Airworthiness Directives; Cessna Aircraft Company Airplanes

Publication 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.

14 CFR Part 39

[Docket No. FAA-2012-1001; Directorate Identifier 2012-NM-020-AD; 
Amendment 39-17453; AD 2013-09-11]
RIN 2120-AA64


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:
    <bullet> Are consistent with the intent that was proposed in the 
SNPRM (78 FR 9636, February 11, 2013) for correcting the unsafe 
condition; and
    <bullet> 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:

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.

(ATA) of America Code 21, Air Conditioning.

(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.
    (2) Before further flight after doing the inspection required in 
paragraph (h) of this AD.

(j) Replacement Maintenance Manual Information

    Use the instructions in the applicable Cessna maintenance manual 
subject specified in paragraphs (j)(1) through (j)(7) of this AD to
