Circumstances:
The airline transport pilot and two passengers departed in the twin-engine, pressurized airplane on a business flight in night instrument meteorological conditions. Shortly after takeoff, the airplane began to deviate from its assigned altitude and course. The controller queried the pilot, who responded that the airplane was "… a little out of control." After regaining control of the airplane, the pilot reported that he had experienced a "trim issue." The airplane continued on course and, about 13 minutes later, the pilot again reported a trim malfunction and said that he was having difficulty controlling the airplane. The flight's heading and altitude began to deviate from the course for the last 8 minutes of radar data and became more erratic for the last 2 minutes of radar data; radar and radio communication were subsequently lost at an altitude of about 18,300 ft in the vicinity of the accident site. Several witnesses reported hearing the airplane flying overhead. They all described the airplane as being very loud and that the engine sound was continuous up until they heard the impact. The airplane impacted a field in a relatively level attitude at high speed. The wreckage was significantly fragmented and the wreckage path extended about 1/4 mile over several fields. Examination of the available airframe and engine components revealed no anomalies that would have precluded normal operation of the airplane. The accident airplane was equipped with elevator, rudder, and aileron trim systems; however, not all components of the trim system and avionics were located or in a condition allowing examination. Although the airplane was equipped with an electric elevator trim and autopilot that could both be turned off in an emergency, the investigation could not determine which trim system the pilot was reportedly experiencing difficulties with. It is likely that the pilot was unable to maintain control of the airplane as he attempted to address the trim issues that he reported to air traffic control.
Probable cause:
An in-flight loss of control for reasons that could not be determined based on the available evidence.

Circumstances:
The commercial pilot reported that the purpose of the flight was to perform a check/orientation flight with the airline transport pilot (ATP), who was new to the area; the ATP was the pilot flying. The airplane was started, and an engine run-up completed. The commercial pilot reported that, during the takeoff roll, all of the gauges were in the “green.” After reaching an airspeed of 80 knots, the airplane lifted off the ground. About 350 ft above ground level (agl), the pilots felt the airplane “jolt.” The commercial pilot stated that it felt like a loss of power had occurred and that the airplane was not responding. He immediately shut off the boost pumps, and the ATP initiated a slow left turn in an attempt to return to the airport to land. The airplane descended rapidly in a nose-low, right-wing-low attitude and impacted the ground. A witness reported that he watched the airplane take off and that it sounded normal until it reached the departure end of the runway, at which point he heard a distinct “pop pop,” followed by silence. The airplane then entered an approximate 45-degree left turn with no engine sound and descended at a high rate with the wings rolling level before the airplane went out of sight. Another witness made a similar statement. Based on the witnesses’ statements and photographs of the twisted airplane at the accident site, it is likely that a total loss of engine power occurred and that, during the subsequent turn back to the airport, the ATP did not maintain sufficient airspeed and exceeded the airplane’s critical angle-of-attack, which resulted in an aerodynamic stall and impact with terrain. Although a postaccident examination of the airframe and engines did reveal an inconsistency between the cockpit control positions and the positions of the fuel shutoff valves on the sump tank, this would not have precluded normal operation. No other anomalies were found that would have precluded normal operation.
Probable cause:
The pilot’s failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle-of-attack after a total loss of engine power during the takeoff initial climb, which resulted in an aerodynamic stall and impact with terrain. The reason for the total loss of engine power could not be determined because an examination of the airframe and engines did not reveal any anomalies that would have precluded normal operation.

Circumstances:
The aircraft was destroyed when it impacted terrain in the Superstition Mountains near Apache Junction, Arizona. The commercial pilot and the five passengers were fatally injured. The airplane was registered to Ponderosa Aviation, Inc. (PAI) and operated by PAI under the provisions of 14 Code of Federal Regulations (CFR) Part 91 as a personal flight. Night visual meteorological conditions (VMC) prevailed, and no flight plan was filed. The airplane had departed Falcon Field (FFZ), Mesa, Arizona, about 1825 and was destined for Safford Regional Airport (SAD), Safford, Arizona. PAI’s director of maintenance (DOM) and the director of operations (DO), who were co owners of PAI along with the president, conducted a personal flight from SAD to FFZ. The DO flew the leg from SAD to FFZ under visual flight rules (VFR) in night VMC. After arriving at FFZ and in preparation for the flight back to SAD, the DOM moved to the left front seat to act as the pilot flying. The airplane departed FFZ about 12 minutes after it arrived. According to a witness, engine start and taxi-out appeared normal. Review of the recorded communications between the pilot and the FFZ tower air traffic controllers revealed that when the pilot requested taxi clearance, he advised the ground controller that he was planning an "eastbound departure." The flight was cleared for takeoff on runway 4R, and the pilot was instructed to maintain runway heading until advised, due to an inbound aircraft. About 90 seconds later, when the airplane was about 1.1 miles from the departure end of the runway, the tower local controller issued a "right turn approved" advisory to the flight, which the pilot acknowledged. Radar data revealed that the airplane flew the runway heading for about 1.5 miles then began a right turn toward SAD and climbed through an altitude of about 2,600 feet mean sea level (msl). About 1828, after it momentarily climbed to an altitude of 4,700 feet, the airplane descended to an altitude of 4,500 feet, where it remained and tracked in an essentially straight line until it impacted the mountain. The last radar return was received at 1830:56 and was approximately coincident with the impact location. The impact location was near the top of a steep mountain that projected to over 5,000 feet msl. Witnesses reported seeing a fireball, and law enforcement helicopters were dispatched.
Probable cause:
The pilot's failure to maintain a safe ground track and altitude combination for the moonless night visual flight rules flight, which resulted in controlled flight into terrain. Contributing to the accident were the pilot's complacency and lack of situational awareness and his failure to use air traffic control visual flight rules flight following or minimum safe altitude warning services. Also contributing to the accident was the airplane's lack of onboard terrain awareness and warning system equipment.
