Airworthiness Directives; Embraer S.A. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Embraer S.A. Model ERJ 170 airplanes; and all Embraer S.A. Model ERJ 
190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW 
airplanes. This AD was prompted by reports of cracks in certain engine 
low-stage bleed check valves. This AD requires replacing the air 
management system (AMS) controller operation program of the AMS 
controller processor boards, and replacing the current low-stage bleed 
check valve and associated seals. We are issuing this AD to prevent 
failure of the low-stage bleed check valve; simultaneous failures of 
both low-stage bleed check valves could result in a dual engine in-
flight shutdown.

DATES: This AD is effective July 27, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 27, 
2016.

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 all Embraer S.A. Model ERJ 
170 airplanes; and all Embraer S.A. Model ERJ 190-100 STD, -100 LR, -
100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. The NPRM published 
in the Federal Register on November 30, 2015 (80 FR 74720) (``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 2015-02-02, effective March 6, 2015 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Embraer S.A. 
Model ERJ 170 airplanes; and all Embraer S.A. Model ERJ 190-100 STD, -
100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. The MCAI 
states:

    This [Brazilian] AD was prompted by reports of cracks in some 
engine low-stage bleed check valves having part number (P[/]N) 
1001447-6. Further analysis has determined that if a new (zero hour) 
low-stage bleed check valve P/N 1001447-6 is installed in an 
airplane already equipped with the Air Management System (AMS) 
controller processor boards containing the AMS Controller 
Operational Program version Black Label 13, or a later version, 
premature cracking on the petals of the low-stage bleed check valve 
is not expected to occur. We are issuing this [Brazilian] AD to 
prevent the possibility of a dual engine in-flight shutdown due to 
low-stage bleed check valve failure.

    The unsafe condition is failure of the low-stage bleed check valve; 
simultaneous failures of both low-stage bleed check valves could result 
in a dual engine in-flight shutdown. The required action is replacement 
of the AMS controller operation program of the AMS controller processor 
boards, and replacement of the low-stage bleed check valves and 
associated seals. 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-2015-6542.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Request To Authorize Operators To Install Used Overhauled Valves

    An anonymous commenter requested that we revise the NPRM to 
authorize operators to install used valves that have been overhauled by 
the manufacturer or other authorized 14 CFR part 145 repair station. 
The commenter stated that the historical service records required to 
determine the serviceability of used valves installed on airplanes are 
not required by 14 CFR 91.417 and are generally not available. 
According to the commenter, this limits the ability of operators of 
Embraer Model ERJ 170 airplanes to adequately determine the service 
history of valves that were previously installed on Embraer Model ERJ 
190 airplanes, and whether the installation of a used valve will meet 
compliance with the

[[Page 40481]]

requirements of paragraph (j)(1) of the proposed AD.
    We disagree to revise this AD to authorize operators to install 
used valves that have been overhauled. A valve that has been used on a 
Model ERJ 190 airplane without the AMS controller operational program 
version Black Label 13 or later version has been subjected to hydraulic 
pressures above the valve's structural limits. The damage to the valve 
could be undetectable, and the valve can therefore experience premature 
cracking. However, as is stated in paragraph (i) of this AD, low-stage 
bleed check valves having P/N 1001447-6 that can be demonstrated with 
logged hours only on Model ERJ-170 airplanes and/or on Model ERJ-190 
airplanes equipped with the AMS controller operational program version 
Black Label 13, or a later version, can be used instead of new ones 
(zero-hour). We have made no changes to this AD in this regard.

Request To Revise Wording of the Unsafe Condition

    Embraer requested that we revise the unsafe condition in the NPRM 
to indicate that a single valve failure cannot result in a dual engine 
failure. Embraer stated that a dual engine failure can occur only in 
the event of simultaneous failures of both valves on both engines on 
the same flight.
    For the reasons stated by Embraer, we agree to include the 
requested phrasing in all appropriate locations in this final rule.

Request To Revise the Applicability

    United Technologies Aerospace Systems (UTAS) requested that we 
revise the applicability of the NPRM to include Model ERJ ``195 
airplanes'' and limit the applicability for Model ERJ 170 airplanes 
(including Model ERJ ``175 airplanes'') to those ``requiring 
replacement check valves.''
    We disagree to revise the applicability of this AD. There is a 
difference between the commercial designation and the model designation 
on the type certificate data sheet (TCDS): ``ERJ 175'' is the 
commercial designation of Model ERJ 170-200 airplanes on the TCDS, and 
``ERJ 195'' is the commercial designation of Model ERJ 190-200 
airplanes on the TCDS. We use the model designation on the TCDS to 
define the applicability of ADs.
    Although this AD is applicable to Model ERJ 190 and Model ERJ 170 
airplanes, the only requirement for Model ERJ 170 airplanes is included 
in paragraph (j)(1) of this AD, which is related to installation of 
used low-stage bleed check valves having P/N 1001447-6 on Model ERJ 170 
airplanes. As noted in the NPRM, ANAC is considering future rulemaking 
to include a similar requirement. We have made no changes to this AD in 
this regard.

Request To Clarify the Reason for the NPRM

    UTAS requested that we revise paragraph (e), ``Reason,'' of the 
proposed AD to specify that cracks were found only on check valve P/N 
1001447-6 on Model ERJ 190 airplanes.
    Although we agree that cracks may have been found only on check 
valve P/N 1001447-6 on Model ERJ 190 airplanes, we disagree to revise 
paragraph (e), ``Reason,'' of this AD. The unsafe condition of this AD 
is not limited to Model ERJ 190 airplanes since the check valves may 
also be installed on Model ERJ 170 airplanes. We have made no changes 
to 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 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 Service Bulletin 190-36-0023, Revision 03, dated 
September 24, 2014; and Service Bulletin 190-21-0041, Revision 02, 
dated July 30, 2013. The service information describes procedures for 
replacing the engine low-stage bleed check valves. Embraer Service 
Bulletin 190-21-0041, Revision 02, dated July 30, 2013, also describes 
procedures for replacing the AMS controller operation program of the 
AMS controller processor boards. 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 197 airplanes of U.S. registry.
    We also estimate that it will take about 4 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 $638 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $192,666, or $978 per product.

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.
