Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF- 2015-02, dated January 27, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ''the MCAI''), to correct an unsafe condition for certain Bombardier, Inc. Model DHC-8- 400, -401, and -402 airplanes. The MCAI states: A number of airstair door operation interruptions have been reported. In one case, the airstair door could not be opened. It was found that the airstair door handrail holder bracket was deformed and became lodged into the adjacent wardrobe bulkhead, which prevented the door from opening. On airstair doors with Jetway Compatible option, a deformed handrail holder bracket or a failure of the pin retainer bracket can interfere with the operation of the airstair door and prevent it from opening. The airstair door is classified as an emergency exit. The inability to open an emergency exit could impede evacuation in the event of an emergency. This [Canadian] AD mandates the repetitive inspection of airstair door handrail hardware, and the modification of the handrail stowage hardware. Required actions include applicable corrective actions (replacing or removing brackets, installing lanyards, adjusting pins, and adjusting affected parts of the assembly). 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-2016-9438. Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Service Bulletin 84-52-79, Revision C, dated February 2, 2016. This service information describes procedures for a general visual inspection to detect deformities and cracks of the forward and aft handle holder brackets on the airstair handrail; a detailed visual inspection of the forward and aft pin retainer brackets for the condition of the lanyards and the pins; a check for unobstructed movement of the pin retainer brackets; and rework of the airstair door handrail to prevent damage to the bulkhead and to prevent the door from jamming once the handrails are stowed. 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 and Requirements of This Proposed AD 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 [[Page 91059]] of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance We estimate that this proposed AD affects 82 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Repetitive Inspections......... 1 work-hour x $85 per $0 $85 per inspection $6,970 per hour = $85 per cycle. inspection cycle. inspection cycle. Modification................... 3 work-hours x $85 per 1,556 $1,811............ $148,502. hour = $255. ---------------------------------------------------------------------------------------------------------------- We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. 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 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 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2.
