Circumstances:
Prior to the flight, the pilot preflighted the airplane and recalled observing the fuel gauge indicating full; however, he did not visually check the fuel tanks. The airplane departed and the en route portion of the flight was uneventful. During the downwind leg of the circling approach, the engines began to surge and the pilot added full power and turned on the fuel boost pumps. While abeam the approach end of the runway on the downwind leg, the engines again started to surge and subsequently lost power. He executed a forced landing and the airplane impacted terrain short of the runway. A postaccident examination by Federal Aviation Administration inspectors revealed the fuselage was buckled in several areas, and the left wing was crushed and bent upward. The fuel tanks were intact and approximately one cup of fuel was drained from the single fuel sump. Fueling records indicated the airplane was fueled 3 days prior to the accident with 135 gallons of fuel or approximately 4 hours of operational time. Flight records indicated the airplane had flown approximately 4 hours since refueling when the engines lost power.
Probable cause:
The pilot’s improper fuel management which resulted in a loss of engine power due to fuel exhaustion.

Circumstances:
On his first Instrument Landing System (ILS) approach, the pilot initially flew through the localizer course. The pilot then reestablished the airplane on the final approach course, but the airplane’s altitude at the decision height was about 500 feet too high. He executed a missed approach and received radar vectors for another approach. The airplane was flying inbound on the second ILS approach when a witness reported that he saw the airplane about 150 feet above the ground in about a 60-degree nose-low attitude with about an 80-degree right bank angle. The initial ground impact point was about 2,150 feet west of the runway threshold and about 720 feet north (left) of the extended centerline. The cloud tops were about 3,000 feet with light rime or mixed icing. The flap jack screws and flap indicator were found in the 5-degree flap position. The inspection of the airplane revealed no preimpact anomalies to the airframe, engines, or propellers. A radar study performed on the flight indicated that the calibrated airspeed was about 130 knots on the final approach, but subsequently decreased to about 95–100 knots during the 20-second period prior to loss of radar contact. According to the airplane’s flight manual, the wings-level power-off stall speed at the accident aircraft’s weight is about 91 knots. The ILS approach flight profile indicates that 20 degrees of flaps should be used at the glide slope intercept while maintaining 120 knots minimum airspeed. At least 20 degrees of flaps should be maintained until touchdown. The “No Flap” or “5 Degrees Flap Landing” flight profile indicates that the NO FLAP Vref airspeed is 115 knots calibrated airspeed minimum.
Probable cause:
The pilot's failure to maintain adequate airspeed during the instrument approach, which resulted in an aerodynamic stall and impact with terrain.

Circumstances:
The accident flight was the first flight following maintenance that included flight control cable rigging. The flight was also intended to provide cockpit familiarization for the first officer and the pilot observer, and as a training flight for the first officer. About one minute after takeoff, the first officer contacted the tower and stated that they needed to return to land. The airplane impacted a cornfield about one mile southwest of the approach end of the runway, and 2 minutes 40 seconds after the initiation of the takeoff roll. The cockpit voice recorder (CVR) indicated that, during the flight, neither the captain nor the first officer called for the landing gear to be raised, the flaps to be retracted, or the power levers to be reduced from full power. From the time the first officer called "rotate" until the impact, the captain repeated the word "pull" about 27 times. When the observer pilot asked, "Come back on the trim?" the captain responded, "There's nothing anymore on the trim." The inspection of the airplane revealed that the elevator trim cables were rigged improperly, which resulted in the trim cables being reversed. As a result, when the pilot applied nose-up trim, the elevator trim system actually applied nose-down trim. The flight crew was briefed on the maintenance work that had been performed on the airplane; therefore, when the captain’s nose-up trim inputs were affecting his ability to control the airplane, at a minimum, he should have stopped making additional inputs and returned the airplane to the configuration it was in before the problem worsened. An examination of the maintenance instruction cards used to conduct the last inspection revealed that the inspector's block on numerous checks were not signed off by the Required Inspection Item (RII) inspector. The RII inspector did not sign the item that stated: "Connect elevator servo trim tab cables and rig in accordance with Allison Convair [maintenance manual]...” The item had been signed off by the mechanic, but not by the RII inspector. The card also contained a NOTE, which stated in bold type, "A complete inspection of all elevator controls must be accomplished and signed off by an RII qualified inspector and a logbook entry made to this effect." The RII inspector block was not signed off.
Probable cause:
The improper (reverse) rigging of the elevator trim cables by company maintenance personnel, and their subsequent failure to discover the misrigging during required post-maintenance checks. Contributing to the accident was the captain’s inadequate post-maintenance preflight check and the flight crew’s improper response to the trim problem.

Circumstances:
During the landing approach, a witness saw the twin-engine airplane slow and stall. The airplane crashed short of the runway, in a residential backyard. An airport manager flew with the pilot 8 days before the accident. The manager reported that during his flight the pilot flew the approach and landing with the aural stall warning horn activated. The manager advised the pilot of the aural warning, however no corrective action was taken by the pilot during that flight. An on-scene investigation revealed no preimpact mechanical anomalies. The pilot had about 12.6 hours of flight time in the accident airplane, of which 7.7 hours were dual instruction. Due to the lack of any mechanical problems with the airplane, the pilot's minimal experience in twin-engine airplanes, and his history of flying the airplane too slow, it is probable that he allowed the airspeed to decay below a safe speed, and inadvertently stalled it.
Probable cause:
The pilot's failure to maintain sufficient airspeed to avoid a stall during the landing approach.

Circumstances:
The cargo flight was departing on its fourth flight leg of a five-leg flight in night instrument conditions, which included a surface observation of light snow and a broken ceiling at 500 feet above ground level (agl). One pilot who departed just prior to the accident flight indicated that moderate snow was falling and that he entered the clouds about 200 feet agl. The accident airplane's wings and tail were de-iced prior to departure. Radar track data indicated the accident flight was about 45 seconds in duration. An aircraft performance radar study indicated that the airplane reached an altitude of about 1,130 feet mean sea level (msl), or about 400 feet above ground level, about 114 knots with a left bank angle of about 29 degrees. The airplane descended and impacted the terrain at an airspeed of about 155 knots, a pitch angle of -16 degrees, a left roll angle of 22 degrees, and a descent rate of 4,600 feet per minute. The study indicated that the engine power produced by the airplane approximately matched the engine power values represented in the pilot's operating handbook. The study indicated that the required elevator deflections were within the available elevator deflection range, and that the center-of-gravity (CG) position did not adversely affect the controllability of the airplane. The study indicated that the load factor vectors, the forces felt by the pilot, could have produced the illusion of a climb, even when the airplane was in a descent. The inspection of the airframe and engine revealed no anomalies that would have precluded normal operation.
Probable cause:
The pilot's failure to maintain aircraft control and collision avoidance with terrain due to spatial disorientation. Contributing to the accident were the low cloud ceiling and night conditions.

Circumstances:
The airplane was substantially damaged during an in-flight recovery after the captain attempted an intentional aileron roll maneuver during cruise flight and lost control. The cargo flight was being operated at night under the provisions of 14 CFR Part 135 at the time of the accident. The captain reported the airplane was "functioning normally" prior to the intentional aileron roll maneuver. The captain stated that the "intentional roll maneuver got out of control" while descending through flight level 200. The captain reported that the airplane "over sped" and experienced "excessive G-loads" during the subsequent recovery. The copilot
reported that the roll maneuver initiated by the captain resulted in a "nose-down unusual attitude" and a "high speed dive." Inspection of the airplane showed substantial damage to the left wing and elevator assembly.
Probable cause:
The pilot's failure to maintain aircraft control during an inflight maneuver which resulted in the design stress limits of the airplane being exceeded. A factor was the excessive airspeed
encountered during recovery.

Circumstances:
The small, twin-engine business jet was about 15 feet above the runway on takeoff, when a flock of birds from both sides of the runway flew up in front of the airplane. The number two engine "surged," and "loud reports" were heard before the copilot noted a complete loss of power on the number two engine instruments. The airplane climbed for about 10 seconds, before the copilot observed the gas producer (N1) gauge on the number one engine decay through 50 percent. The stall warning horn sounded, and the pilot adjusted the flight controls for landing. The airplane contacted the runway with the landing gear retracted, overran the runway, struck a fence, crossed a road, and came to rest in a cornfield about 1,000 feet beyond the initial point of ground contact. Post accident examination of both engines revealed evidence and damage consistent with multiple bird ingestion.
Probable cause:
The ingestion of multiple birds in each engine at takeoff, which resulted in a complete loss of engine power.

Circumstances:
The purpose of the flight was for the second pilot to perform an evaluation of the first pilot, who was recently designated by the operator as a backup pilot. Following several successful flights with and without passengers, the pilots discussed single engine operations, and the first pilot reduced the right engine's power to flight idle and feathered the propeller. During the final leg of the approach to landing, the airplane crossed over a fence near the runway threshold, and the first pilot pitched the airplane downward. The nose landing gear contacted the runway "hard," and the airplane began to bounce. After several bounces, the first pilot elected to abort the landing, increased power on the left engine to "full." As the first pilot pitched the airplane upward, it yawed to the right, "stalled," and impacted the ground.
Probable cause:
The pilot's improper flare and recovery from a bounced landing, which resulted in a stall and subsequent impact with the ground.

Circumstances:
The pilot was conducting a cargo flight in night instrument meteorological conditions, and was cleared for the ILS Runway 6L approach. The pilot reported that he was established on the localizer, and the control tower stated that the touchdown and mid-point "RVR" was 1,800 feet, and the roll-out "RVR" was 1,600 feet. The pilot also was instructed, and acknowledged, to make a right turn off the runway, after landing. There were no further communications from the airplane. The airplane's last radar target was observed at an altitude of 1,200 feet msl, and a ground speed of 130 knots. The airplane impacted trees, and came to rest inverted on airport property, on a bearing of 053 degrees, and a distance of 1/2 mile to the runway. Examination of the airplane did not reveal any pre-impact mechanical failures. A weather observation taken at the airport about the time of the accident included, winds from 140 degrees at 9 knots, 1/8 mile visibility, runway 06L visual range variable between 1,800, and 2,000 feet in fog, vertical visibility 100 feet, and a temperature and dew point 54 degrees F. The airport elevation was 1,009 feet msl. Review of the approach diagram for the ILS Runway 6L approach revealed a decision height of 1,198 feet msl, and an approach minimum of 1,800 feet runway visual range (RVR), or 1/2 mile visibility. The pilot had accumulated about 3,800 hours of total flight experience, which included about 350 hours in the same make and model as the accident airplane, and 250 total hours logged in instrument meteorological conditions.
Probable cause:
The pilot's failure to maintain adequate altitude\clearance while on approach, which resulted in an in-flight collision with trees. Factors in the accident were the fog and low ceiling conditions.

Circumstances:
The pilot departed in a Cessna 208B, and shortly after takeoff, he experienced a power loss. He set up for a forced landing and during the ground roll, the nose wheel sunk into the soft terrain and the airplane nosed over. Fuel was found in both wings; however, the fuel line between the fuel selector and the engine contained only trace amounts of fuel. One fuel selector was found in the OFF position, and the other fuel selector was mid-range between the OFF and ON positions. The airplane was equipped with an annunciator warning light and horn to warn if either fuel selector was turned off. The annunciator was popped out and did not make contact with the annunciator panel. The warning horn was checked and found to be inoperative, and the electrical circuitry leading to the horn was checked and found to be operative. The engine was test run with no problems noted. According to the Pilot's Operating Handbook, the position of the fuel selectors are to be checked three times before takeoff: including cabin preflight, before engine start, and before takeoff. The pilot reported that he departed with both fuel selectors on and had not touched them when the power loss occurred. A representative of Cessna Aircraft Company reported that there was sufficient fuel forward of the fuel selector valves to takeoff and fly for a few miles prior to experiencing fuel exhaustion.
Probable cause:
The pilot's failure to verify the position of the fuel selectors prior to takeoff, which resulted in a power loss due to fuel starvation. A factor was the failure of the fuel selector warning horn.
Final Report:
