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 a report indicating that during 
production, the manual opening and closing of the over-wing emergency 
exit door (OWEED) prior to the installation of the OWEED interior panel 
could have resulted in damaged insulation blankets below the left and 
right OWEEDs. This AD requires a one-time inspection for damage of the 
insulation blankets below the left and right OWEEDs, and replacement if 
necessary, 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 March 3, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 3, 
2022.

SUPPLEMENTARY INFORMATION:

Background

    TCCA, which is the aviation authority for Canada, issued TCCA AD 
CF-2021-03 on February 11, 2021 (TCCA AD CF-2021-03) (also referred to 
as the Mandatory Continuing Airworthiness Information, or the MCAI), to 
correct an unsafe condition for certain Airbus Canada Limited 
Partnership Model 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

[[Page 4149]]

BD-500-1A11 airplanes. The NPRM published in the Federal Register on 
August 3, 2021 (86 FR 41788). The NPRM was prompted by a report 
indicating that during production, the manual opening and closing of 
the OWEED prior to the installation of the OWEED interior panel could 
have resulted in damaged insulation blankets below the left and right 
OWEEDs. The NPRM proposed to require a one-time inspection for damage 
of the insulation blankets below the left and right OWEEDs, and 
replacement if necessary, as specified in TCCA AD CF-2021-03.
    The FAA is issuing this AD to address potential damage to the 
insulation blankets, which could result in delayed passenger evacuation 
in the event of post-crash/post-impact fire events outside the 
airplane. See the MCAI for additional background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from one commenter, Delta Air Lines 
(DAL). The following presents the comment received on the NPRM and the 
FAA's response to that comment.

Request To Omit Exception

    DAL asked that the FAA remove the exception identified in paragraph 
(h)(2) of the proposed AD, since it provides no value to the end 
product. DAL stated that the instructions in TCCA AD 
CF[dash]2021[dash]03, and Airbus Canada Service Bulletin 
BD500[dash]258003, Issue 001, dated November 5, 2020, include 
implementation of corrective action for discrepancies, and neither 
allows deferring any corrective actions beyond maintenance after the 
inspection is done and corrosion is documented.
    The FAA does not agree with the commenter's request. This exception 
was included to require replacement of any damaged insulation blanket 
before further flight, because no separate compliance time was provided 
in the referenced service information for the corrective actions. 
Without the exception specified in paragraph (h)(2) of this AD, 
operators could wait until the end of the compliance time (4,500 flight 
hours or 24 months after the effective date of this AD, whichever 
occurs first) to replace damaged insulation blankets, instead of 
replacing them before further flight. Therefore, the FAA has not 
changed this AD in this regard.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety requires adopting this AD as 
proposed. 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. 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-2021-03 describes procedures for a one-time visual 
inspection for damage of the insulation blankets below the left and 
right OWEEDs, and replacement of any damaged insulation blankets. 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 33 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...........................              $0             $255           $8,415
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition action that will be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need this on-condition action:

                 Estimated Costs of On-Condition Action
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
2 work-hours x $85 per hour = $170....            $150             $320
------------------------------------------------------------------------

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.
