AGENCY:
We propose to supersede
airworthiness directive (AD) 2014–24–
08 that applies to all Rolls-Royce plc
(RR) RB211–535E4–37, RB211–535E4–
B–37, and RB211–535E4–C–37 turbofan
engines with certain low-pressure (LP)
fuel filter-to-high-pressure (HP) fuel
pump tube assemblies, or HP fuel
pump-to-fuel flow governor (FFG) or
FFG-to-HP pump inlet overspill return
tube assemblies and flanged adaptor
installed. AD 2014–24–08 requires
replacing certain LP fuel filter-to-HP
fuel pump tube assemblies. Since we
issued AD 2014–24–08, fuel leaks have
occurred at the flanged joints of the HP
fuel pump-to-FFG tube assembly and
FFG-to-HP pump inlet overspill return
tube assembly. This proposed AD would
retain the original AD requirements and
also require installation of new HP fuel
pump-to-FFG and FFG-to-HP pump

Discussion
On November 20, 2014, we issued AD
2014–24–08, Amendment 39–18041 (79
FR 71308, December 2, 2014), ‘‘AD
2014–24–08,’’ for all RB211–535E4–37,
RB211–535E4–B–37, and RB211–
535E4–C–37 turbofan engines. AD
2014–24–08 expands the applicability to
include the RB211–535E4–C–37
turbofan engine and requires removal
from service of additional part number
(P/N) LP fuel filter-to-HP fuel pump
tube assemblies. AD 2014–24–08
resulted from reports of fuel leaks that
resulted in engine in-flight shutdowns.
We issued AD 2014–24–08 to prevent
loss of fuel supply to the engine, which
could lead to the in-flight shutdown of
one or more engines, loss of thrust
control, and damage to the airplane.
Actions Since AD 2014–24–08 Was
Issued
Since we issued AD 2014–24–08, fuel
leaks have occurred at the flanged joints
of the HP fuel pump-to-FFG and FFGto-HP pump inlet overspill return tube
assemblies. Also since we issued AD
2014–24–08, the European Aviation
Rolls-Royce plc has issued Service
Bulletin (SB) RB.211–73–G230, Revision
3, dated April 8, 2016. The SB describes
a modification (mod 73–G230) and
introduces new HP fuel pump-to-FFG
and FFG-to-HP pump inlet overspill
return tube assemblies with a larger Oring groove on the end adaptor sealing
face. RR has also issued Service Bulletin
SB RB.211–73–H131, Revision 1, dated
September 2, 2014. The SB introduces a
new LP fuel filter-to-HP fuel pump tube
assembly. 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.
FAA’s Determination
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 retain the
original AD requirements and also
require installing new HP fuel pump-toFFG or FFG-to-HP pump inlet overspill
return tube assemblies and flanged
adaptor. This proposed AD changes the
compliance requirement for replacing
the LP fuel filter-to-HP fuel pump tube
assembly adding a not to exceed flight
hour/flight cycle life limit, consistent
with the EASA AD requirements. This
proposed AD would also prohibit reinstallation of earlier HP fuel pump-toFFG and FFG-to-HP pump inlet
overspill return tube assemblies, as well
as LP fuel filter to HP pump tube
assemblies, P/N AE709623–1.
Costs of Compliance
We estimate that this proposed AD
affects 100 engines installed on
airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:

Federal Register / Vol. 82, No. 101 / Friday, May 26, 2017 / Proposed Rules
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 have 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 that the 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.

installed. AD 2014-24-08 requires replacing certain LP fuel filter-to-
HP fuel pump tube assemblies. Since we issued AD 2014-24-08, fuel leaks
have occurred at the flanged joints of the HP fuel pump-to-FFG tube
assembly and FFG-to-HP pump inlet overspill return tube assembly. This
proposed AD would retain the original AD requirements and also require
installation of new HP fuel pump-to-FFG and FFG-to-HP pump inlet
overspill return tube assemblies and flanged adaptor. We are proposing
this AD to correct the unsafe condition on these products.
DATES: We must receive comments on this proposed AD by July 10, 2017.

Discussion
On November 20, 2014, we issued AD 2014-24-08, Amendment 39-18041
(79 FR 71308, December 2, 2014), ``AD 2014-24-08,'' for all RB211-
535E4-37, RB211-535E4-B-37, and RB211-535E4-C-37 turbofan engines. AD
2014-24-08 expands the applicability to include the RB211-535E4-C-37
turbofan engine and requires removal from service of additional part
number (P/N) LP fuel filter-to-HP fuel pump tube assemblies. AD 2014-
24-08 resulted from reports of fuel leaks that resulted in engine in-
flight shutdowns. We issued AD 2014-24-08 to prevent loss of fuel
supply to the engine, which could lead to the in-flight shutdown of one
or more engines, loss of thrust control, and damage to the airplane.
Actions Since AD 2014-24-08 Was Issued
Since we issued AD 2014-24-08, fuel leaks have occurred at the
flanged joints of the HP fuel pump-to-FFG and FFG-to-HP pump inlet
overspill return tube assemblies. Also since we issued AD 2014-24-08,
the European Aviation Safety Agency (EASA) has issued AD 2017-0006,
dated January 10, 2017.
Related Service Information Under 1 CFR Part 51
Rolls-Royce plc has issued Service Bulletin (SB) RB.211-73-G230,
Revision 3, dated April 8, 2016. The SB describes a modification (mod
73-G230) and introduces new HP fuel pump-to-FFG and FFG-to-HP pump
inlet overspill return tube assemblies with a larger O-ring groove on
the end adaptor sealing face. RR has also issued Service Bulletin SB
RB.211-73-H131, Revision 1, dated September 2, 2014. The SB introduces
a new LP fuel filter-to-HP fuel pump tube assembly. 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.
FAA's Determination
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 retain the original AD requirements and also
require installing new HP fuel pump-to-FFG or FFG-to-HP pump inlet
overspill return tube assemblies and flanged adaptor. This proposed AD
changes the compliance requirement for replacing the LP fuel filter-to-
HP fuel pump tube assembly adding a not to exceed flight hour/flight
cycle life limit, consistent with the EASA AD requirements. This
proposed AD would also prohibit re-installation of earlier HP fuel
pump-to-FFG and FFG-to-HP pump inlet overspill return tube assemblies,
as well as LP fuel filter to HP pump tube assemblies, P/N AE709623-1.
Costs of Compliance
We estimate that this proposed AD affects 100 engines installed on
airplanes of U.S. registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Replacement of fuel tube 8.5 work-hours x $85 per $17,800.00 $18,522.50 $1,852,250.00
assemblies. hour = $722.50.

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 have 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 that the 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing airworthiness directive (AD)
2014-24-08, Amendment 39-18041 (79 FR 71308, December 2, 2014), and
adding the following new AD:
