Circumstances:
While on a night approach to Copenhagen-Kastrup Airport runway 22L, the right engine failed. The crew was able to feather the right propeller but the nose gear failed to deploy. Manual recycling was ineffective and the crew continued the approach. The aircraft landed on its nose, rolled for few dozen meters and came to rest on the main runway. Both pilots escaped uninjured and the aircraft was damaged beyond repair.
Probable cause:
Failure of the right engine caused by the failure of the turbine assembly retention guide vane. This caused a reduction of the hydraulic pressure, preventing the nose gear to be lowered.

Circumstances:
During the last segment on approach to Ho Chi Minh-Ville-Tan Son Nhat Airport, at a height of about 30 feet, the aircraft lost height, causing the left main gear to struck the ground short of runway threshold. The aircraft then landed hard and came to a halt on the main runway. All 79 occupants were evacuated, among them five passengers were injured.
Probable cause:
It is believed the aircraft lost height on short final due to an insufficient speed.
The following contributing factors were reported:
- Poor planned approach on part of the crew.
- Poor crew coordination.
- Lack of supervision and crew cross checks.

Circumstances:
While executing a VOR approach, on a dark, foggy night, depth perception and ground contact were lost when the landing lights were turned on short final. A hard landing resulted, before corrective action became effective, resulting in wing spar, engine mounting support and propeller damage. The runway, and entire airport was covered with about 3 inches of mirror smooth ice, causing considerable glare. All four occupants escaped uninjured.
Probable cause:
A restricted visual outlook and go-around was not performed by the pilot. Factors related to the accident were a dark night, fog and glare, ice covered runway and whiteout conditions.

Circumstances:
The pilot reported that shortly after lifting off, the airplane began decelerating slowly. He thought the throttles had retarded; however, all of the engine instruments indicated takeoff power. Realizing that he could not return to the airport, the pilot selected a forced landing area and aimed the airplane between two trees. Investigation revealed that both props were at or near feather pitch angles at impact and being driven under power. Both engines had been changed immediately prior to the flight and both ground idle stops had been adjusted after the engine change with the left engine being slaved to the right. The system operated off of a squat switch on the right gear. Misriging of the right engine would be reflected in the left and allow oil pressure to be vented from the domes, which in turn would allow the propeller cylinder springs to drive the props toward feather as the right strut extended during takeoff. The pilot, sole on board, was seriously injured.
Probable cause:
The loss of thrust due to the propeller's feathering on liftoff as a result of improper adjustments made during an engine change. A factor was the lack of suitable terrain to which the pilot could execute a forced landing.

Circumstances:
The Romanian Presidential Airplane was engaged in a series of tests prior to an official flight to China within two days. The crew consisting of pilots and engineers completed several circuits in the region of Bucharest-Otopeni Airport and was preparing to land when the aircraft rolled to the left on short final, causing both left engines n°1 and 2 to struck the runway surface. Fuel line ruptured and fuel ignited. The crew initiated an emergency braking procedure, vacated the runway by a taxiway and stopped the aircraft that was bursting into flames. All 13 occupants escaped uninjured while the aircraft was damaged beyond repair.

Circumstances:
A pilot (whose instrument currency could not be determined) took off at night in IMC. Shortly after takeoff, the aircraft crashed about 1.5 mile from the departure end of the runway. There was evidence that it impacted in an 85° right bank, nose down attitude at high speed. No preimpact part failure was found during the investigation; however, during a pre-purchase inspection on 10/16/90, several discrepancies were noted. These included an inop flight director, an autopilot malfunction and a misrigged flight control system that allowed the control wheel to indicate a left turn when the aircraft was in level flight. There was no record of these being repaired. Records showed the pitot-static system was last tested on 3/24/88. The pilot was taking sine-aid and tylenol for a chronic sinus infection. Although tox checks indicated the presence of 50.7 ug/ml of pseudoephedrine and 36.4 ug/ml of acetaminophen in the pilot's urine, none was found in his blood. The sinus cond could have affected the pilot's balance and equilibrium. All six occupants were killed.
Probable cause:
The pilot's failure to maintain control of the aircraft, due to spatial disorientation. Factors related to the accident were: darkness, adverse weather conditions, and the pilot's physical impairment from the chronic sinus infection.

Circumstances:
The flight departed Cold Bay for the approximately 15 minutes flight to False Pass. There are no weather reporting facilities at False Pass. Cold Bay weather was 4,500 feet overcast, light rain and fog; forecast called for frequent ceilings below 1,000 feet. Wreckage located between two mountains. False Pass weather estimated 400 feet overcast, 2-3 miles in rain and fog, winds 25-30 knots. Fishing boat captain in area estimated winds down the mountain at 60 mph or greater.
Probable cause:
The pilot's improper decision to continue flight into an area of mountainous terrain and adverse weather conditions. The terrain and weather were factors.
