MAINTENANCE MANUAL 

AIRWORTHINESS LIMITATIONS 

A. This chapter gives the mandatory replacement times and inspection intervals for life limited 

components and airplane structures, or those that require scheduled inspections. This chapter is 

related to items such as fatigue components and structures, which are though of as a part of the 

certification process. 

NOTE: The Airworthiness Limitations section is FAA Approved and supplies inspection and 

maintenance required 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 give a list of the systems and components that 

must be examined at specified intervals. The intervals given show the maximum time approved 

between the inspections. 

(2) Replacement Time Limits (4-11-00) give a list of the life limited components that must be replaced 

at a specific time.

INSPECTION TIME LIMITS 

1. General 

2. 

A. The inspection time intervals applying to the following systems and components represent the 

maximum inspection intervals which must be adhered to. Detailed inspection and maintenance 

check procedures related to the items listed below are outlined in the referenced Inspection Task. 

Inspection Schedule 

A. Air Conditioning (Chapter 21) 

(1) Vapor Cycle Cooling System Hourmeter Check (Compressor Motors 1134104-1, -5 or 

FWA1134104-1 , -5)- Examine every 300 hours. Refer to Task 21-51-01-212. 

NOTE: Refer to the GM R134A Enviro Systems Inc. General Operating, Servicing, and 

Maintenance Manual. 

B. Landing Gear (Chapter 32) 

(1) Brake assembly Goodrich P/N 2-1528-6 or 2-1530-4 with stator disks part number 133-893-2, 

that are impression stamped "-" OR "A". 

(a) Airplanes not equipped with thrust reversers or not using thrust reversers - Inspect by 

224 landings and every 200 landings thereafter until replacement life is reached. (749 

landings). Task 32-40-00-211 

(b) Airplanes with and using thrust reversers - Inspect at 425 landings and replace at 

replacement life (749 landings). Task 32-40-00-211 

(2) Nose Landing Gear Fork (Part Number 5542300-1, -3) - Inspect 12,000 landings and every 1000 

landings thereafter. Task 32-20-00-250 

NOTE: These components also have replacement time limits. Refer to Chapter 4-11-00, 

Replacement Time Limits, for replacement criteria. 

(3) Left Main Landing Gear Side Brace Fitting (Part Number 5522720-1 , -7, -15, -17, -21 , -25)-

Inspect every 5000 landings. Task 57-40-00-250 

(4) Right Main Landing Gear Side Brace Fitting (Part Number 5522720-2, -8, -14, -16, -22, -26) -

MAINTENANCE MANUAL 

REPLACEMENT TIME LIMITS 

A. The following life limited components are to be replaced at the specified 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. Replacement Schedule 

NOTE: The replacement life limit numbers are for hard surface full stop landings; refer to the FAA 

Approved Airplane Flight Manual for sod/dirt operation. 

A. Air 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. 

NOTE: Refer to the GM R134A Enviro Systems Inc. General Operating, Servicing, and 

Maintenance Manual. 

B. Landing Gear (Chapter 32) 

(1) Brake assembly Goodrich P/N 2-1528-6 or 2-1530-4 with stator disks part number 133-893-2, 

that are impression stamped "-" OR "A". -Replace 749 landings 

(2) Main Gear 

NOTE: The main gear assemblies consist of the following components, which have life limits 

as listed. The serials listed for the main gear assemblies and their components are 

those as the airplane 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 limit must be assumed.

Some Air Conditioning (AC) systems do not have an hour meter for the compressor motor. An hour meter 

will provide a more accurate record of motor operation time. 

DESCRIPTION 

This service letter provides parts and general instructions to install a bracket and hour meter for the 

AC compressor motor. 

NOTE: Due to the different AC Systems installed by Supplemental Type Certificate (STC), this service 

letter provides only part numbers and general instructions. It is the owner/operators responsibility 

to establish approval for the installation with the FAA Form 337, Major Repair and Alteration.

ACCOMPLISHMENT INSTRUCTIONS 

1. Prepare the airplane for maintenance. 

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 1250703-3 Hour Meter that will provide a 

minimum of one-inch clearance from all lines, 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 Transaction 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.

REASON 

To inform operators of an upcoming maintenance manual changes for inspection and replacement of the 

vapor cycle compressor motor brushes. 

DESCRIPTION 

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 original 800-hour manufacturer-recommended brush replacement interval.

In addition, Cessna has been notified by the FAA that it is developing an Airworthiness Directive (AD) to enforce 

the 500-hour brush replacement interval on affected Citations also. With new Chapter 4 revisions 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 requirement to do an inspection and log hour meter readings for the vapor cycle air conditioning system.
