Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by the discovery that existing maintenance tasks do not detect the potential failure of the passenger door detent mechanism because there is no procedure for inspecting the passenger door locking mechanism. This proposed AD would require revising the maintenance or inspection program, as applicable, to require use of a certain aircraft maintenance manual (AMM) task during accomplishment of a specified maintenance check. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; 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 Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11
airplanes. This proposed AD was prompted by the discovery that existing
maintenance tasks do not detect the potential failure of the passenger
door detent mechanism because there is no procedure for inspecting the
passenger door locking mechanism. This proposed AD would require
revising the maintenance or inspection program, as applicable, to
require use of a certain aircraft maintenance manual (AMM) task during
accomplishment of a specified maintenance check. The FAA is proposing
this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by February 5,
2024.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this NPRM. Submissions containing CBI should be sent to

Any commentary that the FAA receives which is not
specifically designated as CBI will be placed in the public docket for
this rulemaking.
Background
Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD CF-2023-25, dated April 13, 2023 (Transport
Canada AD CF-2023-25) (also referred to after this as the MCAI), to
correct an unsafe condition on certain Bombardier, Inc., Model BD-700-
1A10 and BD-700-1A11 airplanes. The MCAI states time limited
maintenance check (TLMC) item 52-11-00-201, ``Passenger Door Mechanism
Functional Test,'' does not detect potential failure of the passenger
door detent mechanism. Associated aircraft maintenance manual (AMM)
task 52-11-00-720-801, ``Passenger Door Mechanism Functional Test,''
does not provide a procedure for inspecting the passenger door locking
mechanism.
The FAA is proposing this AD to address potential failures of the
uninspected detents (external handle detent and torque tube detent) in
combination with a failure of the tension pot spring assembly. The
unsafe condition, if not addressed, could result in the main passenger
door opening during unpressurized flight.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-2397.

This service information specifies new inspection instructions for
the passenger door detent mechanisms.
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 ADDRESSES.
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 this State of Design Authority,
it has notified the FAA of the unsafe condition described in the MCAI
and service information referenced above. The FAA is issuing this NPRM
after determining that 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 the use of AMM Task 52-11-00-720-
801, dated August 16, 2022, during accomplishment of TLMC Item 52-11-
00-201. It also prohibits using AMM Task 52-11-00-720-801, dated 19 May
2022 or earlier.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 482 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed 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
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-2023-2397; Project Identifier MCAI-
2023-00601-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by February 5, 2024.
(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 (S/
Ns) 9002 through 60065 inclusive.
(d) Subject
Air Transport Association (ATA) of America Code 52, Doors.
(e) Unsafe Condition
This AD was prompted by the discovery that existing maintenance
tasks do not detect the potential failure of the passenger door
detent mechanism because there is no procedure for inspecting the
passenger door locking mechanism. The FAA is proposing
[[Page 88543]]
this AD to address potential failures of the uninspected detents
(external handle detent and torque tube detent) in combination with
a failure of the tension pot spring assembly. The unsafe condition,
if not addressed, could result in the main passenger door opening
during unpressurized flight.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Maintenance or Inspection Program Task Restrictions
Within 30 days after the effective date of this AD, revise the
existing maintenance or inspection program, as applicable, to use
Aircraft Maintenance Manual (AMM) Task 52-11-00-720-801,
``Functional Test of the Passenger Door Mechanism,'' as specified in
the applicable AMMs identified in figure 1 to paragraph (g) of this
AD, when performing time limited maintenance check item 52-11-00-
201.
