Key Takeaways:

Federal accident investigators are focusing on a left main landing gear failure as the cause of a fatal ground collision between a Learjet 35A and a parked Gulfstream G200 at Scottsdale Airport.
Video evidence shows the Learjet 35A's left main landing gear was trailing and not down-and-locked on approach, leading to the aircraft veering off the runway upon touchdown.
The NTSB's preliminary report indicates a missing aft trunnion pin and excessive grease in the left main landing gear assembly, and the flight crew was previously involved in another landing mishap.

Federal accident investigators are focusing on landing gear failure as a possible factor that led to the death of one person and injured three others when two business jets collided on the ground at Scottsdale Airport (KSDL) in Arizona last month.

The February 10 accident occurred around 2:39 p.m. MST during VFR conditions when a Learjet 35A arriving from Austin, Texas, veered off the runway and struck a parked Gulfstream G200.
