Model A319-111, -112, -113, and -114; A320-111, -211, -212, and -214; and A321-111, -112, and -211 series airplanes; certificated in any category; powered by CFM56-5A or -5B engines having any thrust reverser blocker door actuator part number D23090000-6.

Required as indicated, unless accomplished previously. To prevent inadvertent deployment of the thrust reverser door, which could result in reduced controllability of the airplane, accomplish the following: Repair History (a) If, from a review of the maintenance records, it can be positively determined that the thrust reverser blocker door actuator was never overhauled by “TRW—Lucas Repair Center—Englewood, New Jersey,” then no further work is required by this AD. Inspection (b) Before the actuator of the thrust reverser blocker door accumulates 7,000 total flight cycles since its last overhaul, or within 500 flight hours after the effective date of this AD, whichever occurs later: Do a general visual inspection to identify the part number and serial number of the actuator, in accordance with Rohr CFM56-5A/-5B Service Bulletin RA32078-112, Revision 1, dated February 6, 2002. Look for affected serial numbers as listed in paragraph 1.A(1) of the service bulletin. Note 1: For the purposes of this AD, a general visual inspection is defined as: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.” (1) If no affected serial number is found, no more work is required by this paragraph. (2) If any affected serial number is found: Before further flight after doing the inspection required by paragraph (b) of this AD, replace the affected actuator with a new or reworked part in accordance with the service bulletin. (c) An inspection and rework done before the effective date of this AD in accordance with Rohr CFM56-5A/-5B Service Bulletin RA32078-112, dated October 22, 2001, is acceptable for compliance with the applicable requirements of this AD. Parts Installation (d) As of the effective date of this AD, no person may install, on any airplane, an actuator of the thrust reverser blocker door having a part number and serial number listed in paragraph 1.A.(1) of Rohr CFM56-5A/-5B Service Bulletin RA32078-112, Revision 1, dated February 6, 2002, unless the actuator has been reworked in accordance with the service bulletin. Alternative Methods of Compliance (e) In accordance with 14 CFR 39.19, the Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate, is authorized to approve alternative methods of compliance for this AD. Incorporation by Reference (f) Unless otherwise specified in this AD, the actions must be done in accordance with Rohr CFM56-5A/-5B Service Bulletin RA32078-112, Revision 1, dated February 6, 2002.
