What happened
On 29 May 2012, a Scheibe SF2D C Falke, registration G-BPZU, was conducting annual field landing training near Droke Lane, East Dean, Chichester. The flight involved an experienced instructor and a student, both members of a local gliding club. The weather conditions were characterized by clear skies, good visibility, and a temperature of approximately 22°C, with a light south-westerly breeze.
During the training exercise, the aircraft approached a field containing a firm, smooth crop. This particular field featured a significant upslope directed towards the north-west. As the aircraft reached approximately 50 ft agl, the instructor took control of the aircraft to execute a go-around. To maintain a safe speed of 50-55 kt and avoid illusions caused by the local horizon, the instructor pitched the nose up.
While the student suggested turning left toward lower ground, the instructor opted to continue straight ahead to avoid the risk of a spin at low speed. As the aircraft approached the far end of the field, the instructor realized the trees at the boundary were too close. In an attempt to fly between two tall trees, the aircraft clipped a tree and crashed into dense brambles and brush. The two crew members escaped the extensive damage with only minor bruises.
The investigation
The AAIB examined the circumstances surrounding the maneuver and the aircraft's performance. The investigation noted that the aircraft was within its weight limits and had been performing normally throughout the day. The investigators also looked into the environmental factors, including the terrain and the impact site, which suggested that the thick vegetation may have helped decelerate the aircraft during the crash.
Findings
- The instructor's late decision to execute the go-around contributed to the proximity of the trees.
- There was a potential lack of awareness regarding the severity of the field's upslope and the distance to the tree line.
- High ambient temperatures may have reduced the performance of both the engine and the aircraft.
- The instructor may have been experiencing slight fatigue following two days of intensive flying in hot weather.
- The absence of a headwind and other wind effects at low altitude may have influenced the aircraft's climb capability.
