What happened
On 26 October 2018, a Piper PA-28-161 Cherokee Warrior II, registration G-BSZT, was performing a private sightseeing flight from Shoreham Airport. The pilot, accompanied by three passengers, was utilizing this specific aircraft because their usual type was unavailable due to maintenance. After receiving clearance for departure from Runway 02, the pilot commenced the takeoff roll.
As the aircraft reached a speed of 70 KIAS and the nose pitched up by approximately 3°, a sudden gust of wind caused the aircraft to yaw to the left. The pilot attempted to correct the deviation by pushing the control column forward to keep the nosewheel on the pavement, but the aircraft drifted off the runway. Witnesses observed the aircraft bouncing across the grass, potentially becoming momentarily airborne due to the uneven terrain. The aircraft continued at high speed across the airfield, eventually striking undergrowth and coming to a halt in a ditch. There were no injuries to the pilot or the three passengers.
The investigation
The investigation examined the meteorological conditions and the pilot's recent flying history. Weather data indicated a crosswind from the left of up to 13 knots during the period surrounding the accident. The investigation also noted that while the pilot had recent flying experience, he had not operated this specific aircraft model for seven months.
Findings
- The aircraft departed the runway due to the combined effect of a crosswind and an unexpected wind gust.
- The pilot's attempt to maintain directional control was unsuccessful as the aircraft veered left.
- The rough surface of the grass area likely caused the aircraft to bounce during the excursion.
- The pilot may have underestimated the required rudder input needed to counteract the crosswind, potentially due to the seven-month lapse in type-specific experience.
