[Docket No. FAA-2012-1001; Directorate Identifier 2012-NM-020-AD;
Amendment 39-17453; AD 2013-09-11]

Airworthiness Directives; Cessna Aircraft Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Cessna Aircraft Company Model 500, 501, 550, 551, S550, 560, 560XL, and
650 airplanes. 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. This AD requires
inspecting to determine if certain A/C compressor motors are installed
and 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 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.
DATES: This AD is effective July 5, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of July 5, 2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (SNPRM) to
amend 14 CFR part 39 to include an airworthiness directive (AD) that
would apply to the specified products. That SNPRM published in the
Federal Register on February 11, 2013 (78 FR 9636). The original NPRM
(77 FR 59146, September 26, 2012) proposed to require an inspection to
determine if certain A/C compressor motors are installed and 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 A/C system
and placard installation; and return of replaced brushes to Cessna. The
SNPRM proposed to revise the optional A/C system deactivation
procedure.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the SNPRM (78 FR 9636, February 11,
2013) 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 the AD as proposed--except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
SNPRM (78 FR 9636, February 11, 2013) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the SNPRM (78 FR 9636, February 11, 2013).
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.
Model 525 airplanes are not subject to this AD. We are currently
considering requiring similar actions for these airplanes.
Costs of Compliance
We estimate that this AD will affect 1,987 airplanes of U.S.
registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.

airplanes (370 airplanes).
----------------------------------------------------------------------------------------------------------------
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 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) 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 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 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)(7) of this
AD.
(1) Before the accumulation of 500 total hours time-in-service
on the A/C compressor motor.
