AD 2014-02-09

We are adopting a new airworthiness directive (AD) for Eurocopter Model EC225LP and AS332L1 helicopters with emergency floatation gear. The AD requires, before the next overwater flight, inspecting the strap installation on the hinged rods of the emergency flotation gear on both rear cradles for correct installation. If a strap is installed under the hinged rod median plate rather than over it, reinstalling the strap is required. The AD is prompted by incorrect routing of the straps on the hinged rods of the emergency flotation gear rear cradles. The actions are intended to detect incorrect strap installation and prevent failure of the rods or straps upon deployment of the emergency flotation gear, incorrect float position, and subsequent capsizing of the helicopter.

Final rule; request for comments.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

Discussion

We are adopting a new AD for Eurocopter Model EC225LP and

[[Page 7387]]

AS332L1 helicopters. The AD requires, before the next overwater flight, inspecting the strap installation on the hinged rods of the emergency flotation gear for both rear cradles for correct installation. If at least one strap is incorrectly installed, the AD requires reinstalling the strap over the hinged rod median plate rather than under it. The AD is prompted by incorrect routing of the straps on Model EC225LP. Investigation indicates that the maintenance work cards and tasks for Model EC225LP and AS332L1 helicopters are not specific enough to describe the removal or installation of the emergency flotation gear rear cradle assembly, which can lead to incorrect routing of the straps. The maintenance work cards and tasks for other Eurocopter helicopters aremore precise about the removal or installation for the rear cradle.
EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2013-0237-E, dated September 26, 2013, to correct an unsafe condition for Eurocopter Model EC225LP helicopters equipped with emergency flotation gear and Model AS332L1 helicopters equipped with emergency flotation gear with Eurocopter Modification (MOD) OP26277. EASA advises of incorrect routing of the straps on the hinged rods of left-hand (LH) side and right-hand (RH) side rear cradles of the emergency flotation gear installation on several recently delivered Model EC225 helicopters. According to EASA, the straps were routed over the median plate of the hinged rod instead of under it. EASA further advises that some Model AS332L1 helicopters (those incorporating MOD OP26277) are equipped with an emergency flotation gear of similar design. EASA states that this condition, if not detected and corrected, could leadto failure of the hinged rods and straps upon deployment of the emergency flotation gear during ditching and consequent unsafe positioning of the rear floats, possibly resulting in a helicopter capsizing. Therefore, the EASA AD requires a one-time inspection of the hinged rods of the emergency flotation gear LH and RH rear cradles and accomplishing applicable corrective actions.

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.

Related Service Information

Eurocopter issued one Emergency Alert Service Bulletin (EASB), Revision 0, dated September 25, 2013, with four different numbers: No. 25.02.76 relates to the FAA type-certificated Model AS332L1 helicopter and to the military Model AS332M1 helicopter. No. 25.01.62 relates to military Model AS532AL and UL helicopters. No. 25A142 relates to the FAA type-certificated Model EC225LP helicopter. No. 25A060 relates to the military Model EC725AP helicopter. The EASB specifies checking the routing of the straps on the hinged rods of the emergency flotation gear LH and RH rear cradles and making the installation compliant if necessary.

AD Requirements

The AD requires before the next overwater flight:
Inspecting the strap installation on the hinged rods of the emergency flotation gear on both rear cradles for correct installation.
If any strap is routed under the hinged rod's median plate, reinstalling the strap so that the strap is routed over the median plate.

Costs of Compliance

We estimate that this AD will affect 14 helicopters ofU.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. We estimate 0.25 work-hour to inspect each helicopter for correct installation of the strap for a total of $21 per helicopter and $294 for the fleet. We estimate 0.5 work-hour to correct any improper installation of the straps for a total of $43 per helicopter.

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. The required corrective actions must be done prior to the next overwater flight, which are prohibited until the inspection of the strap for incorrect routing on the hinged rods of the rear cradles of the emergency flotation gear installation is done. Therefore, we find that the risk to the flying public justifies waiving notice and comment period prior to adopting this rule because some of these helicopters are used exclusively for offshore operations.
Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment 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.
