[Federal Register Volume 82, Number 146 (Tuesday, August 1, 2017)] [Rules and Regulations] [Pages 35638-35641] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-15807] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0250; Directorate Identifier 2016-NM-158-AD; Amendment 39-18976; AD 2017-15-16] RIN 2120-AA64 Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (Embraer) AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135ER, - 135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This AD was prompted by a report of airplanes with modified gust lock levers that prevented the thrust lever's full excursion, thus limiting the engine power. This AD requires replacing a certain gust lock lever. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective September 5, 2017. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of September 5, 2017.

SUPPLEMENTARY INFORMATION: [[Page 35639]] Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135ER, -135KE, -135KL, -135LR, - 145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The NPRM published in the Federal Register on April 20, 2017 (82 FR 18590) (``the NPRM''). The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2016-07-01, dated July 18, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135ER, -135KE, - 135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The MCAI states: ANAC was informed about occurrences in which airplanes that incorporated SB 145-27-0115, which changes the Gust Lock lever format, managed to takeoff, or performed [rejected take-offs] RTOs, in such a configuration that the Gust Lock lever prevented the thrust levers full excursion, thus limiting the engine power to about 70% of the nominal takeoff power. Analyses and simulations conducted by the manufacturer confirmed this as a possible scenario in case some verification procedures prior to and during takeoff, for whatever reason, are not properly performed. After evaluation, the conclusion was that the incorporation of SB 145-27-0115 would take away an important tactile cue regarding the thrust levers position, which, in a timely manner, would alert the crew of an improper takeoff configuration. During takeoffs, or attempts thereof, in such condition, the airplane would have a reduced performance, which would increase the required takeoff distance or the RTO distance, and reduce the airplane capacity to clear obstacles. Since this condition may occur in other airplanes of the same type and affects flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with this [Brazilian] AD in the indicated time limit. Required actions include replacing a certain gust lock lever. 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-2017- 0250. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM and the FAA's response to that comment. Request To Revise the Compliance Time Air Line Pilots Association, International (ALPA) requested that the compliance time in the NPRM be revised. ALPA stated that since the Embraer service information was published 19 months prior, operators have been provided ample time to perform inspections to determine whether a corrective action is required. ALPA commented that, therefore, it is in partial support of the NPRM and suggested an inspection compliance time of 12 months or 2,500 flight hours after the effective date of the AD, and a repair compliance time of 24 months or 5,000 hours after the effective date of the AD. We disagree with the commenter's request. In developing an appropriate compliance time, we considered the safety implications, parts availability, and normal maintenance schedules for timely accomplishment of inspecting and replacing the gust lock lever. Further, we arrived at the proposed compliance time with operator and manufacturer concurrence. Since the actions specified in the Brazilian AD and service information are not mandatory in the U.S., the FAA must issue a final rule to mandate those actions in order to address the identified unsafe condition. In consideration of all of these factors, we determined that the compliance time, as proposed, represents an appropriate time in which the gust lock lever can be inspected and replaced in a timely manner within the fleet, while still maintaining an adequate level of safety. We have not changed this AD in this regard. Conclusion We reviewed the relevant data, considered the comments received, 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 We have reviewed Embraer Service Bulletin 145-27-0126, dated October 6, 2015. This service information describes procedures for replacement of a certain gust lock lever for one with an alternative format. We have also reviewed Embraer Service Bulletin 145-27-0115, Revision 03, dated October 5, 2015. This service information describes modification procedures involving replacement of the gust lock lever with a new gust lock lever enabling both engine thrust levers to be advanced at the same angle as that of the electromechanical gust lock lever. 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 668 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspection......................... 1 work-hour x $85 per hour $0 $85 $56,780 = $85. ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need this replacement: [[Page 35640]] On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replacement................................ 1 work-hour x $85 per hour = $85... $6,315 $6,400 ---------------------------------------------------------------------------------------------------------------- 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2017-15-16 Empresa Brasileira de Aeronautica S.A. (Embraer): Amendment 39-18976; FAA-2017-0250; Directorate Identifier 2016-NM- 158-AD. (a) Effective Date This AD is effective September 5, 2017. (b) Affected ADs None. (c) Applicability This AD applies to all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135ER, -135KE, -135KL, -135LR, -145, -145ER, - 145MR, -145LR, -145XR, -145MP, and -145EP airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 27, Flight controls. (e) Reason This AD was prompted by a report of airplanes with modified gust lock levers that performed take-offs or rejected take-offs (RTOs), in such a configuration that the gust lock lever prevented the thrust lever's full excursion, thus limiting the engine power to about 70% of the nominal take-off power. We are issuing this AD to prevent incorrect configuration of the gust lock lever, which could reduce the airplane's performance during take-offs or attempted take-offs, increase the required take-off distance or the RTO distance, and reduce the airplane's capacity to clear obstacles. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Inspection Within 5,000 flight hours or 24 months after the effective date of this AD, whichever occurs first: Check the airplane maintenance records to determine whether the actions specified in Embraer Service Bulletin 145-27-0115 have been done. If the records review is inconclusive, inspect the engine control box assembly against the Accomplishment Instructions of Embraer Service Bulletin 145-27-0115, Revision 03, dated October 5, 2015, to determine whether the actions specified in Embraer Service Bulletin 145-27-0115 have been done. (h) Corrective Action If the check or inspection required by paragraph (g) of this AD indicates that the actions in Embraer Service Bulletin 145-27-0115 have been done: Within 5,000 flight hours or 24 months after the effective date of this AD, whichever occurs first, replace the gust lock lever, in accordance with the Accomplishment Instructions of Embraer Service Bulletin 145-27-0126, dated October 6, 2015.
