EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2011-0138 

Date: 20 July 2011 

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with 

Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and 

of the European third countries that participate in the activities of EASA under Article 66 of that 

Regulation.

This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the 

continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate 

an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency 

[EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption]. 

Type Approval Holder’s Name : 

AIRBUS

Type/Model designation(s) : 

A330 and A340 aeroplanes 

TCDS Number : EASA.A.004, EASA.A.015 

Foreign AD : Not applicable 

Supersedure : This AD supersedes EASA AD 2009-0202R1 dated 15 April 2010. 

ATA 34 Navigation – Pitot Probe Quick-Disconnect Union – Torque Check 

Manufacturer(s): Airbus ( formerly AIRBUS INDUSTRIE) 

Applicability: Airbus A330-201, A330-202, A330-203, A330-223, A330-223F, A330-243, -

A330-243F, A330-301, A330-302, A330-303, A330-321, A330-322, A330-323, 

A330-341, A330-342 and A330-343 aeroplanes, all manufacturer serial 

numbers, 

Airbus A340-211, A340-212, A340-213, A340-311, A340-312, A340-313, 

A340-541, A340-542, A340-642 and A340-643 aeroplanes, all manufacturer 

serial numbers, 

if fitted with Goodrich Pitot Probes Part Number (P/N) 0851HL, having serial 

numbers (s/n) 267328 through 270714 inclusive. 

Reason: Several reports have recently been received of loose pneumatic quickdisconnect unions on Goodrich pitot probes P/N 0851HL. These may be the 

result of mis-torque of the affected unions at equipment manufacturing level. 

Investigations are still on-going to determine the root cause(s). 

This condition, if not corrected, could lead to an air leak, resulting in incorrect 

total pressure measurement and consequent erroneous Calibrated Airspeed 

(CAS)/MACH parameters delivered by the Air Data Computer (ADC). 

As a precautionary measure, EASA issued Emergency AD 2009-0202 to 

require a torque check of the pneumatic quick-disconnect union on certain 

Goodrich P/N 0851HL pitot probes and corrective action, depending on 

findings. 

EASA AD 2009-0202-E was subsequently republished to remove an 

erroneous reference to Appendix A from the Reason section, as no Appendix 

was attached to this AD. AD 2009-0202 was later revised to exclude pitot

probes marked with a red torque check-mark from the torque-check required 

by paragraph (2.1) of this AD. 

This AD retains the requirements of EASA AD 2009-0202R1, which is 

superseded, and expands the Applicability to include the newly certified Model 

A330-223F and Model A330-243F aeroplanes. 

Effective Date: 03 August 2011 

Required Action(s) 

and Compliance 

Time(s): 

Required as indicated, unless accomplished previously: 

(1) For all aeroplanes identified in the Applicability section of this AD, 

except A330-223F and A330-243F aeroplanes,

(1.1) Within 5 days after 23 September 2009 [the effective date of EASA 

AD 2009-0202 at original issue], perform a torque check of the 

pneumatic quick-disconnect union of each Goodrich P/N 0851HL 

pitot probe, identified by s/n in the Applicability section of this AD, 

and depending on findings, before next flight, apply the associated 

corrective action in accordance with instructions defined in Airbus 

All Operators Telex (AOT) A330-34A3235 Revision 01 or AOT 

A340-34A4241 Revision 01 or AOT A340-34A5074 Revision 01, 

as applicable to aeroplane model. 

(1.2) Within 10 days after accomplishment of the torque check as 

required by paragraph (1.1) of this AD, report the results, including 

no findings, to Airbus. 

(1.3) A torque check of the pneumatic quick-disconnect union, 

accomplished before 23 September 2009, in accordance with the 

instructions of Airbus AOT A330-34A3235 at Original issue or AOT 

A340-34A4241 at Original issue or AOT A340-34A5074 at Original 

issue, as applicable to aeroplane model, is considered acceptable 

for compliance with the requirements of paragraph (1.1) of this AD. 

(2) For all aeroplanes identified in the Applicability section of this AD :

(2.1) After 23 September 2009, each time when a P/N 0851HL pitot 

probe, identified by s/n in the Applicability section of this AD, is 

installed on an aeroplane, before next flight after installation, 

perform the torque-check in accordance with the requirements of 

paragraph (1.1) of this AD. 

(2.2) Torque checks as specified in paragraph (2.1) of this AD are no 

longer required if an intact red torque check mark is visible across 

the interface of the pneumatic quick disconnect union and the 

union mount.
