Introduction
On 20 August 2019, a Piper PA-28-181 Cherokee Archer II, registration G-BSIM, was substantially damaged during a takeoff from Runway 28 at Branscombe Airfield, Devon. The aircraft, manufactured in 1986, was operated by a private pilot with a Private Pilot’s Licence. The pilot, aged 30, had accumulated 136 hours of flying experience, with 60 hours on type. The flight was intended as a return to the home base at RAF Henlow.
Sequence of Events
According to the pilot's report, the takeoff was initiated with a reported wind from 180° at 9 knots. However, a moving image recording of the event showed that a windsock at the airfield indicated gusting wind speeds considerably higher than the reported value. The maximum demonstrated crosswind component for the aircraft type is 17 knots.
During the takeoff roll, the pilot experienced unsteady directional control. The nose of the aircraft lifted at a low speed. The aircraft became briefly airborne and then "weathercocked" into the wind, turning towards the airfield boundary hedge. The pitch angle increased, causing the aircraft to sink back onto its main wheels, and the tail contacted the ground.
The aircraft then became airborne again in a nose-high, low-speed condition. The pilot attempted to turn back towards the runway, but the aircraft "mushed" into the boundary hedge.
Damage and Injuries
The aircraft sustained substantial damage in the incident. There were no injuries to the pilot or the three passengers on board.
Comments
The AAIB commented that proper technique and practice are vital to achieve a safe crosswind takeoff, especially when the wind speed is close to the demonstrated maximum.
