Cougar Flight 232 was shut down upon arrival at the Hibernia Gravity Based Structure (GBS) after experiencing engine fuel bypass indications on both engines. The aircrew awaited the arrival of maintenance crew. Overnight the Aircraft Maintenance Engineers, in consultation with the engine manufacturer, conducted all required maintenance procedures. The helicopter was subsequently flight tested and certified serviceable on the morning of October 7. Cougar aircrew then returned the aircraft to St. John’s without further incident.
