[Docket No. FAA-2014-1044; Directorate Identifier 2014-NM-148-AD]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 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.
 DATES: We must receive comments on this proposed AD by March 9, 2015.

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 
                    ( print 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 (*http://rgl.faa.gov/​Regulatory_​and_​Guidance_​Library/​rgstc.nsf/​0/​029C5719AD18E79C86257C1A0069742C?​OpenDocument&​Highlight=​sa3849sw*);
                SA7580SW (*http://rgl.faa.gov/​Regulatory_​and_​Guidance_​Library/​rgstc.nsf/​0/​7C9B0FB7D5923D4986257C1A0069E2C0?​OpenDocument&​Highlight=​sa7580sw*);
                SA7753SW (*http://rgl.faa.gov/​Regulatory_​and_​Guidance_​Library/​rgstc.nsf/​0/​A78233CBB3314BAF86257C1A0069D128?​OpenDocument&​Highlight=​sa7753sw*); or
                SA8918SW (*http://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. Related Service Information We have reviewed the following service information, which describes procedures for replacement of life-limited components including P/N FWA1134104-1 or FWA1134104-5 A/C compressor motor brushes.

                Subject 4-11-00, Replacement Time Limits, of Chapter 4, Airworthiness Limitations, Revision 22, dated June 23, 2014, of the Cessna Model 560 Maintenance Manual.
                Subject 4-11-00, Replacement Time Limits, of Chapter 4, Airworthiness Limitations, Revision 32, dated June 23, 2014, of the Cessna Model 650 Maintenance Manual. 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.

 (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.
