Background

TCCA, which is the aviation authority for Canada, has issued TCCA AD CF-2022-11, dated March 17, 2022 (TCCA AD CF-2022-11) (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. TCCA AD CF-2022-11 supersedes TCCA AD CF-2021-44, dated December 2, 2021.

This AD was prompted by a dual-engine automatic shutdown on landing experienced by a Model BD-500-1A11 airplane. The crew successfully stopped the airplane with degraded systems and functions. An investigation is ongoing to determine the root cause, but preliminary findings of this event indicate that erroneous uncontrolled high thrust (UHT) detection can occur above 16,000 feet when the thrust lever is manually and abruptly? 1 moved towards the idle position. Based on the preliminary findings from the ongoing investigation, and as a result of extensive subsequent communication with TCCA and Airbus Canada to determine the extent and urgency of the identified unsafe condition, the FAA is issuing this AD, which corresponds to TCCA AD CF-2022-11. TCCA AD CF-2022-11 is an interim action that includes revising the existing AFM by incorporating new AFM operating procedures to mitigate any UHT event-which can result in, for example, stall on the runway or loss of braking on landing-that may occur until the investigation is complete. The FAA is issuing this AD to address an erroneous UHT detection in flight, which would result in engine shutdown on landing with or without indications or crew alerting system messages displayed before landing, and, in the case of an automatic dual-engine shutdown upon landing, could result in loss of braking, loss of control of the airplane, and a runway excursion. See the MCAI for additional background information.

Footnotes:

1 ?See definition of abrupt throttle movement in Figure 1 of TCCA AD CF-2022-11.

Related Service Information Under 1 CFR Part 51

TCCA AD CF-2022-11 specifies procedures for revising the existing AFM to incorporate a new normal procedure for low-altitude descent check (below 16,000 feet) and revised non-normal procedures for "L THROTTLE FAIL" and "R THROTTLE FAIL." These procedures, which are specified in paragraph D of TCCA AD CF-2022-11, replace the interim procedures introduced by TCCA AD CF-2021-44; those interim procedures are specified in paragraphs A and B of TCCA AD CF-2022-11. 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

These products have been approved by the aviation authority of another country and are 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 described above. The FAA is issuing this AD after determining that the unsafe condition described previously is likely to exist or develop on other products of these same type designs.

Requirements of This AD

This AD requires accomplishing actions specified in paragraph D of TCCA AD CF-2022-11 described previously.

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, TCCA AD CF-2022-11 is incorporated by reference in this AD. This AD requires compliance with certain actions in TCCA AD CF-2022-11 through that incorporation. Service information required by TCCA AD CF-2022-11 for compliance will be available at www.regulations.gov by searching for and locating Docket No. FAA-2022-0990 after this AD is published.

FAA's Justification and Determination of the Effective Date

Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq. ) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for "good cause," finds that those procedures are "impracticable, unnecessary, or contrary to the public interest." Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause.


[top] An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies forgoing notice and comment prior to adoption of this rule because an erroneous UHT detection in flight would result in engine shutdown on landing with or without indications or CAS messages displayed before landing. An automatic dual-engine shutdown upon landing could result in loss of braking, loss of control of the airplane, and a runway excursion. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the page 50562 public interest pursuant to 5 U.S.C. 553(b)(3)(B).

In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forgo notice and comment.

Regulatory Flexibility Act (RFA)

The requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required.

Costs of Compliance

The FAA estimates that this AD affects 69 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

Labor cost Parts cost Cost per product Cost on U.S. operators
1 work-hour × $85 per hour = $85 $0 $85 $5,865

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:

(1) Is not a "significant regulatory action" under Executive Order 12866, and

(2) Will not affect intrastate aviation in Alaska.
