SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
Honeywell International Inc. TFE731–4,
–4R, –5, –5AR, –5BR, and –5R series
turbofan engines, with interstage turbine
transition (ITT) duct, part number (P/N)
3075292–1; 3075292–3; 3074766–1;
3077063–1; 3075655–1; 3075655–2;
30756599–1; or 30756599–3, installed.
This proposed AD would require
replacing the affected ITT duct with a
serviceable and redesigned ITT duct.
This proposed AD results from reports
of 49 low pressure turbine (LPT) blade
separations. Six of those events resulted
in circumferential failure of the LPT2 or
LPT3 nozzle assembly, leading to
deformation of the ITT duct and
uncontainment of the turbine blades
and fragments of the LPT nozzle
assembly. We are proposing this AD to
prevent uncontainment of turbine
blades and fragments of the LPT nozzle
assembly, which could result in damage
to the airplane.
DATES: We must receive any comments
on this proposed AD by June 3, 2008.
ADDRESSES: Use one of the following

AD.

Discussion
In July 2006, we started receiving
reports of LPT blade separations, which
resulted in circumferential failure of the
LPT2 or LPT3 nozzle assembly. To date,
we have received reports of 49 LPT
blade separations of which 6 of those
events caused spinning of the LPT2 or
LPT3 nozzle assembly. The spinning
can lead to deformation of the ITT duct
and uncontainment of the turbine
blades and fragments of the LPT nozzle
assembly. This condition, if not
corrected, could result in
uncontainment of turbine blades and
fragments of the LPT nozzle assembly,
leading to damage to the airplane.
FAA’s Determination and Requirements
of the Proposed AD
We have evaluated all pertinent
information and identified an unsafe
condition that is likely to exist or
develop on other products of this same
type design. We are proposing this AD,
which would require replacing the
affected ITT duct with a serviceable and
redesigned ITT duct at the next Major
Periodic Inspection of the engine or at
next access of the ITT duct, whichever
occurs first, but not to exceed 2,600
hours time-in-service after the effective
date of the proposed AD. The
serviceable and redesigned ITT duct
will minimize the potential for
uncontained events.
Costs of Compliance
We estimate that this proposed AD
would affect 1,500 engines installed on
airplanes of U.S. registry. We also
estimate that it would take about 4
work-hours per engine to perform the
E:\FR\FM\04APP1.SGM
04APP1
18462
Federal Register / Vol. 73, No. 66 / Friday, April 4, 2008 / Proposed Rules
proposed actions, and that the average
labor rate is $80 per work-hour.
Reworked ITT ducts to the redesign
would cost about $25,000 per engine.
New ITT ducts that are redesigned
would cost about $127,000. We estimate
that 30 engines would require new ITT
ducts. Based on these figures, we
estimate the total cost of the proposed
AD to U.S. operators to be $41,040,000.
Authority for This Rulemaking
ebenthall on PRODPC61 with PROPOSALS
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 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); and
3. Would not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD. You may get a copy
of this summary at the address listed
under ADDRESSES.

PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
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.
VerDate Aug<31>2005
The Proposed Amendment
Under the authority delegated to me
by the Administrator, the Federal
Aviation Administration proposes to
amend 14 CFR part 39 as follows:
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new airworthiness
directive:
Honeywell International Inc. (formerly
AlliedSignal Inc., formerly Garret
Turbine Engine Company): Docket No.
FAA–2008–0264; Directorate Identifier
2008–NE–07–AD.
Comments Due Date
(a) The Federal Aviation Administration
(FAA) must receive comments on this
airworthiness directive (AD) action by June 3,
2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Honeywell
International Inc. TFE731–4, –4R, –5, –5AR,
–5BR, and –5R series turbofan engines, with
interstage turbine transition (ITT) duct, part
number (P/N) 3075292–1; 3075292–3;
3074766–1; 3077063–1; 3075655–1;
3075655–2; 30756599–1; or 30756599–3,
installed. These engines are installed on, but
not limited to, Avions Marcel Dassault
Mystere-Falcon 50 series, Dassault-Aviation
20, 50, 900, MF900 series, Cessna Model 650,
Cessna Citation VII, and Raytheon Corporate
Jets (formerly British Aerospace) Hawker 800
and 850XP series airplanes.
Unsafe Condition
(d) This AD results from reports of 49 low
pressure turbine (LPT) blade separations. Six
of those events resulted in circumferential
failure of the LPT2 or LPT3 nozzle assembly,
leading to deformation of the ITT duct and
uncontainment of the turbine blades and
fragments of the LPT nozzle assembly. We
are issuing this AD to prevent uncontainment
of turbine blades and fragments of the LPT
nozzle assembly, which could result in
damage to the airplane.
Compliance
(e) You are responsible for having the
actions required by this AD performed at the
next Major Periodic Inspection of the engine
or at next access of the ITT duct, whichever
occurs first, but not to exceed 2,600 hours
time-in-service after the effective date of this
AD, unless the actions have already been
done.
Replacement of the ITT Duct
(f) Replace the affected ITT ducts listed by
part number in paragraph (c) of this AD, with
a serviceable and redesigned ITT duct.
