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 Ageˆncia Nacional de Aviac ̧a ̃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) lowstage 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 


sradovich on DSK3TPTVN1PROD with RULES
Federal Register / Vol. 81, No. 120 / Wednesday, June 22, 2016 / Rules and Regulations 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, lowstage 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.

Identifier 2016–NE–02–AD; Amendment 39– 

18568; AD 2016–13–04] 

RIN 2120–AA64 

Airworthiness Directives; BRPPowertrain GmbH & Co KG 

Reciprocating Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

BRP-Powertrain GmbH & Co KG Rotax 

912 F2, 912 F3, 912 F4, 912 S2, 912 S3, 

912 S4, 914 F2, 914 F3, and 914 F4 

reciprocating engines. This AD requires 

re-identification of the engine model 

and concurrent modification of the 

aircraft to indicate the maximum 

coolant temperature limit. This AD was 

prompted by a design change 

introduced by the manufacturer that 

relocated the engine cylinder head 

temperature sensor to a different 

location and converted it to a coolant 

temperature sensor. We are issuing this 

AD to prevent exceeding engine coolant 

temperature limits, which could result 

in loss of engine coolant, damage to the 

engine, and loss of control of the 

airplane. 

DATES: This AD becomes effective July 

27, 2016. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication 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 the specified products. The 

NPRM was published in the Federal 

Register on March 18, 2016 (81 FR 

14804). The NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

A design change of the engine cylinder 

heads was introduced by BRP-Powertrain in 

March 2013 which modifies the engine/ 

aircraft interfaces by substituting the 

previous cylinder head temperature (CHT) 

measurement (limit temperature 135 °C/150 

°C) with a coolant temperature (CT) 

measurement (limit temperature 120 °C). 

The design change was communicated on 

15 May 2013 by BRP-Powertrain Service 

Instruction (SI) 912–020R7/914–022R7 

(single document) but was not identified by 

a change of the engine model designation or 

of the engine P/N but only through the 

cylinder head P/N and the position of the 

temperature sensor. 

Consequently, engines with the new 

cylinder heads (installed during production 

or replaced in-service during maintenance) 

may be installed on an aircraft without 

concurrent modification of that aircraft, 

instructions for which should be provided by 

the type certificate (TC) holder or the 

supplemental type certificate (STC) holder, 

as applicable. In this case, the coolant 

temperature with a maximum engine 

operating limit of 120 °C (valid for engines 

operated with water diluted glycol coolant) is 

displayed on a CHT indicator with a typical 

limit marking (red radial/range) of more than 

120 °C. 

You may obtain further information 

by examining the MCAI in the AD 

docket on the Internet at http:// 

www.regulations.gov by searching for 

and locating Docket No. FAA–2016– 

2042. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (81 

FR 14804, March 18, 2016). 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed expect for minor editorial 

changes. We 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 

BRP-Powertrain GmbH & Co KG has 

issued Service Bulletin (SB) SB–912– 

068/SB–914–049 (one document), dated 

April 16, 2015. The service information 

describes procedures for reidentification of the type plate for 

certain BRP-Powertrain GmbH & Co KG 

Rotax 912 and 914 engines. 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 about 

40 engines installed on aircraft of U.S. 

registry. We also estimate that it will 

take about 5 hours per engine to inspect 

and re-identify the type plate. The 

average labor rate is $85 per hour. Based 

on these figures, we estimate the cost of 

this AD on U.S. operators to be $17,000. 

Authority for This Rulemaking
