Circumstances:
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.
Probable cause:
The report concludes that the engine power loss was caused by failure of the fuel pump high pressure relief valve. The pilot, believing that the landing gear was still retracted, initiated action to avoid a wheels-up landing. This action was initiated too late in the landing approach for a successful outcome.

Circumstances:
After landing on a poor condition runway, the aircraft deviated to the left then veered off runway. The aircraft lost its landing gear and came to rest few dozen metres further. All 10 occupants escaped injured and the aircraft was written off. The accident occurred at Mogadishu-South Airport sometimes called Mogadishu-West Airfield or KM50. Its narrow and limited runway is made up of chippings and pebbles and is not equipped with a lighting system or any drainage system and is very poorly maintained.

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:
After takeoff from Örnsköldsvik Airport, while climbing to an altitude of 7,000 feet, the left engine oil pressure warning light sounded. The crew shut down the engine but was unable to feather the propeller. Doing so, a fuse blew and only the right side of the instrument lights remained functional. After being cleared to return, the crew completed a turn but on approach, he was forced to use full elevator and rudder deflection because the left propeller could not be feathered. Misaligned, the aircraft landed 30 meters to the left of the runway then rolled few dozen meters before coming to rest. All 17 occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Because the left propeller could not be feathered, this created drag the the crew was forced to compensate with trim and rudder deflection, causing the aircraft to be misaligned on final approach.
The following contributing factors were reported:
- An oil leak in the left engine during initial climb forced the crew to shut it down,
- Power supply problems caused by the left side not having been isolated from the right side,
- Wrong adjustment of the speed control trigger,
- Inadequate following of the checklist.

Circumstances:
Following a night takeoff at Montluçon-Guéret Airport, while in initial climb, the aircraft nosed down and struck the ground 600 meters past the runway end. It slid for few dozen meters, collided with bushes and eventually came to rest, bursting into flames. All four occupants were killed. It appears that the Stall Avoidance System (SAS) had activated, resulting in the stick pusher activation at a critical altitude. The Metro's SAS system, as well as the SAS system on this particular aircraft, had a history of problems. These problems resulted in several NTSB Safety Recommendations (A-84-66, A-88-154). The copilot was at controls at the time of the accident.
Crew:
Gérard Van Der Veecken, pilot,
Christian Rémondon, copilot.
Passengers:
Robert Aupetit,
Patrick Desdoit.
Probable cause:
The accident resulted from a reduction in the attitude of the airplane causing a downward trajectory in the moments that followed the takeoff. It is likely that this decrease in attitude is due to an untimely triggering of the stick pusher. The absence of a recorder and the complete destruction of the SAS (apart from angle of attack vane and its transmitter) did not prove this hypothesis. With or without inadvertent triggering of the stick pusher, the imprecision of the right horizon and the absence of external visual references played an important role in this accident.

Probable cause:
Failure of the left engine shortly after takeoff for unknown reasons.

Aircraft flight hours:

Circumstances:
The aircraft had descended through a cloud layer enroute for the scheduled landing at IAD and according to the crew had picked up some trace rime ice on its wing surfaces. Although pitot and sas (stall avoidance system) heat were used the captain elected not to use engine inlet anti-ice. Just inside the outer marker the left engine lost power followed shortly by the right engine. The captain was able to set the aircraft down in an open field where the gear collapsed during the landing roll. The engines were successfully run-up at the Garrett facility. The flight manual contains a warning and a note stating that engine heat and continuous ignition must be used after leaving icing conditions until the pilot is confident that any significant residual ice will not be ingested into the engines. Ice was found lying beneath the right wing which matched the curvature of the leading edge of the wing. A round conical shaped piece of ice was found along the wreckage path which matched the nose of the propeller spinner.
Probable cause:
Occurrence #1: loss of engine power (total) - nonmechanical
Phase of operation: approach - faf/outer marker to threshold (ifr)
Findings
1. All engines
2. (f) weather condition - icing conditions
3. (c) in-flight planning/decision - improper - pilot in command

Circumstances:
The crew was completing a positioning flight from Lyon-Satolas Airport to Le Puy-Loudes Airport, Haute-Loire. On final approach by night, at an altitude of 500 feet, the crew positioned both propellers to fine pitch when both engines failed simultaneously. The airplane stalled and crash landed in an open field located few hundred meters short of runway threshold. Both pilots escaped with minor injuries while the aircraft was damaged beyond repair.
Probable cause:
It was determined that weather conditions were considered as marginal at the time of the accident with icing conditions. Both engines failed after the crew positioned both propellers to fine pitch due to an excessive accumulation of ice. The crew failed to activate the engine deicing systems and also failed to restart the engine. It was also reported there was no antifreeze liquid used.

Circumstances:
The right engine failed during takeoff immediately after rotation 3,000 feet down the 7,002 feet runway 16. The pilot continued the flight and the landing gear remained extended. The unauthorized pilot rated passenger made transmissions to the tower. Witnesses reported that the aircraft reached approximately 150 feet then descended into trees 20° to the right of runway centerline and 3,000 feet south of the airport. The pre-1979 3rd stage stator assembly in the right engine did not have the latest manufacture welding process/inspection and failed causing the uncontained turbine failure. Instruments in the wreckage indicated that an undeterminable loss of electrical power occurred at the time of engine failure. Performance data indicated that a safe landing could have been made on the remaining runway past the point of engine failure. Both occupants were killed.
Probable cause:
Occurrence #1: loss of engine power (partial) - mech failure/malf
Phase of operation: takeoff - initial climb
Findings
1. (f) turbine assembly, nozzle retention - inadequate
2. (f) acft/equip, inadequate design - manufacturer
