# NTSB ANC95LA060: Piper PA-22, N8021D, Koliganek, AK, May 29, 1995 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 28, 1995, 18:30 local (May 29, 1995, 02:30 UTC) - Place: Koliganek, AK - Coordinates: 58.819385, -157.860595 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=58.8194&lon=-157.8606&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report November 30, 1995 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - NTSB case key (mKey): 2653 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC95LA060 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/2653/pdf - Page: https://openairdocs.org/ntsb/ANC95LA060 ## Probable cause THE PILOT'S FAILURE TO ATTAIN THE PROPER APPROACH AND LANDING SPEED, NOT MAINTAINING DIRECTIONAL CONTROL, AND HIS INADEQUATE REMEDIAL ACTION(S). A FACTOR IN THE ACCIDENT WAS THE LOOSE OBJECTS IN THE LANDING AREA. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - flare/touchdown - airspeed(vref) - not attained, pilot in command (cause) - terrain condition - loose objects (contributing factor) - directional control - not maintained, pilot in command (cause) - In flight collision with object, landing - aborted - terrain condition - high vegetation - remedial action - inadequate, pilot in command (cause) - Nose over, landing - aborted ## Analysis THE PILOT STATED HIS APPROACH AND LANDING SPEED WAS TOO FAST AND THE AIRPLANE BOUNCED UPON TOUCHDOWN. WHEN IT TOUCHED DOWN A SECOND TIME THE LEFT MAIN GEAR STRUCK A SMALL PILE OF SAND AND STICKS. TO REGAIN DIRECTIONAL CONTROL THE PILOT ADDED FULL POWER. HE STATED HE HAD INSUFFICIENT ROOM IN WHICH TO STOP THE AIRPLANE SO HE ATTEMPTED TO ACCELERATE AND CLIMB OUT. THE AIRPLANE'S MAIN GEAR STRUCK SOME BRUSH LOCATED 75 FEET PAST THE DEPARTURE END OF THE LANDING/TAKEOFF AREA. THE AIRPLANE NOSED OVER INTO THE MULCHATNA RIVER. ## Factual narrative On May 28, 1995, at 1830 Alaska daylight time, a wheel equipped Piper PA-22 airplane, N8021D, registered to and operated by the pilot, nosed over and crashed into the Mulchatna River, 18 miles southeast of Koliganek, Alaska. The personal flight, operating under 14 CFR Part 91, departed the accident site for a local flight. No flight plan was filed and visual meteorological conditions prevailed. The airplane was substantially damaged and the pilot, the sole occupant, was not injured. According to the pilot, he departed the sandbar to burn off fuel. Upon returning for landing, the approach and landing airspeed was "too hot." The airplane bounced and when it touched down the second time the left main landing gear struck a small pile of sand and sticks. The pilot stated he lost directional control and he added full power. He regained control of the airplane but was too fast to stop in the remaining landing area. He attempted to accelerate and climb out but was unable to clear the brush located past the departure end of the landing area. The main gear hit the brush and the airplane nosed over into the Mulchatna River. The pilot stated, the takeoff area on the sandbar was 650 feet long and 50 feet wide. The brush that the airplane struck was 75 feet beyond the end of the takeoff area. ## Aircraft - Registration: [N8021D](https://openairdocs.org/aircraft/N8021D), registered now, S/N 22-5546, built 1957 (OpenAirDocs) - Reported make and model: PIPER PA-22 - Registry model: [Piper PA-22-150](https://openairdocs.org/model/piper-pa-22-150) (registry code 7102210) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 22-5546 - Engines: LYCOMING O-320 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Kennerson, Roland S. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, August 15, 1994, 80 hours before ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
