A factor was a rock just off the edge of the runway surface. ## Analysis During a landing on a 30 foot wide private airstrip, the aircraft bounced back into the air after contacting the runway surface. While it was airborne, the pilot failed to maintain directional control to an extent that would ensure that the aircraft remained within the lateral boundaries of the runway surface during the second touchdown. When the aircraft touched down the second time, the left main gear was off the runway. Soon after the second touchdown, the left main wheel impacted a rock that was just off the left side of the runway surface. The collision with the rock resulted in the left main gear leg collapsing and the left wing impacted the terrain. ## Factual narrative On November 28, 1999, approximately 1345 Pacific standard time, a Piper PA-12, N7243V, experienced a gear collapse during the landing roll on a private airstrip near Goldendale, Washington. The private pilot and his passenger were not injured, but the aircraft, which was owned and operated by the pilot, sustained substantial damage. The 14 CFR Part 91 personal pleasure flight, which departed Pearson Airpark, Vancouver, Washington, about 75 minutes earlier, was being operated in visual meteorological conditions. No flight plan had been filed, and there was no report of an ELT activation. According to the pilot, when he touched down on the 30 foot wide runway, the aircraft bounced back into the air. Instead of initiating a go-around, the pilot tried to salvage the landing, and when the aircraft touched down a second time, the left gear was off the side of the runway. Soon after the second touchdown, the left gear impacted a rock just beyond the edge of the runway. As a result of impacting the rock, the left main gear leg collapsed and the left wing contacting the terrain. The pilot reported that there was no evidence of a malfunction in the flight control system, and that the aircraft touched down with one wheel off the runway because he had inadvertently allowed it to drift beyond the runway edge. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Gear collapsed, landing - roll - recovery from bounced landing - improper, pilot in command (cause) - directional control - not maintained, pilot in command - terrain condition - rock(s)/boulder(s) ## Aircraft - Registration: [N7243V](https://openairdocs.org/aircraft/N7243V), registered now, S/N 123238, built 1947 (OpenAirDocs) - Reported make and model: Piper PA-12 - Registry model: [Piper PA-12](https://openairdocs.org/model/piper-pa-12) (registry code 7101202) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 123238 - Airframe hours: 3184 - Engines: Lycoming O-320-A2B 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Dwayne A.
