Applicability*9
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.

Compliance
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Required actions
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. Table 1—Airbus Service Information Airbus all operators telex— Revision— Dated— A330-34A3235 (for Model A330-201, -202, -203, -223, -243, -301, -302, -303, -321,-322, -323, -341, -342, and -343 airplanes) 02 March 1, 2010. A340-34A4241 (for Model A340-211, -212, -213, -311, -312, and -313 airplanes) 02 March 1, 2010. A340-34A5074 (for Model A340-541 and -642 airplanes) 02 March 1, 2010. (2) Within 30 days after performing the torque check required by paragraph (g)(1) of this AD, or within 30 days after September 22, 2010 (the effective date of AD 2010-17-02, Amendment 39-16392 (75 FR 50871, August 18, 2010), whichever occurs later: Report the torque check results to Airbus, including no findings, as specified in the instructions of the applicable service information listed in table 1 of this AD. (3) This paragraph provides credit for the actions required by paragraph (g)(1) of this AD, if those actions were done before September 22, 2010 (the effective date of AD 2010-17-02, Amendment 39-16392 (75 FR 50871, August 18, 2010), using the applicable service information listed in table 2 of this AD. Table 2—Airbus Credit Service Information Airbus all operators telex— Revision— Dated— A330-34A3235 September 10, 2009. A330-34A3235 1 September 21, 2009. A340-34A4241 September 10, 2009. A340-34A4241 1 September 21, 2009. A340-34A5074 September 10, 2009. A340-34A5074 1 September 21, 2009. (4) As of September 22, 2010 (the effective date of AD 2010-17-02, Amendment 39-16392 (75 FR 50871, August 18, 2010), no person may install a pitot probe having Goodrich P/N 0851HL, serial numbers 267328 through 270714 inclusive, on any airplane, unless the actions required by paragraph (g)(1) of this AD have been done; or an intact red torque check mark is visible on the interface of the pneumatic quick disconnect union and the union mount.
Unsafe condition
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. 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 (ADC).
Affected ADs
This AD supersedes AD 2010-17-02, Amendment 39-16392 (75 FR 50871, August 18, 2010).

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
