**Airworthiness Directives; Airbus Helicopters** 

**AGENCY :**  Federal Aviation Administration (FAA), Department of Transportation (DOT).

**ACTION :**  Final rule; request for

comments.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters with certain external life rafts. This AD requires installing a sheath kit on the left-hand and right-hand raft deployment control systems. This AD is prompted by a report that the life raft deployment control could not be adjusted due to problems with the life raft deployment linkage. This unsafe condition, if not corrected, could result in failure of the external life raft to deploy and prevent evacuation of passengers during an

emergency.

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


### 12805 Federal Register / Vol. 81, No. 48 / Friday, March 11, 2016 / Rules and Regulations

provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs.

Related Service Information Under 1 CFR Part 51

We reviewed Airbus Helicopters Alert Service Bulletin (ASB) No. AS365– 25.01.45 and ASB No. EC155–25A128, both Revision 1, and both dated February 2, 2015. The service information reports that the position of the life raft inflation cylinder may slacken the deployment control cable for new life rafts installed on Model AS 365 N3, EC 155B, and EC155B1 helicopters. In one instance, travel of the life raft deployment control could not be adjusted as stated in the maintenance manual. This anomaly is due to the varying positions of the inflation cylinder inside the bag that contains the life raft, and the varying positions of the bag inside the container, related to the installation and removal of optional equipment, calendar overhauls, life raft storage, shock impacts, and in-flight vibrations. Airbus Helicopters consequently developed modification 365A084711.00 and 365A084711.01, which ensure sufficient travel of the life raft deployment control cable in all positions of the inflation cylinder by installing an improved sheath kit on the left hand and right hand deployment controls.

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.
AD Requirements

This AD requires, before the next flight over water, installing a sheath kit on the left-hand and right-hand raft deployment controls.

Differences Between This AD and the EASA AD

The EASA AD requires installing asheath kit on the left-hand and righthand raft deployment controls within 110 hours time-in-service or before further flight for helicopters required to have life rafts, whichever occurs later. This AD requires installing a sheath kit on the left-hand and right-hand raft deployment controls before the next flight over water.
Costs of Compliance

We estimate that this proposed AD affects 23 helicopters of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we expect that installing the sheath kits requires 4 work-hours and a parts cost of $50 for a total cost of $390 per helicopter and $8,970 for the U.S. fleet.
FAA’s Justification and Determination of the Effective Date

Providing an opportunity for public comments prior to adopting these AD requirements would delay implementing the safety actions needed to correct this known unsafe condition. Therefore, we find that the risk to the flying public justifies waiving notice and comment prior to the adoption of this rule because many of the affected helicopters are located along major waterways, and the required corrective actions must be accomplished before the next flight over water.

Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for prior public comment before issuing this AD are impracticable and contrary to the public interest and that good cause exists to make this AD effective in less than 30 days.
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, 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

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2013–08–23, Amendment 39–17441 (78 FR 24037, April 24, 2013). AD 2013–08–23 applied to all The Boeing Company Model DC– 10–10, DC–10–10F, DC–10–15, DC–10– 30, DC–10–30F (KC–10A and KDC–10), DC–10–40, DC–10–40F, MD–10–10F, MD–10–30F, MD–11, and MD–11F airplanes. The NPRM published in the Federal Register on March 27, 2015 (80 FR 16321). The NPRM was prompted by a determination that it is necessary to clarify the requirements for the design features and to remove a terminating action for certain inspections. The NPRM proposed to clarify certain requirements and remove a terminating action. The NPRM also proposed to provide an optional method of compliance for the proposed actions. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (80 FR 16321, March 27, 2015) and the FAA’s response to each comment.
