The NTSB said in its preliminary report that the pilot had made a “series of modifications” to the plane doors, which affected its “indicator system”

The homebuilt airplane that crashed into a California warehouse earlier this month appears to have had a door ajar while in flight, according to a preliminary report by the National Transportation Safety Board.

A small plane crashed near northbound Highway 101 in Goleta Wednesday afternoon, Santa Barbara County authorities said.

Everyone aboard a plane that collided with an Army helicopter near Washington, D.C., are feared dead, which would make it the deadliest U.S. air crash in nearly 24 years.

A witness saw the left main cabin door open during flight, and an examination of the door showed the interior handle was not in the locked position.

The door to a pilot's plane appeared to be ajar as it took off from Fullerton Airport, moments before it crashed into a warehouse, according to investigators.

Authorities believe that plane door may have been open before the small jet ended up crashing into a Fullerton warehouse, killing the pilot and his daughter.

An amateur-built plane that slammed into a furniture warehouse near Fullerton Airport, killing the pilot and his teenage daughter and injuring 19 victims on the ground, had defects in a door that appears to have contributed to the collision.
