The pilot and passenger of a Yakovlev Yak-52 aircraft, registered VH-PAE, were conducting a private aerobatic flight from Southport Airport, Queensland. During the flight, while near South Stradbroke Island, the aircraft collided with water. The occupants were fatally injured and the aircraft was destroyed.
Contributing factors:
While conducting an aerobatic flight, which included low-level manoeuvres, for reasons undetermined, the aircraft collided with the water at high speed.
Other factors that increased risk:
- The pilot was not trained or endorsed for low-level aerobatics, but conducted them on the accident flight and previous flights. This behaviour increased the risk of an accident from either a mishandled manoeuvre or adverse physiological effects.
- The pilot had previously performed unsafe acts that were witnessed by people from the aviation industry. While the pilot did receive previous warnings, there were other opportunities and means for people to formally communicate and escalate their concerns that were not used.
- A pre-existing fatigue crack was found in the elevator bellcrank, which had the potential to fail in-flight and lead to a loss of control.
- There was no formal mechanism for the state of design to provide airworthiness information for Yak-52 aircraft that had reached the end of their prescribed airframe life. This resulted in updated information regarding the elevator bellcrank inspection interval and design not being known or included in local maintenance schedules.
- The Australian Warbirds Association Limited did not consider Yak-52 aircraft to have an airframe life, and therefore, they were assigned a permit index of zero, which allowed flight over populous areas. However, there was information available from Yakovlev via the United Kingdom Civil Aviation Authority that detailed airframe life limits.
