NTSB investigations: Pratt & Whitney R1340 series
32 cases on aircraft whose registry engine model is Pratt & Whitney R1340 series, where the defining event was Low altitude operation/event. 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.
