The defining event best describes what happened. - [Landing-landing roll: Landing gear collapse](https://openairdocs.org/ntsb-events/094) (defining event); cases with it: [Piper PA-24-250, 9 cases](https://openairdocs.org/ntsb-events/094/sequence.md?model=7102404), [All aircraft, 1,787 cases](https://openairdocs.org/ntsb-events/094/sequence.md) ## Analysis The pilot reported that shortly after touchdown, the right main landing gear collapsed, and the airplane veered off the runway. After exiting the paved runway, the left main and nose landing gear collapsed. The airplane received structural damage to the right wing. Examination of the landing gear system revealed that the left main landing gear actuator rod was separated, and that the fracture was consistent with overload; no other anomalies were found. Continuity was established throughout the landing gear system. The landing gear was extended manually and locked in the down position. The landing gear warning light functioned normally when tested. ## Factual narrative On January 11, 2008, about 1815 Pacific standard time, a Piper PA-24-250, N7988P, sustained substantial damage following a gear collapse on landing at the Placerville Airport, Placerville, California.
