Airworthiness Directive · Amendment 39-14868 · Airbus Model A300 B2 and B4 Series Airplanes
Airbus Model A300 B2 and B4 Series Airplanes
This AD applies to all Airbus Model A300 airplanes; certificated in any category; except the following airplanes:
(1) Model A300 B4-220, A300 B4-203, and A300 B2-203 airplanes in a forward facing crew cockpit certified configuration;
(2) Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes;
(3) Model A300 B4-605R and B4-622R airplanes;
(4) Model A300 F4-605R and F4-622R airplanes; and
(5) Airbus Model A300 C4-605R Variant F airplanes.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300 B2 and B4 series airplanes. This AD requires revising the airplane flight manual (AFM) to include procedures for resetting the trim and pitch trim levers after each landing, determining which servomotor moves the pitch trim control wheel, and doing applicable other specified actions. This AD also provides for optional terminating actions for those requirements. This AD results from a report of a sudden nose-up movement after disengagement of the autopilot in cruise. We are issuing this AD to ensure that the flightcrew is aware of the procedures for resetting the trim and pitch trim levers after each landing and to prevent failure of the servomotors of the pitch trim systems during flight. Failure of the servomotors of the pitch trim systems could result in uncommanded nose- up movement of the control surface of the pitch trim systems after disengagement of the autopilot in cruise.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 14 days after the effective date of this AD, do the action specified in paragraph (f)(1) or (f)(2) of this AD.
(1) Revise the Normal Procedures section of the Airbus A300 Flight Manual to include the information in Airbus A300 Temporary Revision (TR) 4.03.00/04, Issue 02, dated November 18, 2003, as specified in the TR.
Note 1: This may be done by inserting a copy of TR 4.03.00/04, Issue 02, in the AFM. When the TR or the statement specified in paragraph (f)(2) of this AD has been included in the general revisions of the AFM, the general revisions may be inserted in the AFM, provided the relevant information in the general revision is identical to that in the TR or paragraph (f)(2) of this AD.
(2) Revise the Normal Procedures section of the Airbus A300 Flight Manual to include the following operational procedure. This may be done by inserting a copy of this AD in the AFM.
—Set TRIM to 1° UP
—Set both PITCH TRIM levers to OFF
Note: Check pitch trim wheel and report any movement to maintenance.”
Following accomplishment of the AFM revision required by paragraph (f) of this AD: After each landing and before shutting down the engines, do the AFM procedures specified in Airbus A300 TR 4.03.00/04, Issue 02, dated November 18, 2003, or paragraph (f)(2) of this AD.
Before further flight after any movement reported in accordance with paragraph (g) of this AD, determine which servomotor moves the pitch trim control wheel, and do applicable other specified actions in accordance with Airbus A300 TR 22-001, dated April 11, 2003, to Chapter 22-23-00 of the Airbus A300 Fault Isolation Manual.
Note 2: Airbus A300 TR 22-001 contains a typographical error. The TR incorrectly refers to “MM 22-23-39” as the appropriate source of service information for replacing the pitch trim actuator; the correct reference is “MM 22-23-29.”
(i) Replace the pitch trim servomotors in the attachment area of the horizontal and vertical stabilizers with new servomotors, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-22-0119, dated May 13, 2005.
Note 3: Airbus Service Bulletin A300-22-0119, dated May 13, 2005, refers to Thales Service Bulletin V1AM-22-005, Revision 01, dated July 27, 2005, as an additional source of service information for doing the replacement.
Within 12,000 flight hours after replacing one or both servomotors in accordance with paragraph (h) or (i) of this AD, or within 6 months after the effective date of this AD, whichever occurs later, do the preventative maintenance task of the pitch trim servomotor(s), in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-22-0120, excluding Appendix 01, dated May 13, 2005. Repeat the preventative maintenance task thereafter at intervals not to exceed 12,000 flight hours.
Note 4: Airbus Service Bulletin A300-22-0120, dated May 13, 2005, refers to Thales Service Bulletin V1AM-22-006, Revision 01, dated July 26, 2005, as an additional source of service information for doing the preventative maintenance task.
After accomplishing the actions specified in paragraph (i) and the initial task in paragraph (j) of this AD, the AFM revision required by paragraph (f) of this AD may be removed, and the requirements of paragraphs (g) and (h) of this AD are no longer required.
Although Airbus Service Bulletin A300-22-0120, dated May 13, 2005, specifies to submit certain information to the manufacturer, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
