NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.
Puntilla Lake, AK
IMMEDIATELY AFTER TAKEOFF, THE PILOT BECAME UNSURE OF CLEARING THE MOUNTAINOUS TERRAIN. A 180 DEG TURN WAS INITIATED DURING WHICH THE PILOT ENCOUNTERED A STRONG DOWNDRAFT. PASSENGERS AND WITNESSES STATED THAT THE AIRPLANE MAINTAINED AN UNUSUAL NOSE-HIGH ATTITUDE AND LOW AIRSPEED FROM LIFT-OFF TO JUST BEFORE IMPACT. THE PILOT HAD TAKEN OFF FROM A ROUGH AREA ON THE FROZEN LAKE, DIFFERENT FROM THE USUAL TAKEOFF AREA.
THE PILOT'S FAILURE TO OBTAIN AN ADEQUATE AIRSPEED, THE TURN TO REVERSE COURSE MANEUVER PERFORMED AT THE REDUCED AIRSPEED AND POOR PREFLIGHT PLANNING. CONTRIBUTING TO THE ACCIDENT WERE THE MOUNTAINOUS TERRAIN AND THE DOWNDRAFT CONDITIONS.
