engine (the left engine was not recovered) revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation. The dynamics of the airplane’s movements after the right turn began indicated that the airplane likely was not being actively controlled when it diverted from the intended flightpath. The circumstances of this accident were thus consistent with the pilot’s lack of timely recognition that the autopilot was disengaged. The available evidence for this accident precluded a determination of where the pilot’s attention was directed while navigating direct to the destination. However, the turbulence would have increased the pilot’s workload, and the restricted visibility conditions would have prevented the pilot’s use of outside cues to detect deviations in the airplane’s attitude. Also, the initial roll rates might not have been sufficient to provide reliable cues to the pilot of the developing bank, and the convective conditions would likely have made it difficult for the pilot to detect and recover from the fully developed unusual attitude.
Probable cause:
The pilot’s failure to maintain control of the airplane while maneuvering in instrument meteorological conditions, which placed the airplane in an unusual attitude from which the pilot could not recover. Contributing to the accident was the convective and turbulent weather.

Circumstances:
According the commercial pilot and a flight instructor rated check pilot, they were conducting their first long-duration, aerial observation flight in the multiengine airplane, which was recently acquired by the operator. They departed with full fuel tanks, competed the 5-hour aerial observation portion of the flight, and began to return to the destination airport. About 15 miles from the airport, the left engine fuel warning light illuminated. Within a few seconds, the right engine stopped producing power. They attempted to restart the engine and turned the airplane toward an alternate airport that was closer. The pilots then turned on the electric fuel pump, the right engine began surging, and soon after the left engine stopped producing power. They turned both electric fuel pumps to the low setting, both engines continued to surge, and the pilots continued toward the alternate airport. When they were about 3 miles from the airport, both engines lost total power, and they elected to land on a highway. When they were a few feet above the ground, power returned briefly to the left engine, which resulted in the airplane climbing and beginning to roll. The commercial pilot pulled the yoke aft to avoid a highway sign, which resulted in an aerodynamic stall, and subsequent impact with trees and terrain. The airplane sustained substantial damage to the wings and fuselage. Although both pilots reported the fuel gauges indicated 20 gallons of fuel remaining on each side when the engines stopped producing power, the flight instructor noted that there was no fuel in the airplane at the time of the accident. In addition, according to a Federal Aviation Administration inspector who responded to the accident site, both fuel tanks were breached and there was no evidence of fuel spillage.
Probable cause:
A dual total loss of engine power as a result of fuel exhaustion.

Circumstances:
The pilot departed on an instrument flight rules cross-country flight with three passengers. While enroute at a cruise altitude about 6,000 ft mean sea level (msl), the pilot discussed routing and weather avoidance with the controller. The controller advised the pilot there was a gap in the line of weather showing light precipitation, and that the pilot could pass through it and then proceed on course. The controller assigned the pilot a heading, which the pilot initially acknowledged, but shortly thereafter, he advised the controller that the airplane was pointed directly at a convective cell. The controller explained that the heading would keep the pilot out of the heavy precipitation and that he would then turn the airplane through an area of light precipitation. The pilot responded, saying that the area seemed to be closing in fast, the controller acknowledged and advised the pilot if he did not want to accept that routing, he could be rerouted. The pilot elected to turn toward a gap that he saw and felt he could fly straight through it. The controller acknowledged and advised the pilot that course would take him through moderate precipitation starting in about one mile extending for about four miles; the pilot acknowledged. Radar information indicated that the airplane entered an area of heavy to very heavy precipitation, likely a rain shower updraft, while in instrument meteorological conditions, then entered a right, descending spiral and broke up in flight. Examination of the wreckage revealed no evidence of a preaccident malfunction or failure that would have prevented normal operation. The airplane was equipped with the capability to display weather radar "mosaic" imagery created from Next Generation Radar (NEXRAD) data and it is likely that the pilot was using this information to navigate around precipitation when the airplane encountered a rain shower updraft with likely severe turbulence. Due to latencies inherent in processes used to detect and deliver the NEXRAD data from the ground site, as well as the frequency of the mosaic-creation process used by the service provider, NEXRAD data can age significantly by the time the mosaic image is created. The pilot elected to navigate the hazardous weather along his route of flight based on the data displayed to him instead of the routing suggested by the controller, which resulted in the penetration of a rain shower updraft, a loss of airplane control, and a subsequent inflight breakup.
Probable cause:
The pilot’s encounter with a rain shower updraft and severe turbulence, which resulted in a loss of airplane control and an inflight breakup. Contributing to the accident was the pilot’s reliance on outdated weather information on his in-cockpit weather display.

Circumstances:
While on an instructional flight in icing and instrument meteorological conditions (IMC), the pilots indicated that they were having instrumentation difficulties to air traffic control. They initially reported a problem with the autopilot, then a navigational issue, which they later indicated were resolved, and finally they reported it was a problem with the left side attitude indicator. After air traffic control cleared them to their destination, the airplane entered a descending left turn, which continued into a 360° descending turn. An inflight breakup resulted, with the wreckage being scattered over 7,000 ft of wooded terrain. Examination of the engines revealed there were no anomalies that would have precluded normal operation prior to the accident. Control cable continuity was established from the flight controls in the cockpit to all flight control surfaces through multiple overload failures. The pitot-static system was examined, and no blockages were noted. Since there was rotational scoring noted on the vertical gyro and the directional gyro, it’s likely they were operating at the time of the accident. Furthermore, the left side attitude indicator examination revealed that there were no anomalies with the instrument. Examination of the deice valves for the deicing boots revealed that the left wing deice valve did not operate. Corrosion was visible in all three valves and it could not be determined if the corrosion was a result of postimpact environmental exposure. Furthermore, since the cockpit switch positions were compromised in the accident, it could not be determined if the pilots were operating the deicing system at the time of the accident. However, most of the pilot reports (PIREPs) in the area indicated light icing and the airplane performed a 6,000 ft per minute climb just before the loss of control. Given this information, it is unlikely the icing conditions made the airplane uncontrollable. A review of the pilots’ flight experience revealed that the pilot in the left seat did not hold a type rating for the accident airplane model but was scheduled to attend flight training to obtain such a type rating. The pilot in the right seat, who also held a flight instructor certificate, did hold a type rating for the airplane. Given that the remarks section of the filed flight plan described the flight as a “training flight” and the left-seat pilot’s plan to obtain a type rating for the accident airplane model, it is likely the pilot in the left seat was the flying pilot for the majority of the flight. Although the right-seat pilot's autopsy noted coronary artery disease, the condition was poorly described. The circumstances of the accident are not consistent with sudden physical impairment or incapacitation; therefore, it is unlikely it contributed to the event. Toxicology testing identified diphenhydramine, which can cause significant sedation, in the right-seat pilot’s blood. However, the level present at the time of the accident was too low to quantify. Therefore, it is unlikely effects from diphenhydramine contributed to the accident. Prior to entering the descending right turn, air traffic control noted that the airplane was not following assigned headings and altitudes and the pilots’ reported having autopilot problems. Subsequently, the pilots’ reported they were using the right attitude indicator as they had difficulties with the left-side indicator. Information was insufficient to evaluate whether the reported difficulties were the result of a malfunction of the autopilot or the pilots’ management of the autopilot system. However, the reported difficulties likely increased the pilots’ workload, may have diverted their attention while operating in IMC and icing conditions, resulting in task saturation, and may have increased their susceptibility to spatial disorientation. It is also possible that the onset of spatial disorientation was the beginning of the pilots’ difficulties maintaining the airplane’s flight track and what they perceived to be an instrumentation problem. Regardless, since the left seat pilot was not rated to fly the airplane, the right seat pilot’s workload would have increased by having to diagnose the issue, assess the situation, and maintain positive airplane control. The airplane’s track data are consistent with the known effects of spatial disorientation, leading to an inflight loss of control and subsequent inflight breakup.
Probable cause:
The pilots’ loss of control in flight in freezing instrument meteorological conditions due to spatial disorientation and the cumulative effects of task saturation.

Circumstances:
The pilot departed on an instrument flight rules flight into instrument meteorological conditions (IMC). Radar data indicated that the airplane entered a left turn after takeoff, consistent with the pilot's instrument clearance. As the airplane climbed to an altitude about 2,410 ft above ground level, its rate of climb increased from about 3,500 ft per minute to 9,600 ft per minute, the stick shaker activated, and the airplane decelerated to about 75 knots. The airplane then entered a descending right turn and rolled inverted before impacting terrain about 1 mile from the airport. All major components of the airplane were located at the accident site, and examination of the wreckage revealed no anomalies with the airplane that would have precluded normal operation. The weather conditions about the time of the accident included an overcast cloud ceiling about 600 ft above ground level. It is likely that the pilot became spatially disoriented after entering the cloud layer, which resulted in the airplane's high rate of climb, rapid loss of airspeed, and a likely aerodynamic stall. The steep descending right turn, the airplane's roll to an inverted attitude, and the high-energy impact are also consistent with a loss of control due to spatial disorientation.
Probable cause:
The pilot's loss of airplane control due to spatial disorientation during initial climb in instrument meteorological conditions.

Circumstances:
On 2 May 2018, at approximately 1127 hours local time (L), the Mishap Aircraft (MA), a WC-130H, tail number 65-0968, assigned to the Puerto Rico Air National Guard, 156th Airlift Wing (156 AW), located at Muñiz Air National Guard Base, Puerto Rico, crashed approximately 1.5 miles northeast of Savannah/Hilton Head International Airport (KSAV), Georgia. All nine members aboard the MA—Mishap Pilot 1 (MP1), Mishap Pilot 2, Mishap Navigator, Mishap Flight Engineer, and Mishap Loadmaster (collectively the “Mishap Crew (MC)”), and four mission essential personnel, Mishap Airman 1, 2, 3, and 4—perished during the accident. The MC’s mission was to fly the MA to the 309th Aerospace Maintenance and Regeneration Group at Davis-Monthan Air Force Base, Arizona (commonly referred to as the “Boneyard”), for removal from service. The MA had been at KSAV for almost a month, since 9 April 2018, to undergo prescheduled fuel cell maintenance and unscheduled work on engine number one by 156 AW maintenance personnel using the facilities of the 165th Airlift Wing. During takeoff roll, engine one revolutions per minute (RPM) fluctuated and did not provide normal RPM when MP1 advanced the throttle lever into the flight range for takeoff. Approximately eight seconds prior to aircraft rotation, engine one RPM and torque significantly decayed, which substantially lowered thrust. The fluctuation on roll and significant performance decay went unrecognized by the MC until rotation, when MP1 commented on aircraft control challenges and the MA veered left and nearly departed the runway into the grass before it achieved flight. The MA departed KSAV at approximately 1125L. As the MC retracted the landing gear, they identified the engine one RPM and torque malfunction and MP1 called for engine shutdown. However, the MC failed to complete the Takeoff Continued After Engine Failure procedure, the Engine Shutdown procedure, and the After Takeoff checklist as directed by the Flight Manual, and the MA’s flaps remained at 50 percent. Additionally, MP1 banked left into the inoperative engine, continued to climb, and varied left and right rudder inputs. At an altitude of approximately 900 feet mean sea level and 131 knots indicated air speed, MP1 input over nine degrees of left rudder, the MA skidded left, the left wing stalled, and the MA departed controlled flight and impacted the terrain on Georgia State Highway 21.
Probable cause:
The board president found, by a preponderance of the evidence, the cause of the mishap was MP1’s improper application of left rudder, which resulted in a subsequent skid below three-engine minimum controllable airspeed, a left-wing stall, and the MA’s departure from controlled flight. Additionally, the board president found, by a preponderance of the evidence, the MC’s failure to adequately prepare for emergency actions, the MC’s failure to reject the takeoff, the MC’s failure to properly execute appropriate after takeoff and engine shutdown checklists and procedures, and the Mishap Maintainers’ failure to properly diagnose and repair engine number one substantially contributed to the mishap.

Circumstances:
The private pilot departed on an instrument flight rules flight plan in his twin-engine turbojet airplane. The flight was uneventful until the air traffic controller amended the flight plan, which required the pilot to manually enter the new routing information into the GPS. A few minutes later, the pilot told the controller that he was having problems with the GPS and asked for a direct route to his destination. The controller authorized the direct route and instructed the pilot to descend from 22,000 ft to 6,000 ft, during which time the sound of the autopilot disconnect was heard on the cockpit voice recorder (CVR). During the descent, the pilot told the controller that the airplane had a steering problem and was in the clouds. The pilot was instructed to descend the airplane to 4,100 ft, which was the minimum vectoring altitude. The airplane continued to descend, entered visual meteorological conditions, and then descended below the assigned altitude. The controller queried the pilot about the airplane's low altitude and instructed the pilot to maintain 4,100 ft. The pilot responded that he was unsure if he would be able to climb the airplane back to that altitude due to steering issues. The controller issued a low altitude warning and again advised the pilot to climb back to 4,100 ft. The pilot responded that the autopilot was working again and that he was able to climb the airplane to the assigned altitude. The controller then instructed the pilot to change to another radio frequency, but the pilot responded that he was still having a problem with the GPS. The pilot asked the controller to give him direct routing to the airport. A few minutes later, the pilot told the controller that he was barely able to keep the airplane straight and its wings level. The controller asked the pilot if he had the airport in sight, which he did not. The pilot then declared an emergency and expressed concerns related to identifying the landing runway. Afterward, radio contact between the controller and the pilot was lost. Shortly before the airplane impacted the ground, a witness saw the airplane make a complete 360° roll to the left, enter a steep 90° bank to the left, roll inverted, and enter a vertical nose-down dive. Another witness saw the airplane spiral to the ground. The airplane impacted the front lawn of a private residence, and a postcrash fire ensued.The pilot held a type rating for the airplane, but the pilot's personal logbooks were not available for review. As a result, his overall currency and total flight experience in the accident airplane could not be determined. The airplane was originally certified for operations with a pilot and copilot. To obtain an exemption to operate the airplane as a single pilot, a pilot must successfully complete an approved single-pilot exemption training course annually. The accident airplane was modified, and the previous owner was issued a single-pilot conformity certificate by the company that performed the modifications. However, there was no record indicating that the accident pilot received training under this exemption. Several facilities that have single-pilot exemption training for the accident airplane series also had no record of the pilot receiving training for single-pilot operations in the accident airplane. Therefore, unlikely that the pilot was properly certificated to act as a single-pilot. The GPS was installed in the airplane about 3.5 years before the accident. A friend of the pilot trained him on how to use the GPS. The friend said that the pilot generally was confused about how the unit operated and struggled with pulling up pages and correlating data. The friend of the pilot had flown with him several times and indicated that, if an air traffic controller amended a preprogrammed flight plan while en route, the pilot would be confused with the procedure for amending the flight plan. The friend also said the pilot depended heavily on the autopilot, which was integrated with the GPS, and that he would activate the autopilot immediately after takeoff and deactivate it on short final approach to a runway. The pilot would not trim the airplane before turning on the autopilot because he assumed that the autopilot would automatically trim the airplane, which led to the autopilot working against the mis-trimmed airplane. The friend added that the pilot was "constantly complaining" that the airplane was "uncontrollable." A postaccident examination of the airplane and the autopilot system revealed no evidence of any preimpact deficiencies that would have precluded normal operation. This information suggests that pilot historically had difficulty flying the airplane without the aid of the autopilot. When coupled with his performance flying the airplane during the accident flight without the aid of the autopilot, it further suggests that the pilot was consistently unable to manually fly the airplane. Additionally, given the pilot's previous experience with the GPS installed on the airplane, it is likely that during the accident flight the pilot became confused about how to operate the GPS and ultimately was unable to properly control of the airplane without the autopilot engaged. Based on witness information, it is likely that during the final moments of the flight the pilot lost control of the airplane and it entered an aerodynamic stall. The pilot was then unable to regain control of the airplane as it spun 4,000 ft to the ground.
Probable cause:
The pilot's failure to maintain adequate airspeed while manually flying the airplane, which resulted in the airplane exceeding its critical angle of attack and experiencing an aerodynamic stall. Contributing to the accident was the pilot's inability control the airplane without the aid of the autopilot.

Circumstances:
The 69-year-old commercial pilot was making a personal cross-country flight in the newly purchased airplane. When the airplane was on final approach to the destination airport in night visual meteorological conditions, airport surveillance video showed it pitch up and roll to the right. The airplane then descended in a nose-down attitude to impact in a ravine on the right side of the runway. During the descent over the ravine the right wing came in contact with a powerline that briefly cut power to the airport. Postaccident examination of the airframe, engines, and their components revealed no evidence of mechanical anomalies or malfunctions that would have precluded normal operation. The pilot's toxicology findings identified five different impairing medications: clonazepam, temazepam, hydrocodone, nortriptyline, and diphenhydramine. Although the results were from cavity blood and may not accurately reflect antemortem levels, the hydrocodone, temazepam, and diphenhydramine levels were high enough to likely have had some psychoactive effects. While the exact effects of these drugs in combination are not known, it is likely that the pilot was impaired to some degree by his use of this combination of medications, which likely contributed to his failure to maintain control of the airplane.
Probable cause:
The pilot's failure to maintain control of the airplane during a night visual landing approach. Contributing to the accident was the pilot's impairment due to his use of a combination of medications.
