NTSB investigations: Pratt & Whitney W-S1H&S3H, 2012

0 cases on aircraft whose registry engine model is Pratt & Whitney W-S1H&S3H, where the first occurrence was “Airframe/component/system failure/malfunction”. 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.
