AD NUMBER: 2017-25-05

PRODUCT: All Airbus Model A318 series airplanes; Model A319 series airplanes; Model A320-211, -212, -214, - 231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes.

ACTION: Final Rule.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2012-23-10, which applied to the aircraft listed above.

AD 2012-23-10 required modifying the affected slide rafts. This AD retains the requirements of AD 2012-23-10. This AD also requires replacing each escape slide pack assembly having a certain part number with a new escape slide pack assembly.

This AD was prompted by reports of the escape raft inflation system not deploying when activated due to the rotation of the cable guide in a direction that resulted in jamming of the inflation control cable.

COST: The FAA estimates that this AD affects 959 airplanes of U.S. registry. Cost of compliance for modification retained from the previous AD is estimated to be $1,956 per aircraft for parts and labor. The estimated cost of replacement and modification to be $510 per aircraft.

DATES: This AD is effective January 16, 2018.
