Circumstances:
During the takeoff roll at Seoul-Gimpo Airport, the left engine lost power and severe vibrations were encountered. The captain decided to abandon the takeoff and initiated an emergency braking procedure. Unable to stop within the remaining distance, the aircraft overran, lost its undercarriage, cartwheeled and came to rest, bursting into flames. All 48 occupants were evacuated, among them 21 were injured. The aircraft was totally destroyed.
Probable cause:
It was determined that the loss of power on the left engine was the consequence of ice that detached from the left upper wing and went into the engine. This caused the high pressure compressor to stall, followed by vibrations and a loss of directional control.
The following contributing factors were reported:
- Poor flight preparation on part of the flying crew,
- The aircraft has not been properly deiced prior to takeoff.

It eventually came to rest upside down in one meter deep water. A pilot was killed while all 11 other occupants were injured.

Circumstances:
Following an uneventful flight from Perm, the crew started the descent to Sovetskiy Airport and was informed about the weather conditions at destination with ceiling down to 80 meters and an horizontal visibility estimated to 2 kilometers, which was below minimums. Despite this situation, the crew decided to continue the approach and deliberately passed below the minimum descent altitude probably to establish a visual contact with the ground. On short final, the aircraft struck tree tops (25 meters high), banked right and crashed in a wooded area located 700 meters short of runway 30, about 250 meters to the right of its extended centerline, bursting into flames. Eight passengers were rescued while 32 other occupants were killed.
Probable cause:
It was determined that the accident was the consequence of a wrong approach configuration of the flying crew who decided to continue the approach in below weather minimums and passed the MDA until the aircraft contacted trees and crashed.
The following contributing factors were reported:
- Poor approach planning,
- Unsatisfactory crew interactions,
- Poor distribution of tasks among the flight crew,
- Violation of minimums,
- The crew decided to continue the approach after passing the MDA,
- The crew failed to initiate a go-around procedure.

Circumstances:
De Havilland DHC-6, N707PV (Aloha Islandair flight 1712), collided with mountainous/hilly terrain near Halawa Bay, HI, while en route on a scheduled passenger flight at night from Maui to Molokai, HI. Impact occurred at an elevation of about 500 feet, shortly after the aircraft had descended over water, then crossed the shoreline. There was evidence that the captain had made a navigational error and mistakenly believed that he was circumnavigating the northern portion of Molokai Island. The aircraft crashed while on a heading that was parallel with the island's northern shoreline. Low clouds obscured the mountain tops in the area of the accident. There was also evidence of inadequate supervision of personnel, training and operations by Aloha Islandair management and insufficient oversight of Aloha Islandair by the FAA during a period of Aloha Islandair's rapid operational expansion. All 20 occupants were killed.
Probable cause:
The airplane's controlled flight into terrain as a result of the decision of the captain to continue flight under visual flight rules at night into instrument meteorological conditions (IMC), which obscured rising mountainous terrain. Contributing to the accident was: the inadequate supervision of personnel, training, and operations by aloha islandair management and insufficient oversight of Aloha Islandair by the Federal Aviation Administration particularly during a period of rapid operational expansion.
