NTSB investigations: Pratt & Whitney JT9D-3A, 2012

0 cases on aircraft whose registry engine model is Pratt & Whitney JT9D-3A, where the first occurrence was “Loss of engine power(partial) - mech failure/malf”. Aircraft are matched to the registry by N-number and event date, checked against the reported serial number, make and model, so older matches can be wrong.
