Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2018-15, dated June 6, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or "the MCAI"), to correct an unsafe condition for certain Bombardier, Inc., Model BD-500-1A10 and BD-500-1A11 airplanes. The MCAI states:
Multiple events of dislodged cargo compartment blow-out panels have been reported in-service. It was determined that these events were caused by baggage impacting the cargo panel cage, or the cargo compartment liner below the cargo panel cage, during baggage loading and unloading on the ground, or during flight due to shifting luggage.
Dislodged cargo compartment blow-out panels create openings in the forward and aft cargo compartments. In the event of a cargo compartment fire, these unintended openings in the forward and aft cargo compartments would provide a path for smoke, fire, and Halon to enter the adjacent equipment bays, flight deck, and passenger cabin, which could delay smoke detection in the forward and aft cargo compartments and result in the forward and aft cargo compartments not being able to maintain Halon concentration required for fire suppression. The cargo compartment fire may become uncontrollable if this condition is not corrected.
This AD mandates repetitive [detailed] inspections of the affected forward and aft cargo compartment blow-out panels, and reporting of inspection findings where dislodged blow-out panels have been found [and re-installation of dislodged blow-out panels].

Related Service Information Under 1 CFR Part 51
Bombardier has issued C Series Data Module BD500-A-J50-10-01-01AAA-310B-A, "Forward and aft cargo compartment blow-out panels-Visual check," Issue 002, dated May 16, 2018. This service information describes procedures for an inspection for any dislodged blow-out panel in the forward and aft cargo compartments.
Bombardier has issued C Series Data Module BD500-A-J50-10-01-00AAA-521A-A, "Decompression panels dislodging-Return to basic configuration," Issue 002, dated May 16, 2018. This service information describes procedures for re-installation of dislodged forward and aft cargo compartment blow-out panels.
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.
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 our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition 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 require accomplishing the actions specified in the service information described previously. This proposed AD also would require sending positive inspection results to Bombardier.
Costs of Compliance
We estimate that this proposed AD affects 21 airplanes of U.S. registry. We estimate 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 | $1,785 |
We estimate the following costs to do any necessary on-condition action that would be required based on the results of any required actions. We have no way of determining the number of aircraft that might need this on-condition action:
| Labor cost | Parts cost | Cost per product |
|---|---|---|
| 2 work-hours × $85 per hour = $170 | $0 | $170 |
We estimate that it would take about 1 work-hour per product to comply with the proposed on-condition reporting requirement in this proposed AD. The average labor rate is $85 per hour. Based on these figures, we estimate the cost of reporting the inspection results on U.S. operators to be $85 per product.
Paperwork Reduction Act
[top] 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
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.
We are 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.
This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division.
Regulatory Findings
We 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. Is not a "significant rule" under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
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
1. The authority citation for part 39 continues to read as follows:
Authority:
49 U.S.C. 106(g), 40113, 44701.
§?39.13 [Amended]
2. The FAA amends §?39.13 by adding the following new airworthiness directive (AD):
Bombardier, Inc.: Docket No. FAA-2018-0799; Product Identifier 2018-NM-117-AD.
(a) Comments Due Date
We must receive comments by November 5, 2018.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Bombardier, Inc., airplanes, certificated in any category, identified in paragraphs (c)(1) and (c)(2) of this AD.
(1) Model BD-500-1A10 airplanes, serial numbers 50001 and subsequent, equipped with blow-out panel part number D762213-503, D762216-505, or D762209-503.
(2) Model BD-500-1A11 airplanes, serial numbers 55001 and subsequent, equipped with blow-out panel part number D762213-503, D762216-505, or D762209-503.
(d) Subject
Air Transport Association (ATA) of America Code 50, Cargo and accessory compartment.
(e) Reason
This AD was prompted by reports of dislodged cargo compartment blow-out panels. We are issuing this AD to address this condition, which could result in openings in the forward and aft cargo compartments. In the event of a cargo compartment fire, these unintended openings in the forward and aft cargo compartments would provide a path for smoke, fire, and Halon to enter the adjacent equipment bays, flight deck, and passenger cabin, which could delay smoke detection in the forward and aft cargo compartments and result in the forward and aft cargo compartments not being able to maintain Halon concentration required for fire suppression. The cargo compartment fire may become uncontrollable if this condition is not addressed, which could result in the loss of controllability of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified, unless already done.
(g) Repetitive Inspections of the Forward and Aft Cargo Compartment Blow-Out Panels and Re-Installation
Within 7 days or 50 flight cycles, whichever occurs first, after the effective date of this AD, do a detailed inspection for any dislodged blow-out panel in the forward and aft cargo compartments, in accordance with C Series (Bombardier) Data Module BD500-A-J50-10-01-01AAA-310B-A, "Forward and aft cargo compartment blow-out panels-Visual check," Issue 002, dated May 16, 2018. Re-install all dislodged forward and aft cargo compartment blow-out panels before further flight, in accordance with C Series (Bombardier) Data Module BD500-A-J50-10-01-00AAA-521A-A, "Decompression panels dislodging-Return to basic configuration," Issue 002, dated May 16, 2018. Thereafter, at intervals not to exceed 100 flight cycles, repeat the detailed inspection for any dislodged blow-out panel in the forward and aft cargo compartments.
(h) Reporting
If any blow-out panel in the forward or aft cargo compartments is found dislodged during any inspection required by paragraph (g) of this AD, at the applicable time specified in paragraph (h)(1) or (h)(2) of this AD, report findings to the Bombardier customer response center (CRC) via email: crc_cseries@aero.bombardier.com. Reportable findings include the airplane serial number on which any dislodged blow-out panel was found, the date of inspection, and the part number and location of each dislodged blow-out panel.
(1) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.
(2) If the inspection was done before the effective date of this AD: Submit the report within 30 days after the effective date of this AD.
