AD: Bell Helicopter Textron, Inc. (Bell) Helicopters

AD NUMBER: 2017-15-02

PRODUCT: Bell Model 212 and Model 412 helicopters.

ACTION: Final Rule; request for comments.

SUMMARY:  This AD requires replacing certain oil and fuel check valves and prohibits installing them on any helicopter. This AD is prompted by a report of cracked or leaking check valves. These actions are intended to address an unsafe condition on these helicopters.

DATES: This AD becomes effective August 4, 2017. Comments must be received by September 18, 2017.

COST: The FAA estimates that this AD affects 161 (59 Model 212 and 102 Model 412) helicopters of U.S. Registry. They estimate that operators may incur the following costs in order to comply with this AD. At an average labor rate of $85, replacing each check valve (engine oil or fuel) will require about 1 workhour, and required parts will cost $85. For the Model 212, we estimate a total cost of $340 per helicopter and $20,060 for the U.S. fleet. For the Model 412, we estimate a total cost of $170 per helicopter and $17,340 for the U.S. fleet.

According to Bell's service information some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage by Bell. Accordingly, they have included all costs in the cost estimate.
