AD 2011-03-02

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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:

While adjusting the position of the pedal unit on a SA 330 helicopter, the copilot set the position beyond the end limit (``tall pilot'' position). This resulted in the separation of the pedal adjustment system and the pedals rocking forward.
After investigation, it was determined that the Loctite bond on the ``tall pilot'' stop nut was damaged, most likely due to aging of the adhesive. The nut came loose and could no longer perform its stop function. The threaded rod of the adjustment system separated from the system.
The separation of the adjustment system, if not corrected, could result in the loss of control of the pedal units, causing the helicopter to begin rotating.

We are issuing this AD to require actions to correct the unsafe condition on these products.

Final rule.

2011-03-02 EUROCOPTER FRANCE: Amendment 39-16585; Docket No. FAA- 2010-0891; Directorate Identifier 2009-SW-055-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective April 14, 2011.

Affected ADs

(b) None.

Applicability

(c) This AD applies to SA330F, SA330G, and SA330J helicopters, all serial numbers, certificated in any category, equipped with pedal position adjustment system modification (MOD 07.10.304).

Subject

(d) Air Transport Association of America (ATA) Code 67: Rotors Flight Control.

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:
While adjusting the position of the pedal unit on a SA 330 helicopter, the copilot set the position beyond the end limit (``tall pilot'' position). This resulted in the separation of the pedal adjustment system and the pedals rocking forward.
After investigation, it was determined that the Loctite bond on the ``tall pilot'' stop nut was damaged, most likely due to aging of the adhesive. The nut came loose and could no longer perform its stop function. The threaded rod of the adjustment system separated from the system.
The separation of the adjustment system, if not corrected, could result in the loss of control of the pedal units, causing the helicopter to begin rotating.
For the reasons described above, this Emergency AD requires a one-time functional test and modification (MOD 330A779820.00) of the pedal unit adjustment system.

Actions and Compliance

(f) Unless already done, do the following actions:
(1) Within the next 10 hours time-in-service after April 14, 2011 (the effective date of this AD), do a functional test of the pedal unit adjustment system following paragraph 2.B.1 of EUROCOPTER Emergency Alert Service Bulletin No. 67.18, dated August 3, 2009.
(2) If any non-conformity is found, before further flight, modify the pedal unit adjustment system following paragraphs 2.B.2, 2.B.3 or 2.B.4, and 2.B.5 of EUROCOPTER Emergency Alert Service Bulletin No. 67.18, dated August 3, 2009 (MOD 330A779820.00).
(3) If any non-conformity is not found, within 3 months after April 14, 2011 (the effective date of this AD), modify the pedal unit adjustment system following paragraphs 2.B.2, 2.B.3, and 2.B.5 of the EUROCOPTER Emergency Alert Service Bulletin No. 67.18, dated August 3, 2009 (MOD 330A779820.00).
(4) If half-bushings are not available when complying with paragraph (f)(2) or (f)(3) of this AD, flights are authorized without half-bushings for up to 12 months after April 14, 2011 (the effective date of this AD).
(5) After 3 months after April 14, 2011 (the effective date of this AD), do not install a pedal position adjustment system, unless it has been modified (MOD 330A779820.00) in accordance with the requirements of this AD.

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 September 13, 2010 (75 FR 55492). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

While adjusting the position of the pedal unit on a SA 330 helicopter, the copilot set the position beyond the end limit (``tall pilot'' position). This resulted in the separation of the pedal adjustment system and the pedals rocking forward.
After investigation, it was determined that the Loctite bond on the ``tall pilot'' stop nut was damaged, most likely due to aging of the adhesive. The nut came loose and could no longer perform its stop function. The threaded rod of the adjustment system separated from the system.
The separation of the adjustment system, if not corrected, could result in the loss of control of the pedal units, causing the helicopter to begin rotating.
For the reasons described above, this Emergency AD requires a one-time functional test and modification (MOD 330A779820.00) of the pedal unit adjustment system.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed.

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 MCAIand related service information.
We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD.

Costs of Compliance

We estimate that this AD will affect 6 products of U.S. registry. We also estimate that it will take about 3 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $100 per product.
Based on these figures, we estimate the cost of this AD to the U.S. operators to be $2,130 or $355 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 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) Isnot a ``significant rule'' under 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 http://www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
