Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD) for
Teledyne Continental Motors (TCM)
(formerly Bendix) S–20, S–1200, D–
2000, and D–3000 series magnetos
equipped with impulse coupling
assemblies. That AD currently requires
replacing riveted-impulse coupling
assemblies and snap-ring coupling
assemblies, which are worn beyond
limits, with serviceable riveted-impulse
coupling assemblies or snap-ring
impulse coupling assemblies. This ad
requires a reduced inspection interval
for magnetos with riveted-impulse
coupling assemblies installed on certain
Lycoming engine models. This AD does
not lower the inspection interval for
magnetos with snap-ring impulse

coupling assemblies. This AD also
limits the applicability to certain
Lycoming engine models. This AD
results from data provided by the
manufacturer that shows a need to
reduce the inspection intervals for
riveted-impulse coupling assemblies
used on certain Lycoming engine
models. We are issuing this AD to
prevent failure of the magneto impulse
coupling assembly and possible engine
failure.
This AD becomes effective July
19, 2005. The Director of the Federal
Register previously approved the
incorporation by reference of certain
publications as listed in the regulations
as of July 18, 1996 (61 FR 29934, June
13, 1996).

SUPPLEMENTARY INFORMATION: The FAA
proposed to amend 14 CFR part 39 with
a proposed airworthiness directive (AD).
The proposed AD applies to TCM S–20,
S–1200, D–2000, and D–3000 series
magnetos equipped with impulse
coupling assemblies. We published the
proposed AD in the Federal Register on
December 22, 2004 (69 FR 76632). That
action proposed to require:
• An initial visual inspection of
riveted-impulse coupling assemblies
that have 100 or more hours time-sincenew (TSN) or time-since-last-inspection
(TSLI) on the effective date of the
proposed AD, within 10 hours time-inservice (TIS) after the effective date of
this AD, or
• An initial visual inspection of
riveted-impulse coupling assemblies
that have fewer than 100 hours TSN or
TSLI on the effective date of the
proposed AD, before accumulating 100
hours TSN or TSLI, and
• Repetitive inspections of rivetedimpulse coupling assemblies within
intervals of 100 hours TSLI.
• An initial visual inspection of snapring impulse coupling assemblies that
have 450 or more hours TSN or TSLI on
the effective date of the proposed AD,
within 50 hours TIS after the effective
date of the AD, or
• An initial visual inspection of snapring impulse coupling assemblies that
have fewer than 450 hours TSN or TSLI
before accumulating 500 hours TSN or
TSLI, and
• Repetitive inspections of snap-ring
impulse coupling assemblies within
intervals of 500 hours TSLI.
• Replacing impulse coupling
assemblies that fail the inspection.

ADDRESSES for the location.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Request To Not Change the Eligibility
From the Current AD
One commenter requests that we not
change the eligibility from the current
AD. The commenter states that
experience has shown that the current
AD is preventing failures and there is no
difference between the wear or
reliability of the impulse coupling
assemblies installed on one make and
model of engine, or another.
We do not agree. Responses we
received to the Airworthiness Concern
Sheet and Special Airworthiness
Information Bulletin from owners and
operators, and the manufacturer’s data,
indicate that there is a significant
difference in the wear and reliability of
magnetos installed on Lycoming 540
series engines as compared with other
engines. Based on these responses, we
have appropriately reduced the
inspection interval for magnetos with
riveted-impulse coupling assemblies
installed on Lycoming 540 series
engines.
Request To Not Change From the
Current AD
One commenter states that without
the current AD, owners and operators
will not have the manufacturer’s
recommended maintenance performed,
and safety will suffer.
We do not agree. While a small
percentage of operators may not
voluntarily comply with the
manufacturer’s recommended
maintenance, we anticipate virtually all
will comply. The response to the
Airworthiness Concern Sheet, Special
Airworthiness Information Bulletin, and
manufacturer’s data, indicates the AD is
only needed for the Lycoming 540 series
engines. This action does not negate the
500-hour inspection recommended by
TCM. That inspection is part of the total
inspection program to ensure the
continued airworthiness of the engine.
Therefore, we anticipate that safety will
not suffer.
Addition of Description of Magneto
Model Numbering System
To assist owners and operators, we
have added the description of the
magneto numbering system used for
TCM S–20, S–1200, D–2000, and D–
VerDate jul<14>2003
19:17 Jun 13, 2005
Jkt 205001
3000 series magnetos to the compliance
section of the AD.
Conclusion
We have carefully reviewed the
available data, including the comments
received, and determined that air safety
and the public interest require adopting
the AD with the changes described
previously. We have determined that
these changes will neither increase the
economic burden on any operator nor
increase the scope of the AD.
Costs of Compliance
We estimate that this AD will affect
about 4,200 magnetos installed on
airplanes of U.S. registry. We also
estimate that it will take about 1 work
hour per magneto to perform the
actions, and that the average labor rate
is $65 per work hour. The reduced
inspection interval will require doing
the inspections about four times more
often. Based on these figures, we
estimate the total cost of the AD to U.S.
operators to be $1,092,000.
Special Flight Permits Paragraph
Removed
Paragraph (d) of the current AD, AD
96–12–07, contains a paragraph
pertaining to special flight permits.
Even though this final rule does not
contain a similar paragraph, we have
made no changes with regard to the use
of special flight permits to operate the
airplane to a repair facility to do the
work required by this AD. In July 2002,
we published a new 14 CFR part 39 that
contains a general authority regarding
special flight permits and airworthiness
directives; see Docket No. FAA–2004–
8460, Amendment 39–9474 (69 FR
47998, July 22, 2002). Thus, when we
now supersede ADs we will not include
a specific paragraph on special flight
permits unless we want to limit the use
of that general authority granted in
section 39.23.
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
PO 00000
Frm 00035
Fmt 4700
Sfmt 4700
34337
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 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); 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 by sending a request to us
at the address listed under ADDRESSES.
Include ‘‘AD Docket No. 93-ANE–07AD’’ in your request.

ACTION: Final rule.
AGENCY:
SUMMARY: This final rule will revise
Class E airspace at Wray, CO. New Area
Navigation (RNAV) Global Positioning
System (GPS) Standard Instrument
Approach Procedures (SIAPs) have been
developed at Wray Municipal Airport.
Additional Class E airspace extending
upward from 700 feet above the surface
is necessary for the safety of instrument
flight rules (IFR) aircraft executing these
new SIAPs and transitioning between
the terminal and en route environment.
DATES: 0901 UTC May 12, 2005.

SUPPLEMENTARY INFORMATION:
History
On October 21, 2003, the FAA
published in the Federal Register a
notice of proposed rule making to
modify Class E airspace at Wray, CO (69
FR 32295). New RNAV GPS SIAPs at
Wray Municipal Airport, Wray, CO,
make it necessary to increase the
controlled airspace.
Interested parties were invited to
participate on this rule making
proceeding by submitting written
comments on the proposal to the FAA.
No comments were received. Class E
airspace designations are published in
paragraph 6005 of FAA Order 7400.9M
PO 00000
Frm 00037
Fmt 4700
Sfmt 4700
dated August 30, 2004, and effective
September 16, 2004, which is
incorporated by reference in 14 CFR
part 71.1. The Class E airspace
designations listed in this document
will be published subsequently in that
order.
The Rule
This amendment to 14 CFR part 71
revises Class E airspace at Wray
Municipal Airport, Wray, CO. New
RNAV GPS SIAPs at Wray Municipal
Airport make it necessary to increase
the Class E airspace. This additional
controlled airspace extending upward
from 700 feet or more above the surface
of the earth is for the containment and
safety of IFR aircraft transitioning to/
from the en route environment and
executing these RNAV GPS SIAP
procedures.
The FAA has determined that this
regulation only involved an established
body of technical regulations for which
frequent and routine amendments are
necessary to keep them operationally
current. Therefore, this regulation: (1) Is
not a ‘‘signficant regulatory action’’
under Executive Order 12866; (2) is not
a ‘‘significant rule’’ under DOT
Regulatory Policies and Procedures (44
FR 11034; February 26, 1979); and (3)
does not warrant preparation of a
regulatory evaluation as the anticipated
impact is so minimal. Since this is a
routine matter that will only affect air
traffic procedures and air navigation, it
is certified that this rule, when
promulgated, will not have a significant
economic impact on a substantial
number of small entities under the
criteria of the Regulatory Flexibility Act.

Airworthiness Directives; Teledyne Continental Motors (Formerly
Bendix) S-20, S-1200, D-2000, and D-3000 Series Magnetos
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) for Teledyne Continental Motors (TCM) (formerly Bendix) S-20, S-
1200, D-2000, and D-3000 series magnetos equipped with impulse coupling
assemblies. That AD currently requires replacing riveted-impulse
coupling assemblies and snap-ring coupling assemblies, which are worn
beyond limits, with serviceable riveted-impulse coupling assemblies or
snap-ring impulse coupling assemblies. This ad requires a reduced
inspection interval for magnetos with riveted-impulse coupling
assemblies installed on certain Lycoming engine models. This AD does
not lower the inspection interval for magnetos with snap-ring impulse
coupling assemblies. This AD also limits the applicability to certain
Lycoming engine models. This AD results from data provided by the
manufacturer that shows a need to reduce the inspection intervals for
riveted-impulse coupling assemblies used on certain Lycoming engine
models. We are issuing this AD to prevent failure of the magneto
impulse coupling assembly and possible engine failure.
DATES: This AD becomes effective July 19, 2005. The Director of the
Federal Register previously approved the incorporation by reference of
certain publications as listed in the regulations as of July 18, 1996
(61 FR 29934, June 13, 1996).

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed airworthiness directive (AD). The proposed AD applies
to TCM S-20, S-1200, D-2000, and D-3000 series magnetos equipped with
impulse coupling assemblies. We published the proposed AD in the
Federal Register on December 22, 2004 (69 FR 76632). That action
proposed to require:
An initial visual inspection of riveted-impulse coupling
assemblies that have 100 or more hours time-since-new (TSN) or time-
since-last-inspection (TSLI) on the effective date of the proposed AD,
within 10 hours time-in-service (TIS) after the effective date of this
AD, or
An initial visual inspection of riveted-impulse coupling
assemblies that have fewer than 100 hours TSN or TSLI on the effective
date of the proposed AD, before accumulating 100 hours TSN or TSLI, and
Repetitive inspections of riveted-impulse coupling
assemblies within intervals of 100 hours TSLI.
An initial visual inspection of snap-ring impulse coupling
assemblies that have 450 or more hours TSN or TSLI on the effective
date of the proposed AD, within 50 hours TIS after the effective date
of the AD, or
An initial visual inspection of snap-ring impulse coupling
assemblies that have fewer than 450 hours TSN or TSLI before
accumulating 500 hours TSN or TSLI, and
Repetitive inspections of snap-ring impulse coupling
assemblies within intervals of 500 hours TSLI.
Replacing impulse coupling assemblies that fail the
inspection.
Examining the AD Docket
You may examine the AD Docket (including any comments and service
information), by appointment, between
[[Page 34337]]
8 a.m. and 4:30 p.m., Monday through Friday, except Federal holidays.
See ADDRESSES for the location.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Request To Not Change the Eligibility From the Current AD
One commenter requests that we not change the eligibility from the
current AD. The commenter states that experience has shown that the
current AD is preventing failures and there is no difference between
the wear or reliability of the impulse coupling assemblies installed on
one make and model of engine, or another.
We do not agree. Responses we received to the Airworthiness Concern
Sheet and Special Airworthiness Information Bulletin from owners and
operators, and the manufacturer's data, indicate that there is a
significant difference in the wear and reliability of magnetos
installed on Lycoming 540 series engines as compared with other
engines. Based on these responses, we have appropriately reduced the
inspection interval for magnetos with riveted-impulse coupling
assemblies installed on Lycoming 540 series engines.
Request To Not Change From the Current AD
One commenter states that without the current AD, owners and
operators will not have the manufacturer's recommended maintenance
performed, and safety will suffer.
We do not agree. While a small percentage of operators may not
voluntarily comply with the manufacturer's recommended maintenance, we
anticipate virtually all will comply. The response to the Airworthiness
Concern Sheet, Special Airworthiness Information Bulletin, and
manufacturer's data, indicates the AD is only needed for the Lycoming
540 series engines. This action does not negate the 500-hour inspection
recommended by TCM. That inspection is part of the total inspection
program to ensure the continued airworthiness of the engine. Therefore,
we anticipate that safety will not suffer.
Addition of Description of Magneto Model Numbering System
To assist owners and operators, we have added the description of
the magneto numbering system used for TCM S-20, S-1200, D-2000, and D-
3000 series magnetos to the compliance section of the AD.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the changes described previously.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
We estimate that this AD will affect about 4,200 magnetos installed
on airplanes of U.S. registry. We also estimate that it will take about
1 work hour per magneto to perform the actions, and that the average
labor rate is $65 per work hour. The reduced inspection interval will
require doing the inspections about four times more often. Based on
these figures, we estimate the total cost of the AD to U.S. operators
to be $1,092,000.
Special Flight Permits Paragraph Removed
Paragraph (d) of the current AD, AD 96-12-07, contains a paragraph
pertaining to special flight permits. Even though this final rule does
not contain a similar paragraph, we have made no changes with regard to
the use of special flight permits to operate the airplane to a repair
facility to do the work required by this AD. In July 2002, we published
a new 14 CFR part 39 that contains a general authority regarding
special flight permits and airworthiness directives; see Docket No.
FAA-2004-8460, Amendment 39-9474 (69 FR 47998, July 22, 2002). Thus,
when we now supersede ADs we will not include a specific paragraph on
special flight permits unless we want to limit the use of that general
authority granted in section 39.23.
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 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); 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 by
sending a request to us at the address listed under ADDRESSES. Include
``AD Docket No. 93-ANE-07-AD'' in your request.
