NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot aborted the takeoff in the twin-engine airplane due to a rough running engine. The airplane exited the end of the runway and struck an embankment. Postaccident examination and testing of the airplaneā€™s left engine revealed damage to the ignition harness and rough operation during a test run. Replacement of the worn harness resulted in normal operation during a second test run. Based on the available information, it is likely that the airplane's left engine experienced a partial loss of power due to the damaged ignition harness. The reason for the damaged ignition harness could not be determined.

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

A damaged ignition harness, which resulted in a partial loss of engine power.
