defined in the ASB,’’ this AD requires 

replacing that text with ‘‘there is any 

gouging.’’ 

Note 1 to paragraph (h)(3): The material 

referenced in EASA AD 2024–0228 provides 

an illustration of gouging. 

(4) This AD does not adopt the ‘‘Remarks’’ 

section of EASA AD 2024–0228. 

(i) No Reporting Requirement 

Although the material referenced in EASA 

AD 2024–0228 specifies to submit certain

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 May 20, 2024 (89 FR 43794). 

The NPRM was prompted by a report of 

operators receiving No. 1 flight 

compartment windows that may not 

meet type design requirements for 

withstanding a bird impact. In the 

NPRM, the FAA proposed to require 

replacing affected No. 1 flight 

compartment windows and prohibit the 

installation of affected windows. The 

FAA is issuing this AD to prevent a 

window from spalling in the event of a 

high-energy bird impact. The unsafe 

condition, if not addressed, could result 

in injuries to crew that may affect 

continued safe flight and landing. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

three commenters, Air Line Pilots 

Association, International (ALPA), 

Boeing Commercial Airplanes, and 

United Airlines, who supported the 

NPRM without change. 

Conclusion 

The FAA reviewed the relevant data, 

considered any comments received, 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. Except for minor editorial 

changes, this AD is adopted as proposed 

in the NPRM. None of the changes will 

increase the economic burden on any 

operator. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin B787–81205– 

SB560010–00 RB, Issue 001, dated 

December 13, 2023. This material 

specifies procedures for determining 

whether a left or right No. 1 flight 

compartment window with certain part 

numbers and serial numbers is installed 

and for replacing any window that has 

an affected part number and serial 

number. 

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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 152 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

airplane 

Cost on U.S. 

operators 

Inspect right and left No. 1 windows .............. 0.25 work-hour × $85 per hour = $21.25 ....... $0 $21.25 $3,230 

The FAA estimates the following 

costs to do any replacement that would 

be required based on the results of the 

inspection. The agency has no way of 

determining the number of airplanes 

that might need these replacements or 

how many replacements each airplane 

may require: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per airplane 

Replace No. 1 window ..................... 16 work-hours × $85 per hour = $1,360 ..................... $104,060 $105,420 per window. 

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.
