[Federal Register Volume 81, Number 168 (Tuesday, August 30, 2016)] [Proposed Rules] [Pages 59528-59530] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-20684] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2016-9049; Directorate Identifier 2016-NM-039-AD] RIN 2120-AA64 Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (Embraer) Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Empresa Brasileira de Aeronautica S.A. (Embraer) Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135BJ, -135ER, - 135KE, -135KL, and -135LR airplanes; and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This proposed AD was prompted by reports of main airspeed indication discrepancies during flight; these discrepancies resulted from ice blockages in certain pitot total pressure lines. This proposed AD would require an inspection for tube misalignment of the pitot number 1 and pitot number 2 tube assembly lines, and corrective actions if necessary; installation or replacement (as applicable) of a tube ribbon heater on the pitot number 1 and pitot number 2 tube assembly lines; and revision of the airplane flight manual (AFM) to provide certain procedures and airspeed tables for the flightcrew. We are proposing this AD to detect and correct water accumulating and freezing in the pitot number 1 and pitot number 2 total pressure lines, which could result in erroneous main airspeed indications and consequent reduced ability of the flightcrew to maintain safe flight and landing of the airplane. DATES: We must receive comments on this proposed AD by October 14, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

Discussion Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2016-03-01, effective March 11, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135 airplanes, and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The MCAI states: This [Brazilian] AD results from reports of main airspeed indication discrepancies during flight. The investigation has revealed that Pitot #1 and #2 total pressure line blockage may occur due to water accumulation and freezing during heavy rain conditions. We are issuing this [Brazilian] AD to prevent water accumulation and freezing in the Pitot #1 and Pitot #2 total pressure lines, which could result in erroneous main airspeed indications and reduce the ability of the flight crew to maintain the safe flight and landing of the airplane. 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 . . . . The required actions include a general visual inspection for tube misalignment of pitot number 1 and pitot number 2 tube assembly lines. Corrective actions include replacement of affected pitot tubes with new pitot tubes. The required actions also include installation, or, for certain airplanes, replacement, of a tube ribbon heater on the pitot number 1 and pitot number 2 tube assembly lines, and revision of the AFM to provide certain procedures and airspeed tables for the flightcrew. 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-2016-9049. Related Service Information Under 1 CFR Part 51 Embraer has issued the following service information. Embraer Service Bulletin 145-30-0056, Revision 01, dated March 31, 2014; and Embraer Service Bulletin 145LEG-30-0021, dated March 31, 2014. This service information describes [[Page 59529]] procedures to inspect the pitot pressure tubes for misalignment, install new heaters, and perform repairs. Embraer Temporary Revision (TR) 19.1, dated April 22, 2014, to Volume 1 of the Embraer EMB-145 Aircraft Operations Manual (AOM) AOM-2014135/1542. This service information contains, among other things, the ``Unreliable Airspeed Procedure'' in the Emergency/Abnormal Procedures section and the ``Unreliable Airspeed Tables'' (corresponding to the airplane configuration) in the Performance section. Embraer TR 40.2, dated April 4, 2014, to Volume 1, of the Embraer EMB-145 AOM AOM-145/1114. This service information contains, among other things, the ``Unreliable Airspeed Procedure'' in the Emergency/Abnormal Procedures section and the ``Unreliable Airspeed Tables'' (corresponding to the airplane configuration) in the Performance section. 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 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 these same type designs. Costs of Compliance We estimate that this proposed AD affects 668 airplanes of U.S. registry. We also estimate that it would take up to 5 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $3,254 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be up to $2,457,572, or up to $3,679 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all available costs in our cost estimate. 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.
