皇冠体育app

Jabiru UL-450, G-LEEE

Summary:

皇冠体育app aircraft was taking off from a private airstrip whose runway was orientated east west. 皇冠体育app runway was 550 m long, 5 m wide and its grass surface was dry. 皇冠体育app airstrip was surrounded to the east, west and south by woods, which encroached to within 50 m of the upwind end of Runway 27; the trees were estimated to be about 24 m high. 皇冠体育app surface wind was 270潞-300潞 at 6 kt; the visibility was in excess of 10 km and the temperature and dew point were +20潞C and +8潞C, respectively. Before the takeoff on Runway 27 the pilot carried out a power check and checked the operation of the carburettor heat. All appeared normal. Acceleration during the take-off felt normal but the pilot reported that the aircraft lifted off further down the runway than usual. 皇冠体育appreafter the aircraft鈥檚 acceleration and rate of climb 鈥榙id not feel right鈥�, although the engine rpm was indicating take-off power. Mindful of the trees at the upwind end of the runway the pilot decided to land immediately. He misjudged the flare and the aircraft, having drifted to port, landed on its left main landing gear in long grass at the side of the runway. 皇冠体育app left main landing gear collapsed as the aircraft ground looped to the left and the nose leg detached in the process. 皇冠体育app propeller struck the ground and the aircraft came to a stop facing south. 皇冠体育app pilot was uninjured and there was no fire. 皇冠体育app pilot considered that the surface wind speed may have dropped giving rise to the aircraft鈥檚 seemingly reduced rate of climb. He concluded that his concern about this, coupled to misjudgement of the flare and lack of appreciation of the drift to the left, had caused the accident. 皇冠体育app report referred to CAP 428, entitled 鈥楽afety Standards at Unlicensed Aerodromes鈥�, and the advice on assessing an aircraft鈥檚 take-off performance in General Aviation Safety Sense Leaflet number 7B, entitled 鈥楢eroplane Performance鈥�.
