The unfavorable wind condition was a related factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, taxi - from landing - weather condition - unfavorable wind (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - aircraft control - not maintained, pilot in command (cause) - On ground/water encounter with terrain/water, taxi - from landing - airport facilities,runway/landing area condition - drop-off/descending embankment - Gear collapsed, taxi - from landing - landing gear,main gear - overload ## Analysis The pilot stated that after landing and while making a wide right turn to back taxi, a gust of wind pushed the airplane off to the left side of the runway. Inspection of the airplane revealed that the left main gear brace support bracket and pivot bolt failed due to overload conditions. ## Factual narrative On May 11, 1997, at 1345 central daylight time (cdt), a Piper PA- 24-250, N7729P, registered to KCB Aviation, Inc., of West Des Moines, Iowa, was substantially damaged following a loss of control during the landing roll on runway 05 on a private sod airstrip near Correctionville, Iowa. The private pilot and passenger reported no injuries. The personal 14 CFR Part 91 flight was operating in visual meteorological conditions. No flight plan was filed. The flight originated from Ankeny, Iowa, exact time unknown. The pilot did not submit the required National Transportation Safety Board's form 6120.1/2 under Title 49, Part 830.15. In a written statement to the Federal Aviation Administration (FAA)the pilot said that after landing he turned the airplane to the right to back taxi when an extremely strong gust of wind began sliding the airplane to the left side of the runway. The FAA Inspector who examined the airplane found the left main gear brace support bracket and pivot bolt failed due to overload conditions. ## Aircraft - Registration: [N7729P](https://openairdocs.org/aircraft/N7729P), registered now, S/N 24-2943, built 1961 (OpenAirDocs) - Reported make and model: Piper PA-24-250 - Registry model: [Piper PA-24-250](https://openairdocs.org/model/piper-pa-24-250) (registry code 7102404) (OpenAirDocs) - Registry engine: [Lycoming 0-540 series](https://openairdocs.org/engine/lycoming-0-540-series) (registry code 41532, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 24-2943 - Engines: Lycoming O-540-A1A5 250 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Kcb Aviation, Inc. - Airworthiness certificate: Standard, Normal - Departed: IKV, ANKENY, IA - Airport: Private Airstrip, runway 5, grass/turf ## Flight crew As NTSB recorded them.
