**SUPPLEMENTARY INFORMATION :** 

Discussion

On September 2, 2015, at 80 FR 53030, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to certain MDHI Model 369A (Army OH–6A), 369H, 369HE, 369HM, 369HS, 369D, 369E, 369F, 369FF, and 500N helicopters. The NPRM proposed to require inspecting the routing of the fuel pump wiring to determine whether the fuel pump wire is properly wrapped around the fuel inlet hose and correcting the routing of the wiring if it is not. The NPRM also proposed to require installing a decal regarding correct installation of the fuel pump wiring. The NPRM was prompted by two accidents and one incident that occurred on Model 369D helicopters resulting from an incorrectly positioned fuel pump wire within the fuel tank interfering with the operation of the fuel quantity sensor float, which caused an erroneous fuel quantity reading in the cockpit. Because the fuel pump is installed on all the affected model helicopters, we are including them in the applicability. According to MDHI, because maintenance personnel caused the incorrect wire routing by failing to follow procedures for installing the fuel pump, it is also necessary to install a decal on the left-hand fuel cell access cover to refer maintenance personnel to the appropriate manual procedures. The proposed requirements were intended to detect and correct routing of the fuel pump wiring to prevent interference with the fuel quantity sensor float, an erroneous fuel quantity indication in the cockpit, and subsequent fuel exhaustion and emergency landing.

Comments

We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM (80 FR 53030, September 2, 2015).

FAA’s Determination

We have reviewed the relevant information and determined that an unsafe condition exists and is likely to exist or develop on other products of the same type designs and that air safety and the public interest require adopting the AD requirements as proposed.

Related Service Information Under 1 CFR Part 51

MD Helicopters issued one service bulletin on April 30, 2014, with five different numbers: SB369H–255, SB369E–111, SB500N–049, SB369D– 213, and SB369F–098. The service bulletin specifies a one-time inspection of the routing of the fuel pump wire in the left-hand fuel cell and corrective action, if necessary. The service bulletin also specifies installing a warning decal on the left-hand fuel cell access cover that refers personnel to the procedures for routing the fuel pump wire that is contained in the appropriate maintenance manual. The service bulletin states that recent field incidents have occurred where maintenance personnel have not followed the procedures for installation of the fuel pump. Also, the service bulletin states that an incorrectly installed fuel pump wire can interfere with the fuel quantity sensor float, which can result in erroneous fuel quantity indications. To prevent this situation, the service information states that the fuel pump wire must be wrapped around the fuel inlet hose as shown in the applicable maintenance manual.

This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the **ADDRESSES** section.


### 12803 Federal Register / Vol. 81, No. 48 / Friday, March 11, 2016 / Rules and Regulations

Costs of Compliance

We estimate that this AD will affect 833 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Inspecting the fuel pump wire routing and installing a decal will take 3 work-hours, and parts will cost $20 for a total cost of $275 per helicopter and $229,075 for the U.S. fleet. If required, rerouting the wiring will require 1 work-hour for a total cost of $85 per helicopter. 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

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

Discussion

EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2015– 0048, dated March 17, 2015, to correct an unsafe condition for Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters. EASA advises that after installation of a new life raft on a helicopter, the travel of the life raft deployment control could not be properly adjusted, putting at risk proper life raft inflation. According to a technical analysis, the varying positions of the life raft inflation cylinder inside the bag containing the life raft, as well as the varying positions of the bag within the life raft container, may cause the life raft deployment control cable to loosen and travel insufficiently.

This condition could result in failure of the external life raft to deploy after a ditching, impeding or preventing the safe evacuation of helicopter occupants, EASA states. EASA consequently requires alteration of the life raft deployment control by installing a sheath kit, which Airbus Helicopters identifies as Modification 365A084711.00 and 365A084711.01.

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
