Investigating agency: AAIU
Narrative:
The Bölkow Bo-209 Monsun aircraft, which was fitted with a retractable nose landing gear, took-off from runway 09 at Navan Airfield (EIHH) with two occupants on board. The nose landing gear was retracted after take-off, as normal. Following one circuit of the airfield, a landing on the same runway was carried out. During the landing roll, the propeller and the lower engine cowling made contact with the surface of the grass runway, as the nose landing gear had not been extended prior to landing. The aircraft’s propeller and engine cowlings sustained damage. The two occupants were uninjured and exited the aircraft unaided. There was no fire.

Probable Cause
The aircraft’s nose landing gear was not extended prior to landing, resulting in damage to the propeller and engine cowlings, and the engine being shock-loaded.
Contributory Cause(s)
1. Lack of operational familiarity and experience on the aircraft type.
2. The layout of the ‘FOR DESCENT’ checklist carried on board the aircraft and possible obscuration of some of its contents during the occurrence flight.
3. The activation point of the throttle position switch was closer to idle than the position specified in the aircraft’s ‘Technical Description’ document.
