AD NUMBER: 2019-22-04

PRODUCT: Certain Airbus SAS Model A320 series airplanes.

ACTION: Final rule

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 96-25-04, which applied to the aircraft listed above.

AD 96-25-04 required repetitive inspections of the wire looms in the wing and the horizontal stabilizer and in certain areas of the main landing gear (MLG) bays; repair or replacement, protection, and realignment, if necessary; installation of protective sleeves; and realignment of certain bundles.

This AD partially retains the requirements of AD 96-25-04 and requires modification of the wing electrical installation; as specified in a European Aviation Safety Agency (EASA) AD, which is incorporated by reference.

This AD was prompted by a determination that there were issues with protective sleeves previously installed as specified in AD 96-25-04.

DATES: This AD is effective December 24, 2019

COST: The FAA estimates that this AD affects 27 airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:

Retained actions from AD 96-25-04

• Labor: 62 work-hours × $85 per hour = $5,270 per aircraft.

New actions

• Labor: 25 work-hours × $85 per hour = $2,125 per aircraft.

The FAA has received no definitive data on the parts costs for the new actions.
