Narrative:
A Boeing 737-300F freighter experienced a collapse of the right main landing gear after landing at the Honiara International Airport (HIR/AGGH), Solomon Islands.
The airplane sustained apparent substantial damage and no injuries have been reported to the three crew onboard.
Following touchdown, the aircraft rolled out for approximately 1200 m at which point the right hand main landing gear (MLG) gave way and the aircraft collapsed onto it’s right hand engine, continuing to travel approximately 400 m along the runway, before coming to a stop.

Pacific Express uses aircraft which are in the Toll Aviation livery, owned and flown by Airwork, NZ.

An investigation has determined that the cause of the MLG failure and resultant accident was the inappropriate rework (ie, machining and re-threading) of the tee-bolt fitting and the associated installation of a reduced size nut and washer, at the last overhaul in 2004.
