(2) Install a FADEC software version 

eligible for installation. 

(h) Installation Prohibition 

Within 90 days after the effective date of 

this AD, do not operate any engine with 

FADEC software, version 9.3.2.4 or earlier, 

installed. 

(i) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, ECO Branch, FAA, has 

the authority to approve AMOCs for this AD, 

if requested using the procedures found in 14 

CFR 39.19. In accordance with 14 CFR 39.19, 

send your request to your principal inspector

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 RRD BR700–710A2–20 

and BR700–710C4–11 turbofan engines. 

The NPRM published in the Federal 

Register on February 12, 2018 (83 FR 

5963). The NPRM was prompted by 

reports of deterioration of the 

intumescent heat resistant paint system 

on the EEC firebox assembly that was 

found to be beyond acceptable limits. 

The NPRM proposed to require 

replacement of affected EEC firebox 

assembly parts with improved parts, 

which have a more durable paint 

system. We are issuing this AD to 

address the unsafe condition on these 

products. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2017– 

0198, dated October 10, 2017 (referred 

to after this as ‘‘the MCAI’’), to address 

the unsafe condition on these products. 

The MCAI states: 

Occurrences were reported where 

deterioration of an Electronic Engine 

Controller (EEC) firebox assembly 

intumescent heat resistant paint system was 

found to be beyond acceptable limits. 

Subsequent investigation determined that 

lack of paint adhesion, due to incorrect 

surface preparation during manufacturing, 

had caused this deterioration. 

This condition, if not corrected, could 

reduce the fire protection capability of the 

EEC firebox, possibly leading to reduced 

control of an engine during engine fire, 

engine overspeed and release of high-energy 

debris, resulting in damage to, and/or 

reduced control of, the aeroplane. 

To address this potential unsafe condition, 

RRD issued Alert SB SB–BR700–73– 

A101977, SB–BR700–73–A101981 and SB– 

BR700–73–A101985 to provide modification 


daltland on DSKBBV9HB2PROD with RULES
45336 Federal Register / Vol. 83, No. 174 / Friday, September 7, 2018 / Rules and Regulations 

instructions introducing improved new or 

reworked EEC firebox assembly parts, which 

have a more durable paint system. 

For the reason described above, this AD 

requires replacement of affected EEC firebox 

assembly parts with improved parts. 

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–2017– 

1050. 

Comments 

We gave the public the opportunity to 

participate in developing this final rule. 

The following presents the comment 

received on the NPRM and the FAA’s 

response to this comment. 

Request To Revise Compliance Time 

RRD requested that we align the 

compliance time of this AD with EASA 

AD 2017–0198, dated October 10, 2017, 

and RRD Alert Service Bulletins (ASBs) 

SB–BR700–73–A101977, SB–BR700– 

73–A101981 and SB–BR700–73– 

A101985. RRD suggested that we revise 

the compliance time of the FAA AD to 

meet the end date of the RRD ASBs, 

which is January 31, 2021. 

We agree. The proposed compliance 

time of 6 months in the NPRM was an 

error. We revised the compliance time 

for performance of the required actions 

of this AD to a timeframe consistent 

with the EASA AD and the RRD ASBs. 

The revised compliance time requires 

performance of the required actions 

within 28 months after the effective date 

of this AD. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting this 

final rule with the change 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 

addressing 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 final rule. 

Related Service Information 

We reviewed RRD ASB SB–BR700– 

73–A101977, Revision 3, dated July 10, 

2017; RRD ASB SB–BR700–73– 

A101981, Revision 3, dated July 10, 

2017; and RRD ASB SB–BR700–73– 

A101985, Revision 3, dated July 10, 

2017. The service information describes 

procedures for installing new or 

reworked EEC firebox assembly parts for 

BR700–710A2–20 and BR700–710C4–11 

turbofan engines, which includes 

BR700–710C4–11/10 turbofan engines. 

Costs of Compliance 

We estimate that this AD affects 842 

engines installed on airplanes of U.S. 

registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S.

EEC firebox assembly replacement ............... 2.5 work-hours × $85 per hour = $212.50 ..... $4,900 $5,112.50 $4,304,725 

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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to engines, propellers, and 

associated appliances to the Manager, 

Engine and Propeller Standards Branch, 

Policy and Innovation Division. 

Regulatory Findings 

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 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.
