What happened
On 6 October 2019, a Rollason D.62B Condor, registration EI-BDX, departed ILAS Field near Taghmon, Co. Wexford, for a local flight. The aircraft was occupied by two individuals: the pilot and an instructor. The flight was intended for the pilot to perform maneuvers as part of a license revalidation process.
During the flight, witnesses in the Duncormick area observed the aircraft performing various maneuvers, including circling, looping, and spinning. At approximately 16:40 hrs, onlookers reported hearing a loud noise followed by the aircraft breaking apart in the sky. The wreckage was distributed over a wide area, and the impact resulted in 2 fatalities. There was no fire at the scene, but the aircraft was completely destroyed.
The investigation
The AAIU examined the wreckage and interviewed 18 witnesses. Evidence indicated that the flight was planned to include spinning maneuvers. Prior to takeoff, the instructor had removed loose items from the aircraft's rear luggage shelf, a necessary precaution for spinning in this aircraft type.
Investigators also reviewed the aircraft's maintenance history and flight logs. The aircraft was found to be in good condition, with no evidence of structural deterioration such as moisture ingress or glue joint failure. The investigation also analyzed the aircraft's center of gravity and fuel levels, concluding that the aircraft was likely within its allowable operating limits at the time of the accident.
Findings
- The aircraft was performing maneuvers that included spinning, which is permitted under its flight manual.
- The aircraft's maintenance records showed no signs of age-related structural decay.
- The in-flight breakup likely began when the left wing spar failed due to positive g-loading.
- Following the wing failure, debris from the wing struck the empennage, causing the rudder to separate and bend.
- The resulting loss of control led to a rapid rotation and the subsequent disintegration of the cockpit and harness attachment points.
- The intensity of the breakup rendered the accident non-survivable.
