CessnaProceduresManualTextron AviationCessna 500 Series Citation500/501, 550/S550/551, 560THIS GUIDE IS CURRENT WITH THE MASTER MINIMUM EQUIPMENT LIST WHICH IS DISTRIBUTED BY THE DEPARTMENT OF TRANSPORTATION FEDERAL AVIATION ADMINISTRATION - REVISION 10 DATED 01/03/2018.COPYRIGHT ? 2018MMEL REVISION 10Textron AviationWICHITA, KANSAS, U.S.A.CPM REVISION 00NOTICEThe Master Minimum Equipment List (MMEL) is distributed by the Department of Transportation Federal Aviation Administration. This Master Minimum Equipment List Operation and Maintenance Procedures manual contains only the items from the Master Minimum Equipment List which have Maintenance (M) or Operational (O) procedure requirements. Cessna does not support Minimum Equipment List items not published in the MMEL.Cessna’s policy is to revise this manual only to accommodate changes to a new MMEL revision, which requires a change to, or a new, Maintenance (M) or Operational (O) required procedure. If a revised MMEL is released, but does not affect any required procedure, the Operational and Maintenance manual will not be revised at that time. Cessna reserves the right to make format changes without generating a new revision.Maintenance (M) or Operational (O) procedures in this manual are recommended by Cessna Aircraft Company. Most of the procedures in this manual have been approved in some MEL’s. This document is not FAA approved, but is intended to aid operators in writing and gaining approval for their specific Minimum Equipment List (MEL). The Operator is responsible to make sure that all crew members are properly trained in the use of MEL (M) and (O) procedures.The Narrative section of each Maintenance (M) procedure is intended to satisfy the FAR 135 MEL requirement for training non-maintenance individuals who are authorized, in the MEL, to perform maintenance tasks.14 CFR 91 operators must have the following statement included in their COMPs Manual or operator produced Procedures Guide. All other operators must remove or delete the following statement:THIS DOCUMENT IS APPLICABLE TO PART 91 OPERATIONS ONLY AND MAY NOT BE USED FOR OPERATIONS CONDUCTED UNDER PARTS 121, 125, 129, OR 135.NOTESFor all provisos – Unless the proviso requires a system to be verified, it is assumed that all other systems are operative and no action is required to test these systems.Where ever a dash (-) is listed in Column 2: Number Installed or Column 3: Number Required for Dispatch, it is the responsibility of the operator to replace the dash (-) with the actual number of each item, if any, installed on the aircraft in questionThe operator must make an appropriate entry in the discrepancy report for each inoperative item.The diagrams, drawings and/or pictures in this document may not reflect all possible installations. Refer to the aircraft equipment list, continuous history report and/or STC for current installed equipment.The Code of Federal Regulations (CFR), Title 14, Aeronautics and Space, listed in this document may not be up to date with the most current regulation. It is the responsibility of the operators to make sure all applicable 14 CFR parts are listed in their operational documents.The maintenance procedures in this document may be different than those found in the current revision of the Cessna Maintenance Manual for the associated aircraft model. In the event of conflict, use the more restrictive maintenance procedure to accomplish the task.PLACARDING REQUIREMENTSWhen relief is taken for an item listed in a MMEL or operator’s MEL, regulations require the operator to placard the item or system as inoperative or missing. The following guidelines are designed to assist operators with placarding inoperative or missing items or systems. Operators may develop alternate procedures for placarding inoperative or missing items or systems.Placards should be placed above, adjacent to or on the associated / affected control (annunciator, circuit breaker, switch, button, gauge, indicator, knob or light).Pre-manufactured “INOP” or “INOPERATIVE” placards may be used at the discretion of the operator.For missing items or systems, the placard should include text which specifies the component that is missing.If the inoperative item or system is not within view of the flight crew, an additional placard should be placed on the instrument panel in view of the flight crew. The placard should include text which specifies the component that is inoperative.If the relief for an item or system includes limitations on aircraft operations, an additional placard should be placed on the instrument panel in view of the flight crew. The placard should include text which states the limitation. If the limitation contracts a permanent placard installed in the cockpit as a part of the certified aircraft, the placard should be placed adjacent to the permanent placard. For example, a placard restricting VMO should be placed near the MAX OPERATING SPEED placard. Examples of common limitations on aircraft operations are:RVSM OPERATIONS ARE PROHIBITEDOPERATIONS IN IMC ARE PROHIBITEDFLIGHT INTO ICING IS PROHIBITEDOPERATIONS AT NIGHT ARE PROHIBITEDCARRIAGE OF CABIN OCCUPANTS IS PROHIBITEDCARRIAGE OF CARGO (EXCLUDING BALLAST) IS PROHIBITEDSINGLE-PILOT OPERATIONS ARE PROHIBITEDOPERATIONS ABOVE FL410 ARE PROHIBITEDFor indications shown on an electronic display, the placard should be placed adjacent to or on the bezel of the display and should include text which specifies the indication that is inoperative. The placard should NOT be placed on the display as this may obstruct the view of other indications in alternate or reversionary modes. This also applies to specific software functions or items within a system.Placards installed on equipment used by cabin passengers should include text such as “DO NOT USE” if the item or system is deactivated. For example, a vanity basin with an inoperative drain should include a placard stating, “DO NOT POUR LIQUIDS INTO BASIN”. Make sure the placard can be easily understood by all passengers. Consider any passengers whose primary language is not the same as the placard’s language.Items or systems which have external access such as a baggage door or refueling panel should include a placard on the exterior side of the door or on the interior side provided it is prominently in view when accessed. The placard should include text specifying the item or system that is inoperative and / or states limitations on aircraft operations.Placard text should be of appropriate size, font and color so that it can be easily read. Placards placed on the exterior of the aircraft should be made of materials that will not degrade or depart the aircraft, such as aerodynamic tape and permanent marker.Placarding does NOT satisfy the requirement to make an appropriate entry in the discrepancy report for an inoperative or missing item or system.Regulatory ReferencesWhen an item’s proviso includes language such as “any in excess of those required by 14 CFR” or “not required by 14 CFR”, the operator is required to replace this reference with the specific operating requirement applicable to their operation. The following table lists 14 CFR references for certain systems. This table may include references for items not installed on this aircraft or which MMEL relief is not offered. This list is based on Appendix A of FAA MMEL Policy Letter 25.ATAItemTitle14 CFR Reference(s)22-10-XXAutopilot SystemApp G23-00-XXSATCOM135.98, 135.16523-10-XXHigh Frequency (HF) Communication System91.511, 135.98, 135.16523-11-XXUltra High Frequency (UHF) Communication System91.126, 91.127, 91.129, 91.130, 91.131, 91.135, 91.205, 91.511, 135.161, 135.16523-12-XXVery High Frequency (VHF) Communication System91.126, 91.127, 91.129, 91.130, 91.131, 91.135, 91.205, 91.511, 135.161, 135.16523-40-XXPassenger Address (PA) System135.15023-50-XXHeadsets91.511, 135.151, 135.16523-50-XXMicrophone91.511, 135.16523-70-XXCockpit Voice Recorder91.609, 91.1045, 135.15124-30-XXDC Generator135.16325-10-XXPassenger seat shoulder harness91.20525-20-XXUnder seat restraining bars91.52325-20-XXPassenger Briefing Cards91.519, 91.103525-20-XXTables91.53525-20-XXMovie Screens (In aisle)91.53525-20-XXObserver’s Seat135.7525-60-XXEmergency Medical Kit (EMK)25-60-XXFirst Aid Kit (FAK)91.51325-60-XXAutomatic External Defibrillator (AED)25-60-XXPyrotechnic Signaling Device91.205, 91.509, 135.16725-60-XXCrash Axe25-61-XXFlotation Device91.205, 91.509, 135.16725-62-XXEmergency Locator Transmitter (ELT) (Fixed, Automatic)91.20725-62-XXEmergency Locator Transmitter (ELT) (Survival)91.207, 91.509, 135.16725-64-XXLife Raft91.509, 135.16726-22-XXPortable Fire Extinguishers91.513, 135.15530-10-XXAnti-Ice System91.52730-30-XXPitot Heat135.163, App A30-40-XXWindshield WiperApp A31-20-XXClock91.20531-30-XXFlight Data Recorder91.609, 91.1045, 135.15233-20-XXPassenger Information Sign91.51733-40-XXWing Illumination Lights91.52733-40-XXAnti-Collision Light System91.205, 91.209, 135.15933-40-XXLanding Light91.205, 91.50733-40-XXPosition / Navigation Lights91.205, 91.20933-50-XXFlashlight91.503, 135.15934-11-XXStatic Pressure System135.163, App A34-12-XXFree Air Temperature Indicator135.16334-13-XXVertical Speed Indicator135.163, App A34-14-XXAirspeed Indicator91.205, App A,34-15-XXOverspeed Warning91.60334-16-XXAltitude Alerter91.219, App G34-16-XXAltimeter91.20534-16-XXSensitive Altimeter91.205, 135.149, App A34-17-XXAltitude Measurement SystemsApp G34-21-XXGyro Pitch and Bank91.205, 135.159, App A34-22-XXStandby Attitude Indicator135.14934-22-XXMagnetic Direction Indicator91.205, 135.15934-22-XXGyro Direction Indicator91.609, 91.1045, 135.152, 135.15934-24-XXGyro Rate of Turn91.205, 135.15934-24-XXSlip-Skid Indicator91.205, 135.15934-25-XXFlight DirectorApp A34-31-XXInstrument Landing System (ILS)135.165, App A34-34-XXMarker Beacon135.165, App A34-42-XXWeather Radar System91.1045, 135.173, 135.17534-44-XXTerrain Awareness and Warning System91.223, 91.1045, 135.15434-44-XXRadio AltimeterApp A34-45-XXTraffic Alert and Collision Avoidance System (TCAS)91.221, 91.1045, 135.18034-46-XXThunderstorm Detection System91.1045, 135.17334-51-XXDistance Measuring Equipment (DME)91.205, 135.16534-52-XXATC Transponder and Automatic Altitude Reporting System91.130, 91.131, 91.135, 91.215,34-52-XXAutomatic Dependent Surveillance-Broadcast91.130, 91.131, 91.135, 91.225, 34-52-XXElementary and Enhanced Downlink Aircraft Reportable Parameters135.14334-52-XXADS-B Squitter Transmissions91.22734-54-XXVery High Frequency Omnirange (VOR) System91.131, 91.205, 91.511, 135.161, 135.16534-55-XXAutomatic Direction Finder (ADF)91.205, 135.16134-57-XX-60-XXLong-Range Navigation System91.131, 91.205, 91.511, 135.16535-10-XXFlight Crew Oxygen System91.211, 135.15735-20-XXPassenger Oxygen System91.211, 135.15735-30-XXPortable Breathing Equipment (PBE)37-20-XXVacuum Indicator135.16371-60-XXCarburetor Heat135.14977Engine Indications91.205Page Intentionally Left Blank21-00-02-01Precool SystemPressurizedC21(M) One may be inoperative provided:Affected system is deactivated,Pressurization Source Selector remains on the opposite source, andFlight is conducted at FL250 or below.Maintenance ProcedureNOTE:The 500 Series airplane has a specific Maintenance Manual for the respective model(s).
