Conclusion
The FAA reviewed the relevant data, considered the comments received, and determined that air
safety and the public interest require adopting this final rule with the changes described previously
and minor editorial changes. The FAA has determined that these minor changes:
• Are consistent with the intent that was proposed in the NPRM for addressing the unsafe
condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM.
The FAA also determined that these changes will not increase the economic burden on any
operator or increase the scope of this final rule.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Alert Service Bulletin 737-24A1148, Revision 2, dated September
14, 2020. This service information describes procedures for repetitive records checks to determine
exposure to certain deicing fluids or repetitive inspections for corrosion of the electrical connectors,
and corrective actions if necessary. 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.
Costs of Compliance
The FAA estimates that this AD affects 346 airplanes of U.S. registry. The FAA estimates the
following costs to comply with this AD:
Estimated Costs
Action Labor cost Parts Cost per Cost on U.S.
cost product operators
Repetitive records 1 work-hour × $85 per hour = $0 $85 per Up to $29,410 per
check $85 per inspection cycle inspection cycle inspection cycle
Repetitive detailed 3 work-hours × $85 per hour = $0 $255 per Up to $88,230 per
inspection $255 per inspection cycle inspection cycle inspection cycle
The FAA estimates the following costs to do any necessary repairs or replacements that would
be required based on the results of the inspection. The FAA has no way of determining the number of
aircraft that might need these repairs or replacements:
On-Condition Costs
Action Labor cost Parts cost Cost per
product
Cleaning or Up to 5 work-hours × $85 per hour = Up to Up to Up to $1,256
replacement $425 $831
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety.
27.05.2021
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.
5
LUFTTÜCHTIGKEITSANWEISUNGEN
2021-2-615
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.

EASA AD No.: 2021-0127
Reason:
During type certification activity, it was identified that some monitoring was not correctly
implemented in the BCS certification standard, that could, under specific degraded conditions, lead
to a reduction in braking performance capability.
This condition, if not corrected, could lead to a runway excursion, possibly resulting in damage to
the aeroplane and injury to occupants.
To address this potential unsafe condition, Airbus developed new SW standards for BCS, WSCS and
LGERS and issued the SB, providing instructions to install serviceable SW, as defined in this AD.
For the reason described above, this AD requires installation of serviceable SW.
Required Action(s) and Compliance Time(s):
Required as indicated, unless accomplished previously:
Modification:
Within 10 months after the effective date of this AD, modify the aeroplane by installing serviceable
SW. This can be accomplished in accordance with the instructions of the SB.
Ref. Publications:
Airbus SB A350-32-P037 original issue dated 30 July 2019.
The use of later approved revisions of the above-mentioned document is acceptable for compliance
with the requirements of this AD.
Remarks:
1. If requested and appropriately substantiated, EASA can approve Alternative Methods of
Compliance for this AD.
2. This AD was posted on 12 April 2021 as PAD 21-054 for consultation until 10 May 2021. The
Comment Response Document can be found in the EASA Safety Publications Tool, in the
compressed (zipped) file attached to the record for this AD.
3. Enquiries regarding this AD should be referred to the EASA Safety Information Section,
