This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: It has been found the possibility of elevator mass balance fasteners becoming slack under certain conditions. The loose of at least two fasteners may lead to an unbalance condition, which may induce flutter on airplane elevators. ## The airworthiness directive Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: 1. The authority citation for part 39 continues to read as follows: 2. The FAA amends § 39.13 by adding the following new AD: 2009-24-14 Empresa Brasileira de Aeronáutica S.A. (EMBRAER): Amendment 39-16108; Docket No. FAA-2009-0870; Directorate Identifier 2009-CE-049-AD. ### (a) Effective Date (a) This airworthiness directive (AD) becomes effective January 4, 2010. ### (b) Affected ADs (b) None. ### (c) Applicability (c) This AD applies to EMB-500 airplanes, serial numbers 50000005, 50000006, 50000008 through 50000036, 50000038 through 50000041, 50000043 through 50000046, 50000048, and 50000053, certificated in any category. ### (d) Subject (d) Air Transport Association of America (ATA) Code 27: Flight Controls. ### (e) Reason (e) The mandatory continuing airworthiness information (MCAI) states: It has been found the possibility of elevator mass balance fasteners becoming slack under certain conditions. The loose of at least two fasteners may lead to an unbalance condition, which may induce flutter on airplane elevators. The MCAI requires replacement of the nuts of the right and left elevators mass balance fasteners. ### (f) Actions and Compliance (f) Unless already done, do the following actions: (1) Within the next 30 days after January 4, 2010 (the effective date of this AD), replace the nuts of the right-hand (RH) and left-hand (LH) elevators' mass balance fasteners with new ones of self-locking type bearing part number (P/N) MS21043-4.

On January 4, 2010, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD. ### Addresses You may examine the AD docket on the Internet at http://www.regulations.gov or in person at Document Management Facility, U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC 20590. ### For further information contact Karl Schletzbaum, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4146; fax: (816) 329-4090. ### Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on September 21, 2009 (74 FR 48028). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: It has been found the possibility of elevator mass balance fasteners becoming slack under certain conditions. The loose of at least two fasteners may lead to an unbalance condition, which may induce flutter on airplane elevators. The MCAI requires replacement of the nuts of the right and left elevators mass balance fasteners. ### 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 available data and determined that air safety and the public interest require adopting the AD as proposed. ### Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a note within the AD. ### Costs of Compliance We estimate that this AD will affect 25 products of U.S. registry. We also estimate that it will take about 2 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $150 per product. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $7,750 or $310 per product. ### 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 this AD: (1) Is not a “significant regulatory action” under Executive Order 12866; (2) Is not a “significant rule” under 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. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD Docket. ### Examining the AD Docket You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. ## Affected data sheets (1) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A59CE](https://openairdocs.org/tcds/A59CE): Embraer S.A.; names 1 of 1 models: EMB-500 ## 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: 221 (221 by airframe model, 0 by engine model) - Makers: Embraer-Empresa Brasileira De 107, Embraer Executive 72, Embraer 42 Models with the most aircraft: - [Embraer-Empresa Brasileira De EMB-500](https://openairdocs.org/model/embraer-empresa-brasileira-de-emb-500): 107 aircraft (airframe model) - [Embraer Executive EMB-500](https://openairdocs.org/model/embraer-executive-emb-500): 72 aircraft (airframe model) - [Embraer EMB-500](https://openairdocs.org/model/embraer-emb-500): 42 aircraft (airframe model) All 4 models: https://openairdocs.org/ad/2009-24-14/models.md Every aircraft: https://openairdocs.org/ad/2009-24-14/aircraft.md No proposed rule in this release led to it.
