2023-10329. Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD–700–1A10 and BD–700–1A11 airplanes. This AD was prompted by a report that certain airplane flight manuals (AFMs) contain figures with incorrect performance charts for landing on contaminated runways. This AD requires revising the existing AFM to correct the affected performance charts. The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective June 20, 2023.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of June 20, 2023.

ADDRESSES:

AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA–2023–0164; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this final rule, the mandatory continuing airworthiness information (MCAI), any comments received, and other information. The address for Docket Operations is U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE, Washington, DC 20590.

SUPPLEMENTARY INFORMATION:

Background

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 February 13, 2023 (88 FR 9215). The NPRM was prompted by AD CF–2022–49, dated August 23, 2022, issued by Transport Canada, which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that it was discovered that the thrust reverser correction factors presented in certain AFM performance charts for landing on contaminated runways do not provide sufficient margin for stopping distances in certain conditions. If not corrected, use of the affected performance charts could lead to longitudinal runway excursions. To address the unsafe condition, Transport Canada issued Transport Canada AD CF–2021–35, dated October 26, 2021 (Transport Canada AD CF–2021–35) mandating certain AFM revisions that incorporate changes to the wet and contaminated runway stopping distance data. Transport Canada AD CF–2021–35 corresponds to FAA AD 2022–24–01, Amendment 39–22241 (88 FR 6976, February 2, 2023) (AD 2022–24–01).

Since Transport Canada AD CF–2021–35 was issued, the MCAI states that it was discovered that the mandated AFM changes to Figures 07–35–2 and 07–35–4 are incorrect in certain later revisions of two of the AFMs.

In the NPRM, the FAA proposed to require revising the existing AFM to correct the affected performance charts. The FAA is issuing this AD to address the unsafe condition on these products.

You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–0164.

Discussion of Final Airworthiness Directive

Comments

The FAA received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

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 referenced above. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

The FAA reviewed the following service information, which specifies revised AFM corrections to the performance charts for landing on contaminated runways. These documents are distinct since they apply to different airplane models and configurations.

• Figure 07–35–2 and Figure 07–35–4 of paragraph A., Take-off on Wet Grooved or Wet PFC Runways, of Section 6—Performance, of Supplement 35—Operation on Wet Grooved or Wet Porous Friction Course Runways, of Chapter 7—Supplements of Bombardier Global 6000 Airplane Flight Manual—Publication No. CSP 700–1V, Revision 42, dated May 19, 2022. (For obtaining this section of the Bombardier Global 6000 Airplane Flight Manual—Publication No. CSP 700–1V, use Document Identification No. GL 6000 AFM.)
• Figure 07–35–2 and Figure 07–35–4 of paragraph A., Take-off on Wet Grooved or Wet PFC Runways, of Section 6—Performance, of Supplement 35—Operation on Wet Grooved or Wet Porous Friction Course Runways, of Chapter 7—Supplements of Bombardier Global 5000 Featuring Global Vision Flight Deck Airplane Flight Manual—Publication No. CSP 700–5000–1V, Revision 42, dated May 19, 2022. (For obtaining this section of the Bombardier Global 5000 Featuring Global Vision Flight Deck Airplane Flight Manual—Publication No. CSP 700–5000–1V, use Document Identification No. GL 5000 GVFD AFM.)

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

Estimated Costs for Required Actions

Labor cost	Parts cost	Cost per product	Cost on U.S. operators
1 work-hour × $85 per hour = $85	$0	$85	$17,340

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,

(2) Will not affect intrastate aviation in Alaska, and

(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
