Piper PA-30 Twin Comanche, G-AVPS
Shortly after the aircraft touched down on a grass runway, its landing gear collapsed. Although the green landing gear ‘down locked’ light was illuminated prior to landing, it is likely that the nose gear leg was not in fact down and locked. The investigation found that misalignment of landing gear components on Piper Comanche aircraft can cause the landing gear to remain unsafe, despite cockpit indications to the contrary, and that failure of the nose gear to lock down prior to touch down will result in failure of the transmission system and collapse of the main gear on landing.
