Discussion

On May 8, 2013, at 78 FR 26712, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 to include an AD that would apply to Eurocopter Model EC 155B, EC155B1, SA–365N, SA–365N1, AS–365N2, AS 365 N3, and SA–366G1 helicopters, except helicopters with modification (MOD) 0767B5 installed. The NPRM proposed to require inspecting the collective pitch lever for correct unlocking with a spring scale, and if required, adjusting the collective pitch lever restraining tab and, for certain models, adjusting the collective link rods. The NPRM also proposed to require inspecting the collective pitch lever for the risk of inadvertent locking by measuring the clearance between the locking pin of the collective pitch lever and the L-section of the restraining tab, and if required, modifying the tab with a slight bend to the tab. The proposed requirements were intended to detect an incorrectly adjusted collective pitch lever, which could result in loss of control of the helicopter.

The NPRM was prompted by AD No. 2011–0154, dated August 22, 2011, issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union. EASA issued AD 2011–0154 to correct an unsafe condition for Eurocopter Model EC 155B, EC155B1, SA–365N, SA–365N1, AS–365N2, AS 365 N3, and SA–366G1 helicopters. EASA advises that two occurrences have been reported of inadvertent locking and unlocking of the collective pitch lever. One inadvertent collective pitch lever locking occurred when moving the collective pitch lever to the low-pitch position, and one inadvertent collective pitch lever unlocking occurred during engine start. To address this unsafe condition, Eurocopter issued AS 365 Alert Telex No. 67.00.10, SA 366 Alert Telex No. 67.05, and EC 155 Alert Telex No. 67A007, which describe procedures to inspect the collective pitch lever for correct locking and unlocking conditions. This inspection was


### 56600 Federal Register / Vol. 78, No. 178 / Friday, September 13, 2013 / Rules and Regulations

mandated by Direction Ge  ́ ne

 ́ rale de l’Aviation Civile (DGAC) France AD No. F–2005–127, dated July 20, 2005. DGAC subsequently revised its AD, No. F– 2005–127 R1, dated February 1, 2006 (DGAC AD F–2005–127 R1), after Eurocopter issued Alert Service Bulletins containing the same inspection procedures and bearing the same numbers as the Alert Telexes. Since the issuance of DGAC AD F– 2005–127 R1 Eurocopter developed an assembly comprised of a blade, a hinge, and a return spring to replace the flexible collective lever locking blade as terminating action for the inspection required by the AD. EASA then issued AD No. 2011–0154, which superseded DGAC AD F–2005–127 R1, retaining the inspection procedures for the collective pitch lever and removing from the applicability helicopters with the hinged, spring-loaded collective lever locking blade installed, designated as
MOD 0767B65.

Comments

We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM (78 FR 26712, May 8, 2013).

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 the EASA 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 and that air safety and the public interest require adopting the AD requirements as proposed.

Related Service Information

We reviewed Eurocopter Alert Service Bulletin (ASB) No. 67.00.10 for Model AS365 helicopters, ASB No. 67.05 for Model SA366 helicopters, and ASB No. 67A007 for Model EC155 helicopters. All three ASBs are Revision 1 and are dated February 25, 2009. These ASBs describe procedures for inspecting and adjusting the collective pitch lever for correct locking and unlocking conditions.

Eurocopter has also issued ASB No. 67.00.12, Revision 0, dated February 25, 2009, for Model AS365 helicopters; ASB No. 67.07, Revision 0, dated February 25, 2009, for Model AS366 helicopters; and ASB No. 67–009, Revision 1, dated July 19, 2010, for Model EC 155 helicopters. These ASBs contain the procedures for MOD 0767B65.
Costs of Compliance

We estimate that this AD will affect 32 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Inspecting and adjusting the collective pitch lever will require about 1 work hour at an average labor rate of $85 per hour, for a total cost per helicopter of $85 and a cost to U.S. operators of $2,720.
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 helicopters identified in this rulemaking
action.
Regulatory Findings

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 this AD:

(1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866;

(2) Is not a ‘‘significant rule’’ under 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 AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
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**

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F.27 Mark 050 airplanes, and Model F.28 Mark 0070 and 0100 airplanes. This AD was prompted by reports of loose nuts on contactors in the electrical power center (EPC), and in some cases, burned contactors. This AD requires inspecting and, if necessary, adjusting, the torque values of nuts on circuit breakers, contactors, and terminal blocks of the EPC and battery relay panel. This AD also requires inspecting to determine if certain parts are installed, and installing the parts if necessary. We are issuing this AD to detect and correct loose nuts, which could result in arcing and potentially an onboard fire, possibly resulting in damage to the airplane and injury to occupants or maintenance personnel.

**DATES :**  This AD becomes effective October 18, 2013.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 18, 2013.
