While attempting to get the airplane realigned with the runway, he overcorrected. In his attempt to compensate for the overcorrection, he overcorrected in the opposite direction. This sequence of events resulted in a series of overcorrections followed by a loss of directional control, and the airplane departed the side of the runway. After departing the runway, the airplane made an abrupt turn of about 90 degrees, the left main landing gear collapsed, and the left wing impacted the terrain, which resulted in structural damage to the wing. The pilot reported that there was no mechanical malfunction during the accident. ## Factual narrative During the landing roll, the student pilot, who was performing a series of touch-and-go landings, allowed the airplane to veer slightly to one side. While attempting to get the airplane realigned with the runway, he overcorrected. In his attempt to compensate for the overcorrection, he overcorrected in the opposite direction. This sequence of events resulted in a series of overcorrections, followed by a loss of directional control, which was followed by the airplane departing the side of the runway. After departing the runway, the airplane made an abrupt turn of about 90 degrees, whereupon the left main landing gear collapsed and the left wing impacted the terrain. The impact with the terrain resulted in structural damage to the wing. The pilot reported that there was no mechanical malfunction associated with the accident. ## Aircraft - Registration: [N55634](https://openairdocs.org/deregistered/N55634-2017-03-07), registration cancelled 2017-03-07, S/N 28-7325448, built 1973 (OpenAirDocs) - Reported make and model: PIPER PA-28-140 - Registry model: [Piper PA-28-140](https://openairdocs.org/model/piper-pa-28-140) (registry code 7102802) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 28-7325448 - Engines: LYCOMING O-320 SERIES 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Executive Pilots, Inc - Registered owner: Blair Joel M - Airworthiness certificate: Standard, Normal - Departed: North Las Vegas, NV - Destination: 0L7, Jean, NV - Airport: 0L7, Jean Airport, runway 02R, 3,700 × 60 ft, asphalt ## Flight crew As NTSB recorded them.
