The Bolkow 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 The nose landing gear was retracted after take-off, as normal.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.
