Federal investigators have released their accident report on the fatal airplane crash last year in Littlefield.

Investigators say a specific maneuver led to last year's deadly glider crash that killed the pilot,  79-year-old Eddie Hogland and his passenger,  13-year-old Taylor Brown.

The crash occurred on March 13, 2013.

Witnesses told investigators that the glider was flying approximately 2,000 feet above the ground when it appeared to perform a loop when one of the gliders wings separated from the fuselage, causing the glider to plummet to the ground.

Officials say the glider was not designed for aerobatic maneuvers.

Investigators determined that the loop placed too much pressure on the wing, causing it to break.

Investigators also determined that glue used to help secure the wing joints had deteriorated.
