Accident
On 22 October 2011 at 1625 UTC, a Piper PA-28-140 Cherokee, registration G-ZANG, departed the runway during an aborted takeoff at Netherthorpe Airfield, South Yorkshire. The aircraft collided with bushes beyond the end of Runway 24 before crossing a road and coming to rest in a field. Damage was sustained to the propeller, engine, both wings, nosewheel, instrument panel, and windows. The pilot and sole passenger received minor injuries.
Flight History
The pilot had flown from Blackpool to Netherthorpe earlier that day with fuel below the tabs, indicating approximately two-thirds full tanks. The aircraft was not refuelled after arrival. For the return flight, Runway 24 (takeoff run available 490 metres) was selected. The pilot reported that the headwind component had reduced near the anticipated takeoff point. After selecting the first stage of flap, he realised insufficient runway remained and decided to abort. Despite his efforts, the aircraft could not be stopped before overrunning the runway.
Weather and Performance
A weather observation taken before the accident recorded a temperature of 13°C, CAVOK conditions, and a wind of 180° at 8-10 kt. Conditions were reported as dry, but the pilot noted the grass on the runway was damp. The pilot held a Private Pilot’s Licence with 203 hours total flying experience, of which 127 were on type. He had flown 8 hours in the last 90 days and 4 hours in the last 28 days.
Operational Information
Reference to a generic flight manual for the aircraft type indicated a still-air takeoff distance of 427 metres from rest to 50 ft for an assumed weight of 1,500 lb, accounting for the 1.9% uphill gradient and airfield elevation of 250 ft, valid for a dry tarmac surface with flaps retracted. Notes in the manual stated that this distance should be increased by 6.5% for a short, dry grass runway, giving a revised distance of 455 metres. No data were provided for takeoff with flaps extended, though the manual did not provide specific figures for that configuration. The pilot did not supply sufficient information for an accurate weight assessment; the 1,500 lb value was a typical weight for two average occupants and half to two-thirds fuel. The performance charts indicated that at maximum takeoff weight (approximately 2,150 lb), the available runway length was insufficient.
