FACTORS INCLUDE THE PILOT'S FATIGUE, AND TREES NEAR THE SIDE OF THE RUNWAY. ## 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 - directional control - not maintained, pilot in command (cause) - fatigue, pilot in command (contributing factor) - On ground/water collision with object, landing - roll - object - tree(s) (contributing factor) ## Analysis WHILE ATTEMPTING A LANDING, THE 'EXTREMELY TIRED' PILOT LOST CONTROL OF THE TAILWHEEL EQUIPPED AIRCRAFT, AND DEPARTED THE SIDE OF THE RUNWAY. AFTER GOING OFF THE SIDE OF THE RUNWAY, THE AIRCRAFT IMPACTED TREES, AND SUSTAINED SUBSTANTIAL DAMAGE. ## Factual narrative On July 7, 1994, at 1900 Pacific daylight time (PDT), a tailwheel equipped Stinson 108-3, N6276M, veered off the runway and collided with trees while landing at Ione Municipal Airport, Ione, Washington. The private pilot, who was the sole occupant of the aircraft, was not injured, but the aircraft sustained substantial damage. Visual meteorological conditions prevailed at the time of the accident, and no flight plan was filed. There was no report of an ELT activation. According to the pilot, she experienced a considerable amount of turbulence during the flight, and was "extremely tired" upon arrival at Ione. While attempting to land at Ione Municipal Airport, the aircraft veered slightly to the left of the centerline, the pilot over-corrected to the right, and ran off the runway. The aircraft then hit a tree, causing substantial damage to the prop and right wing. ## Aircraft - Registration: [N6276M](https://openairdocs.org/deregistered/N6276M-2013-08-20), registration cancelled 2013-08-20, S/N 108-4276, built 1948 (OpenAirDocs) - Reported make and model: STINSON 108-3 - Registry model: [Stinson 108-3](https://openairdocs.org/model/stinson-108-3) (registry code 9230408) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 108-4176 - Engines: CONTINENTAL O-470 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Look, Shirley A. - Airworthiness certificate: Standard, Normal - Departed: 75S, SKAGIT/BAYVIEW, WA - Airport: S23, Ione Municipal, runway 15, 4,100 × 45 ft, asphalt ## Flight crew As NTSB recorded them.
