Flight MF1285
Departure
Gander International Airport, Gander, Canada
Destination
Fort Campbell Army Airfield, Kentucky, USA
Causation Breakdown
Recurrence Likelihood Today
Low
Cold weather takeoff procedures now require mandatory anti-icing holdover time calculations and verification of clean wing surfaces. Weight and balance auditing has been strengthened for charter operations.
Summary
Arrow Air 1285 was carrying 248 U.S. Army soldiers home from Sinai peacekeeping duty when it crashed just after takeoff from Gander, Newfoundland. The aircraft struck a hillside after failing to climb. Ice contamination and excess weight were the official findings. It remains Canada's deadliest aviation disaster. The crash occurred during the Christmas season, deepening the national mourning.
Cause & Investigation
Determined cause
Wing ice contamination causing takeoff stall
The aircraft failed to climb after liftoff and stalled at low altitude. Investigators concluded that ice contamination on the wing surfaces significantly reduced lift, while the aircraft was also above its certified maximum takeoff weight. The combination prevented climb. Some Canadian investigators contended a fire preceded the crash, but the majority finding cited ice and excess weight.
Investigation body
Canadian Aviation Safety Board (CASB).

Improvement implemented
De-icing and anti-icing procedures for military charter operations were significantly strengthened.
Improvement implemented
Weight and balance verification requirements for charter flights were tightened.
Improvement implemented
Cold weather ground operations inspections before each takeoff became mandatory in Canada.
Improvement implemented
Arrow Air's operating certificate was subsequently revoked by Transport Canada.
