14 CFR Part 39

[Docket No. FAA-2022-0393; Project Identifier MCAI-2021-01249-T; 
Amendment 39-22131; AD 2022-16-02]

Airworthiness Directives; Airbus Canada Limited Partnership (Type 
Certificate Previously Held by C Series Aircraft Limited Partnership 
(CSALP); Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-
1A11 airplanes. This AD was prompted by the discovery that overwing 
emergency exit door (OWEED) handle covers were difficult to open on 
some airplanes. This AD requires replacing the existing OWEED handle 
cover brackets with newly designed OWEED handle cover brackets and 
installing placards regarding this replacement, as specified in a 
Transport Canada Civil Aviation (TCCA) AD, which is incorporated by 
reference. The FAA is issuing this AD to address the unsafe condition 
on these products.

DATES: This AD is effective November 25, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 25, 
2022.

SUPPLEMENTARY INFORMATION:

Background

    TCCA, which is the aviation authority for Canada, has issued TCCA 
AD CF-2021-39, dated November 10, 2021 (TCCA AD CF-2021-39) (also 
referred to as the MCAI), to correct an unsafe condition for certain 
Airbus Canada Limited Partnership Models BD-500-1A10 and BD-500-1A11 
airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Airbus Canada 
Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. The 
NPRM published in the Federal Register on April 6, 2022 (87 FR 19815). 
The NPRM was prompted by the discovery that OWEED handle covers were 
difficult to open on some airplanes. An investigation revealed that 
brackets of certain OWEED handle covers are prone to flexure, thus 
increasing the force necessary to remove the OWEED handle cover beyond 
design requirements. As a result, the OWEED handle covers must be 
removed in order to access the emergency exit, which could delay 
passenger evacuation. The NPRM proposed to require replacing the 
existing OWEED handle cover brackets with newly designed OWEED handle 
cover brackets and installing a placard regarding this replacement, as 
specified in TCCA AD CF-2021-39.
    The FAA is issuing this AD to address the increased force necessary 
to remove the OWEED handle cover to access the emergency exit, which 
could hinder passenger evacuation in emergency. See the MCAI for 
additional background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from an individual who supported the 
NPRM without change.
    The FAA also received a comment from Delta Airlines (DAL). The 
following presents that comment received on the NPRM and the FAA's 
response.

Request To Clarify Part Numbers for the SB Incorporation Placard

    DAL found that the SB Incorporation Placard is identified as two 
different part numbers, CDPL604-5 and CDPL604-5-F493000-25-01, in 
Safran Service Bulletin F493000-25-01, Revision 1, dated September 17, 
2020, which is referenced in TCCA AD CF-2021-39. The Safran component 
maintenance manual (CMM) states ``true part number is CDPL604-5-
F493000-25-01, added by service bulletin F493000-25-01'' in the 
nomenclature for part number ``CDPL604-5F49300'' described as 
``placard, service bulletin incorporation (bonded).'' The Safran CMM 
has another part number that begins with ``CDPL604-5,'' but with a 
different suffix. The service bulletin does not state the full true 
part number CDPL604-5-F493000-25-01. DAL requested that paragraph (h) 
of the proposed AD be revised to add an Exception that clarifies the 
part numbers.
    The FAA partially agrees with the request. The FAA agrees that two 
part numbers, CDPL604-5 and CDPL604-5-F493000-25-01, were identified 
for the SB Incorporation Placard, and that both

[[Page 63934]]

part numbers are correct and represent the same part. However, the FAA 
disagrees with the need to revise paragraph (h) of this AD to provide 
further clarification of the part numbers. The replacement kit includes 
the correct placard for installation. This AD has not been changed with 
regard to this request.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety requires adopting this AD as 
proposed. Except for minor editorial changes, and any other changes 
described previously, this AD is adopted as proposed in the NPRM. None 
of the changes will increase the economic burden on any operator. 
Accordingly, the FAA is issuing this AD to address the unsafe condition 
on these products.

Related Service Information Under 1 CFR Part 51

    TCCA AD CF-2021-39 specifies procedures for replacing the existing 
OWEED handle cover brackets with newly designed OWEED handle cover 
brackets and installing placards regarding this replacement.
    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 21 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255...........................             $40             $295           $6,195
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 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

    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.

    This AD applies to Airbus Canada Limited Partnership (Type 
Certificate Previously Held by C Series Aircraft Limited Partnership 
(CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11 
airplanes, certificated in any category, as identified in Transport
