Incident
On 23 June 1999 at 1820 UTC, an Antonov AN-2T, registration LY-ASA, was landing at Porthcurno Airstrip, Cornwall, when it overran the perimeter hedge and a dry stone wall. The aircraft sustained damage to the engine cowlings, propeller, landing gear, and both wings. The pilot, who was wearing a lap-only torso restraint, escaped without injury.
Aircraft and Pilot
The aircraft, an Antonov AN-2T, was manufactured in 1972 and powered by one PZL Kalisz ASZ-62-1R turboprop engine. The pilot held an Airline Transport Pilot's Licence, was 63 years old, and had 4,500 hours total flying experience, with 90 hours on type. In the 90 days preceding the accident, he had flown 40 hours, including 15 hours in the last 28 days.
Sequence of Events
The pilot elected to land into the wind, which was from 280° at 6 to 8 knots. The landing field was an open grass strip that sloped upward to a crest and then downward. The grass was moist. The touchdown was normal, but the aircraft did not stop before reaching the perimeter hedge and dry stone wall at the end of the strip. The pilot reported that he had overestimated the braking effectiveness on the moist, downward sloping grass surface.
