# NTSB ANC05CA131: Maule M-5-210C, N51623, Fairbanks, AK, August 29, 2005 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: August 28, 2005, 16:00 local (Aug 29, 2005, 00:00 UTC) - Place: Fairbanks, AK - Coordinates: 64.033332, -148.171661 - Nearby events: https://openairdocs.org/map.md?lat=64.0333&lon=-148.1717&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report December 20, 2005 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - Parties: Fairbanks FSDO - NTSB case key (mKey): 62345 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC05CA131 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/62345/pdf - Page: https://openairdocs.org/ntsb/ANC05CA131 ## Probable cause The pilot's inadequate compensation for wind conditions during the landing roll, which resulted in a loss of control and subsequent collapse of the main landing gear. Factors associated with the accident were a crosswind, and a steep drop-off. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - weather condition - crosswind (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - Main gear collapsed, landing - roll - terrain condition - drop-off/descending embankment (contributing factor) ## Analysis The commercial pilot was landing on a ridgeline which required a correction for a right crosswind. He stated that during the landing roll a gust of wind lifted the right wing, and he applied full right aileron in conjunction with heavy braking. He said that the wind subsequently pushed the airplane to the left, down a steep slope on the north side of the site, and both main landing gear collapsed. The airplane sustained structural damage to the fuselage and both wings. The pilot noted that there were no preaccident mechanical anomalies with the airplane. ## Factual narrative On August 28, 2005, about 1600 Alaska daylight time, a tundra tire-equipped Maule M-5-210C airplane, N51623, sustained structural damage while landing at an off airport site, located about 50 miles south of Fairbanks, Alaska. The airplane was being operated as a visual flight rules (VFR) personal flight under Title 14, CFR Part 91, when the accident occurred. The private pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed. The flight originated at the Fairbanks International Airport, Fairbanks, about 1500, and no flight plan was filed. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on August 29, the pilot reported that he was landing to the east on a ridgeline which required a correction for a right crosswind from the southeast. He stated that during the landing roll a gust of wind lifted the right wing, and he applied full right aileron in conjunction with heavy braking. He said that the wind subsequently pushed the airplane to the left, down a steep slope on the north side of the site, and both main landing gear collapsed. The airplane sustained structural damage to the fuselage and both wings. The pilot noted that there were no preaccident mechanical anomalies with the airplane. ## Aircraft - Registration: [N51623](https://openairdocs.org/deregistered/N51623-2020-10-31), registration cancelled 2020-10-31, S/N 6041C, built 1974 (OpenAirDocs) - Reported make and model: Maule M-5-210C - Registry model: [Maule M-5-210C](https://openairdocs.org/model/maule-m-5-210c) (registry code 5460134) (OpenAirDocs) - Registry engine: [Continental IO-360 series](https://openairdocs.org/engine/continental-io-360-series) (registry code 17025, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 6041C - Airframe hours: 1944.7 - Engines: Continental IO-360-DB33D 210 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Timothy L.

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.
