Description UPDATE : TSB A06A0010: CHI22, a Cougar Helicopters Sikorsky S-92A, with 19 passengers and two flight crew onboard, was enroute from St. John's, NL to the Henry Goodrich oil platform and was approximately 35 NM Southeast of St. John's when the number two engine chip light illuminated (General Electric CT7-8A). The crew followed checklist procedures and reduced the #2 engine power to idle and elected to return to St. John's. The crew did not initially declare an emergency, however, ten minutes prior to landing requested ERS. The aircraft landed without further incident. After the aircraft landed, maintenance inspected the chip plug on the #2 engine and in consultation with the engine manufacturer, it was felt that the metal found on the chip plug was from the #3 bearing. This engine had a total of 42.2 hrs time in service since new. The engine was replaced with a new engine before the aircraft was returned to service.
