Airworthiness Directives; Cessna
Aircraft Company Airplanes
Federal Aviation
Administration (FAA), DOT.
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, and 650
airplanes. This proposed AD was
prompted by 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 inspections
to determine if certain A/C compressor
motors are installed and to determine
the accumulated hours on certain A/C
compressor motor assemblies; and
repetitive replacement of the brushes in
the A/C compressor motor assembly, or,
as an option to the brush replacement,
deactivation of the A/C system and
placard installation; 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.
SUMMARY:
We must receive comments on
this proposed AD by March 9, 2015.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following
methods:
• Federal eRulemaking Portal: Go to

Discussion
We have received 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
E:\FR\FM\23JAP1.SGM
23JAP1
Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules
beyond their limits on the part number
(P/N) 1134104–1 A/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,
and 650 airplanes. Therefore, those
Model 500, 501, 551, S550, and 650
airplanes might be subject to the unsafe
condition revealed on Model 525, 550,
and 560 airplanes.

Related ADs
AD 2013–09–11, Amendment 39–
17453 (78 FR 32349, May 30, 2013), was
issued for certain Cessna Aircraft
Company Model 500, 501, 550, 551,
S550, 560, 560XL, and 650 airplanes.
AD 2013–09–11 requires inspecting to
determine if certain A/C compressor
motors are installed and to determine
the accumulated hours on certain A/C
compressor motor assemblies; and
repetitive replacement of the brushes in
the A/C compressor motor assembly, or,
as an option to the brush replacement,
deactivation of the A/C system and
placard installation; and return of
replaced brushes to Cessna.
After AD 2013–09–11, Amendment
39–17453 (78 FR 32349, May 30, 2013),
was published the FAA received several
questions asking if AD 2013–09–11 is
applicable to airplanes having an air
conditioning system installed via any of
the following Fort Worth Airworks
supplemental type certificates (STCs):
• SA3849SW (https://rgl.faa.gov/

&Highlight=sa8918sw).
The A/C compressor motor part
numbers installed via these STCs are the
same as in AD 2013–09–11, except the
prefix ‘‘FWA’’ has been added to the
part numbers of the A/C compressor
motor installed via the STCs
(FWA1134104–1 or FWA1134104–5).
Based on a discussion between the
FAA and Cessna, we determined that
AD 2013–09–11, Amendment 39–17453
(78 FR 32349, May 30, 2013), should
also apply to A/C compressor motor
airplanes with P/N FWA1134104–1 or
P/N FWA1134104–5 installed. Instead
of superseding AD 2013–09–11 to add
these airplanes to the applicability, the
FAA is issuing this new proposed AD
applicable only to airplanes with P/N
FWA1134104–1 or P/N FWA1134104–5
installed.
Cessna Model 560XL airplanes are not
included in the applicability of this
proposed AD because the Fort Worth
Airworks STCs identified previously are
not installed on that airplane model.
AD 2013–08–05, Amendment 39–
17422 (78 FR 24343, April 25, 2013),
addresses the same unsafe condition
that prompted this proposed AD. AD
2013–08–05 is applicable to Cessna
Aircraft Company Model 525 airplanes.
The Fort Worth Airworks STCs
referenced above do not apply to the
Cessna Model 525 airplanes; therefore,
this proposed AD does not affect AD
2013–08–05.
After AD 2013–08–05, Amendment
39–17422 (78 FR 24343, April 25, 2013);
and AD 2013–09–11, Amendment 39–
17453 (78 FR 32349, May 30, 2013);
were published, the FAA determined
that there are some airplanes on which
the air conditioning motor system had
been installed via the Fort Worth
Airworks STCs mentioned previously,
and an A/C compressor hour meter was
not part of the type design. To assist in
future compliance with this proposed
AD, an A/C compressor hour meter may
be installed. The installation can be
done using Cessna Service Letter CIL–
21–02, dated January 23, 2014, or by a
method approved by the FAA.

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 these same
type designs.
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 for certain A/C compressor
motors to determine the number of
hours accumulated on the motors; and
repetitive replacement of the brushes in
the A/C compressor motor assembly, or
optional deactivation of the A/C system
and installation of a placard prohibiting
use of the A/C system until replacement
of the brushes. This proposed AD would
also require, when the brushes are
replaced, reporting 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.
Costs of Compliance
We estimate that this proposed AD
affects 333 airplanes of U.S. registry.

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

Parts cost
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.
§ 39.13
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
(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.

(e) Unsafe Condition
This AD was prompted by 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 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.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
(g) Inspection for Part Number (P/N)
Within 30 days or 10 flight hours after the
effective date of this AD, whichever occurs
first: Inspect the A/C compressor motor to
determine whether P/N FWA1134104–1 or P/
N FWA1134104–5 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.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Cessna Aircraft Company Model 500, 501, 550, 551, S550, 560,
and 650 airplanes. This proposed AD was prompted by 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 inspections to determine if certain A/C compressor motors are
installed and to determine the accumulated hours on certain A/C
compressor motor assemblies; and repetitive replacement of the brushes
in the A/C compressor motor assembly, or, as an option to the brush
replacement, deactivation of the A/C system and placard installation;
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.

receive about this proposed AD.
Discussion
We have received 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
[[Page 3517]]
beyond their limits on the part number (P/N) 1134104-1 A/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, and 650 airplanes.
Therefore, those Model 500, 501, 551, S550, and 650 airplanes might be
subject to the unsafe condition revealed on Model 525, 550, and 560
airplanes.
Related ADs
AD 2013-09-11, Amendment 39-17453 (78 FR 32349, May 30, 2013), was
issued for certain Cessna Aircraft Company Model 500, 501, 550, 551,
S550, 560, 560XL, and 650 airplanes. AD 2013-09-11 requires inspecting
to determine if certain A/C compressor motors are installed and to
determine the accumulated hours on certain A/C compressor motor
assemblies; and repetitive replacement of the brushes in the A/C
compressor motor assembly, or, as an option to the brush replacement,
deactivation of the A/C system and placard installation; and return of
replaced brushes to Cessna.
After AD 2013-09-11, Amendment 39-17453 (78 FR 32349, May 30,
2013), was published the FAA received several questions asking if AD
2013-09-11 is applicable to airplanes having an air conditioning system
installed via any of the following Fort Worth Airworks supplemental
type certificates (STCs):
SA3849SW (https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/029C5719AD18E79C86257C1A0069742C?OpenDocument&Highlight=sa3849sw);
SA7580SW (https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/7C9B0FB7D5923D4986257C1A0069E2C0?OpenDocument&Highlight=sa7580sw);
SA7753SW (https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/A78233CBB3314BAF86257C1A0069D128?OpenDocument&Highlight=sa7753sw); or
SA8918SW (https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/5FAD7ABA3EAA464C86257C1A0069F239?OpenDocument&Highlight=sa8918sw).
The A/C compressor motor part numbers installed via these STCs are
the same as in AD 2013-09-11, except the prefix ``FWA'' has been added
to the part numbers of the A/C compressor motor installed via the STCs
(FWA1134104-1 or FWA1134104-5).
Based on a discussion between the FAA and Cessna, we determined
that AD 2013-09-11, Amendment 39-17453 (78 FR 32349, May 30, 2013),
should also apply to A/C compressor motor airplanes with P/N
FWA1134104-1 or P/N FWA1134104-5 installed. Instead of superseding AD
2013-09-11 to add these airplanes to the applicability, the FAA is
issuing this new proposed AD applicable only to airplanes with P/N
FWA1134104-1 or P/N FWA1134104-5 installed.
Cessna Model 560XL airplanes are not included in the applicability
of this proposed AD because the Fort Worth Airworks STCs identified
previously are not installed on that airplane model.
AD 2013-08-05, Amendment 39-17422 (78 FR 24343, April 25, 2013),
addresses the same unsafe condition that prompted this proposed AD. AD
2013-08-05 is applicable to Cessna Aircraft Company Model 525
airplanes. The Fort Worth Airworks STCs referenced above do not apply
to the Cessna Model 525 airplanes; therefore, this proposed AD does not
affect AD 2013-08-05.
After AD 2013-08-05, Amendment 39-17422 (78 FR 24343, April 25,
2013); and AD 2013-09-11, Amendment 39-17453 (78 FR 32349, May 30,
2013); were published, the FAA determined that there are some airplanes
on which the air conditioning motor system had been installed via the
Fort Worth Airworks STCs mentioned previously, and an A/C compressor
hour meter was not part of the type design. To assist in future
compliance with this proposed AD, an A/C compressor hour meter may be
installed. The installation can be done using Cessna Service Letter
CIL-21-02, dated January 23, 2014, or by a method approved by the FAA.

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 these same type
designs.
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 for certain A/C compressor motors to determine
the number of hours accumulated on the motors; and repetitive
replacement of the brushes in the A/C compressor motor assembly, or
optional deactivation of the A/C system and installation of a placard
prohibiting use of the A/C system until replacement of the brushes.
This proposed AD would also require, when the brushes are replaced,
reporting 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.
Costs of Compliance
We estimate that this proposed AD affects 333 airplanes of U.S.
registry.

Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information
Collection Clearance Officer, AES-200.
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
(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

------------------------------------------------------------------------
(d) Subject
Air Transport Association (ATA) of America 21, Air Conditioning.
(e) Unsafe Condition
This AD was prompted by 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 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.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Inspection for Part Number (P/N)
Within 30 days or 10 flight hours after the effective date of
this AD, whichever occurs first: Inspect the A/C compressor motor to
determine whether P/N FWA1134104-1 or P/N FWA1134104-5 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 having P/N FWA1134104-1 or P/N FWA1134104-5
is found: 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 accumulated on the A/C
compressor hour meter.
(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 accumulated 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.
(ii) If, through the logbook check, a determination cannot be
made regarding the number of hours accumulated on the A/C compressor
motor brushes, as specified in paragraph (h)(2) of this AD, use the
number of hours accumulated 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 500 hours' time-in-service on the A/C compressor motor. Do
the replacement in accordance with the applicable Cessna maintenance
manual subject specified in paragraphs (j)(1) through (j)(6) of this
AD.
(1) Before the accumulation of 500 total hours' time-in-service
on the A/C compressor motor.
(2) Before further flight after doing the inspection required in
paragraph (h) of this AD.
(j) Maintenance Manual Information for Replacement
Use the instructions in the applicable Cessna maintenance manual
subject specified in paragraphs (j)(1) through (j)(6) of this AD to
do the replacement required by paragraph (i) of this AD.
