Maintenance History
The engine had undergone a 100-hour inspection by company maintenance personnel eight days prior to the accident. The inspection checklist included an examination of the fuel control linkage for security.
Probable Cause
The probable cause of the accident was the improper inspection of the aircraft by company maintenance personnel, which resulted in an unsafetied and disconnected fuel control arm.
