Cause of All Nippon aircraft landing on 2 wheels established.

It’s thought that the Nippon aircraft, which landed on only two wheels, had a detached bolt resulting in the landing gear getting stuck inside the fuselage.

The bolt, which is positioned in the joint of the arm that opens and shuts the door, had become unhinged thus resulting in the door becoming un-operational.

Investigators have not yet found the missing bolt and the reason why the bolt broke off is still being looked into.

This type of case isn’t unheard of in Japan, there have been three other incidents where the same model aircraft has had problems with the landing gear.

Luckily nobody was injured on the flight.
