Circumstances:
During initial climb, at a height of about 60 metres and at a speed of 317 km/h, the left engine failed. The copilot counteracted the left bank and five seconds later, the flight engineer informed the crew that the right engine also failed. The captain took over control and the aircraft climbed to the height of 197 metres when the speed dropped to 290 km/h. The captain elected to make an emergency landing but was forced to make a sharp turn to the right to avoid a building. The aircraft rolled to the right to an angle of 37° and adopted a rate of descent of 1,960 feet per minute before crashing in an open field located 3,850 metres from the airport. The aircraft disintegrated on impact. Thirty occupants were rescued while 52 others, among them two crew members, were killed.
Probable cause:
It was determined that the left engine failed during initial climb following the disintegration of the 2nd and 3rd stage of the compressor. Investigations revealed that the maintenance was non compliant and that 38 screws were missing on the main compressor, a violation that was not repaired during the last maintenance inspection conducted 30 flying hours prior to the accident. Following a lack of crew coordination but also a faulty ergonomy of the flight deck, the flight engineer mistakenly shut down the right engine that was running properly.

Circumstances:
After takeoff at dawn on a foggy morning, the airplane collided with electrical transmission wires about one mile from the end of the runway, on an extended line about 50 degrees left of the extended runway centerline. The left wing tip fuel tank (left main) was partially severed from the airplane, breaching the tank. Additionally, the top of the vertical stabilizer and rudder were severed, and a portion of the windscreen was separated. A suggestion was made by the operator that the autopilot trim may have been improperly set, precipitating a nose pitch down upon engagement of the autopilot during the climb. The airplane continued to fly for about 20 minutes, then impacted in a steep right wing down attitude into a densely wooded area that was surrounded by open terrain. The ensuing fire precluded any determination of engine malfunction, systems' discrepancies, or wire strike damage to the left propeller. No determination of pilot incapacitation was possible because of the post impact fire. Based upon the ground witness statement, the left engine was probably inoperative following the wire strike. The impact attitude was inconsistent with a decreasing speed loss of control with the left engine inoperative. However, the flight control trim settings, left main fuel tank selected, and throttle quadrant settings all may have been indicative of pilot incapacitation that precluded proper emergency procedure response. Additionally, the airplane impacted into a densely wooded area surrounded by flatter terrain absent of tall obstacles.
Probable cause:
The failure of the pilot to maintain the proper climb rate and direction of flight following takeoff, resulting in a collision with obstacles. The reason for the loss of control and subsequent unusual attitude ground impact was not determined.

Circumstances:
The Eagle Air Services Piper PA-31-325 Navajo, C-GOLM, departed runway 34 at Wollaston Lake, Saskatchewan, at 2325 central standard time (CST), on a medical evacuation (MEDEVAC) flight to La Ronge. The flight was arranged by the Wollaston nursing station to transport a patient to a hospital in La Ronge. The patient was accompanied on the flight by her mother and a nurse from the nursing station. The aircraft was observed to climb at an unusually shallow angle after take-off, and, when efforts by company personnel to reach the pilot by radio were unsuccessful, a ground search was commenced. The aircraft was found about five minutes after the accident, located on the ice- and snow-covered surface of Wollaston Lake, about 0.75 nautical miles (nm) from the departure end of the runway, and about 1.3 nm from the point of commencement of the take-off roll. The pilot and the patient suffered serious injuries. The other two occupants sustained minor injuries. The accident occurred during the hours of darkness at latitude 58°6.98'N, longitude 103°10.79'W, at an elevation of 1,300 feet above sea level (asl). The temperature was about -25°/C.
Probable cause:
After take-off, the left propeller was likely on its start locks, which, as the airspeed increased, allowed the propeller to overspeed. The pilot was unable to resolve the situation in time to prevent the aircraft from striking the surface of Wollaston Lake. Contributing to the severity of the patient's injuries were the inadequate restraint provided by the stretcher and its restraining strap, the lack of standards regarding stretchers used in aircraft, and the lack of standards as to the operation of MEDEVAC flights.

Circumstances:
The aircraft was the second to take off in a stream of six on a night flight from the Tangalooma Resort strip to Coolangatta aerodrome. Shortly after takeoff it struck the ground, nosed over and was consumed by a fuel-fed fire. The take-off run appeared normal but the initial climb was shallow according to the witnesses, some of whom were pilots waiting their turn to take off. At about 150 ft above ground level the aircraft entered a descent which continued until ground impact, 164 m beyond the departure end of the strip. The nose gear collapsed at impact but the aircraft remained upright and skidded along the ground on its main gear and front fuselage. It traversed a low sand dune, fell 10 ft to the beach and overturned. The aircraft came to rest 112 m beyond the first ground contact. All four passengers were able to evacuate the aircraft which had started to burn. The pilot was rescued by her passengers.
Probable cause:
The following factors were reported:
1. The takeoff direction was dark and had no visible horizon.
2. The elevator trim was not set for takeoff.
3. The elevator load on takeoff was high.
4. The pilot did not monitor the aircraft attitude after lift-off.
5. The flap was retracted in one movement, increasing the elevator load.
6. The pilot may have been affected by somatogravic illusion to the extent that she thought the climb attitude was adequate.

The aircraft was destroyed and all five occupants were killed.
Probable cause:
Loss of control while completing a turn to return to the airport because the crew failed to recognize the aircraft's limits. Lack of crew training and experience was a contributing factor.
