Airworthiness Directive · Amendment 39-11769 · Airbus Model A319, A320, and A321 Series Airplanes
Airbus Model A319, A320, and A321 Series Airplanes
The following models, certificated in any category, excluding those on which Airbus Service Bulletin A320-27-1126, dated April 26, 1999 (for Model A319 and 321 series airplanes); or A320-27-1127, dated April 26, 1999, or Revision 01, dated October 6, 1999 (for Model A320 series airplanes); has been accomplished:
• Model A319 series airplanes, serial numbers (S/N) 0546 through 0972 inclusive;
• Model A320 series airplanes, S/N 0002 through 0842 inclusive, 0846 through 0859 inclusive, 0865, 0866, and 0872 through 0960 inclusive; and
• Model A321 series airplanes, S/N 0364 through 0974 inclusive.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319, A320, and A321 series airplanes, that requires a one-time general visual inspection to determine the part number and serial number of the spoiler servocontrol, and corrective action, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the spoiler servocontrol piston rod, which could result in reduced controllability of the airplane.
To prevent failure of the servocontrol piston rod, which could result in reduced controllability of the airplane, accomplish the following:
(a) At the applicable time specified by paragraph (a)(1) or (a)(2) of this AD: Perform a general visual inspection to determine the part number and serial number for the spoiler servocontrols, in accordance with Airbus Service Bulletin A320-27-1126, April 26, 1999, or Revision 01, dated October 6, 1999 (for Model A319 and A321 series airplanes); or Airbus Service Bulletin A320-27-1127, dated April 26, 1999, or Revision 01, dated October 6, 1999 (for Model A320 series airplanes); as applicable. If the part number and serial number are identified in paragraph 2.B.(1)(b) of the Accomplishment Instructions of the applicable service bulletin, prior to further flight, perform applicable corrective actions (including removal, reidentification of the servocontrol, and replacement of the servocontrol with a modified part) as specified in the applicable service bulletin.
(1) For Model A319 and A321 series airplanes: Inspect within 2 months after the effective date of this AD.
(2) For Model A320 series airplanes: Inspect within 28 months after the effective date of this AD.
Note 2: 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 under normally available lighting conditions such as daylight, hangar lighting, flashlight, or drop-light, 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.”
(b) As of the effective date of this AD, no person shall install on any airplane a spoiler servocontrol having part number 31077-050, 31077-060, or 31077-110; and S/N 0001 to 3499, except those serial numbers excluded in paragraph 2.B.(1)(b)1 of the Accomplishment Instructions in Airbus Service Bulletin A320-27-1126, dated April 26, 1999, or Revision 01, dated October 6, 1999; unless that servocontrol has been inspected, and corrective actions have been performed, in accordance with the requirements of this AD.
