Landing (descent or approach)

The approach to Hanamaki Airport was completed by the copilot. On short final, eight seconds prior to landing on runway 02, the aircraft was caught by downdrafts and windshear. Three seconds prior to touchdown, the captain regained control but this was too late. The aircraft landed hard, right main gear first. It rolled for about 1,860 metres before coming to rest on the runway, bursting into flames. All 76 occupants were rescued, among them 20 were injured. A fire erupted under the right wing following a tank rupture.

At the time flight AA102 landed at DFW Airport, it was raining and there were numerous thunderstorms in the area. Shortly after touchdown on runway 17L, the pilot loss directional control when the airplane began to weathervane and the captain failed to use sufficient rudder control to regain the proper ground track. The airplane eventually departed the right side of the runway. At the time of landing the wind (a cross wind) was blowing at 15 knots with gusts approximately 5 knots above the steady wind speed. The aircraft was damaged beyond repair and all 202 occupants were evacuated, among them 40 were injured, two seriously.

The aircraft was operating a freight charter flight, cruising normally at an altitude of 20,000 ft (FL200), when, about 150 km south-east of Mackay, the left engine lost power and could not be restarted. During the subsequent landing on runway 14 at Mackay, the pilot attempted a single engine go-around when he suddenly had the (mistaken) impression that the landing gear was not down. He temporarily lost control of the aircraft but recovered to touch down on the flight strip to the left of the runway, some 500 m before the runway end. During the landing roll, the landing gear collapsed and the aircraft sustained substantial damage.

The approach to Guatemala City-La Aurora Airport was completed in poor weather conditions with rain falls, a visibility of three miles below a 2,000 feet cloud ceiling. The crew was cleared to land on runway 19 with a tailwind component as the wind was from 030° at 8 knots. The aircraft landed 1,070 metres past the runway threshold (runway 19 is 2,763 metres long) at a speed that was 17 knots above Vref. The crew started the braking procedure and thrust reversers were deployed. At a distance of 300 metres from the runway end, the captain decided to veer off runway to the left. At a speed of 90 knots, the aircraft went through a perimeter fence, down an embankment and eventually came to rest into several houses. All 236 occupants evacuated safely while the aircraft was damaged beyond repair. Three people on the ground were slightly injured.

The aircraft was on an air ambulance (EMS) flight and was cleared for the ILS runway 08 approach at Casper, WY. Radar data showed the aircraft tracking and descending normally on the DME arc, until it was below radar coverage for the area. Subsequently, it collided with the top of a ridge, along the localizer centerline, before reaching the outer marker, about 8 miles from the airport. Elevation of the crash site was about 5,800 feet; minimum descent altitude before intercepting the ILS glide slope was 7,100 feet; crossing altitude at the outer marker was 6,700 feet. All four occupants were killed, a patient, two doctors and a pilot.

The aircraft landed nose first at Stepanavan Airport. Upon impact, the nose gear collapsed and the aircraft slid for about 600 metres before coming to rest. All 32 occupants evacuated safely and the aircraft was damaged beyond repair.

N500AK encountered icing in flight before start of ILS approach. Radar data showed that before reaching outer marker, it slowed in a manner that was consistent with a power reduction (or partial loss of power), then it entered a steep descent and crashed. Examination revealed engines were not operating at impact and that propellers had been feathered. No preimpact part failure or malfunction of engines, propellers or anti-ice system was found. There was evidence that engine inlet anti-ice annunciator lights and stability augmentation system (SAS) fault warning light were illuminated during impact. The engine manufacturer reported that flameouts had occurred in other aircraft, during or following operation in icing conditions, sometimes after descent into warmer air. Flight manual noted that if icing was encountered with anti-ice system off, select continuous ignition and then select engine and propeller heat (1 engine at a time, ensuring first engine was operating satisfactorily before selecting second engine) and engage sas heat. All four occupants were killed.

The crew miscalculated speed and propeller pitch on approach to Yuzhno-Kurilsk. The seaplane landed at an excessive speed and while making a right turn in shallow water (1,6 metre deep), the right float struck the water surface and was torn off. In the meantime, the aircraft collided with a sandbank, causing a tear in the fuselage. Water entered the cabin and the aircraft came to rest about 20 metres from the shore. All 38 occupants escaped uninjured and the aircraft was damaged beyond repair.

During the days prior to the accident, various problems with the pitch-trim system and the horizontal stabilizers were noticed and reported. Repairs were conducted by technicians from the Royal Thai Air Force but apparently, not according to the Boeing published procedures, so a Boeing engineer was dispatched in Thailand to proceed to controls and tests. On approach to Muang Khon Kaen Airport, the aircraft started to pitch up and down then stalled. The crew increased engine power and regained control for few seconds when the aircraft stalled a second time few seconds later. The crew elected to regain control and to reduce the rate of descent when the aircraft entered an uncontrolled descent and crashed in a rice paddy field located few km from the airport. The aircraft was destroyed and all six occupants were killed. The aircraft has the dual registration 33-333 (military) and HS-TGQ (civil).

The crew was engaged in a local training flight at Budapest-Ferihegy Airport. In unknown circumstances, the crew was forced to attempt an emergency landing when the aircraft crashed near the control tower, bursting into flames. Both occupants were injured.
