Confidence Rating: Accident investigation report completed and information captured
The Comco Ikarus C42B aircraft, with the pilot and one passenger on board, was en route from Sligo Airport (EISG) to Belmullet Aerodrome, Co. Mayo (EIBT). When the aircraft was overhead Bartragh Island, Co. Mayo, at an altitude estimated by the pilot to be six to seven hundred feet, the engine cut out. The pilot made one attempt to restart the engine without success, before carrying out a forced landing on a sandy beach on the south-western side of the island. The nose landing gear and right main landing gear collapsed during the landing and detached before the aircraft came to rest. The Pilot and passenger were uninjured and exited the aircraft unaided. There was no fire.

Probable Cause
The aircraft’s engine cut out, at a low altitude, resulting in a forced landing during which the aircraft sustained substantial damage.
Contributory Cause(s)
1. Operating in meteorological conditions that were conducive to serious carburettor icing.
2. The carburettor heat was OFF in the minutes preceding the event.
3. The higher volatility of automotive gasoline (MOGAS), in particular winter grade automotive gasoline, and a probable higher than normal water content, increased the likelihood of carburettor icing.
4. Vapour lock in the aircraft’s fuel system, which is more likely when MOGAS is used, may have been a factor.
