Background
Two ATP-rated pilots were conducting an IFR flight plan in actual instrument weather conditions, returning to their home base airport. Communications with air traffic control were normal throughout the flight.
Incident Sequence
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, which was the last transmission heard from the pilots and was routine. The aircraft then crashed into a wooded area just beyond the outer marker.
Post-Accident Examination
The aircraft was destroyed in a post-impact fire. Examination of the wreckage revealed evidence indicating that the left engine was producing less power than the right engine at the time of impact.
