SHIRLEY, N.Y. (AP) — Federal transportation authorities say a pilot was aware his single-engine plane had problems when it crashed last August, killing him and one of two passengers interested in buying the aircraft.

A NTSB report says David McElroy of Orient and his mechanic "represented" to the potential buyers that the plane was airworthy when it wasn't.

According to Newsday ( ), the report found the aircraft had a faulty tachometer and a lack of engine power during a test flight three days before the crash.

A tachometer measures engine revolutions.

The report says the mechanic never "signed off" on the inspection and didn't restore the plane to service.

Erik and Jane Unhjem were interested in buying the plane. She died in the crash; her husband survived.

McElroy's family declined to comment.
