Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes. This AD was prompted by two in-service incidents of a loss of all air data information in the flight deck. This AD requires a revision of the airplane flight manual (AFM) emergency procedures section to provide procedures to guide the crew on how to stabilize the airplane airspeed and attitude for continued safe flight when a loss of all air data information has occurred in the flight deck. We are issuing this AD to prevent loss of control when a loss of all air data information has occurred in the flight deck. ## The airworthiness directive 1. The authority citation for part 39 continues to read as follows: 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): 2016-17-13 Bombardier, Inc.: Amendment 39-18626; Docket No. FAA-2016-6415; Directorate Identifier 2015-NM-178-AD. ### (a) Effective Date This AD is effective October 5, 2016. ### (b) Affected ADs None. ### (c) Applicability This AD applies to Bombardier, Inc.

Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes. The NPRM published in the Federal Register on May 10, 2016 (81 FR 28768) (“the NPRM”). The NPRM was prompted by two in-service incidents of a loss of all air data information in the flight deck. The NPRM proposed to require a revision of the AFM emergency procedures section to provide procedures to guide the crew on how to stabilize the airplane airspeed and attitude for continued safe flight when a loss of all air data information has occurred in the flight deck. We are issuing this AD to prevent loss of control when a loss of all air data information has occurred in the flight deck. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF-2015-20, dated July 21, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes. The MCAI states: Two in-service incidents have been reported on CL-600-2C10 aeroplanes regarding a loss of all air data information in the cockpit. The air data information was recovered as the aeroplane descended to lower altitudes. An investigation determined that the root cause in both events was high altitude icing (ice crystal contamination). If not addressed, this condition may affect continued safe flight. Due to similarities in the air data systems, such events could happen on all Bombardier CRJ models, CL-600-2B19, CL-600-2C10, CL-600-2D15, CL-600-2D24 and CL-600-2E25. Therefore, the corrective actions for these models will be mandated once their respective Airplane Flight Manual (AFM) revisions become available. This [Canadian] AD mandates the incorporation of AFM procedures to guide the crew to stabilize the aeroplane's airspeed and attitude for continued safe flight. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-6415. ### Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. ### Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. ### Related Service Information Under 1 CFR Part 51 Bombardier, Inc. has issued Section 03-19, “Unreliable Airspeed,” of Chapter 3, “Emergency Procedures,” in the Bombardier CRJ Series Regional Jet Model CL-600-2C10 Airplane Flight Manual CSP B-012, Revision 16A, dated November 6, 2015. The service information describes procedures to guide the crew to stabilize the airplane's airspeed and attitude for continued safe flight when a loss of all air data information has occurred in the flight deck. 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 We estimate that this AD affects 269 airplanes of U.S. registry. We estimate the following costs to comply with this AD: *Estimated costs* | Action | Labor cost | Parts cost | Cost per product | Cost on U.S. operators | | --- | --- | --- | --- | --- | | Revision | 1 work-hour × $85 per hour = $85 | $0 | $85 | $22,865 | ### 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. 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. ### Regulatory Findings We determined that 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. 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. ### Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: ## Affected data sheets (1) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A21EA-1](https://openairdocs.org/tcds/A21EA-1): MHI RJ Aviation ULC; names 1 of 9 models: CL-600-2C10 (Regional Jet Series 700) ## Registered aircraft it may apply to (OpenAirDocs) Matched by airframe and engine model; the AD's applicability may narrow it by serial number, part number or equipment. - Aircraft: 179 (179 by airframe model, 0 by engine model) - Makers: Bombardier 177, Bombardier Aerospace 1, Mhi RJ Aviation ULC 1 Models with the most aircraft: - [Bombardier CL-600-2C10](https://openairdocs.org/model/bombardier-cl-600-2c10): 177 aircraft (airframe model) - [Mhi RJ Aviation ULC CL-600-2C10](https://openairdocs.org/model/mhi-rj-aviation-ulc-cl-600-2c10): 1 aircraft (airframe model) - [Bombardier Aerospace CL-600-2C10](https://openairdocs.org/model/bombardier-aerospace-cl-600-2c10): 1 aircraft (airframe model) All 3 models: https://openairdocs.org/ad/2016-17-13/models.md Every aircraft: https://openairdocs.org/ad/2016-17-13/aircraft.md ## Related documents - [Proposed rule FAA-2016-6415](https://openairdocs.org/proposed/FAA-2016-6415): Notice of proposed rulemaking (NPRM), published May 10, 2016 Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
