ACTION: Final Rule.

SUMMARY: We are superseding Airworthiness Directive (AD) 2017-22-07, which applied to the airplanes listed above.

AD 2017-22-07 required repetitive inspections of the frame forks, and corrective actions if necessary. AD 2017- 22-07 also included optional modifications that constituted terminating action.

This AD requires modifying certain forward and aft cargo compartment doors, and related investigative and corrective actions.

This AD was prompted by an evaluation done by the design approval holder indicating that certain areas of certain cargo compartment doors are subject to widespread fatigue damage, and a determination was made that a modification of the frame forks must be done.

DATES: This AD is effective February 1, 2019.

COST: The FAA estimates that this AD affects 88 airplanes of U.S. registry Operators may incur the following costs in order to comply with this AD:

• Modification: 24 work-hours × $85 per hour = $2,040. Parts: Up to $240. Cost per airplane: Up to $2,280
• Inspection: 25 work-hours × $85 per hour = $2,125 per aircraft per inspection cycle.
