[Docket No. FAA-2010-1045; Directorate Identifier 2010-NM-101-AD; 
Amendment 39-16809; AD 2011-19-04]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A318, A319, A320, and A321 
Series Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding an existing airworthiness directive (AD) 
that applies to the products listed above. This AD results from 
mandatory continuing airworthiness information (MCAI) originated by an 
aviation authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

    One case of elevator servo-control disconnection has been 
experienced on an aeroplane of the A320 family. Investigation has 
revealed that the failure occurred at the servo-control rod eye-end.
    Further to this finding, additional inspections have revealed 
cracking at the same location on a number of other servo-control rod 
eye-ends. In several cases, both actuators of the same elevator 
surface were affected. The root cause of the cracking has not yet 
been determined and tests are ongoing.
    A dual servo-control disconnection on the same elevator could 
result in an uncontrolled surface, the elevator surface being 
neither actuated nor damped, which could lead to reduced control of 
the aeroplane.
* * * * *
    We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective October 21, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 21, 
2011.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on November 8, 2010 (75 
FR 68548), and proposed to supersede AD 2009-17-04, Amendment 39-15995 
(74 FR 41611, August 18, 2009). That NPRM proposed to correct an unsafe 
condition for the specified products. The MCAI states:

    One case of elevator servo-control disconnection has been 
experienced on an aeroplane of the A320 family. Investigation has 
revealed that the failure occurred at the servo-control rod eye-end.
    Further to this finding, additional inspections have revealed 
cracking at the same location on a number of other servo-control rod 
eye-ends. In several cases, both actuators of the same elevator 
surface were affected. The root cause of the cracking has not yet 
been determined and tests are ongoing.
    A dual servo-control disconnection on the same elevator could 
result in an uncontrolled surface, the elevator surface being 
neither actuated nor damped, which could lead to reduced control of 
the aeroplane.
    To address this unsafe condition, EASA [The European Aviation 
Safety Agency] AD 2008-0149 [which corresponds to FAA AD 2009-17-04] 
was issued to require a one-time inspection of the elevator servo-
control rod eye-ends for aeroplanes which have accumulated more than 
10,000 total Flight-Cycles (FC) since aeroplane first flight and, in 
case of findings, the accomplishment of corrective actions. As a 
result of this one-time inspection campaign, a significant number of 
rod eye-ends have been found cracked. In addition, some cracks have 
been reported on rod eye-ends that had not yet accumulated the 
10,000 FC of the established threshold.
    For the reason described above, this [EASA] AD partially retains 
the initial inspection requirement of EASA AD 2008-0149, which is 
superseded, reduces the compliance time of the initial inspections 
and introduces a repetitive inspection program.

    The corrective actions include replacing any cracked rod eye-end 
with a serviceable unit and re-adjusting the elevator servo-control. 
You may obtain further information by examining the MCAI in the AD 
docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
and the FAA's response to each comment.

Support for NPRM

    US Airways stated that the NPRM (75 FR 68548, November 8, 2010) 
will help prevent a possible dual servo control disconnection on the 
same elevator, which would result in an uncontrolled surface.

Request To Change Compliance Time

    Delta Air Lines (Delta) recommended that paragraph (g) of the NPRM 
(75 FR 68548, November 8, 2010) be simplified to accept the compliance 
specified in Airbus Mandatory Service Bulletin A320-27A1186, Revision 
05, dated March 10, 2010. Delta stated that the current NPRM wording is 
difficult to correlate between service bulletin instructions and the 
wording of the AD, and as written, it appears the operators are 
responsible for compliance to both the FAA AD wording and the service 
bulletin wording. Delta also stated that the FAA AD wording does not 
give acceptance to the compliance times for OPTION 2 specified in the 
tables on pages 22 and 23 of Airbus Mandatory Service Bulletin A320-
27A186, Revision 05, dated March 10, 2010. Delta stated it has used 
both options that are allowed under Airbus All Operators Telex (AOT) 
A320-27A1186 Revision 04, dated April 3, 2009.
    We disagree with the request to revise the compliance time 
specified in paragraph (g) of this AD. This AD allows incorporation of 
Task 271186-832-803-001, referenced as OPTION 2 in Airbus Mandatory 
Service Bulletin A320-27A1186, Revision 05, dated March 10, 2010, as a 
method for doing the inspection of inboard and outboard servo control 
rod eye-ends required by this AD; however, the task must be done at the 
compliance time mandated in this AD. In developing an appropriate 
compliance time for paragraph (g) of this AD, we considered the safety 
issues as well as the recommendations of EASA. Delta agreed with the 
FAA position during a teleconference on June 17, 2011. We have not 
changed the AD in this regard.

Request To Use New Revision of Service Information

    Delta requested that we allow Airbus Mandatory Service Bulletin 
A320-27A1186, Revision 06, dated December 14, 2010, as an acceptable 
means of compliance with the NPRM (75 FR 68548, November 8, 2010).
    We agree. In addition, we have received Airbus Mandatory Service 
Bulletin A320-27A1186, Revision 07, dated March 2, 2011. We have 
revised paragraphs (g), (h), (j), and (m), in this final rule to 
reference Airbus Mandatory

[[Page 57631]]

Service Bulletin A320-27A1186, Revision 07, dated March 2, 2011. We 
have also added table 2 of this AD to provide credit for certain 
actions done before the effective date of this AD in accordance with 
the Accomplishment Instructions of Airbus Mandatory Service Bulletin 
A320-27A1186, Revision 05, dated March 10, 2010, which was cited in the 
NPRM (75 FR 68548, November 8, 2010) as the appropriate source of 
service information; and Airbus Mandatory Service Bulletin A320-
27A1186, Revision 06, dated December 14, 2010.

Request To Provide Clearer Service Information or Allow Deviation From 
the Service Information Without an Alternative Methods of Compliance 
(AMOCs) Request

    Delta stated that Airbus Mandatory Service Bulletin A320-27A1186, 
Revision 05, dated March 10, 2010, as written, is confusing and 
difficult to comply with. Delta stated that it is poorly written for 
actual maintenance usage and it intermixes tasks that are accomplished 
on-wing with tasks that are performed in the shop environment. This 
makes literal compliance with Airbus Mandatory Service Bulletin A320-
27A1186, Revision 05, dated March 10, 2010 (and thus the AD) difficult 
and unnecessarily places the operator at risk of non-compliance. To 
support its position, this commenter mentioned that, for example, the 
instructions in Figure A-FBEAA of Airbus Mandatory Service Bulletin 
A320-27A1186, Revision 05, dated March 10, 2010, for re-installing the 
crack-free rod-end using the same number of turns previously recorded 
when the rod-end was removed is meaningless as the rod-end will be 
installed on a different aircraft, and the number of turns most likely 
will be different in order to maintain aircraft rig on the new 
airplane. Delta wanted us to provide clearer language within the 
service information or allow operators to deviate from Airbus Mandatory 
Service Bulletin A320-27A1186, Revision 05, dated March 10, 2010, as 
written such that the operator can perform the required work without 
requesting an AMOC.
    We disagree with the request. The example given in Figure A-FBEAA 
of Airbus Mandatory Service Bulletin A320-27A1186, Revision 05, dated 
March 10, 2010, for re-installing the crack-free rod-end specifies 
installation of a spare rod eye-end using the same number of turns 
previously recorded when the rod eye-end was removed. Therefore 
recording and re-installing using the same number of turns is 
necessary. We conclude that the service information is adequate and we 
have not changed this AD in this regard. However, under the provisions 
of paragraph (l) of this AD, we will consider requests for approval of 
an AMOC if sufficient data are submitted to substantiate that a 
deviation from the service information would provide an acceptable 
level of safety.

Requests To Remove Reporting Requirements

    Delta, US Airways, and Airbus request the removal of the reporting 
requirement of paragraph (g)(3) of the NPRM (75 FR 68548, November 8, 
2010) because Airbus has announced that it is no longer using the 
reported data to form a technical solution.
    Because Airbus no longer needs the reported data to form a 
technical solution, we agree it is not necessary for operators to 
submit a report of inspection findings. We have removed paragraphs 
(g)(3) and (l)(3) of this AD.

Request To Change Servo Repetitive Inspection Initial Compliance Time

    Delta requested we add a statement regarding the servos (and the 
associated rod-end) that are replaced for failure prior to the 10,000 
flight-cycle threshold be placed on the repetitive 5,000 flight-cycle 
period rather than the ``first'' inspection period after the aircraft 
reached the 10,000 flight-cycle initial level. Delta stated that the 
NPRM (75 FR 68548, November 8, 2010) would require the inspection be 
delayed for aircraft under/less than the 10,000 flight-cycle threshold. 
Delta stated as the servo ``mean time between removals'' is currently 
about 11,000 flight hours, it makes little sense to inspect a 
replacement rod-end only a few hundred or 1,000 flight cycles after 
installation. Delta stated it makes sense to apply the 5,000 flight-
cycle limit to the rod-end on the replaced servo.
    We disagree. If the servos are replaced before accumulating 10,000 
total airplane flight cycles as of September 22, 2009 (the effective 
date of AD 2009-17-04, Amendment 39-15995 (74 FR 41611, August 18, 
2009)), then the first inspection in accordance with paragraph (g)(2) 
of this AD is required at the later of the times specified in 
paragraphs (g)(2)(ii)(A) and (g)(2)(ii)(B), i.e., before the airplane 
accumulates 7,500 total flight cycles, or within 40 months after the 
effective date of this AD, whichever occurs later, but no later than 
13,000 total flight cycles on the airplane, followed by repeat 
inspection in accordance with paragraph (h) of this AD. Therefore, no 
foreseeable scenario can necessitate an inspection after a few hundred 
or 1,000 airplane flight cycles. We have not changed this AD in this 
regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously. We also determined that 
these changes will not increase the economic burden on any operator or 
increase the scope of the AD.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a Note within the AD.

Costs of Compliance

    We estimate that this AD will affect about 770 products of U.S. 
registry.
    The actions that are required by AD 2009-17-04, Amendment 39-15995 
(74 FR 41611, August 18, 2009), and retained in this AD, take about 13 
work-hours per product, at an average labor rate of $85 per work-hour. 
Based on these figures, the estimated cost of the currently required 
actions is $1,105 per product.
    We estimate that it will take about 12 work-hours per product to 
comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of these AD requirements to the U.S. operators to be $785,400, or 
$1,020 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with

[[Page 57632]]

promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify this AD:
    1. Is not a ''significant regulatory action'' under Executive Order 
12866;
    2. Is not a ''significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Amendment 39-15995 (74 FR 
41611, August 18, 2009) and adding the following new AD:

2011-19-04 Airbus: Amendment 39-16809. Docket No. FAA-2010-1045; 
Directorate Identifier 2010-NM-101-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective October 
21, 2011.

Affected ADs

    (b) This AD supersedes AD 2009-17-04, Amendment 39-15995 (74 FR 
41611, August 18, 2009).

Applicability

    (c) This AD applies to Airbus Model A318-111, -112, -121, and -
122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, 
and -133 airplanes; Model A320-111, -211, -212, -214, -231, -232, 
and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -
213, -231, and -232 airplanes; certificated in any category; all 
manufacturer serial numbers.

Subject

    (d) Air Transport Association (ATA) of America Code 27: Flight 
controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    One case of elevator servo-control disconnection has been 
experienced on an aeroplane of the A320 family. Investigation has 
revealed that the failure occurred at the servo-control rod eye-end.
    Further to this finding, additional inspections have revealed 
cracking at the same location on a number of other servo-control rod 
eye-ends. In several cases, both actuators of the same elevator 
surface were affected. The root cause of the cracking has not yet 
been determined and tests are ongoing.
    A dual servo-control disconnection on the same elevator could 
result in an uncontrolled surface, the elevator surface being 
neither actuated nor damped, which could lead to reduced control of 
the aeroplane.

FAA AD Differences

    Note 1:  This AD differs from the MCAI and/or service 
information as follows: No differences.

Other FAA AD Provisions

    (l) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, Transport Airplane Directorate, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Branch, send it to Attn: Sanjay
