(a) EFFECTIVE DATE

    This airworthiness directive (AD) is effective July 22, 2022.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11
    airplanes,  certificated in any category,  serial numbers 9001 through
    9879 inclusive, 9998, and 60001 through 60033 inclusive.

(d) SUBJECT

    Air Transport Association (ATA) of America Code 05,  Time Limits/Main-
    tenance Checks.

(e) REASON

    This AD was prompted by  reports of internal corrosion  on the inboard
    flaps found prior to  regularly scheduled maintenance checks.  The FAA
    is issuing this AD to address internal corrosion on the inboard flaps,
    which could result in reduced structural integrity, detachment of  the
    flap, and consequent reduced controllability of the airplane.

(f) COMPLIANCE

    Comply with this AD within the compliance times specified,  unless al-
    ready done.

(g) REVISION OF THE EXISTING MAINTENANCE OR INSPECTION PROGRAM

    Within  30  days after  the  effective date  of  this AD,  revise  the
    existing maintenance or inspection program, as applicable, to  include
    the information specified in Task 57-51-00-290-801, "Special  Detailed
    Inspection of  the Inboard-Flap  Internal Ribs,"  of Subject 57-51-00,
    "Flaps," in Chapter 57, "Wings," of the applicable Bombardier Aircraft
    Maintenance Manual (AMM)  identified in figure  1 to paragraph  (g) of
    this AD and to include  the following compliance times for  Task 57-51
    -00-290-801: Within 60 months after the effective date of this AD (for
    the initial compliance time),  and repeat thereafter at  intervals not
    to exceed 60 months.

SUPPLEMENTARY INFORMATION:

Background

Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2020-49R1, dated May 20,
2021 (TCCA AD CF-2020-49R1) (also referred to after this as the
Mandatory Continuing Airworthiness Information, or the MCAI), to
correct an unsafe condition for certain Bombardier, Inc., Model BD-700-
1A10 and BD-700-1A11 airplanes. You may examine the MCAI in the AD
docket at https://www.regulations.gov by searching for and locating
Docket No. FAA-2021-0832.
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-700-1A10 and BD-700-1A11 airplanes. The NPRM published
in the Federal Register on September 27, 2021 (86 FR 53246). The NPRM
was prompted by reports of internal corrosion on the inboard flaps
found prior to regularly scheduled maintenance checks. The NPRM
proposed to require revising the existing maintenance or inspection
program, as applicable, to incorporate a certain AMM task. The FAA is
issuing this AD to address internal corrosion on the inboard flaps,
which could result in reduced structural integrity, detachment of the
flap, and consequent reduced controllability of the airplane. See the
MCAI for additional background information.

Comments

The FAA received comments from an individual who supported the NPRM
without change.
The FAA received comments from Bombardier, Inc., and NetJets QC.
The following presents the comments received on the NPRM and the FAA's
response to each comment.

Request To Change Address for Obtaining Service Information

Bombardier asked that the address for obtaining its service
information be updated. Bombardier stated that its contact information
has changed since issuance of the NPRM.
The FAA agrees with the commenter and have changed the address for
obtaining service information throughout this final rule accordingly.

Request To Clarify Why AMM Task Number Was Used

NetJets QC asked if there is a reason why the AMM task number was
used instead of the time limits maintenance checks (TLMC) task number.
The FAA acknowledges the commenter's request for clarification.
TCCA AD CF-2020-49R1 references TLMC tasks for Models BD-700-1A10 and
BD-700-1A11, but Part 3 of the TLMC document specifies that all tasks
in that section are Maintenance Review Board Report (MRBR) tasks. The
FAA cannot require MRBR tasks because those tasks do not provide
precise instructions on how the tasks must be done. Therefore, the AMM
task for each airplane model is referenced in this AD, and the FAA has
not changed this AD in this regard.

Request To Refer to Most Recent AMM Revision Level

Bombardier asked that the AMM task revision levels identified in
the NPRM be changed, as there have been recent improvements to the
documents. Bombardier added that credit for the revisions currently
listed should also be included in the proposed AD. Bombardier noted
that the referenced AMM revision levels were revised
during the public comment period of the NPRM.
The FAA disagrees with the commenter's request. This AD requires
incorporating the information provided in the referenced AMM revisions
specified in figure 1 to paragraph (g) of this AD. The language in
paragraph (g) of this AD allows the incorporation of the specific
information, regardless of the AMM revision level in use, provided the
language is identical to the information provided in Task 57-51-00-290-
801 specified in the applicable AMMs in specified in figure 1 to
paragraph (g) of this AD. The language in a later revision of the
applicable AMMs specified in figure 1 to paragraph (g) of this AD may
be incorporated. Therefore, if operators incorporate later AMMs into
the maintenance or inspection program, as applicable, they are in
compliance with paragraph (g) of this AD. The FAA has confirmed that
the revisions cited by the commenter are identical to the revisions
specified in this AD.
If the language provided in a later AMM revision is not identical
to the language provided in the task specified in the applicable AMMs
specified in figure 1 to paragraph (g) of this AD, operators must
submit a request for approval of an alternate method of compliance
(AMOC) with supporting data that demonstrates an acceptable level of
safety for a task that differs from Task 57-51-00-290-801.
The FAA has not changed this AD regarding this request.

Request To Change ``Unsafe Condition'' to ``Potential Unsafe
Condition''


Bombardier asked that the FAA change references to the ``unsafe
condition'' in the preamble of the NPRM to ``potential unsafe
condition.'' Bombardier provided no justification for this request.
The FAA disagrees with the commenter's request. The definition of
the unsafe condition in this final rule was determined by findings of
internal corrosion on the inboard flaps. In addition, the unsafe
condition was addressed in the background section of TCCA AD CF-2020-
49R1. Stating that there is potential for an unsafe condition is
misleading as it would imply that corrosion wasn't found previously.
Therefore, the FAA has not changed this final rule regarding this
request.

Request To Change Description of the Unsafe Condition in Paragraph (e)
of the Proposed AD


Bombardier asked that the language describing the unsafe condition
specified in paragraph (e) of the proposed AD be changed to add more
detail, as follows: ``The FAA is issuing this AD to supplement
operator's maintenance program by mandating a periodic inspection of
the internal structures of the flaps to prevent a possible reduction in
the structural integrity, detachment of the flap, and consequent
reduced controllability of the airplane.'' Bombardier provided no
justification for this request.
The FAA disagrees with the commenter's request. The purpose of the
description of the unsafe condition in paragraph (e) of this AD is to
indicate why a problem is unsafe and the possible results and ultimate
consequences if the unsafe condition is not corrected. The FAA is
issuing this AD to address the unsafe condition by requiring revision
of the existing maintenance or inspection program by mandating
inspections of the internal structures of the flaps to address the
internal corrosion. The FAA is not issuing this AD to ``supplement the
operator's maintenance program by mandating a periodic inspection of
the internal structures to prevent a possible reduction in the
structural integrity.'' The FAA has not changed this AD in this regard.

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.

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 141 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
The FAA has determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although the
agency recognizes that this number may vary from operator to operator.
Since operators incorporate maintenance or inspection program changes
for their affected fleet(s), the FAA has determined that a per-operator
estimate is more accurate than a per-airplane estimate. Therefore, the
agency estimates the average total cost per operator to be $7,650 (90
work-hours x $85 per work-hour).

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:
