Circumstances:
En route from Woleai Atoll to Yap Island, the pilot encountered marginal weather conditions and became lost. In adverse winds aloft (winds gusting up to 30 knots), both engines failed due to fuel exhaustion. The pilot attempted an emergency landing about 80 km east of Yap Island. All seven occupants were quickly rescued while the aircraft sank and was lost.
Probable cause:
Engine failure in normal cruise and subsequent ditching due to fuel exhaustion after the pilot became lost/disoriented. The following contributing factors were reported:
- Adverse winds aloft,
- Wind gusting up to 30 knots,
- Complete failure of both engines,
- Weather slightly worse than forecast,
- Forced landing off airport on water.

Circumstances:
The single engine airplane departed Kaitaia at 1134LT being ferried to Whangarei. En route, the pilot made a low pass over his parent's house located in the Mataraua Valley then completed a 360° probably to gain height when the airplane crashed in the bush about 8 miles southwest of Kaikohe. The aircraft was destroyed and the pilot, sole on board, was killed.
Probable cause:
The probable cause of this accident was the inability of the pilot to recover from a stall incurred while manoeuvering an aircraft with unfamiliar performance characteristics at a low level in hilly terrain.

Circumstances:
The aircraft was engaged on the return segment of a flight from Perth to Teutonic Bore, with an intended refuelling stop at Leonora. After embarking the two passengers and their baggage, the pilot started the engines and taxied for a take-off into the north, on the 1350 metre long main strip. The weather conditions were fine with a northerly surface wind of about 7 knots. The initial part of the take-off run was apparently normal but, after travelling some 400 metres and at about the point of rotation, one of the passengers noted an engine power surge. The take-off was continued, the aircraft became airborne and shortly afterwards the landing gear was retracted. After the aircraft had slowly climbed straight ahead to an altitude of about 200-300 feet above ground level, the passenger heard a marked change in the engine noise and felt the aircraft decelerating. The extent of the power loss and the absence of any yawing force indicated both engines had lost power simultaneously. Level flight straight ahead was reportedly maintained for an estimated 10 seconds and then the aircraft entered a descending left turn. At about this time the pilot, in response to a query from the passenger, advised that he intended to return to the airstrip but then stated "we're going down", or words to that effect. The terrain in the area was generally firm and flat. It was lightly covered with scrub and there was occasional small trees but a safe landing with only minimal damage was possible. When VH-KXY struck the ground the gear and flaps were retracted and the rate of descent was high. The aircraft was in a level attitude but yawed approximately 45 degrees to the right. After the initial impact, the aircraft slid across the ground on a track of 220 degrees magnetic for 67 metres before coming to rest. There was no post-impact fire. One passenger was able to exit via the cabin door by his own efforts. The other occupants were trapped in the wreckage and were rescued some 30 minutes later by persons who attended the accident. The pilot died shortly after being removed from the aircraft.
Probable cause:
The probable cause of the accident was that, following a substantial loss of power by both engines, the pilot did not carry out the procedures necessary for a safe forced landing. The cause of the loss of power by both engines has not been determined.

Circumstances:
Weather conditions at Esperance were fine; there was no cloud, visibility was in excess of 30 km and the surface wind was from the northwest at 5 to 10 knots. The aircraft entered the circuit on a left downwind leg for an approach to Runway 29. The flaps were lowered, firstly a quarter and then half-way, on the downwind leg and the landing gear was extended just before the aircraft turned onto a base leg. This configuration, and an airspeed of 133 knots (best single - engine rate of climb speed), was maintained until after the aircraft was straightened onto final approach. At an altitude of 1100 feet, the pilot considered he was at Decision Height and committed to land. He lowered full flaps and reduced the airspeed to 115 knots. At about this time, as he was retarding the power levers, the right engine flamed out. The pilot reported that he promptly sensed the engine failure and checked the engine instruments while re-opening both power levers. He noted both torque and fuel flow indication s for the right engine were zero. He briefly considered retracting the landing gear and flaps but decided to do neither. Left engine power was increased initially to the maximum available of 940°C ITT (Inter-turbine temperature) and then adjusted to the normal maximum limit of 923°C ITT. The right propeller was feathered. During this period the aircraft banked to the right and turned away from the runway. Its airspeed had reduced and the rate of descent increased. The turn had been opposed but the pilot found that the application of full left rudder and aileron would not enable him to maintain runway heading, although the airspeed was above the minimum control airspeed of 94 knots, specified in the aircraft flight manual. It was evident to the pilot that the aircraft would land short of the aerodrome, amongst trees to the right of the runway approach path. He therefore abandoned his efforts to regain the normal approach path and allowed the aircraft to turn further to the right, towards a large, clear paddock. Just before touchdown, he observed a power pole on his selected landing path and he again turned further right to avoid it. During this turn the right wing tip struck the ground. The nosegear then impacted heavily and collapsed . The aircraft slid and bounced across the ground for 188 metres before coming to rest. Fuel from ruptured line s ignite d under the left engine , but the fire was slow to develop and the occupants were able to make an orderly evacuation . By the time the fire brigade arrived from Esperance township, the fire had spread and most of the aircraft was consumed.
Probable cause:
The right engine had flamed out because of fuel starvation, when a spur gear in the fuel control drive train failed. Five teeth of the spur gear had broken off and the remaining teeth were badly worn. The failures and abnormal wear were due to looseness of the torque sensor housing, in which the spur gear was mounted, allowing the gear to move out of its correct alignment. The housing had probably loosened because of vibration, as its natural frequency was close to some frequencies generated by the engine during normal operation. The following contributing factors were reported:
- The natural frequency of the torque sensor housings in the engines fitted to VH-SWO were susceptible to vibration frequencies generated by the engines during normal operation,
- Vibration loosened the torque sensor housing on the right engine, which in turn led to misalignment of a spur gear in the fuel drive train, failure of the gear and fuel starvation
of the engine,
- The engine failed when the aircraft was being operated in a landing configuration which precluded a successful continuation of the landing approach,
- The landing procedure used by the pilot was in accordance with the operator's Company Operations Manual, which did not appreciate the poor performance and handing' difficulties of the Swearingen SA226TC in the event of an engine failure in the landing configuration.

Circumstances:
The aircraft was engaged in a scheduled service, designated Flight DR 4210, from Sydney to Temora and Condobolin, within the State of New South Wales. The scheduled departure time was 1845 hours. At 1844 hours the pilot of VH-AAV contacted Sydney Airport Clearance Delivery by radio and requested his airways clearance. The airways clearance issued was a Standard Instrument Departure (SID), titled '25 Katoomba Two'. That SID specified that radar headings would be assigned after take-off from Runway 25. The pilot correctly acknowledged the airways clearance. At 1848 hours the pilot contacted Sydney Ground Control and requested clearance to· taxi. This was granted and the aircraft was taxied to the holding point for Runway 25. The pilot reported to Sydney Aerodrome Control at 1858 hours that he was ready for take-off. Due to other traffic. the aircraft was not cleared to line up until 1906 hours. VH-AAV then entered Runway 25 and stopped about 50 metres from the threshold. At 1907 hours VH-AAV was cleared to 'maintain runway heading, maintain 3000 (feet), clear for take-off. This was correctly acknowledged and VH-AAV commenced takeoff. The aircraft became airborne and crossed the intersection with Runway 16/34, at a height of about 100 feet above ground level (AGL) at 1908:19 hours. The landing gear was retracted. Observers then noted the aircraft level off at about 150 feet AGL and commence a shallow banked turn to the left. As this was contrary to the departure instructions, Aerodrome Control was about to query the pilot when, at 1908:33 hours. he advised: ' ... we've lost er, the left engine. Request landing, ah, landing on runway three four immediately please.' This was acknowledged and Aerodrome Control cleared VH-AAV for a visual approach to a left base for Runway 34. During these transmissions, VH-AAV continued its left turn through approximately 90 degrees, onto a southerly heading. It had maintained a height of about 150 feet AGL and the left propeller was probably in the process of feathering. At 1908:44 hours, Aerodrome Control queried' ... do you have the seven two seven in sight on short final.' At 1908:49 hours, the pilot of VH-AAV replied, 'Affirmative'. The other aircraft referred to by Aerodrome Control was an Ansett Airlines of Australia Boeing 727, VH-RMO, which was on approach for Runway 34. Shortly after passing over the shore of Botany Bay, VH-AAV entered a steady descent and then levelled off just above the water. The left turn was continued and the aircraft converged towards the western side of the sea wall enclosing the extension of Runway 16/34. At 1908:50 hours, Aerodrome Control asked,' ... will your approach and landing be normal.' The reply, eight seconds later, was 'Alpha Alpha Victor negative'. At 1909:08 hours, Aerodrome Control activated the crash alarm system. In addition, VH-RMO was directed' ... go around, correction, st ... stay on the runway and expedite. We have a landing, er, right behind you ... one engine out.' The initial direction was made prior to visually assessing the Boeing ?27's situation, but when, during the transmission, it was noted that the aircraft was on the ground and well established in its landing roll sequence, the 'expedite' instruction was substituted. At 1909:20 hours, Aerodrome Control cleared VH-AAV to land. This was not acknowledged. The final segment of the flight was at an extremely low altitude and in a nose-high attitude. The right propeller, on at least one occasion, probably contacted the water and the tail either furrowed the water or induced a wake. VH-AAV struck the sea wall in a nose-up attitude, banking to the left and skidding to the right. The left wing of the aircraft disintegrated. The resultant fuel spillage ignited and a 'fire ball' explosion occurred. The right engine and the outboard section or the right wing both separated and were thrown across the ground adjacent to the runway. The remainder of the aircraft bounced over the sea wall, landed inverted on a taxiway and slid backwards. The accident occurred in daylight at 1909:22 hours. The aircraft was totally destroyed by impact forces and a post crash fire and all 13 occupants were killed.
Probable cause:
The cause of the accident has not been determined, but the most likely explanation is that the aircraft was operated in a reduced power configuration which, under the prevailing conditions, rendered its single-engine performance critical in respect to aircraft handling. The following findings were reported:
- At a height of about 100 feet AGL the left engine failed, probably due to the ingestion of water-contaminated fuel,
- The source of water contamination of the left fuel system of VH-AAV was not established but elemental analyses indicated the water had been present in the fuel system for some time,
- It could
not be determined where the water in the left fuel system of VH-AAV had accumulated or by what means it traveled to the left engine,
- It was not established whether or not the pilot had carried out a fuel drain check prior to the accident flight,
- At the time of engine failure, a high cockpit workload situation existed.
Final Report:
