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: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-
500-1A11 airplanes. This proposed AD was prompted by reports of flight 
control (horizontal stabilizer, rudder, and elevator) decals degrading 
and peeling (damage), reports of operators painting over these decals, 
and reports that procedures to replace these decals were inaccurate, 
potentially causing incorrect positioning of replacement decals. This 
proposed AD would require inspecting the left and right horizontal 
stabilizer decals for visibility and damage; and for certain airplanes, 
inspecting the rudder and left and right elevator decals for visibility 
and damage; and doing applicable corrective actions, as specified in a 
Transport Canada Civil Aviation (TCCA) AD, which is proposed for 
incorporation by reference. The FAA is proposing this AD to address the 
unsafe condition on these products.

Background

    TCCA, which is the aviation authority for Canada, has issued TCCA 
AD CF-2022-01, dated January 7, 2022 (TCCA AD CF-2022-01) (also 
referred to as the MCAI), to correct an unsafe condition for certain 
Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 
airplanes.
    This proposed AD was prompted by reports of flight control decals 
degrading and peeling, reports of operators painting over these decals, 
and reports that procedures to replace these decals were inaccurate, 
potentially causing incorrect positioning of replacement decals. An 
investigation determined that the degradation and peeling of the flight 
control decals was caused by an incorrect clear protective coating 
being applied during production, and that flight control decals were 
being painted over because of unclear in-service procedures. 
Additionally, the in-service procedures used for replacing these decals 
were not accurate, potentially causing incorrect positioning of the 
replacement decals. The in-service procedures were revised to clearly 
state that the flight control decals are to be masked prior to 
painting, and to ensure the flight control decals are properly placed 
going forward.
    The FAA is proposing this AD to address flight control decals that 
are damaged or incorrectly positioned, which could introduce rigging 
offset of flight control surfaces, and when combined with other 
failures or severe maneuvers, could result in loss of flight control 
surface effectiveness or structural loading that exceeds the airframe's 
capability. See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    TCCA CF-2022-01 specifies procedures for inspecting the left and 
right horizontal stabilizer decals for visibility and damage, and 
corrective actions. For certain airplanes, TCCA CF-2022-01 specifies 
procedures for inspecting the rudder and left and right elevator decals 
for visibility and damage. The corrective actions include replacing, 
restoring, and preserving the condition and placement of the flight 
control decals, and re-rigging the rudder and elevator control 
surfaces. 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.

FAA's Determination

    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 the State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
referenced above. The FAA is issuing this NPRM after determining that 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in TCCA AD CF-2022-01 described previously, except for any differences 
identified as exceptions in the regulatory text of this proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate TCCA AD CF-2022-01 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
TCCA AD CF-2022-01 in its entirety through that incorporation, except 
for any differences identified as exceptions in the regulatory text of 
this proposed AD. Service information required by TCCA AD CF-2022-01 
for compliance will be available at www.regulations.gov by searching 
for and locating Docket No. FAA-2022-0981 after the FAA final rule is 
published.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 56 airplanes 
of U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

[[Page 45711]]



                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
10 work-hours x $85 per hour = $850..........................              $0             $850          $47,600
----------------------------------------------------------------------------------------------------------------


                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
4 work-hours x $85 per hour = $340....            $220             $560
------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition re-rigging actions specified in this 
proposed AD.
    According to the manufacturer, some or all of the costs of this 
proposed 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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
