NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot was taking off on runway 21. As he raised the tail for lift off (about 50 mph), the airplane 'abruptly swerved to left (90 degrees), [departed] the runway, crossed a dirt border about 6 feet wide, flipped on its back, and slid down to the bottom of a drainage ditch between the runway and the adjacent taxiway.' The pilot said the airplane was equipped with Goodyear 'expanded tube' brakes, known to lock up if overheated (brakes were used for landing and for taxi to takeoff). An airport mechanic attempted to turn the left main wheel by hand shortly after the accident, and found the wheel to be binding. The right wheel turned freely. Later, he tried again and the wheel turned freely.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

Overheating of the left brake, causing the wheel to lock. Factors were the pilot not being able to maintain directional control, a dirt berm, and a drainage ditch.
