## Background

EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0281, dated December 16, 2020 (EASA AD 2020-0281), to correct an unsafe condition for certain serial-numbered Airbus Helicopters (AH), formerly Eurocopter, Eurocopter France, Aerospatiale Model AS 332 L2 and EC 225 LP helicopters.

This proposed AD was prompted by a design deficiency involving the incorrect wiring routing of the electrical hoist installation. The affected wiring was not protected by the circuit breaker that was intended to provide electrical protection for that wiring. The FAA is proposing this AD to correct the electrical hoist installation wiring routing. See EASA AD 2020-0281 for additional background information.

## Related Service Information Under 1 CFR Part 51

EASA AD 2020-0281 requires modifying the hoist control power supply.

                    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.                

## FAA's Determination

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 is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of these same type designs.

## Proposed AD Requirements in This NPRM

This proposed AD would require accomplishing the actions specified in EASA AD 2020-0281, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD.

## Explanation of Required Compliance Information

                    In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate EASA AD 2020-0281 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2020-0281 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2020-0281 does not mean that operators need comply only with that section. For example, where the AD requirement refers to “all required actions and compliance times,” compliance with this AD requirement is not limited to the section titled “Required Action(s) and Compliance Time(s)” in EASA AD 2020-0281. Service information required by EASA AD 2020-0281 for compliance will be available at                     *https://www.regulations.gov*                     by searching for and locating Docket No. FAA-2021-0693 after the FAA final rule is published.                

## Costs of Compliance

The FAA estimates that this AD, if adopted as proposed, would affect 5 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 proposed AD.

Modifying the electrical hoist control power supply would take about 4 work-hours and parts would cost about $10, for an estimated cost of $350 per helicopter and $1,750 for the affected U.S. fleet.

## 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.                          ( print page 47422)    

## Regulatory Findings

The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:

(1) Is not a “significant regulatory action” under Executive Order 12866,

(2) Would not affect intrastate aviation in Alaska, and

(3) Would 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 Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 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

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

**Airbus Helicopters:**                         Docket No. FAA-2021-0693; Project Identifier MCAI-2020-01666-R.                    

## (a) Comments Due Date

The FAA must receive comments on this airworthiness directive (AD) by October 12, 2021.

## (b) Affected ADs

None.

## (c) Applicability

This AD applies to Airbus Helicopters Model AS332L2 and EC225LP helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2020-0281, dated December 16, 2020 (EASA AD 2020-0281).

## (d) Subject

Joint Aircraft Service Component (JASC) Code: 2500, Cabin Equipment/Furnishings.

## (e) Unsafe Condition

This AD was prompted by a design deficiency. The FAA is issuing this AD to correct the electrical hoist installation wiring routing.
