2022-02752. Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) Helicopters

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters.

SUPPLEMENTARY INFORMATION:

Background

EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0149, dated June 21, 2021 (EASA AD 2021-0149), to correct an unsafe condition for Airbus Helicopters Deutschland GmbH (AHD) Model EC135 P1, EC135 P2, EC135 P2+, EC135 P3, EC135 T1, EC135 T2, EC135 T2+, EC135 T3, EC635 P2+, EC635 P3, EC635 T1, EC635 T2+, and EC635 T3 helicopters, all variants, all serial numbers up to 820 inclusive. Model EC635 P2+, EC635 P3, EC635 T1, EC635 T2+, and EC635 T3 helicopters are not certificated by the FAA and are not included on the U.S. type certificate data sheet (TCDS), except where the TCDS explains that the Model EC635T2+ helicopter having serial number 0858 was converted from Model EC635T2+ to Model EC135T2+. This AD, therefore, does not include Model EC635 P2+, EC635 P3, EC635 T1, EC635 T2+, and EC635 T3 helicopters in the applicability.

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters, certificated in any category, as identified in EASA 2021-0149. The NPRM published in the Federal Register on November 23, 2021 (86 FR 66474). The NPRM was prompted by a report of restricted collective lever movement caused by entanglement of the emergency flashlight strap with the cargo hook emergency release lever, causing the emergency flashlight to leave its seat. The NPRM proposed to require replacing each affected emergency flashlight with a serviceable part, as specified in EASA AD 2021-0149.

The FAA is issuing this AD to address entanglement of the emergency flashlight strap with the cargo hook emergency release lever. See EASA AD 2021-0149 for additional background information.

Discussion of Final Airworthiness Directive

Comments

The FAA received no comments on the NPRM or on the determination of the costs.

Conclusion

These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA's bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these helicopters. Except for minor editorial changes, including updating the name “Airbus Helicopters Deutschland GmbH” to “Airbus Helicopters Deutschland GmbH (AHD)” to match its FAA TCDS type certificate holder name, adding the Other Related Service Information section to describe Airbus Helicopters service information, correcting the issuance date of EASA AD 2021-0149 in the Applicability paragraph, and reformatting and updating the Costs of Compliance section, this AD is adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

EASA AD 2021-0149 requires replacing each affected emergency flashlight with a serviceable part. EASA AD 2021-0149 also specifies that an affected part can be modified and re-identified into a serviceable part. EASA AD 2021-0149 also prohibits the installation of an affected part.

This material 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.

Other Related Service Information

The FAA reviewed Airbus Helicopters Alert Service Bulletin ASB EC135-25A-032, Revision 0, dated May 20, 2021. This service information specifies procedures to remove the strap from the emergency flashlight and what part number to write on the flashlight.

Costs of Compliance

The FAA estimates that this AD affects 335 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD.

Replacing an emergency flashlight takes about 1 work-hour and parts cost about $219 for an estimated cost of $304 per flashlight. Alternatively, modifying an emergency flashlight takes about 1 work-hour for an estimated cost of $85 per flashlight.

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.

The FAA is 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) Will not affect intrastate aviation in Alaska, 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.

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

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

§ 39.13

[Amended]

2. The FAA amends § 39.13 by adding the following new airworthiness directive:

2022-02-19 Airbus Helicopters Deutschland GmbH (AHD): Amendment 39-21916; Docket No. FAA-2021-1012; Project Identifier MCAI-2021-00697-R.

(a) Effective Date

This airworthiness directive (AD) is effective March 17, 2022.

(b) Affected ADs

None.

(c) Applicability

This AD applies to Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2021-0149, dated June 21, 2021 (EASA 2021-0149).

(d) Subject

Joint Aircraft Service Component (JASC) Code: 2510, Flight Compartment Equipment.

(e) Unsafe Condition

This AD was prompted by a report of restricted collective lever movement. Subsequent inspection determined that the emergency flashlight was stuck under that lever caused by entanglement of the emergency flashlight strap with the cargo hook emergency release lever, causing the emergency flashlight to leave its seat. The FAA is issuing this AD to address entanglement of the emergency flashlight strap with the cargo hook emergency release lever. The unsafe condition, if not addressed, could result in reduced control of the helicopter, resulting in damage to the helicopter and injury to occupants.

(f) Compliance

Comply with this AD within the compliance times specified, unless already done.

(g) Requirements

Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2021-0149.
