ACTION: Final Rule.

SUMMARY: The FAA is revising Airworthiness Directive (AD) 2013-21-05 for the aircraft listed above.

AD 2013-21-05 required an initial and repetitive inspections of certain bearings and modifying the floor and a rod. Since we issued AD 2013-21-05, we have determined that modifying the floor and rod removes the unsafe condition.

This AD retains the requirements of AD 2013-21-05 but removes the repetitive inspections.

DATES: This AD is effective December 21, 2018.

COST: The FAA estimates that this AD affects 304 helicopters of U.S. Registry and that labor costs average $85 a work hour. Operators may incur the following costs in order to comply with this AD:

• About 10 work-hours to inspect the bearing, and no parts or materials are required, for a cost of $850 per helicopter.
• If necessary, replacing the bearing requires 3 additional work-hours, and parts cost $50, for a cost of $305 per helicopter. Repairing the floor requires 3 additional work-hours and a minimal cost for materials, for a cost of $255 per helicopter.
