Probable cause
An undetermined problem with the ignition system. A factor related to the accident was: the pilot's failure to properly secure the airplane or obtain proper assistance.
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
The pilot was unable to start the engine & decided to pull the prop through by hand. He stated he removed the ignition key, pulled the throttle to idle & the mixture to idle cut-off. When he turned the prop, the engine started & the acft began to taxi. It traveled into a parked Cessna skyhawk, which was pushed into a Cessna skylane & a Piper arrow. No malfunction was verified that would have allowed the engine to start.
