What happened
On 16 January 2001, a Piper PA-28-161, registration G-BRRM, was conducting a routine six-monthly dual check flight at Rochester Airport, Kent. The flight was performing touch-and-go landings on Runway 34. During the approach, the crew initially considered a go-around but ultimately decided to proceed with the landing. The aircraft was configured with the first two stages of flap, and the airspeed was reduced to approximately 70 kt.
While the aircraft was on the runway, the instructor attempted to adjust the flap lever to the first stage. However, the lever missed the intended gate, resulting in the selection of the flap up position. Although the pilot applied full power for the subsequent takeoff, the airspeed failed to increase as expected. As the aircraft approached the end of the 773-metre runway, the instructor took control to fly the aircraft off the surface. During the excursion, the left main landing gear struck a perimeter fence and detached. The aircraft then veered left and came to rest in bushes and wire mesh fencing. Both crew members sustained minor injuries and escaped the aircraft via the door.
The investigation
Investigators examined the runway conditions and the mechanical actions of the crew during the landing sequence. The runway surface was noted to be generally wet and potentially waterlogged in certain areas. Air traffic services reported that the aircraft touched down with approximately 390 metres of the landing distance available remaining. The investigation focused on the sequence of flap selection and the subsequent loss of performance during the takeoff roll.
