IN FLIGHT FAILURE OF WING STRUCTURE

Issue 1 of this AD temporarily grounded a Discus bT aircraft while investigation of the cause was carried out. Issue 2 details the inspection and repairs (if needed) which must be carried out before the aircraft may be safely returned to service. During a flight in turbulent weather, a Discus CS lost 3.6 metres of the outer wing following a rough recovery from a uncontrolled very steep flight attitude. The failure was found to be the result of poor bonding between the upper spar cap and the spar web. LBA AD 2003-265/2 issued 2/09/2003.
