Accident Summary
An aircraft departing from Lindbergh Field experienced a stall shortly after takeoff. According to the official investigation, the pilot initiated a sharp turn while climbing at a height of 50 feet. The aircraft stalled and subsequently crashed in flames. The accident resulted in one passenger suffering serious injuries, while the other three occupants were killed.
Investigation Findings
Investigators determined that the engine failed after rotation. The failure was attributed to a cracked shroud on the third stage stator assembly, which was caused by fatigue fracture. Additionally, the pilot had used the minimum runway length for takeoff and employed a minimum takeoff speed. These factors were part of the probable cause identified in the official findings.
