Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2016-0084, dated April 28, 2016 (referred to hereinafter as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    Inspection of in-service Rolls-Royce RB211 Trent 800 engines has 
identified cracking and/or material release from the upper 
bifurcation fairing. This fairing hardware mates to the aeroplane 
thrust reverser upper bifurcation forward fire seal. Both sets of 
hardware create the engine firewall to isolate the engine 
compartment fire zone, which is a firewall feature of the aeroplane 
type design. Damage (missing materials and holes/

[[Page 46001]]

openings) to the upper bifurcation fairing creates a breach of the 
engine fire wall, which may decrease the effectiveness of the engine 
fire detection and suppression systems due to excess fan air 
entering the engine compartment fire zone. This could delay or 
prevent the fire detection and suppression system from functioning 
properly, and can result in an increased risk of prolonged burning, 
potentially allowing a fire to reach unprotected areas of the 
engine, strut and wing.

    Failure to inspect the engine upper bifurcation fairing as proposed 
by this AD could result in failure of the engine fire protection 
system, engine fire, and damage to the airplane.
    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-2016-6692.

Related Service Information

    RR has issued Alert Non-Modification Service Bulletin (NMSB) 
RB.211-72-AJ165, dated March 31, 2016. The NMSB describes procedures 
for inspecting and, if necessary, repairing or replacing the engine 
upper bifurcation fairing.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of the 
United Kingdom 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 and 
service information referenced above. We are proposing this AD because 
we evaluated all information provided by EASA and determined the unsafe 
condition exists and is likely to exist or develop on other products of 
the same type design. This NPRM would require repetitive inspections of 
the engine upper bifurcation fairing and repairing or replacing any 
fairing that fails inspection.

Costs of Compliance

    We estimate that this proposed AD affects 125 engines installed on 
airplanes of U.S. registry. We estimate that it would take about 3.25 
hours to inspect the upper bifurcation fairing do the inspection. We 
estimate that 5 engine fairings will require repair at 8 hours per 
engine and that an additional 5 engine fairings will require 
replacement at 30 hours per engine. We also estimate that materials and 
parts costs would be $500 for each engine. The cost for repair or 
replacement would be about $5,900 or $15,250 respectively. The average 
labor rate is $85 per hour. Based on these figures, we estimate the 
cost of this proposed AD on U.S. operators to be $55,681.

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 to the extent 
that it justifies making a regulatory distinction, 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.

visit, whichever occurs sooner.

Definition

    For the purpose of this AD, a ``shop visit'' is defined as 
induction of an engine into the shop for maintenance involving the 
separation of pairs of major mating engine flanges, except that the 
separation of engine flanges solely for the purposes of 
transportation without subsequent engine maintenance does not 
constitute an engine shop visit.
