The National Transportation Safety Board has released preliminary findings from its investigation into a fatal aircraft crash that occurred at Ryan Airfield near West Glacier on Aug. 12 .
The single-engine aircraft was attempting to land when it crashed, killing the pilot, who was the sole occupant of the plane. Three people have died in fatal crashes at the airfield this summer.
According to the NTSB report, the pilot made multiple landing attempts before the fatal crash occurred.
The plane attempted to land twice but bounced both times during approach. On the third landing attempt, the aircraft's right wing clipped a tree located next to the runway.
The impact with the tree, which occurred 55 feet above ground level, caused the plane to roll and flip upside down before nose-diving
