Probable cause

The CFI pilot failed to maintain flying speed, and the resultant inadvertent stall. Contributing to the accident was the existing low ceiling.

Analysis

The scheduled airplane had a dead battery and the flight instructor took an airplane that was not scheduled to be dispatched due to lack of a transponder, a microphone and radios. Approximately 20 minutes after takeoff, many witnesses saw the airplane coming out of the clouds, from the south-southeast, saw it cross over the airport, and then turn north. When it was north of the airport, it started a sharp right turn, the nose pitched down, and the airplane disappeared from view. It impacted almost straight down. A local weather observation by a local flight operation indicated 400 feet overcast ceiling and visibility of 2 miles.
