AAIB investigation to Diamond DA42 Twin Star, G-CTCB

Left main landing gear partially collapsed after landing, Bournemouth Airport, Dorset, 28 April 2016.


Following a practice asymmetric power approach and a normal but firm landing, the left main landing gear ‘unsafe’ light started flashing, with accompanying aural warning. After shutting down the aircraft on the nearest taxiway it was discovered that the left main landing gear leg had partially collapsed. The aircraft manufacturer determined that this was caused by an overload failure of the bonding between the composite drag brace rib and the composite centre wing section.
