Accident Details
On an unspecified date, a single-engine airplane departed from Igiugig Airstrip under poor weather conditions characterized by low clouds and limited visibility due to snowfall. During the initial climb, the pilot lost control of the aircraft. The airplane subsequently crashed into the slope of a mountain. The impact totally destroyed the aircraft, and all four occupants were killed.
Investigation and Probable Cause
The official investigation determined the probable cause of the accident to be an uncontrolled descent after the pilot continued VFR flight into adverse weather conditions. Contributing factors reported included improper in-flight decisions on the part of the pilot and the presence of snow, which likely reduced visibility and affected aircraft performance.
The investigation did not specify the aircraft model, registration, or other details such as time of day or ATC involvement.
