14 CFR Part 39

[Docket No. FAA-2011-0942; Directorate Identifier 2011-NE-29-AD;
Amendment 39-16840; AD 2011-21-17]
RIN 2120-AA64

Airworthiness Directives; General Electric Company Turboshaft
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all
General Electric Company (GE) CT7-8A, CT7-8A1, CT7-8E, and CT7-8F5
turboshaft engines with a fuel filter differential pressure switch,
part number (P/N) TD028VF0H7Y5 (part of the fuel filter assembly, P/N

4110T53P06) installed. This AD requires daily visual inspections of the
fuel filter differential pressure switch for fuel leaks and for
excessive cracking of the switch mounting flanges due to stress-
corrosion. This AD also requires the installation of a collar kit over
the fuel filter differential pressure switch as terminating action to
the daily inspections. This AD was prompted by reports of 47 fuel
filter differential pressure switches found with stress-corrosion
cracking of the mounting flanges. We are issuing this AD to prevent
unrecoverable in-flight engine shutdown, engine bay fire due to fuel
leakage, and forced landing or accident.

DATES: This AD is effective November 17, 2011.
    The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of November 17,
2011.
    We must receive comments on this AD by December 19, 2011.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:

Discussion

    Since March of 2011, we have received reports of 47 fuel filter
differential pressure switches found with cracked mounting flanges. The
pressure switch, P/N TD028VF0H7Y5, is part of the fuel filter assembly,
P/N 4110T53P06. Investigation has revealed that the two cap screws
securing the switch to the fuel filter assembly, apply a bending stress
to the aluminum mounting flanges of the switch. This bending stress,
coupled with contaminants in the operating environment, can lead to
stress-corrosion cracking of the mounting flanges on the switch. This
condition, if not corrected, could result in unrecoverable in-flight
engine shutdown, engine bay fire due to fuel leakage, and forced
landing or accident.

Relevant Service Information

    We reviewed GE Alert Service Bulletin (ASB) No. CT7-8-S/B 73-A0007,
dated July 8, 2011, and ASB No. CT7-8-S/B 73-A0008, dated August 17,
2011. The service information describes procedures for performing daily
visual inspections of the fuel filter differential pressure switch for
fuel leaks and for excessive cracking of the switch mounting flanges,
and for installing a collar kit over the fuel filter differential
pressure switch as terminating action to the daily inspections. The
collar kit will retain the pressure switch from separating from the
filter head of the fuel filter assembly due to cracks in the pressure
switch flanges, and will prevent the pressure switch from leaking.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires accomplishing the actions specified in the service
information described previously.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because about
20% of the affected fuel filter differential pressure switches in
service have been found cracked. Many of the affected engines are used
on Sikorsky S-92 helicopters in offshore applications. Therefore, we
find that notice and opportunity for prior public comment are
impracticable and that good cause exists for making this amendment
effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, we invite you to send any written data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include the docket number FAA-2011-0942 and
Directorate Identifier 2011-NE-29-AD at the beginning of your comments.
We specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.

Costs of Compliance

    We estimate that this AD will affect 80 engines installed on
helicopters of U.S. registry. We also estimate that it would take about
0.1 work-hour per engine to perform a daily visual inspection and about
0.1 hour to install a collar over the fuel filter differential pressure
switch. The average labor rate is $85 per work-hour. Required parts
would cost about $200 per engine. Based on these figures, we estimate
the total cost of the AD for one visual inspection and installation of
the collar to U.S. operators to be $17,360.

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

    This AD will not have federalism implications under Executive Order
13132. This AD will 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 this AD:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Is not a ``significant rule'' under 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.
