ACTION: Final Rule.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 95-26-13 for the airplanes listed above.

AD 95-26-13 required inspections, replacement, and adjustment of the oil cooler hose assemblies, as well as providing for a terminating action.

This AD retains all of the requirements of AD 95-26-13 and adds language to clarify those requirements.

This AD was prompted by several inquiries asking for clarification of the AD's applicability and compliance requirements.

The FAA estimates that this AD affects 23,643 airplanes of U.S. registry.

This AD retains the same actions as AD 95-26-13 and the costs do not add any cost burden than that already in effect by AD 95-26-13. The difference in the Costs of Compliance with this AD and AD 95-26-13 is that we use $85 an hour as a labor rate in 2016 as opposed to $60 per hour in 1995. The total cost estimate per airplane is $642.50, according to the FAA.

DATES: This AD is effective August 15, 2017.
