Accident Overview
On 15 May 2000 at 1048 hours, a Cessna 152, registration G-BPVJ, crashed at Hambleton Hill, approximately 15 miles north of Leeds Bradford Airport. The aircraft was destroyed in the accident, and both occupants—an instructor and a student—sustained serious injuries.
Flight Details
The aircraft, manufactured in 1978, was powered by a single Lycoming O-235-L2C piston engine. The flight was a training sortie as part of the student's Basic Commercial Pilot's Licence (BCPL) course. The pre-flight briefing covered stall/spin awareness, including entry and recovery techniques. The instructor noted uncertainty about completing spin training due to cloudbase. Forecast weather included light southerly winds, visibility 6 km in haze, and scattered cloud at 4,000 feet.
The aircraft departed Leeds Bradford Airport Runway 14 at 0944 hours and left the control zone northbound. The instructor established contact with Linton-on-Ouse for a radar information service. Both pilots used headsets and an intercom system.
Sequence of Events
After completing several stalls, the instructor directed the student to enter a left spin, reviewing the entry technique. The student, who had prior aerobatic and spinning experience, entered the spin positively at 50 kt with a small amount of power applied. The student later could not recall details. The instructor stated that when he asked the student to recover, there was initially no response; he then closed the throttle. When the student again failed to act, the instructor took control and attempted recovery, but the aircraft did not respond. The instructor experienced shock at the lack of recovery, as the aircraft had always recovered easily in his experience. Full corrective control inputs appeared ineffective; he returned controls to neutral, checked flap and throttle positions, reapplied opposite rudder and forward column, but the aircraft still did not recover. He experimented with other control column positions and power settings. The aircraft then broke out of the spin suddenly; the instructor leveled the wings and raised the nose just above the horizon before impact.
The aircraft struck the ground—a wet moorland area—in a level attitude, bounced forward 23 metres, struck the ground again, and broke apart. Rescue helicopters arrived at 1220 hours; both occupants had to be cut free and were airlifted to a local hospital.
Aftermath
Linton-on-Ouse lost contact with the aircraft at 1048 hours and contacted Leeds Approach. Overdue action was initiated at 1109 hours, and the wreckage was located by another aircraft at 1139 hours. Radar data showed the aircraft climbing to 3,600 feet amsl, then entering a steep descent; the last recorded contact was at 2,000 feet amsl. The accident site elevation was 970 feet amsl, with terrain rising to 1,500 feet within 5 nm. The flying training organisation's Operations Manual prohibited spin entry below 4,000 feet agl and required recovery completion by 3,000 feet agl.
Background
The instructor, aged 32, held an Airline Transport Pilot's Licence with 3,800 total flying hours, including 1,100 on the Cessna 152. The aircraft was fitted with lap and single shoulder straps worn by both pilots. Spin training is required for BCPL and Flight Instructor courses but not for JAR CPL/ATPL licences. The Cessna 152 normally recovers readily from spins with correct technique; factors that may delay or prevent recovery include lateral imbalance, adverse centre of gravity, power remaining on, incorrect recovery technique, or recovering after a large number of turns.
