Probable cause
The loss of engine power for undetermined reasons. Factors were the smoke in the cockpit and loss of outside visual reference.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During spraying operations the pilot experienced a power loss and the cockpit filled with smoke. After the loss of outside references and engine power the airplane descended uncontrollably and struck a telephone pole, followed by further descent to ground impact. The smoke source and reason for the loss of engine power was undetermined.
Factual narrative
On May 4, 1993, at 0900 central daylight time, a Rockwell S-2R, N424OX, was substantially damaged while maneuvering near Lookeba, Oklahoma. The commercial pilot, also the owner/operator, sustained minor injuries. Visual meteorological conditions prevailed.
During an interview with the pilot, conducted by a Federal Aviation Administration (FAA) inspector, he stated that he had completed a spray run and was maneuvering for the next pass when the cockpit filled with smoke and the engine lost power. He further reported that after he lost engine power his right wing struck a telephone pole and he descended uncontrollably to ground impact. The operator was unable to determine why the engine lost power. As a result of a bankruptcy proceeding the was removed from the warehouse and could not be located for additional inspection.
