Airworthiness Directive · Amendment 39-11001 · Airbus Model A320 Series Airplanes
Airbus Model A320 Series Airplanes
Model A320 series airplanes; serial numbers 002 through 008 inclusive, 010 through 014 inclusive, 016 through 078 inclusive, 080 through 104 inclusive, 106 through 363 inclusive, 365 through 384 inclusive, 386 through 411 inclusive, 413 through 433 inclusive, 435 through 457 inclusive, 459 through 467 inclusive, and 469 through 472 inclusive; except for airplanes on which Airbus Service Bulletin A320-29-1058, Revision 1, dated November 28, 1994, has been accomplished; certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A320 series airplanes, that currently requires modification of the trimmable horizontal stabilizer (THS). This amendment adds a requirement for a one-time inspection of the flexible hoses of the elevator return lines on the THS to detect installation of incorrect clamps, or missing clamps or bonding leads; and for replacement of the clamps or bonding leads with new parts, 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 leakage from hydraulic pipe fittings in the THS, which could result in failure of the THS and consequent reduced controllability of the airplane.
