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.
    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

[[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 <a href="http://www.regulations.gov">http://www.regulations.gov</a> 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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> 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.
    <bullet> 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.
    <bullet> 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.
    <bullet> 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.
