Beechcraft 90 King Air

The pilot was conducting a post-maintenance test flight. An overhauled engine had been installed on the right side of the airplane, and both propeller assemblies had been subsequently re-rigged. Ground checks were satisfactory, although the right engine propeller idled 90-100 rpm higher than the left engine propeller. Test flight engine start and run-up were conducted per the checklist, with no anomalies noted. Takeoff ground roll and initial climb were normal; however, when the airplane reached about 100 feet, it stopped climbing and lost airspeed. The pilot could not identify the malfunction, and performed a forced landing to rough, hilly terrain. Upon landing, the landing gear collapsed and the engine nacelles were compromised. The airplane subsequently burned. Post-accident examination of the airplane revealed that the propeller beta valves of both engines were improperly rigged, and that activation of the landing gear squat switch at takeoff resulted in both propellers going into feather. The maintenance personnel did not have rigging experience in airplane make and model. As a result of the investigation, the manufacturer clarified maintenance manual and pilot handbook procedures.

The twin engine aircraft departed Paris-Le Bourget Airport at 1309LT on a flight to Reims-Champagne with two pilots on board, one instructor and one pilot that should complete a transition program. While descending at an altitude of 2,000 to Reims-Prunay Airport, the crew informed ATC that he would perform an exercise consisting of a go-around procedure with the simulation of an engine failure. On a left downwind approach to runway 25, the crew started the exercise when the aircraft rolled to the left, lost height and crashed in an open field, bursting into flames. The wreckage was found 425 metres short of runway 25 and both pilots were killed.

The twin engine aircraft departed a private strip in Itapuranga on a flight to Goiânia, carrying seven passengers and two pilots. About 10 minutes after takeoff, while in cruising altitude, the captain informed ATC about the failure of the right engine. Because the flight was short (25 minutes in total), he decided to continue to Goiânia. Twelve minutes later, the left engine failed as well. The crew declared an emergency and as he was unable to reach Goiânia Airport, he attempted an emergency landing in a pasture. The aircraft crash landed 13 km short of runway 14 threshold. All nine occupants were rescued, among them seven were injured, three seriously.

On final approach to Bursa-Yenisehir Airport, the pilot encountered poor weather conditions. Due to low visibility, he was unable to establish a visual contact with the approach and runway lights and initiated a go-around procedure. While completing a circuit, the twin engine aircraft struck the top of a hill located near the airport and crashed. A passenger was killed while four other occupants were injured.

The twin engine airplane departed Ankara-Esenboğa Airport on a flight to Istanbul with three passengers and one pilot on board, among the operator's President. Few minutes after takeoff, while flying in poor weather conditions due to snow falls, the aircraft went out of control and crashed in a field located in Güdül, about 65 km west of Ankara-Esenboğa Airport. All four occupants were killed.

The pilot requested and received clearance to execute the SDF approach, and was instructed to maintain 4,000 feet until established on the approach. Radar data revealed the airplane was never established on the approach, and started to descend before reaching the IAF. The airplane passed the IAF at 2,900 feet, and continued in a descending left hand turn into unprotected airspace. The airplane disappeared from radar at 1,900 feet, as it completed 180 degrees of turn. The turn did not match any of the four instrument approaches to the airport. The airplane struck a guy wire on a lighted communications antenna 3.3 MN southeast of the airport on a heading of 360 degrees. No evidence of a mechanical failure or malfunction of the airplane or its systems was found. A flight check by the FAA confirmed no navigation signal was received for the approach, which had been turned off and listed as out of service for over 4 years. In addition, the pilot did not report the lack of a navigation signal to ATC or execute a missed approach. Interviews disclosed the ATC controller failed to verify the approach was in service before issuing the approach clearance.
