What happened
On 05 August 2012, a Powerchute Kestrel microlight, registration G-MWFI, performed a series of low-altitude fly-bys over a vintage farm equipment rally near Dunmore, Co. Galway. The pilot had taken off from a nearby field to avoid the crowds at the rally site. During the maneuvers, the pilot observed a helicopter operating in the vicinity and focused on monitoring its flight path to maintain separation. While maneuvering around the edge of the rally field, the aircraft struck low-voltage electricity power lines. The impact caused the aircraft to hit the ground, resulting in minor injuries to the pilot and minor damage to the aircraft. The strike to the 220 V wires caused a temporary blackout for local residents.
The investigation
The AAIU examined the accident site and the aircraft. The investigation found that the power lines were approximately 10 metres above the ground at their lowest point. The aircraft's engine, canopy, and control lines were found to be in functional condition, though evidence of the wire strike was present on the airframe and the left wheel trans-axle was bent due to the ground impact.
Regarding the legal status of the flight, the investigation established that the aircraft had been de-registered in the United Kingdom in 2011 and lacked a valid Permit to Fly in Ireland. Additionally, the pilot was operating without a valid pilot licence.
Findings
- The pilot's attention was diverted by the need to monitor the flight path of an approaching helicopter.
- The aircraft was flying at a low altitude in close proximity to an assembly of people, which was a violation of the Rules of the Air.
- The aircraft was unregistered and the pilot was unlicensed.
