RIN 2120-AA64


Airworthiness Directives; Eurocopter France Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Eurocopter France (Eurocopter) Model AS332C, AS332L, AS332L1, 
AS332L2, and SA330J helicopters. This proposed AD would require 
inspecting the crimping of the ball joint of the upper- and lower- end-
fittings of the main servo-control and, depending on findings, 
replacing the main servo-control or repairing the ball joint. This 
proposed AD is prompted by incidents of missing crimping on the ball 
joints of servo-control end-fittings. The proposed actions are intended 
to prevent failure of a main servo-control upper end fitting, and 
subsequent failure of the flight controls and loss of control of the 
helicopter.

DATES: We must receive comments on this proposed AD by October 21, 
2013.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your 
comments electronically.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
No. 2012-0248, dated November 20, 2012, to correct an unsafe condition 
for Eurocopter AS 332 C, AS 332 C1, AS 332 L, AS 332 L1, AS 332 L2, and 
SA 330 J helicopters with certain part-numbered main servo-controls 
installed. EASA advises that several occurrences were reported to 
Eurocopter of missing crimping on ball joints of servo-control end-
fittings. EASA states that while slipping of the ball joint of the 
lower end-fitting does not affect its service life, slipping of the 
ball joint of the upper end-fitting can lead to a significant reduction 
of the service life of this end-fitting. As a result, the EASA AD 
requires inspecting each ball joint for crimping and, depending on the 
findings, replacing the main servo-control.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition is likely 
to exist or develop on other products of the same type design.

Related Service Information

    Eurocopter issued one Emergency Alert Service Bulletin (EASB) with 
three different numbers, all Revision 1, and all dated December 5, 
2012. EASB No. 67.00.45 applies to civilian Model AS332C, AS332C1, 
AS332L, AS332L1, AS332L2, and military Model AS332B, AS332B1, AS332M, 
AS332M1, and AS332F1 helicopters. EASB No. 67.00.31 applies to military 
Model AS532AC, AS532AL, AS532SC, AS532UC, AS532UE, AS532UL, AS532A2, 
and AS532U2 helicopters. EASB No. 67.19 applies to civilian Model 
SA330J and military Model SA330Ba, SA330Ca, SA330Ea, SA330L, SA330Jm, 
SA330S1, and SA330Sm helicopters. The EASB specifies visually checking 
for crimping of the ball joints of the upper- and lower- servo control 
end-fittings and informing the Eurocopter Technical Support Department 
of any ball joint that is not crimped. For an upper end-fitting ball 
joint that is not crimped and slips one millimeter (mm) or greater, the 
EASB specifies returning the servo-control for replacement of the ball 
joint and the end-fitting. For an upper end-fitting ball joint that is 
not crimped and slips less than one mm, the EASB specifies either 
crimping the ball joint or returning the servo-control for ball joint 
crimping. For a lower end-fitting ball joint that is not crimped, the 
EASB states to crimp the ball joint. The EASB also states that if a 
ball joint is crimped, no action on that ball joint is required in 
regard to this unsafe condition.

Proposed AD Requirements

    This proposed AD would require visually inspecting the applicable 
ball joint of the upper and lower end-fittings of the main servo 
control for crimping. If the ball joint of the upper end-fitting is not 
crimped and the slipping of the ball joint is one mm or greater, then 
this proposed AD would require replacing the servo-control with an 
airworthy servo-control. If the ball joint of the upper end-fitting is 
not crimped and the slipping of the ball joint is less than one mm, 
then this proposed AD would require replacing the servo-control with an 
airworthy servo-control or crimping the ball joint. If the ball joint 
of the lower end-fitting is not crimped, this proposed AD would require 
crimping the ball joint.

Costs of Compliance

    We estimate that this proposed AD would affect 18 helicopters of 
U.S. Registry. We estimate that operators may incur the following costs 
in order to comply with this AD. We estimate it would take 1 work-hour 
to inspect the ball joint for crimping at an average labor cost of $85 
per work-hour. Based on these figures, it would cost about $85 per 
helicopter for the inspection, or $1,530 for U.S. operators. We 
estimate it would take 4 work-hours to replace a servo-control and 
parts would cost approximately $60,358 for a total estimated cost of 
$60,698 for replacement.
    According to Eurocopter's service information some of the costs of 
this proposed AD may be covered under warranty, thereby reducing the 
cost impact on affected individuals. We do not control warranty 
coverage by

[[Page 51117]]

Eurocopter or UTC Actuation Systems/Goodrich Actuation Systems. 
Accordingly, we have included all costs in our cost estimate.

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 
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 proposed 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation:
    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);
    3. Will not affect intrastate aviation in Alaska to the extent that 
it justifies making a regulatory distinction; and
    4. 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 an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.

(b) Unsafe Condition

    This AD defines the unsafe condition as missing crimping on a 
ball joint of a main servo-control end-fitting. This condition could 
result in failure of a main servo-control upper end fitting, failure 
of the flight controls, and loss of control of the helicopter.

end-fitting of the main servo control for crimping in accordance 
with Detail A and Detail B, Figure 1, of the EASB applicable to your 
model helicopter.
    (A) If the upper ball joint is not crimped and the ball joint 
slips a distance of 1 millimeter (mm) or greater, replace the servo-
control with an airworthy servo-control.
    (B) If the upper ball joint is not crimped and the ball joint 
slips a distance of less than 1mm, either crimp the ball joint or 
replace the servo-control with an airworthy servo-control.

end-fitting of the main servo-control for crimping in accordance 
with Detail A and Detail B, Figure 1, of the EASB applicable to your 
model helicopter. If the lower ball joint is not crimped, crimp the 
ball joint.
    (2) Prior to installing any servo-control that is affected by 
this AD, perform the required actions in accordance with paragraphs 
(e)(1) of this AD.
