2023-02781. Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by a report of a lateral offset observed on the head-up display (HUD) of several airplanes between the synthetic vision system (SVS) and actual runway due to mechanical misalignment of the HUD during manufacturing and assembly. This AD requires revising the existing airplane flight manual (AFM) to prohibit steep approach landing (SAL) and enhanced flight vision system (EFVS) operations. This AD also requires calibrating the HUD. The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective March 17, 2023.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of March 17, 2023.

ADDRESSES:

AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2022-0684; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

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-700-2A12 airplanes. The NPRM published in the Federal Register on June 21, 2022 (87 FR 36783). The NPRM was prompted by AD CF-2021-36, dated November 1, 2021, issued by Transport Canada, which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that during production activities, a lateral offset was observed on the HUD of several airplanes between the SVS and actual runway. An investigation determined the cause of the offset to be mechanical misalignment of the HUD during manufacturing and assembly. This offset, if not corrected, will create an incorrect airplane reference display on the HUD, which could lead to excessive deviation during landing. This could particularly affect SAL or EFVS operations.

In the NPRM, the FAA proposed to require revising the existing AFM to prohibit SAL and EFVS operations, and calibrating the HUD. 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-2022-0684.

Discussion of Final Airworthiness Directive

Comments

The FAA received a comment from Executive Jet Management, Inc. (EJM). The following presents the comment received on the NPRM and the FAA's response.

Request To Provide Means To Allow Later-Approved Service Information

EJM noted that ADs for Bombardier airplanes often involve approval for alternative methods of compliance (AMOCs) because the required AFMs or other service information becomes outdated before the AD becomes effective. Because of the increasing number of Bombardier ADs that require these AMOCs, EJM expressed concern over the burden associated with the AMOC process. EJM recognized that the FAA cannot allow the future use of service information that is not available when the AD is published. EJM noted that an AD issued by the European Union Aviation Safety Agency (EASA) typically states that the use of later-approved revisions of the required service information is acceptable for compliance, and that the corresponding FAA AD refers to that EASA AD for the requirements. EJM requested a similar process for ADs for Bombardier airplanes, adding that this process would streamline their workload and enhance safety.

The FAA partially agrees with the request. The FAA agrees with referencing the latest AFM revisions in this AD. Certain sections of Bombardier Global 7500 AFM, Publication No. CSP 700-7000-1 cited in the NPRM have been revised, as described under “Related Service Information under 1 CFR part 51” in this final rule. The AFM sections are modified to revise calculations for certain performance data, and therefore do not add any additional work to the proposed requirements of the NPRM. The FAA revised paragraphs (g)(1) through (3) of this AD to require the revised service information. This AD also provides credit for use of the documents that were identified in the NPRM, as specified in revised paragraph (i) of this AD.

The FAA disagrees with adding a statement that allows using later-approved revisions of the AFM sections specified in the Related Service Information under 1 CFR part 51 section of this AD, as the FAA would need to determine their effect to the AD. Further, the FAA is required by Office of the Federal Register (OFR) regulations for approval of materials incorporated by reference, as specified in 1 CFR 51.1(f), to either publish the service document contents as part of the actual AD language; or submit the service document to the OFR for approval as referenced material, in which case the FAA may only refer to such material in the text of an AD. However, it is not necessary to include a statement in this final rule that allows the use of later-approved revisions of the AFM. Paragraph (g) of this AD requires revising the existing AFM to “include the information in” the specified sections of the AFM. As long as the information included in the AFM is identical to “the information in” those AFM sections, operators may use means other than the specified AFM revisions to comply with the requirement.

Regarding the IBR the MCAI process, the FAA must have permission from the design approval holder to post in the AD docket the service information required for compliance with the MCAI. At this time, the FAA has not received Bombardier's permission for the “IBR the MCAI” process. Without this permission, the FAA cannot IBR the MCAI.

Additional Changes Made to This AD

The FAA has revised paragraph (h) of this AD to allow the HUD calibration to be done using Bombardier Service Bulletin 700-34-7521, Revision 03, dated July 27, 2021, or Bombardier Service Bulletin 700-34-7521, Revision 04, dated December 6, 2021; and Bombardier Service Bulletin 700-34-7523, Revision 01, dated December 8, 2021; as applicable. This change more closely reflects the revisions specified in paragraph B. of the MCAI. The FAA has also removed paragraph (i)(1)(iv) of this AD (paragraph (i)(4) of the proposed AD), and reidentified the subsequent paragraph accordingly, because Bombardier Service Bulletin 700-34-7521, Revision 03, dated July 27, 2021, is now specified in paragraph (h) of this AD. Further, paragraphs (i)(1)(i) through (iv) have been clarified to specify which documents are and are not incorporated by reference in this AD.

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, considered the comment received, 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, and any other changes described previously, 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

Bombardier has issued the following documents to prohibit SAL and EFVS operations until the HUD has been calibrated.

• Section 6., Service Bulletins, Chapter 1—Introduction, Bombardier Global 7500 AFM, Publication No. CSP 700-7000-1, Revision 18, dated August 18, 2022.
• Supplement 7—Enhanced Flight Vision System (EFVS) Operations, Chapter 7—Supplements, Bombardier Global 7500 AFM, Publication No. CSP 700-7000-1, Revision 18, dated August 18, 2022.
• Supplement 20—Steep Approaches with Published Glidepath Angles from 4.5 to 5.5 Degrees, Chapter 7—Supplements, Bombardier Global 7500 AFM, Publication No. CSP 700-7000-1, Revision 18, dated August 18, 2022.

(For obtaining this material in the Bombardier Global 7500 AFM, Publication No. CSP 700-7000-1, use Document Identification No. GL 7500 AFM.)

Bombardier has issued the following documents, which specify procedures for calibrating the HUD (and second HUD if installed). The procedures include an inspection of the HUD mounting brackets and sill beams for damage and contamination ( e.g., drill shavings and adhesive) of the mating surfaces and injection holes, an inspection for voids in the structural adhesive, and applicable corrective actions. Corrective actions include replacing damaged brackets and backfilling voids with structural adhesive. These documents are distinct since they apply to different airplane configurations.

• Bombardier Service Bulletin 700-34-7521, Revision 03, dated July 27, 2021.
• Bombardier Service Bulletin 700-34-7521, Revision 04, dated December 6, 2021.
• Bombardier Service Bulletin 700-34-7523, Revision 01, dated December 8, 2021.

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.

Other Related Service Information

Earlier revisions of Bombardier Service Bulletins 700-34-7521 and 700-34-7523 included a typographical error on the metric values on the “External Target Board” table. This error was corrected in Bombardier Service Bulletin 700-34-7521, Revision 03, dated July 27, 2021; Bombardier Service Bulletin 700-34-7521, Revision 04, dated December 6, 2021; and Bombardier Service Bulletin 700-34-7523, Revision 01, dated December 8, 2021. This error is further described in the Retroactive Action section in these service bulletins. The FAA has determined that the earlier revisions are acceptable for compliance with the requirements of this AD under certain conditions in their entirety if imperial values were used. However, if the metric values specified in the earlier revisions were used, the HUD calibration is not considered completed for the purposes of Supplement 7—Enhanced Flight Vision System (EFVS) Operations, and Supplement 20—Steep Approaches with Published Glidepath Angles from 4.5 to 5.5 Degrees, of Chapter 7—Supplements, of the Bombardier Global 7500 AFM, Publication No. CSP 700-7000-1, until retroactive actions are also done as specified in paragraph (i) of this AD.

Costs of Compliance

The FAA estimates that this AD affects 40 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators
HUD calibration	39 work-hours (for 36 airplanes with 1 HUD) or 108 work-hours (for 4 airplanes with 2 HUDs) × $85 per hour = $3,315 (1 HUD) or $9,180 (2 HUDs)	$7,400 per HUD	$10,715 (1 HUD) or $23,980 (2 HUDs)	$385,740 (36 airplanes with 1 HUD); $95,920 (4 airplanes with 2 HUDs).
AFM revision	1 work-hour × $85 per hour	$0	$85	$3,400.

The FAA estimates that replacement brackets would cost up to $1,200 (per HUD) if required for any on-condition corrective actions in this AD. The FAA has received no definitive data on which to base the work-hour estimates for this replacement. The FAA has no way of determining the number of airplanes that might need this on-condition action.

The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators.

Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a currently valid OMB Control Number. The OMB Control Number for this information collection is 2120-0056. The time for public reporting for this collection of information, including reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information, is provided in the Costs of Compliance section already described. All responses to this collection of information are mandatory. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524.

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.
