Executive Order 13132 encourages
independent regulatory agencies to
consider the impact of their actions on
state and local interests. NCUA, an
independent regulatory agency as
defined in 44 U.S.C. 3502(5), voluntarily
complies with the executive order to
adhere to fundamental federalism
principles. This proposed rule 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. NCUA has
determined that this proposed rule does
not constitute a policy that has
federalism implications for purposes of
the executive order.

ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for certain
Cessna Aircraft Company Model 500,
501, 550, 551, S550, 560, 560XL, and
650 airplanes. This proposed AD was
prompted by multiple reports of smoke
and/or fire in the tailcone caused by
sparking due to excessive wear of the
brushes in the air conditioning (A/C)
motor. This proposed AD would require
an inspection to determine the
accumulated hours on certain A/C drive
motor assemblies; repetitive
replacement of the brushes in the drive
motor assembly, or as an option to the
brush replacement, deactivation of the
air conditioner; and return of replaced
brushes to Cessna. We are proposing
this AD to prevent the brushes in the
A/C motor from wearing down beyond
their limits, which could result in the
rivet in the brush contacting the
commutator causing sparks and
consequent fire and/or smoke in the
tailcone with no means to detect or
extinguish the fire and/or smoke.
DATES: We must receive comments on
this proposed AD by November 13,
2012.
SUMMARY:
You may send comments,

Discussion
We have received more than 10
reports of smoke/fire (three reports of
fire) in the tailcone of Cessna Aircraft
Company Model 525, 550, and 560
airplanes, where investigation revealed
brushes had worn beyond their limits

C compressor motors. The motor
assembly is located in the airplane
tailcone where flammable fluids in the
form of fuel lines and hydraulics are
present. There is no fire detection or
extinguishing system in the tailcone. We
are proposing this AD to prevent the
brushes in the air conditioning motor
from wearing down beyond their limits,
which could result in the rivet in the
brush contacting the commutator
causing sparks and consequent fire and/
or smoke in the tailcone with no means
to detect or extinguish the fire and/or
smoke.
The subject part, P/N 1134104–1 A/C
compressor motors, might also be
installed on Model 500, 501, 551, S550,
560XL, and 650 airplanes. Therefore,
those Model 500, 501, 551, S550,
560XL, and 650 airplanes might be
subject to the unsafe condition revealed
on Model 525, 550, and 560 airplanes.

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.
59147
Proposed AD Requirements
This proposed AD would require an
inspection to determine if certain A/C
compressor motors are installed, an
inspection of the A/C compressor hour
meter that has P/N 1134104–1 or
1134104–5 A/C compressor motors
installed, repetitive replacement of the
brushes, or deactivation of the A/C
system with installation of a placard
prohibiting use of the A/C system until
replacement of the brushes as an option
to the brush replacement. This proposed
AD would also require, when the
brushes are replaced, reporting of
aircraft information related to the
replacement of the brushes and sending
the replaced motor brushes to Cessna
Aircraft Company for two replacement
cycles.
Interim Action
We consider this proposed AD
interim action. The reporting data
required by this proposed AD will
enable us to obtain better insight into
brush wear. The reporting data will also
indicate if the replacement intervals we
established are adequate. After we
analyze the reporting data received, we
might consider further rulemaking.
Model 525 airplanes are not subject to
this proposed AD. We are currently
considering requiring similar actions for
these airplanes.
Costs of Compliance
We estimate that this proposed AD
will affect 1,987 airplanes of U.S.
registry.
We estimate the following costs to
comply with this proposed AD:
ESTIMATED COSTS
Action
Labor cost
Parts cost
Inspection, drive motor

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

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,

(g) Part Number (P/N) Inspection
The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
Within 30 days or 10 flight hours after the
effective date of this AD, whichever comes
first: Inspect the A/C compressor motor to
determine whether P/N 1134104–1 or P/N
1134104–5 is installed. A review of airplane
maintenance records is acceptable in lieu of
this inspection if the part number of the A/
C compressor motor can be conclusively
determined from that review.
PART 39—AIRWORTHINESS
DIRECTIVES
(h) Inspection of Compressor Hour Meter
and Maintenance Records
1. The authority citation for part 39
continues to read as follows:
If during the inspection required by
paragraph (g) of this AD, any A/C compressor
motor is found having P/N 1134104–1 or P/
N 1134104–5: Within 30 days or 10 flight
hours after the effective date of this AD,
whichever occurs first, determine the hour
reading on the A/C compressor hour meter as
specified in paragraphs (h)(1) and (h)(2) of
this AD:
(1) Inspect the number of hours on the A/
C compressor hour meter; and
(2) Check the airplane logbook for any
entry for replacing the A/C compressor motor
brushes with new brushes, or for replacing
the compressor motor or compressor
condenser module assembly (pallet) with a
motor or assembly that has new brushes;
(i) If the logbook contains an entry for
replacement of parts as specified in
paragraph (h)(2) of this AD, determine the
number of hours on the A/C compressor
motor brushes by comparing the number of
hours on the compressor motor since
replacement and use this number in lieu of
the number determined in paragraph (h)(1) of
this AD; or
(ii) If through the logbook check you
cannot positively determine the number of
hours on the A/C compressor motor brushes
as specified in paragraph (h)(2) of this AD,
use the number of hours on the A/C
compressor hour meter determined in
paragraph (h)(1) of this AD or presume the
brushes have over 500 hours time-in-service.

Airworthiness Directives; Cessna Aircraft Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Cessna Aircraft Company Model 500, 501, 550, 551, S550, 560,
560XL, and 650 airplanes. This proposed AD was prompted by multiple
reports of smoke and/or fire in the tailcone caused by sparking due to
excessive wear of the brushes in the air conditioning (A/C) motor. This
proposed AD would require an inspection to determine the accumulated
hours on certain A/C drive motor assemblies; repetitive replacement of
the brushes in the drive motor assembly, or as an option to the brush
replacement, deactivation of the air conditioner; and return of
replaced brushes to Cessna. We are proposing this AD to prevent the
brushes in the A/C motor from wearing down beyond their limits, which
could result in the rivet in the brush contacting the commutator
causing sparks and consequent fire and/or smoke in the tailcone with no
means to detect or extinguish the fire and/or smoke.
DATES: We must receive comments on this proposed AD by November 13,
2012.
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:
Comments Invited
We invite you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under the ADDRESSES section. Include ``Docket No. FAA-2012-1001;
Directorate Identifier 2012-NM-020-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this proposed AD. We
will consider all comments received by the closing date and may amend
this proposed AD because of those comments.
We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this proposed AD.
Discussion
We have received more than 10 reports of smoke/fire (three reports
of fire) in the tailcone of Cessna Aircraft Company Model 525, 550, and
560 airplanes, where investigation revealed brushes had worn beyond
their limits on the part number (P/N) 1134104-1 A/
[[Page 59147]]
C compressor motors. The motor assembly is located in the airplane
tailcone where flammable fluids in the form of fuel lines and
hydraulics are present. There is no fire detection or extinguishing
system in the tailcone. We are proposing this AD to prevent the brushes
in the air conditioning motor from wearing down beyond their limits,
which could result in the rivet in the brush contacting the commutator
causing sparks and consequent fire and/or smoke in the tailcone with no
means to detect or extinguish the fire and/or smoke.
The subject part, P/N 1134104-1 A/C compressor motors, might also
be installed on Model 500, 501, 551, S550, 560XL, and 650 airplanes.
Therefore, those Model 500, 501, 551, S550, 560XL, and 650 airplanes
might be subject to the unsafe condition revealed on Model 525, 550,
and 560 airplanes.
Relevant Service Information
We have reviewed the following service information:
Subject 4-11-00, Replacement Time Limits, of Chapter 4,
Airworthiness Limitations, Revision 10, dated April 23, 2012, of the
Cessna Model 550, -0801 and On Maintenance Manual.

Maintenance Manual.
Subject 4-11-00, Replacement Time Limits, of Chapter 4,
Airworthiness Limitations, Revision 7, dated April 23, 2012, of the
Cessna Model S550 Maintenance Manual.
The service information describes procedures for replacement of
life-limited components including P/N 1134104-1 A/C compressor motor
brushes.
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 an inspection to determine if
certain A/C compressor motors are installed, an inspection of the A/C
compressor hour meter that has P/N 1134104-1 or 1134104-5 A/C
compressor motors installed, repetitive replacement of the brushes, or
deactivation of the A/C system with installation of a placard
prohibiting use of the A/C system until replacement of the brushes as
an option to the brush replacement. This proposed AD would also
require, when the brushes are replaced, reporting of aircraft
information related to the replacement of the brushes and sending the
replaced motor brushes to Cessna Aircraft Company for two replacement
cycles.
Interim Action
We consider this proposed AD interim action. The reporting data
required by this proposed AD will enable us to obtain better insight
into brush wear. The reporting data will also indicate if the
replacement intervals we established are adequate. After we analyze the
reporting data received, we might consider further rulemaking.
Model 525 airplanes are not subject to this proposed AD. We are
currently considering requiring similar actions for these airplanes.
Costs of Compliance
We estimate that this proposed AD will affect 1,987 airplanes of
U.S. registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspection, drive motor assembly 11 work-hours x $252 per $1,187 per $2,358,569 per
brush replacement; and parts $85 per hour = replacement cycle. replacement cycle. replacement cycle
return and reporting. $935 per
replacement cycle.
----------------------------------------------------------------------------------------------------------------
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
[[Page 59148]]
(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
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

This AD was prompted by multiple reports of smoke and/or fire in
the tailcone caused by sparking due to excessive wear of the brushes
in the air conditioning (A/C) motor. We are issuing this AD to
prevent the brushes in the A/C motor from wearing down, which could
result in the rivet in the brush contacting the commutator causing
sparks and consequent fire and/or smoke in the tailcone with no
means to detect or extinguish the fire and/or smoke.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Part Number (P/N) Inspection
Within 30 days or 10 flight hours after the effective date of
this AD, whichever comes first: Inspect the A/C compressor motor to
determine whether P/N 1134104-1 or P/N 1134104-5 is installed. A
review of airplane maintenance records is acceptable in lieu of this
inspection if the part number of the A/C compressor motor can be
conclusively determined from that review.
(h) Inspection of Compressor Hour Meter and Maintenance Records
If during the inspection required by paragraph (g) of this AD,
any A/C compressor motor is found having P/N 1134104-1 or P/N
1134104-5: Within 30 days or 10 flight hours after the effective
date of this AD, whichever occurs first, determine the hour reading
on the A/C compressor hour meter as specified in paragraphs (h)(1)
and (h)(2) of this AD:
(1) Inspect the number of hours on the A/C compressor hour
meter; and
(2) Check the airplane logbook for any entry for replacing the
A/C compressor motor brushes with new brushes, or for replacing the
compressor motor or compressor condenser module assembly (pallet)
with a motor or assembly that has new brushes;
(i) If the logbook contains an entry for replacement of parts as
specified in paragraph (h)(2) of this AD, determine the number of
hours on the A/C compressor motor brushes by comparing the number of
hours on the compressor motor since replacement and use this number
in lieu of the number determined in paragraph (h)(1) of this AD; or
(ii) If through the logbook check you cannot positively
determine the number of hours on the A/C compressor motor brushes as
specified in paragraph (h)(2) of this AD, use the number of hours on
the A/C compressor hour meter determined in paragraph (h)(1) of this
AD or presume the brushes have over 500 hours time-in-service.
(i) Replacement
Using the hour reading on the A/C compressor hour meter
determined in paragraph (h) of this AD, replace the A/C compressor
motor brushes with new brushes at the later of the times specified
in paragraphs (i)(1) and (i)(2) of this AD. Thereafter, repeat the
replacement of the A/C compressor motor brushes at intervals not to
exceed every 500 hours time-in-service on the A/C compressor motor.
Do the replacement in accordance with the applicable Cessna
maintenance manual listed in paragraphs (i)(3)(i) through
(i)(3)(vii) of this AD.
(1) Before or when the A/C compressor motor reaches a total of
500 hours time-in-service; or
(2) Before further flight after the inspection required in
paragraph (h) of this AD.
(3) Replace the A/C compressor motor brushes in accordance with
the instructions in the applicable Cessna maintenance manual
specified in paragraphs (i)(3)(i) through (i)(3)(vii) of this AD.
