Federal Register Abstract
We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company Model 500, 501, 550, 551, S550, 560, and 650 airplanes. 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. This AD requires 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 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.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Cessna Aircraft Company Model 500, 501, 550, 551, S550, 560, and 650
airplanes. 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. This AD requires 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
[[Page 51444]]
placard installation; and return of replaced brushes to Cessna. 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.
DATES: This AD is effective September 29, 2015.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of September 29,
2015.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain Cessna Aircraft
Company Model 500, 501, 550, 551, S550, 560, and 650 airplanes. The
NPRM published in the Federal Register on January 23, 2015 (80 FR
3516). The NPRM was prompted by reports of smoke and/or fire in the
tailcone caused by sparking due to excessive wear of the brushes in the
A/C motor. The NPRM proposed to 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 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.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (80 FR 3516, January 23,
2015) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting this AD as proposed except for
minor editorial changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM (80 FR 3516, January 23, 2015) for correcting the unsafe
condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (80 FR 3516, January 23, 2015).
Interim Action
We consider this AD interim action. The reporting data required by
this 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.
Related Service Information Under 1 CFR Part 51
We reviewed the following service information, which describes
procedures for replacement of life-limited components, including part
number FWA1134104-1 or FWA1134104-5 A/C compressor motor brushes.

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
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.

(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 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.

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
