Incident at ST. JOHN'S INTL NL (CYYT) (FOD (foreign object debris))

Summary

2005-09-26: Maintenance & Manufacturing Update: The aircraft did not have an in flight engine shut down. The aircraft returned to base due to a T5 temperature difference between the two engines of 40 to 50 degrees. The engine was never shut down. The incident started on take-off from St. John's when the crew heard a loud noise when they pulled power for take-off. They scanned all the engine and flight instruments and no anomalies were noted with the exception of a momentary torque fluctuation that returned to normal immediately. The departure was conducted normally. After attaining level cruse the T5 difference was noted and the crew elected to return to base to investigate this problem. When the aircraft arrived in St. John's, maintenance inspected the aircraft and engines and noticed a tissue-like material partially blocking the engine inlet guide vanes. The material was removed and found to be a napkin. The engine was inspected, ground run and test flown and all parameters were found normal.
2005-09-26: TSB Update A05A0126: The S-61 was in the hover about to depart on Runway 20 for the second flight of the day when the crew heard a bang. The aircraft was set down and a visual inspection for open doors and panels was conducted. Engine parameters on both engines were normal. The aircraft then departed for an IFR trip to the Rowan Gorilla drilling platform. After leveling off at 7000 feet the crew noticed that the #2 engine (GE CT 58-140-2 serial 296011 TSO 670 - installed 09 Sept 2005) T5 was 30 degrees higher than the #1 engine, and the Ng was 2 percent higher: on previous flights they had matched closely. The crew advised ATC that they were canceling IFR and returning to CYYT due to an engine anomaly. No emergency was declared, Halifax RCC was advised, and the flight landed without incident using both engines. The remnants of a shredded paper napkin were found in the inlet area of the #2 engine. The napkin was removed and the aircraft was returned to service. The operator has advised airport authorities of a FOD occurrence.
2005-09-23: CH182, Sikorsky S61, enroute Saint John?s (CYYT) to Rowan Gorilla Drilling Platform at 7000 ft. At approximately 40nm SE of CYYT the pilot advised he was shutting down one engine, canceling IFR and returning to CYYT. No emergency was declared, Halifax RCC was advised, and the flight landed at 1915z without incident. TSB Case Closed.
