AIRCRAFT WAS RUN UP & HOVER TESTED. ALL SYSTEMS OPERATED SATISFACTORILY. THE HELICOPTER WAS RETURNED TO SERVICE AND FLOWN BACK TO IT'S MAIN BASE. SUBSEQUENT TO THIS FLIGHT MAINTENANCE PERSONNEL DECIDED TO PULL THE CYLINDER WHICH HAD FOULED AND REPLACED WITH OVERHAULED CYLINDER.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
