This AD requires replacing each affected emergency flashlight with a serviceable part, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Background

EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0231, dated October 15, 2021 (EASA AD 2021-0231), to correct an unsafe condition for all serial-numbered Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-2 helicopters.

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 (AHD) Model MBB-BK 117 C-2 helicopters, certificated in any category. The NPRM published in the Federal Register on February 15, 2022 (87 FR 8439). 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 2021-0231.

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, this AD is adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

EASA AD 2021-0231 requires replacing each affected emergency flashlight with a serviceable part. EASA AD 2021-0231 also specifies that an affected part can be modified and re-identified into a serviceable part. EASA AD 2021-0231 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 also reviewed Airbus Helicopters Alert Service Bulletin ASB MBB-BK117 C-2-25A-021, Revision 0, dated August 25, 2021. This service information specifies procedures for removing the strap from the emergency flashlight and then writing a new part number on the emergency flashlight.

Differences Between This AD and the EASA AD

EASA AD 2021-0231 requires compliance within 12 months after the effective date of the EASA AD, whereas this AD requires compliance within 3 months after the effective date of this AD.

Costs of Compliance

The FAA estimates that this AD affects 117 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 and up to $35,568 for the U.S. fleet. 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.

List of Subjects in 14 CFR Part 39

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

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.

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

2022-08-15 Airbus Helicopters Deutschland GmbH (AHD): Amendment 39-22018; Docket No. FAA-2022-0100; Project Identifier MCAI-2021-01128-R.

(a) Effective Date

This airworthiness directive (AD) is effective May 26, 2022.

(b) Affected ADs

None.

(c) Applicability

This AD applies to Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-2 helicopters, certificated in any category.

(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, possibly 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, European Union Aviation Safety Agency (EASA) AD 2021-0231, dated October 15, 2021 (EASA AD 2021-0231).

(h) Exceptions to EASA AD 2021-0231

(1) Where EASA AD 2021-0231 refers to its effective date, this AD requires using the effective date of this AD.

(2) This AD does not mandate compliance with the “Remarks” section of EASA AD 2021-0231.

(3) Where paragraph (1) of EASA AD 2021-0231 requires replacing each affected part with a serviceable part within 12 months, this AD requires compliance within 3 months after the effective date of this AD.

(i) No Reporting Requirement

Although the service information referenced in EASA AD 2021-0231 specifies to submit certain information to the manufacturer, this AD does not include that requirement.

(j) Alternative Methods of Compliance (AMOCs)

(1) The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the International Validation Branch, send it to the attention of the person identified in paragraph (k) of this AD. Information may be emailed to: 9-AVS-AIR-730-AMOC@faa.gov.

(2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office.
