2020-07354. Airworthiness Directives; Airbus Helicopters

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters. This proposed AD was prompted by a mechanical deformation found on the protective cover of the “SHEAR” control pushbutton installed on a copilot collective stick. This proposed AD would require modification of the helicopter by replacing the protective cover and re-identifying the part number (P/N) of the pilot and copilot collective sticks. The FAA is proposing this AD to address the unsafe condition on these products.

DATES:

The FAA must receive comments on this proposed AD by May 26, 2020.

ADDRESSES:

Discussion

The European Union Aviation Safety Agency (previously European Aviation Safety Agency) (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2018-0106, dated May 10, 2018 (referred to after this as “the MCAI”), to correct an unsafe condition for all Airbus Helicopters Model EC225LP helicopters. EASA advises that mechanical deformation was found on the protective cover of the “SHEAR” control pushbutton on a copilot collective stick. The root cause for the deformation was identified as incorrect handling. This condition, if not corrected, could lead to unintended shearing of the hoist cable, possibly resulting in loss of a hoisted load or person(s). To address this unsafe condition, the EASA AD requires replacement of the protective cover of the “SHEAR” control pushbutton and re-identification (new AH P/N 704A41110149, new NSE MP/N 00014100AA) of the pilot and copilot collective sticks. The EASA AD also prohibits installation of the old design protective cover.

You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-0214.

Related Service Information Under 1 CFR Part 51

Airbus Helicopters has issued Alert Service Bulletin EC225-67A017, Revision 0, dated March 26, 2018. This service information describes procedures for modification of the helicopter by replacing the protective cover of the “SHEAR” control pushbutton and re-identifying the part number of the pilot and copilot collective sticks.

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.

FAA's Determination

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI and service information referenced above. The FAA is proposing this AD after evaluating all the relevant information and determining the unsafe condition described previously is likely to exist or develop on other products of the same type design.

Proposed Requirements of This NPRM

This proposed AD would require accomplishing the actions specified in the service information described previously.

Costs of Compliance

The FAA estimates that this proposed AD affects 12 helicopters of U.S. registry. The FAA estimates the following costs to comply with this proposed AD:

Estimated Costs for Required Actions

Labor cost	Parts cost	Cost per product	Cost on U.S. operators
2 work-hours × $85 per hour = $170	$2,632	$2,802	$33,624

According to the manufacturer, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate.

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

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) 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.

List of Subjects in 14 CFR Part 39

• Air transportation
• Aircraft
• Aviation safety
• Incorporation by reference
• Safety

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

[Amended]

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

Airbus Helicopters: Docket No. FAA-2020-0214; Product Identifier 2018-SW-039-AD.

(a) Comments Due Date

The FAA must receive comments by May 26, 2020.

(b) Affected ADs

None.

(c) Applicability

This AD applies to all Airbus Helicopters Model EC225LP helicopters, certificated in any category.

(d) Subject

Joint Aircraft System/Component Codes (JASC) Code 67, Rotorcraft Flight Controls.

(e) Reason

This AD was prompted by mechanical deformation found on the protective cover of the “SHEAR” control pushbutton installed on a copilot collective stick. The FAA is issuing this AD to address this condition, which could lead to unintended shearing of the hoist cable, possibly resulting in loss of a hoisted load or person(s).

(f) Compliance

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

(g) Definitions

For the purposes of this AD, the definitions specified in paragraphs (g)(1) through (3) of this AD apply.
