Discussion
We propose to adopt an AD for certain
CFE CFE738–1–1B model turbofan
engines with HPC impeller, part number
(P/N) 6079T77P07 or P/N 6079T77P09
installed. This proposed AD was
prompted by a quality escape for HPC
impellers made from forgings with
nonconforming material grain size. This
condition, if not corrected, could result
in failure of the HPC impeller, damage
to the engine, and damage to the
airplane.

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 require
removal of affected HPC impellers from
service and replacement with a part
eligible for installation.
Costs of Compliance
We estimate that this proposed AD
affects 176 engines installed on
airplanes of U.S. registry.

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, and
(4) Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities

Discussion
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD No. 2015–
PO 00000
Frm 00030
Fmt 4702
Sfmt 4702
0092, dated May 26, 2015, to correct an
unsafe condition for Airbus Model
AS332C, AS332C1, AS332L, AS332L1,
AS332L2, and EC225LP helicopters
with certain part-numbered IGB fairings
installed. EASA advises of occurrences
involving separation of the angle section
of the IGB fairing from the IGB fairing
gutter, which caused interference with
the tail rotor (T/R) inclined drive shaft.
EASA states that this condition, if not
detected and corrected, could lead to
failure of the T/R drive shaft, loss of the
T/R drive, and consequent reduced
control of the helicopter. To address this
condition, EASA issued a series of ADs
to require repetitive inspections of the
IGB fairing and its attachment supports
and other corrective actions. According
to EASA, reports of cracks and
separation of the gutter continued to
occur. EASA superseded its previous
ADs and issued AD No. 2011–0189–E,
dated September 29, 2011, to require
additional inspections of the IGB fairing
and attachment supports.
After EASA issued AD No. 2011–
0189–E, Airbus Helicopters developed a
new IGB fairing, part number (P/N)
332A24–0322–00, which is a one-piece
full composite part that integrates a
gutter. EASA then superseded AD No.
2011–0189–E and issued AD No. 2015–
0092, retaining the inspection
requirements but requiring installation
of the new composite IGB fairing as
terminating action for the inspections.
FAA’s Determination
These helicopters have been approved
by the aviation authority of France and
are approved for operation in the United
States. Pursuant to our bilateral
agreement with France, EASA, its
technical representative, has notified us
of the unsafe condition described in its
AD. We are proposing this AD because
we evaluated all known relevant
information and determined that an
unsafe condition is likely to exist or
develop on other products of the same
type design.

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, 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
