Amendment 39-16513; AD 2010-23-23

Airworthiness Directives; Eurocopter France (ECF) Model SA330F,

G, and J; and AS332C, L, L1, and L2 Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a new airworthiness directive (AD) for the specified ECF model helicopters. This AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European

Aviation Safety Agency (EASA), which is the Technical Agent for the

Member States of the European Community. The MCAI AD states that EASA received a report of a rear hinged door on a Model AS332L1 helicopter opening in flight without loss of the door. Examinations revealed incorrect positioning of a door catch that resulted in incorrect locking and uncontrolled opening of the door. This condition, if not detected and corrected, can lead to the loss of the hinged door in flight, damage to the main or tail rotor blades, and subsequent loss of control of the helicopter.

DATES: This AD becomes effective on December 22, 2010.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of December 22, 2010.

ADDRESSES: You may examine the AD docket on the Internet at http:// regulations.gov or in person at the Docket Operations office, U.S.

Department of Transportation, M-30, West Building Ground Floor, Room

W12-140, 1200 New Jersey Avenue, SE., Washington, DC between 9 a.m. and 5 p.m. Monday through Friday, except Federal holidays.

SUPPLEMENTARY INFORMATION:

Discussion

We issued an NPRM to amend 14 CFR part 39 to include an AD that would apply to the specified ECF model helicopters on June 11, 2010.

That NPRM was published in the Federal Register on July 7, 2010 (75 FR 38956). That NPRM proposed to require:

Within the next 220 hours time-in-service (TIS) or 6 months, whichever occurs first, inspecting the positioning of each lower and upper door catch; and

If any door catch is improperly installed, before further flight, replacing the affected catch, adjusting the micro-switches, and doing a functional test of the hinged door indicating system.

Comments

By publishing the NPRM, we gave the public an opportunity to participate in developing this AD. However, we received no comment on the NPRM or on our determination of the cost to the public. Therefore, based on our review and evaluation of the available data, we have determined that air safety and the public interest require adopting the

AD as proposed.

Related Service Information

ECF has issued Alert Service Bulletin (ASB) No. 52.13 for the

SA330F, G, and J helicopters, and 52.00.38 for the AS332C, C1, L, L1, and L2 helicopters, both ASBs dated December 1, 2008. The ASBs specify inspecting the upper and lower catches of the hinged doors to ensure the catches are correctly positioned. The actions described in the MCAI

AD are intended to correct the unsafe condition identified in the service information. The AS332C1 is not type certificated in the United

States.

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 Agent, has notified us of the unsafe condition described in the MCAI AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs.

Differences Between This AD and the MCAI AD

We refer to flight hours as hours TIS. This AD does not apply to the Model AS332C1 because that model is not FAA type certificated.

Costs of Compliance

We estimate that this AD will affect about 10 helicopters of U.S. registry. We also estimate that it will take about 2 work-hours per helicopter to inspect each door catch for correct position of the door hinges, replace an affected

Page 70105

catch, adjust the micro-switches of the hinged door, and do a functional test. The average labor rate is $85 per work-hour. The cost of the required parts is minimal. Based on these figures, we estimate that the cost of this AD on U.S. operators is $1,700.

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 have 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 that the 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); 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 an economic evaluation of the estimated costs to comply with this AD. See the AD docket to examine the economic evaluation.

Adoption of the Amendment 0

Accordingly, pursuant to the authority delegated to me by the

Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (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 adding the following new AD: 2010-23-23 Eurocopter France: Amendment 39-16513; Docket No. FAA- 2010-0670; Directorate Identifier 2009-SW-42-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective on

December 22, 2010.

Other Affected ADs

(b) None.

Applicability

(c) This AD applies to Model SA330F, G, J, and AS332C, L, L1, and L2 helicopters, certificated in any category.

Reason

(d) The mandatory continuing airworthiness information (MCAI) AD states that EASA received a report of a rear hinged door on a Model

AS332L1 helicopter opening in flight without loss of the door.

Examinations revealed incorrect positioning of a door catch that resulted in incorrect locking and uncontrolled opening of the door.

This condition, if not detected and corrected, can lead to the loss of the hinged door in flight, damage to the main or tail rotor blades, and subsequent loss of control of the helicopter.

Actions and Compliance

(e) Required as indicated:

(1) Within the next 220 hours time-in-service (TIS) or 6 months, whichever occurs first, unless done previously, inspect the position of each upper and lower door catch:

(i) As depicted in Figures 1 through 4 and by following the

Accomplishment Instructions, Table 1 of paragraph 2.B.2., of Alert

Service Bulletin (ASB) No. 52.13, dated December 1, 2008 (ASB 52.13) for the Model SA330F, G, and J helicopters, or

(ii) As depicted in Figures 1 through 5 and by following the

Accomplishment Instructions, Table 1 of paragraph 2.B.2. of ASB No. 52.00.38, dated December 1, 2008 (ASB 52.00.38) for the Model

AS332C, L, L1, and L2 helicopters.

(2) Before further flight, replace each improperly positioned catch by following the Accomplishment Instructions, paragraphs 2.B.3. and 2.B.4., of ASB 52.13 or ASB 52.00.38, as appropriate for your model helicopter.

(3) Before further flight, adjust each micro-switch, and conduct a functional test of the hinged-door indicating system:

(i) By following the Accomplishment Instructions, paragraph 2.B.5. and 2.B.6., of ASB 52.13, for the Model SA330F, G, and J helicopters, or

(ii) By following the Accomplishment Instructions, paragraph 2.B.5.a. through 2.B.5.b. of ASB 52.00.38 for the Model AS332C, L,

L1, and L2 helicopters.

Differences Between This AD and the MCAI AD

(f) We refer to flight hours as hours TIS. This AD does not apply to the Model AS332C1 because that model is not FAA type certificated.
