What happened
The two ATP-rated pilots were en route back to their home base airport, operating under an IFR flight plan in actual instrument weather conditions. Communications with air traffic control controllers remained normal throughout the flight. During a night localizer approach into Millville Municipal Airport, an ATC specialist observed the aircraft passing through the localizer track and issued a vector for re-interception. The aircraft was subsequently observed tracking inbound on course. The pilot reported crossing the outer marker (OM). This was the last transmission heard from the pilot and was routine. The aircraft crashed into a wooded area just beyond the OM and was destroyed in a post-impact fire.
The investigation
Post-accident examination of the wreckage revealed evidence to indicate that the left engine was producing less power than the right engine at impact.
