Transport Canada Civil Aviation (TCCA), which is the airworthiness authority for Canada, notified us that an unsafe condition may exist on Bombardier Model DHC-8-102, DHC-8-103, DHC-8-106, DHC-8-201, DHC-8-202, DHC-8-301, DHC-8-311, and DHC-8-315 airplanes equipped with a cockpit door electronic strike system installed in accordance with supplemental type certificate (STC) SA03-70 issue No. 1 or issue No. 2 (which is equivalent to STC ST02014NY). TCCA advises that the electronic strike system of the cockpit door is defective. (STC SA03-70 issue No. 3 incorporates the enhanced security measures for these doors.) Defective equipment, if not corrected, could compromise flight safety. Transport Canada Civil Aviation (TCCA) issued Canadian airworthiness directive CF-2008-26R1, dated August 15, 2008 (referred to after this as the Mandatory Continuing Airworthiness Information or “MCAI”) to ensure the continued airworthiness of these airplanes in Canada.
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 referenced above. We are issuing 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.
Therefore, we are issuing AD 2008-26-03 to prevent failure of the electronic strike system, which could compromise flight safety. This AD requires modifying the electronic strike system of the cockpit door in accordance with a method approved by the Manager, New York Aircraft Certification Office (ACO), FAA.
None of the airplanes affected by this action are on the U.S. Register. Therefore, providing notice and opportunity for public comment is unnecessary before this AD is issued, and this AD may be made effective in less than 30 days after it is published in the
This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the
We will post all comments we receive, without change, to
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
We have 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 the 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); 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.
