What happened
On 6 October 2019, a Rollason D.62B Condor, registration EI-BDX, was conducting a flight in the Duncormick area of Co. Wexford. The aircraft, operated by a private group, was being flown by a pilot accompanied by an instructor. Following a normal takeoff from Taghmon Airfield, the aircraft climbed to at least 3,000 feet.
During the flight, witnesses observed the aircraft performing several consecutive rolls. Later, observers reported seeing the aircraft execute three loops. As the aircraft descended from the top of the third loop, witnesses heard loud cracking or banging noises. Immediately following these sounds, portions of the aircraft separated, and the plane began a downward spiral. The impact resulted in 2 fatalities and the total destruction of the aircraft.
The investigation
Investigators examined the wreckage spread across several agricultural fields, noting that the engine, propeller, instrument panel, and the right-hand wing were recovered, while only the root of the left-hand wing remained. The two occupants were found approximately 50 meters from the main wreckage.
Evidence from witnesses suggested that the aircraft was performing maneuvers just prior to the structural failure. The investigation also reviewed the aircraft's operational rules and flight permit. While the flight manual allows for spins, the aircraft's specific flight permit stated that aerobatic maneuvers were not permitted. Additionally, the investigation looked into the aircraft's structural limits, which specified a maximum load factor of 3.0g for normal flight.
Findings
- The aircraft was performing aerobatic maneuvers, including loops and rolls, which were inconsistent with the restrictions on its flight permit.
- Witnesses reported hearing loud structural noises and seeing parts separate from the aircraft during a descent from a loop.
- The aircraft was a wood and fabric construction, which may have been susceptible to the stresses of the maneuvers performed.
