AD 2001-13-13 Airworthiness Directives; Airbus Model A330 and A340 Series Airplanes

Models named: A330, A340 series. Read the applicability below — it usually turns on serial or part numbers too.

All Model A330 and A340 series airplanes, certificated in any category.

Required as indicated, unless accomplished previously. To prevent inadvertent excursions outside the normal flight envelope by ensuring that the flight crew is advised of appropriate procedures to follow in the event of lost or erroneous airspeed indications, accomplish the following: Revision of Airplane Flight Manual (AFM) (a) Within 10 days after the effective date of this AD, revise the “Procedures Following Failure” of Section 4 of the FAA-approved AFM to include the following information. This may be accomplished by inserting a copy of this AD into the AFM. “In the event of erroneous airspeed in flight or at take-off, or if the airspeed indication is lost, accomplish the following: Unreliable Airspeed Note: Unreliable airspeed may be caused by a radome destruction or obstructed pitots. If the failure is due to radome destruction, the drag will be increased and therefore N1 must be increased by 3% in cruise or 1.5% in approach. Switch OFF the AP/FD and A/THR Maintain flaps/slats in current configuration Check that speedbrakes are retracted When airborne, select landing gear up • With slats extended—Apply MCT thrust and set the pitch attitude to 12.5° • In clean configuration—Apply CLB thrust • When below FL100, set the pitch attitude to 10° • When above FL100, set the pitch attitude to 5° Note: Respect Stall warning if in alternate law When the flight path is stabilized, set the PROBE WINDOW HEAT to ON. Adjust pitch attitude and thrust regarding flight phase and aircraft configuration to obtain and maintain target speed. In the event of a double pitot probe heat failure, accomplish the following: Double Probe Heat Failure If icing conditions cannot be avoided: Switch OFF one of the affected ADRs” Note 1: The procedures identified in paragraph (a) of this AD have been introduced into the A330 AFM by the manufacturer at the revision levels listed below.   Airplane model Revision number A330-202 04 A330-223 04 A330-243 03 A330-301 05 A330-321 04 A330-322 04 A330-323 03 A330-341 04 A330-342 04 A330-343 03 Note 2: When the information in paragraph (a) of this AD has been incorporated into the FAA-approved general revisions of the AFM, the general revisions may be incorporated into the AFM, provided the information in this AD and the general revisions is identical. This AD may then be removed from the AFM. Alternative Methods of Compliance (b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA. Operators shall submit their requests through an appropriate FAA Principal Operations Inspector, who may add comments and then send it to the Manager, International Branch, ANM-116. Note 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the International Branch, ANM-116. Special Flight Permits (c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished. Note 4: The subject of this AD is addressed in French airworthiness directives 2001-068(B) and 2001-069(B), both dated February 21, 2001. Effective Date (d) This amendment becomes effective on July 12, 2001. Issued in Renton, Washington, on June 20, 2001. Kalene C.
