Maintenance he design mitations(AWL’s),Certification Maintenance Requirements(CMR’s), Maintenance Significant Items,(MSI) and Structurally Signification Items(SSI).This information may be utilised in themaintenance7
Maintenance Programs – MRB Aims To ensure realization of the inherent safetyand reliability levels of the aircraftTo restore safety and reliability to theirinherent levels when deterioration has occurredTo obtain the information necessary fordesign improvement of those items whoseinherent reliability proves inadequateTo accomplish these goals at a minimum totalcost, including maintenance costs and thecosts of resultant failures8
Maintenance Programs - MRBMaintenance Review Board (MRB) is aregulatory body TheInternational MaintenanceReview Board Policy Board (IMRBPB)is a chartered organization of regulatoryauthoritiesthat recognizes the ATAMSG 3 process as an acceptable standard The MRB process is intended to be acollaborative one involving airlineoperators, manufacturersandregulatory authorities 9
Maintenance Programs - MRB The scheduled maintenance development process,comprises representatives of the operators, themanufacturers of the airframe and engine, and the regulatingauthoritiesManagement of the development activities isaccomplished by anIndustry Steering Committee (ISC) Maintenance Working Groups (MWG) will be establisheddepending on the complexity of the aircraft, I.e. systems,powerplant, zonal and structures The developed maintenance activities will be submitted forapproval, to the Maintenance Review Board (MRB)10
Maintenance Programs - MRB The working procedures aredetailed in a Policy and ProceduresHandbook (PPH). The Maintenance Review Board (MRB)reviews the maintenance proposalssubmitted by Industry Steering Committee(ISC) Once accepted by ISC the maintenanceproposal becomes the MRB ReportProposal (MRBR(P))11
Maintenance Programs - MRBMSG-3 Analysis ProcedureAfter the MSI’s have been selected the followingmust beidentified for each MSI:Functions(s) – the normal characteristic actions ofthe item.b) Functional Failure(s) – Failure of an item to performits intended function within specified limits.c)Failure Effect(s) – what is the effect of a functionalfailured)Failure Causes(s) – why the functional failureoccursa)12

Maintenance Programs - MRBFailure Effect Categories FEC (First Level)Once the analysts have answered theapplicable first level questions, they aredirected to one of the five Effect Categories; Evident Safety (Category 5)Evident Operational (Category 6)Evident Economic (Category 7)Hidden Safety (Category 8)Hidden Non-Safety (category 9)21
Maintenance Programs - MRBZonal Program – Zonal inspections are the general visualinspections. They are intended to detect deterioration of theoriginal installations within the defined zones.Such as:corrosion, cracks and evidence of fluid leaks/overheat/ductdamage, security and condition of wiring. Security andcondition of components.22
Maintenance Programs MRBOn completion of the MRB process theMRBR is signed off by the appropriateregulatory authority From the MRBR, the aircraft manufacturerwill produce a MaintenancePlanning Document (MPD)for use by the operator ofthe aircraft 23

Approval of the Maintenance Program The authority designated The competent authorityby the Member State of registry shall verify thatmaintenance Programs in compliance with M.A.302 Indirect approval when the aircraft is managed byan M.A. Subpart G organization the MPand its amendments may be approved byprocedure established by theorganisation (M.A.302)27
Approval of the Maintenance ProgramAn aircraft can only be maintained to oneApprovedMaintenance Program To move an aircraft from one Program toanother will involve submitting anamendment to the CAA for approvalA review of the differences between thePrograms carried out this may result in theneed for a 'Bridging Check' to cater for anydifferences28

Approval of the Maintenance ProgramMaintenance Programs should be developed from TypeCertificate Holder / Supplemental Type Certificate Holder(TCH / STCH) information. Maintenance Program Checklist – Form SRG1724 The purpose of the maintenance Program check list if toassist owners and operators in the submission with a view toensuring that the Maintenance Programs submitted to theCAA are standardized and include all items that are requiredby Part M.A.302, AMC M.A.302 and also any other additionalCAA nationally required items. Available on CAA Website 30
Approval of the Maintenance ProgramThe approval verification should consider thefollowing items: Program rules System / powerplant rules & requirements Structural Program & associated rules &requirements Zonal Program & associated rules &requirements All tasks are identified by their MSI / SSI STC/Modifications inspection requirements31
Approval of the Maintenance Program FEC and CMR’s positively identified Airworthiness LimitationsThe usage parameters with a FEC of 5 & 8 or whichareCMR should be carefully considered Buyer Furnished Equipment (BFE) Ageing Aircraft Repeat Inspection of Repairs Maintenance Program Tasks traceability to source document(MPD, MRBR, MM Chapter 5, OperatorsRequirements)32
Aircraft MTWA 2730kgs Light Aircraft Maintenance Schedule –Aeroplanes/Helicopters (LAMS) published andapproved by CAAGeneric schedule applicable to piston enginedaircraft 2730kg (non EASA) Light Aircraft Maintenance Program– Aeroplanes/ Helicopters (LAMP) published andapproved by CAAGeneric schedule applicable to piston-enginedaircraft 2730kg Part M, M.A.302 Compliant whencustomized 33
Aircraft MTWA 2730kgsLAMS/LAMP are generic and therefore it isimportant that:The Owner/Operator completes the introductorydetails The Program is customized for AirworthinessLifeLimitations, Overhaul and Test Periods The Program is customized for AdditionalInspections CAP 543 or equivalent is used34
Effectiveness of the Maintenance Program The operator is required to continue to monitorthe effectiveness of the maintenanceProgram (EASA Part M.A. 302 (a))The operator may elect to ‘Contract’ continuingairworthiness tasks to another appropriatelyapproved organization (EASA Part M SubpartG) The process required to monitor theeffectiveness is dependent upon methodologyapplied by TC holder35
Effectiveness of the Maintenance Program Reliability Programs are designed to supplement theoperatorsProgram for maintaining aircraft ina continuous state of airworthiness (ICAO)Reliability Programs should be developed for aircraftmaintenance Programs based upon maintenancesteering group (MSG) logic or those that includecondition monitored components or that do notcontain overhaul time periods for all significantsystem components (EASA) Reliability Programs need not be developed foraircraft not considered as large aircraft or that containoverhaul time periods for all significant aircraft systemcomponents36
Effectiveness of the Maintenance Program The purpose of a reliability Program is toensure that the aircraft maintenance Programtasks are effective and their periodicity isadequateThe reliability Program may result in theescalation or deletion of a maintenance tasks,as well as the de- escalation or addition of amaintenance task A reliability Program provides an appropriatemeans of monitoring the effectiveness of themaintenance Program37
Effectiveness of the MaintenanceProgramThe reliability Program procedure may includemonitoring of: Pilots Reports, Technical Logs Aircraft Maintenance Access Terminal / On-boardMaintenance System readouts Maintenance Worksheets Component Removals and Workshop Reports Reports on Functional Checks AND Special Inspections Stores Issues/Reports Air Safety Reports Reports on Technical Delays and Incidents Other sources (ETOPS, RVSM, CAT II/III)38
Optimization of the Maintenance ProgramThe optimisation process should be set outin the operator or maintenanceorganisation CAME / MOE / MaintenanceProgram / Manuals.Where large transport aircraft Programsare developed using MSG methodology,the operator optimisation process shouldinclude methodology which itself is basedupon MSG processes or similar.39
Optimization of the Maintenance ProgramAnything can be escalated if appropriatelyjustified!Some things require more justification than others: CMR and any Airworthiness Limitations aretype certification issues, and can only be variedwith the TC holders supportAD’s intervals can only be escalated with thespecific approval of the NAAProceed with extreme caution for items suchas CMR, FEC 5 & 8, SSI40
Optimization of the MaintenanceProgramA Maintenance Program approvedfor one Operator and onemaintenance organisation does notmean automatic approval at another.A Maintenance Program is unique tothe operational environment, utilisation,modification status, maintenance andinspection standards applied.41
Optimisation of the Maintenance ProgramOptimisation could result in the following changes totheApproved Maintenance Program; Change to compliance interval category (FH,FC, Calendar, Check etc) Escalation or reduction of compliance interval Revision of task/process (insp, CK, FC, OPC etc) Revision of accomplishment instructions Deletion of Task or Process Revision of work scope Addition of tasks42
Optimization of the Maintenance Program Changes to a scheduled Maintenance Program should bemade in an incremental and controlled manner wherepossible, by Trial Extension or sampling Programs‘Sample’ size and review period (gates) to be agreed withNAA (Typically 10% - 15% of fleet) Type Certificate Holders support Increment to be agreed with NAA ‘Rate of Change’ may be high for a new type recentlyintroduced to service more conservative for old types orinexperienced operator / maintenance organizations43
Optimization of the Maintenance ProgramJustification could include audit of; Maintenance Standards (line and base)Data CollectionData ProcessingDeferred / Carry Forward DefectsAircraft Utilisation‘NIL Defects’ is not in itself, justification forescalation or deletion44
Optimization of the Maintenance ProgramPireps and ‘Technical Delay’ summaries alone, do notprovide justification for escalation/task deletion.Additional data from the reliability Program should beincluded;Component Strip ReportsComponent Reliability DataOccurrence and Safety Report RatesWorkpack Non Routine Card RatesTest/Flight Test Report Findings‘Safety’ (e.g. FEC 5/8) Defect Rates ‘Global’ Data - Where Obtainable from TC Holder 45
Maintenance Programs SummarySummary: TC Holder recommendations should form the basis of theoperators maintenance ProgramThe Operator is responsible for monitoring effectiveness ofthe maintenance Program and the process should be auditedThe maintenance Program process brings togethermaintenance and designThe maintenance compliance and inspection standards playa significant role in an effective Maintenance Program andshould be audited The competent authority shall verify that the maintenanceProgram is in compliance46
