Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was 
prompted by report that the passenger door functional test engineering 
requirements (FTERs) were not fully accomplished on several airplanes. 
This AD requires measuring the passenger door steps, passenger door 
gaps, and passenger door stops rigging, and re-adjusting the door if 
necessary. The FAA is issuing this AD to address the unsafe condition 
on these products.

DATES: This AD is effective April 7, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 7, 
2023.

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 certain Bombardier, 
Inc., Model BD-700-2A12 airplanes. The NPRM published in the Federal 
Register on December 16, 2022 (87 FR 77040). The NPRM was prompted by 
AD CF-2022-48, dated August 18, 2022, issued by Transport Canada, which 
is the aviation authority for Canada (Transport Canada AD CF-2022-48) 
(also referred to as the MCAI). The MCAI states that non-conformities 
have been reported involving the passenger door FTERs. It has been 
found that the FTER was not fully accomplished on several airplanes 
with the assembled airplane in the weight-on-wheel condition, which 
could affect the rigging of the passenger door. Door mis-rigging could 
result in higher loads on the passenger door stops that could initiate 
cracks before the intended design service goal, and an in-flight 
opening of the passenger door
    In the NPRM, the FAA proposed to require measuring the passenger 
door steps, passenger door gaps, and passenger door stops rigging, and 
re-adjusting the door if necessary. The FAA is issuing this AD to 
address the unsafe condition on these products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1646.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    This product has been approved by the aviation authority of another 
country and is 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 MCAI 
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 this product. 
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.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Bombardier Service Bulletin 700-52-7511, dated 
July 22, 2022. This service information specifies procedures for 
measuring the passenger door steps and gaps, rigging of the passenger 
door stops, and corrective actions if the measurements are not within 
the specified limits. 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 29 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                   Cost per
                  Labor cost                      Parts cost        product          Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 4 work-hours x $85 per hour = $340......              $0            $340  Up to $9,860.
----------------------------------------------------------------------------------------------------------------

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

[[Page 13310]]



                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
            Labor cost                Parts cost      Cost per product
------------------------------------------------------------------------
Up to 30 work-hours x $85 per hour              $0  Up to $3,400.
 = $3,400.
------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this AD may be covered under warranty, thereby reducing the cost impact 
on affected operators.

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.
