[Docket No. FAA-2011-0939; Directorate Identifier 2010-SW-067-AD; 
Amendment 39 16798; AD 2011-18-16]
RIN 2120-AA64


Airworthiness Directives; Eurocopter France (Eurocopter) Model 
AS332C, AS332L, AS332L1, and AS332L2 Helicopters

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) for 
the specified Eurocopter model helicopters. This action requires 
inspecting the upper end fitting ball joints of the main rotor 
servocontrols for lateral play, and depending on the findings either 
repetitively inspecting the ball joint or replacing the servocontrol. 
This amendment is prompted by reports of noncompliant swaging of the 
end fitting ball joints on main rotor servocontrols. Investigation has 
shown that the swaging load applied to the ball joints was 1.3 metric 
tons instead of the specified 13 metric tons. The actions specified in 
this AD are intended to prevent failure of the upper end fitting ball 
joints of the main rotor servocontrols, failure of the upper end 
fittings, and loss of control of the helicopter.

DATES: Effective November 14, 2011.

SUPPLEMENTARY INFORMATION: 

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. 2010-0117-E, dated June 16, 2010, to correct an unsafe condition 
for the specified Eurocopter model helicopters. EASA advises that the 
equipment manufacturer (Goodrich) has identified two servocontrol 
production batches as noncompliant with swaging of the end fitting ball 
joints on main rotor servocontrols. EASA states that investigations 
have revealed that the swaging load applied to the ball joints in these 
two batches was 1.3 metric tons, instead of the specified 13 metric 
tons, which could lead the ball joints to slip in service. The slipping 
of the ball joint of the servocontrol lower end fitting does not 
significantly affect the service life of the end fitting. However, the 
slipping of the ball joint of the servocontrol upper end fitting can 
lead to a significant reduction in the service life of the end fitting. 
This condition, if not corrected, could lead to failure of the upper 
end fitting ball joint of a main rotor servocontrol and result in loss 
of control of the helicopter.

Differences Between This AD and the EASA AD

    We refer to flight hours as hours time-in-service (TIS).

Related Service Information

    Eurocopter has issued an Emergency Alert Service Bulletin (EASB), 
dated June 15, 2010, with two numbers: No. 67.00.40 for FAA type-
certificated Models AS332C, L, L1, and L2 and for Models AS332C1, B, 
B1, F1, M, and M1 that are not FAA type certificated, and No. 67.00.27 
for Models AS532AC, AL, SC, UC, UE, UL, A2, and U2 that are not FAA 
type certificated. The EASB specifies checking and restoring conformity 
of the affected end fitting ball joints of the servocontrols. The EASB 
contains Appendix 1 and 2, Goodrich Service Bulletins No. SC7203-67-31-
02 and No. SC7221-67-39-02, both dated May 11, 2010, which specify the 
process for comforming each affected servocontrol. EASA classified this 
EASB as mandatory and issued Emergency AD No. 2010-0117-E, dated June 
16, 2010, to ensure the continued airworthiness of these helicopters.

FAA's Evaluation and Unsafe Condition 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, their technical 
representative, has notified us of the unsafe condition described in 
the EASA AD. We are issuing this AD because we evaluated all 
information provided by EASA and determined the

[[Page 66607]]

unsafe condition exists and is likely to exist or develop on other 
helicopters of these same type designs.
    Eurocopter states that there are currently no helicopters with the 
affected part installed in the United States. However, this rule is 
necessary to ensure that the described unsafe condition is addressed in 
the event this part is installed on any helicopter in the future.

Costs of Compliance

    There are no costs of compliance assuming that there are no 
helicopters on the U.S. Registry with the affected part installed as 
represented by the manufacturer.

FAA's Determination of the Effective Date

    This unsafe condition is likely to exist or develop on other 
helicopters of these same type designs. Therefore, this AD is being 
issued to prevent failure of the upper end fitting ball joints of the 
main rotor servocontrols, failure of the upper end fittings, and loss 
of control of the helicopter. Since there are currently no U.S. 
registered helicopters with the affected part installed, we have 
determined that notice and opportunity for prior public comment before 
issuing this AD are unnecessary and that good cause exists for making 
this amendment effective in less than 30 days.

Requirements of This AD

    This AD requires:
    <bullet> Within 15 hours TIS, unless accomplished previously, using 
a feeler gage, measuring the lateral play between the outer ring of the 
ball joint and each of the two faces of the upper end fitting.
    <bullet> If the lateral play is greater than or equal to 1 
millimeter (MM) (0.04 inch) and the servocontrol has accumulated 825 or 
more hours TIS, replacing it with an airworthy servocontrol before 
further flight.
    <bullet> If the lateral play is greater than or equal to 1 mm (0.04 
inch) and the servocontrol has accumulated less than 825 hours TIS, on 
or before the servocontrol accumulates 825 hours TIS, replacing it with 
an airworthy servocontrol.
    <bullet> If the lateral play is less than 1 mm (0.04 inch), 
thereafter, at intervals not to exceed 300 hours TIS, repeating the 
inspection. At each 300-hour TIS inspection, if the lateral play is 
greater than or equal to 1 mm (0.04 inch), within 525 hours TIS, 
replacing the servocontrol with an airworthy servocontrol.
    <bullet> Replacing the servocontrol with an airworthy servocontrol 
that is not included in the AD applicability or that is modified with a 
letter ``R'' after the S/N constitutes terminating action for the 
requirements of this AD.
    Because these affected parts have an unlimited operational fatigue 
life with no previous fatigue inspections required, the replacement 
criteria of this AD assumes that the affected servocontrols found to 
have greater than or equal to 1 MM of lateral play have already been 
operated for at least 825 hours TIS with this fatigue damage and must 
be replaced at 825 hours TIS or if they have already accumulated 825 or 
more hours TIS, within 15 hours TIS of the effective date of this AD. 
However, if a subsequent 300-hour TIS repetitive inspection required by 
this AD reveals lateral play of 1 MM or greater, those affected 
servocontrols may be operated an additional 525 hours TIS because the 
previous 300-hours TIS inspection established the new baseline for the 
825 hours TIS thereby allowing an additional 525 hours TIS before 
replacement.

Comments Invited

    This AD is a final rule that involves requirements that affect 
flight safety and was not preceded by notice and an opportunity for 
public comment; however, we invite you to submit any written data, 
views, or arguments regarding this AD. Send your comments to an address 
listed under ADDRESSES. Include FAA Docket No. ``FAA-2011-0939; 
Directorate Identifier 2010-SW-067-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the AD. We will consider 
all comments received by the closing date and may amend the AD in light 
of those comments.
    We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact 
with FAA personnel concerning this AD. Using the search function of the 
docket Web site, you can find and read the comments to any of our 
dockets, including the name of the individual who sent the comment. You 
may review the DOT's complete Privacy Act Statement in the Federal 
Register published on April 11, 2000 (65 FR 19477 78).

Regulatory Findings

    We have determined that notice and prior public comment are 
unnecessary in promulgating this regulation; therefore, it can be 
issued immediately to correct an unsafe condition in aircraft because 
none of the model helicopters that are registered in the United States 
have the affected part installed. We have also determined that this 
regulation is not a ``significant regulatory action'' under Executive 
Order 12866. It has been determined further that this action involves 
an emergency regulation under DOT Regulatory Policies and Procedures 
(44 FR 11034, February 26, 1979). If it is determined that this 
emergency regulation otherwise would be significant under DOT 
Regulatory Policies and Procedures, a final regulatory evaluation will 
be prepared and placed in the AD docket.

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 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.

(AD) to read as follows:

    2011-18-16 Eurocopter France: Amendment 39-16798; Docket No. FAA 
2011-0939; Directorate Identifier 2010-SW-067-AD.


[[Page 66608]]


    Applicability: Models AS332C, L, L1, and L2 helicopters, with 
main rotor servocontrols, part number (P/N) SC7203-1 with serial 
number (S/N) 633 through 643, 645 through 659, 664 or 665, or P/N 
SC7221-1 with S/N 1693 through 1723 and 1726 or 1727, which are not 
marked with a letter ``R'' after the S/N, certificated in any 
category.
    Compliance: Required as indicated.
    To prevent failure of the upper end fitting ball joints of the 
main rotor servocontrols, failure of the upper end fittings, and 
loss of control of the helicopter, do the following:
    (a) Within 15 hours time-in-service (TIS), unless accomplished 
previously, using a feeler gage, measure the lateral play between 
the outer ring of the ball joint and each of the two faces of the 
upper end fitting as depicted in Figure 1 of this AD.
[GRAPHIC] [TIFF OMITTED] TR27OC11.001

    (b) If the lateral play is greater than or equal to 1 millimeter 
(MM) (0.04 inch) and the servocontrol has accumulated 825 or more 
hours TIS, before further flight, replace it with an airworthy 
servocontrol.
    (c) If the lateral play is greater than or equal to 1 mm (0.04 
inch) and the servocontrol has accumulated less than 825 hours TIS, 
on or before the servocontrol accumulates 825 hours TIS, replace it 
with an airworthy servocontrol.
    (d) If the lateral play is less than 1 mm (0.04 inch), at 
intervals not to exceed 300 hours TIS, repeat the inspection 
required by paragraph (a) of this AD. At each 300 hour TIS interval 
inspection, if the lateral play is greater than or equal to 1 mm 
(0.04 inch), within 525 hours TIS, replace the servocontrol with an 
airworthy servocontrol.

    Note 1:  An acceptable method of returning the servocontrol to 
an airworthy condition

[[Page 66609]]

for the purposes of this AD is by modifying the servocontrol and 
marking an ``R'' after the S/N by following Goodrich Service 
Bulletin (SB) No. SC7203-67-31-02, dated May 11, 2010, for 
servocontrol, P/N SC7203-1, or Goodrich SB No. SC72216739-02, dated 
May 11, 2010, for servocontrol, P/N SC7221 1. The Goodrich SBs are 
attached to Eurocopter Emergency Alert SB containing two numbers 
(67.00.40 and 67-00.27), dated June 15, 2010 as Appendix 1 and 
Appendix 2, respectively. None of these three SBs is incorporated by 
reference in this AD.

    (e) Replacing a servocontrol with an airworthy servocontrol that 
is marked with a letter ``R'' by the manufacturer after the S/N 
constitutes terminating action for the requirements of this AD.
    (f) To request a different method of compliance or a different 
compliance time for this AD, follow the procedures in 14 CFR 39.19.
