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.

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.

general revisions may be inserted in the AFM, provided the relevant 
information in the general revision is identical to that in Embraer 
AOM TR 40.2 or Embraer AOM TR 19.1, as applicable, and the 
applicable Embraer AOM TR may be removed from the AFM.
