Accident Details
The pilot was conducting the first flight of the airplane after an annual inspection had been performed. The start-up, taxi, and run-up all appeared to be normal, so the pilot elected to depart. During the takeoff roll, at an airspeed of about 70 knots, the airplane yawed left, departed the runway pavement, and struck a windsock pole.
Post-Accident Examination
Following the accident, a mechanic examined the brake systems of the airplane. The examination noted that the left main gear parking brake was improperly connected, and the left main gear brake check valve was inoperative. This resulted in constant pressure being placed to the left brake calipers.
The findings indicate that the left braking system was compromised, leading to unequal braking forces during the takeoff roll. The exact sequence of events and the pilot's actions during the incident were not further detailed in the investigation reports.
No other mechanical anomalies were reported in the examination of the aircraft's systems. The aircraft sustained damage from the collision with the windsock pole, and the runway departure resulted in additional ground contact damage. The investigation did not specify the extent of damage or any injuries.
