Officials with Sikorsky and Cougar Helicopters are inspecting the main gearbox on an S-92 chopper to find out what caused a hairline crack on the critical component.
A spokesman for Cougar said today a crew from Sikorsky is taking extra time examining the gearbox mounting feet, a day after the fracture was found on the helicopter when it returned from a training mission off Nova Scotia.
Christian Kittleson says they expect the helicopter will be back in service by Friday.
Two international aviation regulatory agencies recently issued airworthiness directives that mandate visual inspections of the mounting feet after every 10 hours of flight.
Cougar engineers were doing a standard inspection Monday when they discovered the crack on the mounting feet that attach the main gearbox to the airframe.
It is the same make of helicopter that was involved in a fatal crash off Newfoundland last March, although the cause of that crash was not linked to the same issue.

    Let's see a photo of this 'hairline' fracture. It was probably completely separated but barely held on elsewhere.
