SUPPLEMENTARY INFORMATION: 

Background 

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 Model 

AS332C, AS332C1, AS332L, AS332L1, 

and SA330J helicopters. The NPRM 

published in the Federal Register on 

June 18, 2024 (89 FR 51468). The NPRM 

was prompted by a series of ADs, the 

most recent being EASA AD 2023–0076, 

dated April 11, 2023 (EASA AD 2023– 

0076), issued by EASA, which is the 

Technical Agent for the Member States 

of the European Union, to correct an 

unsafe condition on Airbus Helicopters 

Model SA 330 J, AS 332 C, AS 332 C1, 

AS 332 L, and AS 332 L1 helicopters. 

In the NPRM, the FAA proposed to 

require inspecting or measuring the 

MGB forward and rear suspension bar 

attachment plates and, depending on 

the results, taking corrective action. The 

FAA is issuing this AD to address the 

unsafe condition on these products.

0076 in the AD docket at regulations.gov 

under Docket No. FAA–2024–1686. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Conclusion 

These products have been approved 

by the aviation authority of another 

country and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with this 

State of Design Authority, it has notified 

the FAA of the unsafe condition 

described in the EASA AD referenced 

above. 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 

products. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

EASA AD 2023–0076 requires 

measuring the thickness of the MGB 

forward suspension bar attachment 

plate and inspecting the LH and RH 

MGB rear suspension bar attachment 

plates. Depending on the results, EASA 

AD 2023–0076 requires contacting AH 

[Airbus Helicopters] for approved 

corrective action instructions and 

accomplishing those instructions 

accordingly. 

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 Material 

The FAA reviewed Airbus Helicopters 

Alert Service Bulletin (ASB) No. 

AS332–53.02.15, Revision 0, dated 

March 6, 2023, and ASB No. SA330– 

53.56, Revision 0, dated April 3, 2023. 

This material specifies procedures for 

measuring the thickness of the MGB 

front suspension bar attachment plate 

and visually checking the LH and RH 

MGB rear suspension bar attachment 

plate versions. Depending on the 

results, this material specifies 

procedures for contacting Airbus 

Helicopter to get an approved repair. 

Differences Between This AD and the 

EASA AD 

If, during the inspection or 

measurement, any discrepancy is 

detected, EASA AD 2023–0076 specifies 

contacting AH [Airbus Helicopters] to 

obtain approved corrective action 

instructions and accomplishing those 

instructions, and the material referenced 

in EASA AD 2023–0076 specifies 

contacting Airbus Helicopters to get an 

approved repair, whereas this AD 

requires accomplishing the corrective 

action before further flight in 

accordance with a method approved by 

the FAA, EASA, or Airbus Helicopters’ 

EASA Design Organization Approval. 

Costs of Compliance 

The FAA estimates that this AD 

affects 38 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. 

Measuring the thickness of the MGB 

forward suspension bar attachment 

plate and inspecting the LH and RH 

MGB rear suspension bar attachment 

plates will take approximately 2 workhours for an estimated cost of $170 per 

helicopter and $6,460 for the U.S. fleet. 

The corrective action that may be 

needed as a result of the inspection or 

measurement could vary significantly 

from helicopter to helicopter. The FAA 

has no data to determine the costs to 

accomplish the corrective action or the 

number of helicopters that may require 

corrective action. 

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.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all The Boeing Company Model 

787–8, 787–9, and 787–10 airplanes. 

The NPRM published in the Federal 

Register on February 6, 2024 (89 FR 

8109). The NPRM was prompted by a 

determination that the flight deck door 

decompression panel can strike the 

captain’s seat headrest if a flight deck or 

below the flight deck rapid 

decompression event occurs when the 

seat is in a certain position. In the 

NPRM, the FAA proposed to require, for 

certain airplanes, replacing the affected 

captain’s seat assembly. The FAA also 

proposed to prohibit the installation of 

affected parts. The FAA is issuing this 

AD to address the possibility that the 

decompression panel could strike the 

captain’s head or face. The unsafe 

condition, if not addressed, could result 

in serious or potentially fatal injury to
