Narrative:
ZSLS-Wroclaw/PZL-Bielsko SZD-24-4A Foka 4A G-DBZZ was written of (destroyed) 8.8.2010 in a fatal accident at Bicester, Oxfordshire. Glider pilot Amy Barsby (aged 25) died after the glider she was piloting crashed in a field on the edge of Bicester. Witnesses tonight told how they heard a crack and saw a glider spiral out of the sky at the Bicester Airfield (EGDD) in Oxfordshire.

Emergency services were called to the Buckingham Road site at 3.15pm after reports a glider had come down at the Bicester Gliding Centre, home of the Windrushers Gliding Club.

The woman, from Lancashire, was the only occupant of the glider and was pronounced dead at the scene by paramedics. Witnesses described seeing the wings come off before the crash.

A spokesman for the Air Accident Investigation Branch (AAIB) said its investigators were trying to determine the cause of the crash.

The subsequent AAIB report concluded:

"Examination of the wreckage showed that wings had become detached in flight, and had fallen separately from the fuselage, coming to rest inverted to the right of Runway 36. The wings, which were still attached to each other, were largely intact except for a 2.15-metre section of the left wing inboard trailing edge, which had detached on impact with the ground. Examination of the wing root fitting in the as-found inverted position, revealed that the lower bevel bolt was only partially engaged in the lower right wing attachment lugs and the lower left wing attachment lug was disengaged from the lug stack.

The investigation determined that when the aircraft was rigged, the lower bevel bolt of the wing main fitting had not fully engaged with the lower lug stack of the main spar joint and it was not possible to detect this condition. As a consequence, when the glider became airborne, the partially secured joint was unable to sustain the wing bending moments associated with the winch launch and the lower bevel bolt failed. This allowed the lower attachment lugs to disengage and the wings to fold upwards and separate from the fuselage"

Registration G-DBZZ cancelled by the CAA as "destroyed" 18.02.2011
