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 reports of the passenger door failing to dampen during opening at regularly scheduled maintenance checks, causing the door to open more rapidly than normal. An investigation found that a contributing factor was erroneous aircraft maintenance manual (AMM) procedures. This proposed AD would prohibit using certain versions of certain aircraft maintenance manual (AMM) tasks for the passenger door. 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 September 26, 2022.

Confidential Business Information

CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this NPRM contain commercial or financial information that is customarily treated as private, that 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 Chirayu Gupta, Aerospace Engineer, Mechanical Systems and Administrative Services Section, FAA, New York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 516-228-7300; email 9-avs-nyaco-cos@faa.gov. 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 Civil Aviation (TCCA), which is the aviation authority for Canada, has issued TCCA AD CF-2021-41, dated November 24, 2021 (TCCA AD CF-2021-41) (also referred to after this as 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 www.regulations.gov by searching for and locating Docket No. FAA-2022-0995.

This proposed AD was prompted reports of the passenger door failing to dampen during opening at regularly scheduled maintenance checks, causing the door to open more rapidly than normal. An investigation found that a contributing factor was erroneous AMM procedures. The AMM tasks related to passenger door maintenance have since been corrected, and only versions of these tasks dated May 19, 2021, or later have the correct procedures. The FAA is proposing this AD to prevent rapid opening of the passenger door, which can result in damage to the door and consequent injury to maintenance personnel. See the MCAI for additional background information.

FAA's Determination


[top] 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 page 49780 described previously is likely to exist or develop on other products of the same type design.

Proposed Requirements of This NPRM

This proposed AD would prohibit using versions issued prior to May 19, 2021 of certain AMM tasks for the passenger door.

Costs of Compliance

The FAA estimates that this proposed AD affects 408 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD:

Labor cost Parts cost Cost per product Cost on U.S. operators
1 work-hour × $85 per hour = $85 $0 $85 $34,680

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.
