# NTSB ANC04LA036: Stinson 108-2, N97124, Levelock, AK, March 23, 2004 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: March 23, 2004, 12:00 local (16:00 UTC) - Place: Levelock, AK - Coordinates: 59.099998, -156.899993 - Nearby events: https://openairdocs.org/map.md?lat=59.1000&lon=-156.9000&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report September 29, 2004 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - Parties: FAA-AL-ANC FSDO 03 - NTSB case key (mKey): 58943 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC04LA036 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/58943/pdf - Page: https://openairdocs.org/ntsb/ANC04LA036 ## Probable cause The pilot's selection of unsuitable terrain for landing, which resulted in an overrun. Factors contributing to the accident were the pilot's inadequate weather evaluation, a tailwind, and a slippery, ice-covered landing surface. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - weather evaluation - inadequate, pilot in command (contributing factor) - weather condition - tailwind (contributing factor) - terrain condition - icy (contributing factor) - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (cause) - On ground/water encounter with terrain/water, landing - roll - terrain condition - muskeg ## Analysis The private certificated pilot was landing a wheel-equipped airplane on a frozen lake that was about 1,000 feet long. The landing was the second landing of the day at the lake. The pilot said he was landing toward the north, and after touchdown he applied the brakes. The airplane failed to stop, and slid off the frozen surface into an area of muskeg. The pilot said the airplane received damage to the propeller and the main landing gear attach points at the fuselage. He indicated that after the accident, he noticed a 5 to 10 knot wind from the south, and the ice surface of the lake was slippery due to slight melting. The pilot noted that there were no preaccident mechanical problems with the airplane. ## Factual narrative On March 23, 2004, about 1200 Alaska standard time, a wheel-equipped Stinson 108-2 airplane, N97124, sustained substantial damage when it overran the intended landing area on a frozen lake and encountered rough terrain, about 2 miles south of Levelock, Alaska. The airplane was being operated as a visual flight rules (VFR) cross country personal flight under Title 14, CFR Part 91, when the accident occurred. The airplane was operated by the pilot. The private certificated pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed. The flight originated at the Naknek Airport, Naknek, Alaska, about 1118. No flight plan was filed, nor was one required. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on March 23, the pilot reported that the landing was the second of the day on a frozen lake that was about 1,000 feet long. He said he was landing toward the north, and after touchdown he applied the brakes. The airplane failed to stop, and slid off the frozen surface into an area of muskeg. The pilot said the airplane received damage to the propeller and the main landing gear attach points at the fuselage. He indicated that after the accident, he noticed a 5 to 10 knot wind from the south, and the ice surface of the lake was slippery due to slight melting. The pilot indicated there were no preaccident mechanical problems with the airplane. ## Aircraft - Registration: [N97124](https://openairdocs.org/aircraft/N97124), registered now, S/N 108-1124 (OpenAirDocs) - Reported make and model: Stinson 108-2 - Registry model: [Stinson 108-2](https://openairdocs.org/model/stinson-108-2) (registry code 9230406) (OpenAirDocs) - Registry engine: [Franklin 6A4165 series](https://openairdocs.org/engine/franklin-6a4165-series) (registry code 27025, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 108-1124 - Engines: Franklin 6A4-165-B3 165 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Bruce C.

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.
