Strasse 6, D–78713 Schramberg.
(iii) You may remove the propeller hub and
return as specified in paragraph (e)(1)(ii) of
this AD at any time prior to accumulating 15
hours TIS on the propeller to terminate the
inspection requirement of paragraph (e)(1)(i)
of this AD.
(2) For propellers with 15 or more hours
TIS as of the effective date of this AD: Prior
to further flight, remove the propeller hub
and return to the propeller manufacturer for
inspection and overhaul. Send the propeller
hub along with the propeller hours time-inservice (TIS) to Technoflug
Leichtflugzeugbau GmbH, Dr. Kurt Steim
Strasse 6, D–78713 Schramberg.
(3) For all sailplanes: With the propeller
removed, the powered sailplane can
temporarily be used in the sailplane
configuration. If the engine battery (at the
steel frame between the seats) is not
removed, a new weight and balance report is
not necessary. After the inspection and
overhaul of the propeller hub is done, the
propeller must be reinstalled.
FAA AD Differences
mstockstill on PROD1PC61 with RULES
Note: This AD differs from the MCAI and/
or service information as follows:
(1) The MCAI did not have a required
action if cracks were found during the
inspection. This AD requires the propeller
hub to be overhauled by the manufacturer
before further flight if cracks are found.
(2) The MCAI allowed continued flight
over the 15 hour propeller TIS limit (up to
the annual inspection) if the propeller TIS
was less than 15 hours as of the effective date
of this AD. For propellers at or less than 15
hours TIS, the FAA is requiring the propeller
hub to be overhauled by the manufacturer
upon the accumulation of 15 hours TIS or
prior to further flight if cracks are found,
whichever occurs first.
(3) The service information allows for the
pilot to perform the inspection and the
removal and reinstallation of the propeller.
By FAA regulation (14 CFR part 43), the pilot
is not allowed to do these actions and an
appropriately-rated mechanic must perform
these actions.
(4) The MCAI incorporates the service
information. We have modified the
procedures in the service information as
stated above and incorporated the procedures
into this AD. This AD only references the
service information.
Other FAA AD Provisions
(f) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, Standards Staff,

64106; telephone: (816) 329–4130; fax: (816)
329–4090, has the authority to approve
AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19.
(2) Airworthy Product: For any
requirement in this AD to obtain corrective
actions from a manufacturer or other source,
use these actions if they are FAA-approved.
Corrective actions are considered FAA-

approved if they are approved by the State
of Design Authority (or their delegated
agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any
reporting requirement in this AD, under the
provisions of the Paperwork Reduction Act
(44 U.S.C. 3501 et seq.), the Office of
Management and Budget (OMB) has
approved the information collection
requirements and has assigned OMB Control
Number 2120–0056.

ACTION: Final rule; request for
comments.
AGENCY:
The FAA is adopting a new
airworthiness directive (AD) for RollsRoyce Corporation (RRC) AE 2100D3
turboprop engines. This AD requires
removing certain part number (P/N)
compressor cone shaft assemblies at a
new reduced cyclic life limit of 5,000
engine cycles. This AD results from lowcycle-fatigue testing and analysis of
certain P/N compressor cone shaft
assemblies, by RRC. We are issuing this
AD to prevent uncontained failure of the
compressor cone shaft assembly, leading
to engine shutdown and damage to the
airplane.
DATES: This AD becomes effective
December 29, 2006.
We must receive any comments on
this AD by February 12, 2007.

SUPPLEMENTARY INFORMATION: RRC
conducted low-cycle-fatigue testing, and
strength and life analysis, of compressor
cone shaft assemblies, P/Ns 23050728,
23070729, and 23076017. The study
concluded that these compressor cone
shaft assemblies have a lower fatigue
life than originally calculated. This
condition, if not corrected, could result
in uncontained failure of the
compressor cone shaft assembly, leading
to engine shutdown and damage to the
airplane.
ADDRESSES:
FAA’s Determination and Requirements
of This AD
Although no airplanes that are
registered in the United States use these
RRC AE 2100D3 turboprop engines, the
possibility exists that the engines could
be used on airplanes that are registered
in the United States in the future. The
unsafe condition described previously is
likely to exist or develop on other AE
2100D3 turboprop engines of the same
type design. We are issuing this AD to
prevent uncontained failure of the
compressor cone shaft assembly, leading
to engine shutdown and damage to the
airplane. This AD requires removing
compressor cone shaft assemblies, P/Ns
23050728, 23070729, and 23076017, at
a new reduced cyclic life limit of 5,000
engine cycles. The original cyclic life
limit was 20,000 engine cycles. RRC
will revise Chapter 5 of the maintenance
E:\FR\FM\14DER1.SGM
14DER1
Federal Register / Vol. 71, No. 240 / Thursday, December 14, 2006 / Rules and Regulations
manual to show the new reduced cyclic
life limit of 5,000 engine cycles.
FAA’s Determination of the Effective
Date
Since there are currently no domestic
operators of this engine model, notice
and opportunity for public comment
before issuing this AD are unnecessary.
A situation exists that allows the
immediate adoption of this regulation.
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 us any
written relevant data, views, or
arguments regarding this AD. Send your
comments to an address listed under

2006–NE–42–AD’’ in the subject line of
your comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of the rule that might suggest a
need to modify it.
We will post all comments we
receive, without change, to https://

substantive verbal contact with FAA
personnel concerning this AD. Using the

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
VerDate Aug<31>2005
15:47 Dec 13, 2006
Jkt 211001
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 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 the 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); and
3. 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.
We prepared a summary of the costs
to comply with this AD and placed it in
the AD Docket. You may get a copy of
this summary at the address listed
