Airworthiness Directive · Amendment 39-16988 · Navigation
Airbus Airplanes
This AD applies to the Airbus airplanes identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD; certificated in any category; all manufacturer serial numbers; with pitot probes having Goodrich part number (P/N) 0851HL, serial numbers 267328 through 270714 inclusive.
(1) Model A330-201, -202, -203, -223, -223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes.
(2) Model A340-211, -212, -213, -311, -312, and -313 airplanes.
(3) Model A340-541 and -642 airplanes.
We are superseding an existing airworthiness directive (AD) for certain Model A330-200 and -300 series airplanes, and Model A340- 200, -300, -500, and -600 series airplanes. This AD was prompted by reports of loose pneumatic quick-disconnect unions on Goodrich pitot probes that might be the result of mis-torque of the affected unions at equipment manufacturing level. This AD adds airplanes to the AD applicability. We are issuing this AD to detect and correct loose unions on the pitot probes, which could lead to an air leak, resulting in incorrect total pressure measurement and consequent erroneous calibrated airspeed (CAS)/MACH parameters delivered to the flightcrew by the air data computer.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For all airplanes except Model A330-223F and -243F airplanes: At the time specified, do the following actions.
(1) Within 14 days after September 22, 2010 (the effective date of AD 2010-17-02, Amendment 39-16392 (75 FR 50871, August 18, 2010)): Perform a torque check of the pneumatic quick-disconnect union of each pitot probe having Goodrich P/N 0851HL, serial numbers 267328 through 270714 inclusive, to determine if the torque is adequate, in accordance with the instructions of the applicable service information specified in table 1 of this AD. Before further flight, do all applicable corrective actions in accordance with the instructions of the applicable service information specified in table 1 of this AD.
