SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain 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. The NPRM published in the Federal Register on August 30, 2016 (81 FR 59528) (``the NPRM''). The NPRM was prompted by reports of main airspeed indication discrepancies during flight; these discrepancies resulted from ice blockages in certain pitot total pressure lines. The NPRM proposed to 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 AFM to provide certain procedures and airspeed tables for the flightcrew. We are issuing 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.

Agecircncia Nacional de Aviaccedilatildeo 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

Page 11315

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.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the comment received. The Air Line Pilots Association, International supported the NPRM.

Changes Since the NPRM Was Issued

We have revised this AD to refer to Embraer Service Bulletin 145-

30-0056, Revision 03, dated February 6, 2015. The service information specifies that no additional work is needed if the actions in Embraer Service Bulletin 145-30-0056, Revision 01, dated March 31, 2014; or Revision 02, dated December 10, 2014; have been accomplished. We have revised paragraph (k) of this AD to provide credit for actions done prior to the effective date of this AD using Embraer Service Bulletin 145-30-0056, Revision 01, dated March 31, 2014; or Revision 02, dated December 10, 2014.

Conclusion

We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD with the changes described previously and 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.

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

Embraer has issued the following service information.

Embraer Service Bulletin 145-30-0056, Revision 03, dated February 6, 2015; and Embraer Service Bulletin 145LEG-30-0021, dated March 31, 2014. This service information describes procedures to inspect the pitot pressure tubes for misalignment, install new heaters, and perform repairs. These documents are distinct since they apply to different airplane models.

Embraer Temporary Revision (TR) 19.1, dated April 22, 2014, to Volume 1 of the Embraer Legacy Aircraft Operations Manual (AOM) AOM-135/1542-01. 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-145/1114-01. 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.

Costs of Compliance

We estimate that this AD affects 668 airplanes of U.S. registry.

We also estimate that it will take up to 5 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $3,254 per product. Based on these figures, we estimate the cost of this 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 will enable us to provide cost estimates for the on-condition actions specified in this AD.

According to the manufacturer, some of the costs of this 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 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.
