We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-710A2-20 and BR700-710C4-11 turbofan engines. This proposed AD was prompted by reports of deterioration of the intumescent heat resistant paint system on the electronic engine controller (EEC) firebox assembly that was found to be beyond acceptable limits. This proposed AD would require replacement of affected EEC firebox assembly parts with improved parts, which have a more durable paint system. We are proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG 
Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-710A2-20 and 
BR700-710C4-11 turbofan engines. This proposed AD was prompted by

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No. 2017-0198, dated October 10, 2017 (referred to hereinafter as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Occurrences were reported where deterioration of an Electronic 
Engine Controller (EEC) firebox assembly

[[Page 5964]]

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 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.

Related Service Information

    We reviewed RRD Alert Service Bulletin (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, BR700-710C4-11, and BR700-710C4-11/10 engines, respectively.

FAA's Determination

    This product has been approved by the aviation authority of 
Germany, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the European Community, EASA has 
notified us of the unsafe condition described in the MCAI. We are 
proposing this AD because we evaluated all the relevant information and 
determined the unsafe condition described previously is likely to exist 
or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require replacement of affected EEC firebox 
assembly parts with improved parts, which have a more durable paint 
system.

Costs of Compliance

    We estimate that this proposed AD affects 842 engines installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

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

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

    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.
