Airworthiness Directives; Cessna Aircraft Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of
comment period.
-----------------------------------------------------------------------
SUMMARY: We are revising an earlier proposed airworthiness directive
(AD) for certain Cessna Aircraft Company Model 500, 501, 550, 551,
S550, 560, 560XL, and 650 airplanes. That NPRM proposed to require an
inspection to determine if certain air conditioning (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. That NPRM 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 A/C motor. This action revises
that NPRM by revising the optional A/C system deactivation procedure.
We are proposing this supplemental NPRM 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. Since these actions impose an
additional burden over that proposed in the NPRM, we are reopening the
comment period to allow the public the chance to comment on these
proposed changes.
DATES: We must receive comments on this supplemental NPRM by March 28,
2013.

Discussion
We issued an NPRM to amend 14 CFR part 39 to include an AD that
would apply to the products listed above. That NPRM published in the
Federal Register on September 26, 2012 (77 FR 59146). That NPRM
proposed to 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.
Actions Since Previous NPRM (77 FR 59146, September 26, 2012) Was
Issued
Since we issued the previous NPRM (77 FR 59146, September 26,
2012), Cessna has revised the A/C system deactivation procedure.
Comments
We gave the public the opportunity to comment on the previous NPRM
(77 FR 59146, September 26, 2012). The following presents the comments
received on the NPRM and the FAA's response to each comment.
Request To Change A/C System Deactivation Procedure
Cessna requested that we change the A/C system deactivation
procedure specified in paragraph (j)(1) of the previous NPRM (77 FR
59146, September 26, 2012), because simply pulling the circuit breaker
does not disable the A/C compressor motor for Model 560XL airplanes,
and the circuit breaker labeling differs depending on the airplane
model. Cessna stated that the vapor cycle A/C circuit breaker labeled
``AIR COND'' for Model 500, 501, 550, 551, S550, and 560 airplanes
should be pulled, and the vapor cycle A/C circuit breaker labeled ``FWD
EVAP FAN'' for Model 650 airplanes should be pulled. Cessna also stated
that, for Model 560XL airplanes, deactivation of the A/C system
requires removing a
[[Page 9637]]
certain fuse limiter. Cessna suggested a procedure to remove that fuse
limiter.
We agree with the commenter's request because the new procedure is
more appropriate to address the identified unsafe condition. We have
changed paragraph (k) of the supplemental NPRM (i.e., paragraph (j) of
the previous NPRM) to specify the correct A/C system deactivation
procedure. We have also added new paragraph (l) to this supplemental
NPRM, which specifies the optional reactivation procedure for the A/C
system, and re-identified subsequent paragraphs accordingly.
Request To Extend Compliance Time
Netjets Aviation Inc. (Netjets) requested that we extend the
inspection compliance time in paragraph (h) of the NPRM (77 FR 59146,
September 26, 2012) from within 30 days or 10 flight hours, whichever
occurs first, to within 90 days or 60 flight hours, whichever occurs
first. Netjets stated that it operates 29 airplanes affected by the
NPRM, which average 62 flight hours per month per airplane, and the
compliance time in the NPRM poses an undue burden. Netjets also stated
that extending the proposed compliance time would allow time to
schedule maintenance personnel and material to support each airplane
without compromising safety.
We do not agree with the commenter's request to extend the
compliance time. In developing an appropriate compliance time for this
action, we considered the urgency and severity associated with the
identified unsafe condition. In light of these considerations, we find
the proposed compliance time to be appropriate to address the
identified unsafe condition and provide an adequate level of safety.
However, under the provisions of paragraph (q) of this supplemental
NPRM, we might consider requests for approval of an extension of the
compliance time if sufficient data are submitted to substantiate that
the new compliance time would provide an acceptable level of safety. We
have not changed this supplemental NPRM in this regard.
Request To Change A/C Compressor Motor Brush Replacement Time
Netjets requested we specify that the repetitive 500 hours time-in-
service A/C compressor motor brush replacement may be done ``in a
scheduled inspection based on the Cessna 560 chapter 5 inspection
programs.'' Netjets stated that this change would allow a more robust
and systematic approach to scheduling brush replacement.
We disagree with the commenter's request to change the repetitive
500 hours time-in-service A/C compressor motor brush replacement time.
The 500 hours time-in-service replacement period is based on data
collected from the field. This supplemental NPRM would require
reporting for the first two replacement cycles. The intent of this
proposed requirement is to obtain further field data to determine if
the replacement period might be extended through future rulemaking.
However, under the provisions of paragraph (q) of the supplemental
NPRM, we might consider requests for changing the repetitive 500 hours
time-in-service A/C compressor motor brush replacement period if
sufficient data are submitted to substantiate that the change would
provide an acceptable level of safety. We have not changed the
supplemental NPRM in this regard.
Request To Use Later Revisions of Service Documents
Cessna requested that we change the document revision references in
paragraph (i)(3) of the previous NPRM (77 FR 59146, September 26, 2012)
to refer to the specified revision level ``or later revisions.'' Cessna
stated that referencing only a specific revision level will cause
confusion for maintenance personnel when the manuals are updated with a
newer revision and date. Cessna also stated that its customer support
receives calls from maintenance personnel requesting old revisions of a
manual due to ADs requiring an exact revision and that old revisions
are not available.
We acknowledge this concern, but cannot agree with the commenter's
request to include unspecified later document revisions. When referring
to a specific document in an AD, using the phrase, ``or later FAA-
approved revisions,'' violates Office of the Federal Register
regulations for approving materials that are incorporated by reference.
However, affected operators may request approval to use a later
revision of the referenced service document as an alternative method of
compliance under the provisions of paragraph (q) of the supplemental
NPRM. We have not changed the supplemental NPRM in this regard.
Request To Investigate Other A/C Motor Assemblies
An anonymous commenter requested that we investigate other A/C
drive motor assemblies, because these motors are quite difficult to get
to and are often overlooked. The commenter also stated that there are
other supplemental type certificates (STCs) for the Cessna Citation
that use a similar motor to the motor identified in the previous NPRM
(77 FR 59146, September 26, 2012).
We infer that the commenter wants us to investigate if there are
other unsafe conditions occurring in other A/C motor assemblies used in
the airplanes identified in this supplemental NPRM. We acknowledge the
commenter's concern. We only have event reports pertaining to the A/C
motors addressed by this supplemental NPRM. If an additional unsafe
condition is determined to exist on other A/C motors, we might consider
future rulemaking. We have not changed this supplemental NPRM in this
regard.
Request To Clarify ``Proposed AD Requirements''
Cessna requested that we clarify the statement in the ``Proposed AD
Requirements'' paragraph of the previous NPRM (77 FR 59146, September
26, 2012) regarding motor brush replacement. Cessna suggested that the
wording be changed from ``prohibiting use of the A/C system until
replacement of the brushes as an option to the brush replacement'' to
``prohibiting use of the A/C system until replacement of the brushes is
accomplished.''
We agree with the commenter's request because the suggested wording
improves the clarity of the proposed actions. We have changed the
``Proposed Requirements of the Supplemental NPRM'' paragraph of this
supplemental NPRM accordingly.
FAA's Determination
We are proposing this supplemental NPRM 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. Certain changes described above expand the scope of the
original NPRM (77 FR 59146, September 26, 2012). As a result, we have
determined that it is necessary to reopen the comment period to provide
additional opportunity for the public to comment on this supplemental
NPRM.
Proposed Requirements of the Supplemental NPRM
This supplemental NPRM 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 part number (P/N) 1134104-1 or P/N
1134104-5 A/C compressor motors installed; repetitive replacement of
the brushes, or as an option to the brush replacement, deactivation of
the A/C
[[Page 9638]]
system with installation of a placard prohibiting use of the A/C system
until replacement of the brushes is accomplished. This supplemental AD
would also require, when the brushes are replaced, reporting of
airplane information related to the replacement of the brushes, and
sending the replaced motor brushes to the Cessna Aircraft Company for
two replacement cycles.
Interim Action
We consider this supplemental NPRM interim action. The reporting
data required by this supplemental NPRM 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 supplemental NPRM. 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:

----------------------------------------------------------------------------------------------------------------
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.

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
[[Page 9639]]
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
do the replacement required by paragraph (i) of this AD.
