Narrative:
The nose wheel of a Cessna 421C Golden Eagle II collapsed during landing at Bournemouth Airport - EGHH. Nobody was hurt in the incident. There were three persons on board (pilot and two passengers)

According to the AAIB interim report: "The aircraft had made a standard visual approach to Runway 26 at Bournemouth Airport followed by a normal touchdown close to the runway aiming markers and on the runway centreline. As the nosewheel was lowered, the pilot heard a “whining, rubbing noise” from the nosewheel region and felt a slight nose wheel vibration or shimmy.

He continued to decelerate to about 50 knots on the centreline at idle power and without using the brakes, having used about 500 metres of the runway. At this point the vibration increased markedly and the aircraft veered sharply to the left through about 45 degrees. Despite application of full right rudder and toe brake, the pilot realised that the aircraft was going to leave the paved surface so he applied maximum braking to slow it as much as possible.

The aircraft ran onto the grass at an estimated speed of about 10 to 15 knots, collapsing the nose landing gear (NLG) as it did so, before stopping a few metres from the runway edge. After shutting down the aircraft, all the occupants evacuated through the overwing emergency exit without any injury. The aircraft was resting on its main landing gear and the nose fuselage and the propeller tips had struck the ground.

It was recovered to a hangar for examination where it was found that the NLG leg had folded into the retracted position due to overload failure of the downlock mechanism. The nosewheel tyre had completely deflated due to what appeared to be massive wear of the sidewall on the right side. The inner tube had been liberated from the inside and was wrapped around the axle".

Damage sustained to airframe: Propellers, nose landing gear, nose bay doors and radome damaged, engines shock-loaded
