6 cases on aircraft whose registry engine model is Pratt & Whitney R1340 series, where the first occurrence was “Loss of engine power(total) - 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.
