 operational difficulty, mechanical failure, or malfunction until shortly after passing the Carolina Beach "H" facility a short distance south of Wilmington, North Carolina.

At approximately 0233 a dynamite charge was exploded, initiated by means of a dry cell battery within the passenger cabin and at a point beneath the extreme right seat of seat row No. 7.

Mr Julian A. Frank was in close proximity to the dynamite charge when the detonation occurred.

The dynamite explosion severely impaired the structural integrity of the aircraft and after making a wide descending right turn, it experienced inflight disintegration and crashed 1-1/2 miles northwest of Bolivia, North Carolina, at 0238.

The Board determines that the probable cause of this accident was the detonation of dynamite within the passenger cabin.
