Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This proposed AD was prompted by reports of insufficient clearance between the surrounding structure/skin of the aircraft and select bleed air ducts that supply the wing ice protection system (WIPS) in the rear fuselage. This proposed AD would require inspecting the bleed air duct and surrounding structure for minimum clearance and damage, and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2022-05, dated February 24,
2022 (TCCA AD CF-2022-05) (also referred to after this as the MCAI), to
correct an unsafe condition for certain Bombardier, Inc., Model BD-700-
2A12 airplanes. You may examine the MCAI in the AD docket at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2022-
0886.
This proposed AD was prompted by reports of insufficient clearance
between the surrounding structure/skin of the aircraft and select bleed
air ducts that supply the WIPS in the rear fuselage.
[[Page 43463]]
The FAA is proposing this AD to address possible interference between
the high pressure (HP) shroud and the surrounding structures, which
could compromise the HP ducting shroud's capability to provide bleed
air leak routing and result in a bleed air leak being undetected. A
significant undetected bleed air leak could expose the surrounding
structure to heat stress, resulting in reduced structural integrity of
the airplane. See the MCAI for additional background information.
Related Service Information Under 1 CFR Part 51
Bombardier has issued Service Bulletin 700-36-7502, dated October
28, 2020. This service information describes procedures for inspecting
the bleed air duct and surrounding structure for minimum clearance and
damage, and corrective actions, Corrective actions include adjusting
the ductwork if clearance is below the minimum required, and repairing
any damage.
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.
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,
the FAA has been notified of the unsafe condition described in the MCAI
and service information referenced above. The FAA is proposing this AD
because the FAA evaluated all the relevant information and determined
the unsafe condition described previously is likely to exist or develop
on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 8 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
1 work-hours x $85 per hour = $85............................ $1 $86 $688
----------------------------------------------------------------------------------------------------------------
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
Up to 22 work-hours x $85 per hour = $0 $1,870
$1,870...............................
------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this proposed 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
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
Bombardier, Inc.: Docket No. FAA-2022-0886; Project Identifier MCAI-
2022-00261-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by September 6, 2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Bombardier, Inc., Model BD-700-2A12
airplanes, certificated in any category, serial numbers 70006,
70007, 70009 through 70019 inclusive, 70021 through 70029 inclusive,
and 70031.
[[Page 43464]]
(d) Subject

(e) Unsafe Condition
This AD was prompted by reports of insufficient clearance
between the surrounding structure/skin of the aircraft and select
bleed air ducts that supply the wing ice protection system (WIPS) in
the rear fuselage. The FAA is issuing this AD to address possible
interference between the high pressure (HP) shroud and the
surrounding structures, which could compromise the HP ducting
shroud's capability to provide bleed air leak routing and result in
a bleed air leak being undetected. A significant undetected bleed
air leak could expose the surrounding structure to heat stress,
resulting in reduced structural integrity of the airplane.

unless already done.
(g) Required Actions
Within 21 months after the effective date of this AD: Inspect
the affected bleed air ducts and surrounding structure for minimum
clearance and damage (wear or chafing), and do all applicable
corrective actions in accordance with the Accomplishment
Instructions of Bombardier Service Bulletin (SB) 700-36-7502,
October 28, 2020. Do all applicable corrective actions before
further flight.
(h) No Reporting Requirement
Although Bombardier Service Bulletin (SB) 700-36-7502, October
28, 2020, specifies to submit certain information to the
manufacturer, this AD does not include that requirement.
(i) Other FAA AD Provisions
