ACTION: Final rule; request for comments.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2019-21-08 for the aircraft listed above.

AD 2019-21- 08 required inspecting the right aileron flight control cable end fittings (terminal attachment fittings) and replacing any damaged cable assembly.

This AD retains all of the actions of AD 2019-21-08 but removes Models K35, M35, N35, and P35 from the applicability.

This AD was prompted by a comment the FAA received that AD 2019-21-08 should not apply to Models K35, M35, N35, and P35 airplanes.

DATES: This AD is effective November 22, 2019. The FAA must receive any comments on this AD by January 9, 2020.

COST: The FAA estimates that this AD affects 3,161 airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:

• Inspection of the right aileron cable end fittings
• 5 work-hours × $85 per hour = $425 per airplane.

On-Condition Costs

• Replacement of a forward aileron cable assembly - Labor: 6 work-hours × $85 per hour = $510 per airplane. Parts: $1,123. Cost per airplane: $1,633.
• Replacement of an aft aileron cable assembly - Labor: 4 work-hours × $85 per hour = $340 per airplane. Parts: $785. Cost per airplane: 1,125
