AD NUMBER: 2019-19-16

PRODUCT: Certain Airbus SAS Model A320-251N and -271N airplanes, and Model A321-253N airplanes.

ACTION: Final Rule.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2019-05-09, which applied to the aircraft listed above.

AD 2019-05-09 required repetitive detailed inspections of certain electrical harnesses for discrepancies, and corrective actions if necessary. AD 2019-05-09 also provided an optional terminating modification for the repetitive detailed inspections.

This AD retains the actions of AD 2019-05-09, and adds a requirement for a terminating modification for the repetitive detailed inspections, as specified in a European Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by reports of low clearance between the electrical harness and nearby hydraulic pipes in the inboard trailing edge of the wing.

DATES: This AD is effective November 13, 2019.

COST: The FAA estimates that this AD affects 14 airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:

• Retained actions from AD 2019-05-09: Labor: 6 work-hours × $85 per hour = $510 per airplane
• New proposed actions: Labor: 16 work-hours × $85 per hour = $1,360 per airplane. Parts: $8,900, Total cost per airplane: $10,260.

Estimated Costs of On-Condition Actions:

• Labor: Up to 8 work-hours × $85 per hour = $680 per airplane.
• The FAA has received no definitive data that would enable the agency to provide parts cost estimates.
