Accident Overview
On June 29, 2019, at approximately 1850 mountain standard time, a Piper PA-28R-200, registration N786N, sustained substantial damage during a landing accident at Chandler Municipal Airport (CHD) in Chandler, Arizona. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot and a passenger were not injured.
Pilot Account
According to the pilot, who was seated in the right seat, his son, who was not a pilot, occupied the left seat. The pilot reported that he often alternated seats on different flights for proficiency. The flight originated from Stellar Airpark (P19) to CHD for landing practice. The first touch-and-go landing on runway 22R was uneventful. The pilot stated that the second landing was normal, but during the rollout, the airplane began to drift left and the left wing dropped. The pilot applied full right rudder, which caused the airplane to yaw to the right. He applied brakes as the airplane moved right, but seconds later, the left main landing gear collapsed, and the airplane came to a stop on the runway with the left wing and left stabilator contacting the runway. The nose landing gear and right main landing gear remained extended and locked, but the left main landing gear appeared mostly retracted into its wheel well.
Weather
The 1856 CHD special weather observation recorded wind from 260° at 12 knots with gusts to 22 knots.
Post-Accident Examination
Examination of the main landing gear system revealed that the landing gear lever was in the deployed position. The left landing gear was partially extended, with the upper side brace link exhibiting a smooth bend. The hydraulic actuator cylinder was extended and remained attached to the retraction bracket. The truss support bracket was displaced from its normal position on the wing spar, with its bolts and screws bent or broken. The left tire displayed radial scuff marks on the outboard sidewall. The airframe sustained substantial damage to the left wing, stabilator, and empennage.
