NOTE : The Airworth i ness Limitatio ns section is FAA Approved and supplies inspection and maintenance requ ired under Parts 43.16 and 91.409 of Part 14 of the Code of Federal Regulations , unless an alternative program has been FAA approved. 

### 2. Definition A. This chapter contains sections as shown below. (1) Inspection Time Limits (4-10-00) describe and g ive a list of the systems and components that must be examined at specified intervals. The intervals given show the maxi mum time approved between the inspections. (2) Replacement Time Limits (4-11-00) give a list ofthe life limited components that must be replaced at a specific time.

### It is recommended that the components be scheduled for replacement during the airplane's inspection interval coinciding with , or occurring just before the expiration of the specified time limit. Procedures for replacement of the components are described in the applicable chapters in this Maintenance Manual. 2. Rep l acement Schedule NOTE : The replacement life limit numbers are for hard surface full stop land ings ; refer to the FAA Approved Airplane Flight Manual for sod/dirt operation. A. A i r Conditioning (Chapter 21 ) (1) Vapor Cycle Cooling System Compressor Drive Motor Brushes (Compressor Motors 1134104-1 , -5 or FWA1134104-1 , -5)- Replace every 500 compressor hours.

Landing Gear (Chapter 32) (1) Brake assembly Good rich P/N 2-1528-6 or 2-1530-4 with stator disks part number 133-893-2 , that are imp ress ion stamped " -" OR "A". -Replace 749 landings (2) Main Gear NOTE: The main gear assemblies cons ist of the following components , wh ich have life limits as listed. The serials l isted for the main gear assemblies and their components are those as the airp lane was originally built. Any component replaced during normal maintenance or by a service bulletin are not reflected in this table. The individual airplane maintenance records must be consulted for part numbers of replacement parts. If it is not possible to verify the part numbers of the individual components currently installed on a specific gear assembly, the like component having the lowest replacement life lim it must be assumed.

## CIL-21-02 Based on availability and lead times , parts may require advanced scheduling. ACCOMPLISHMENT INSTRUCTIONS 1. Prepare the airplane for mai ntenance. A. Make sure that the airplane is electrically grounded. B. Make sure that all switches are in the OFF/NORM position. C. Disconnect electrical power from the airplane . (1) Disconnect the airplane battery. (2) Disconnect external electrical power. D. Attach maintenance warning tags to the battery and external power receptacle that have "DO NOT CONNECT ELECTRICAL POWER - MAINTENANCE IN PROGRESS" written on them. 2. Get access to the air conditioning compressor motor. 3. (Refer to Figure 1.) Identify a location to install the bracket and 1 250703-3 Hour Meter that will provide a minimum of one-inch clearance from all l ines, tubes, wire bundles and equipment. A. Locate the bracket and drill three Number 30 (0 . 128 inch diameter) holes. (1) Deburr the drilled holes. B . Install the bracket with three MS20470AD4 Rivets. (Refer to the Structural Repair Manual, Chapter 51 , Fastener Installation and Removal.) NOTE: The rivet length will vary due to the different installation configurations. Use the correct length rivet with a rivet base code of MS20470AD4. 4. (Refer to Figure 2 .) Install the electrical wiring for the hour meter. NOTE: Use the electrical schematic as a reference to identify the power, control and ground wires for the compressor motor wiring . Your airplane specific wiring can be different, the intent of the electrical schematic is to provide a reference that the hour meter needs an aircraft ground , power and signal connection. 5. Install the hour meter on the bracket. 6 . Remove the maintenance warning tags and connect the airplane battery. 7. Do an operational check of the hour meter by operating the air conditioning for a duration of time sufficient to show that the hour meter is operating correctly. 8. Close access panels and doors that were opened and removed for the modification. 9 . Record that this service letter has been completed. A. Complete a Maintenance Transact ion Report . B. Put a copy of the completed Maintenance Transaction Report in the airplane logbook. C. Send a copy of the completed Maintenance Transaction Report to: CESCOM C/0 Camp Systems International, 8200 East 34th Street North , Building 1600 Suite 1607 Wichita , KS 67226 .

DESC RIPTION This service letter contains information about the vapor cycle air conditioning system compressor motor. COMPLIANCE INFORMATIONAL. This service letter is for informational purposes only. Operators of aircraft equipped with vapor cycle air conditioning systems should be aware of forthcoming maintenance manual revisions, including Chapter 4 limitations , for compressor drive motor brushes. A new mandatory 500-hour brush replacement interval will be mandated for Enviro P/N 1134104-1 and 1134104-5 compressor drive motors , based on compressor pallet hour-meter operation. This is a 300-hour reduction from the orig ina l 800-hour manufacturer-recommended brush replacement interval.

# •• Cessna A Textron Company 

## CIL-21 -01 In addition , Cessna has been notified by the FAA that it is developing an Airworth i ness D i rective ( AD) to enforce the 500-hour brush replacement interval on affected Citations also . With new Chapter 4 revi sions in work, and an impending AD, it is wise for operators to be vigilant in replacing compressor drive motor brushes 

### if they have been operated at or beyond the new 500-hour replacement limit. A motor with worn brushes not in compliance could potentially affect the continued airworthiness of an aircraft. Chapter 5 will include a requ irement to do an inspection and log hour meter read i ngs for the vapor cycle air conditioning system.
