Chapter 7 Maintenance and Engineering Organization

Organization • Structure • Three concepts • • • Span of control Grouping of similar functions Separation of production activities from oversight functions • • • Inspection Control Monitoring • QA • QC • Reliability • Safety

Organization • Span of Control • How many people can you manage • • Higher levels (3 – 7) Lower levels (more) • Grouping of similar functions • Maintain proper surveillance/control • Similar maintenance activities • • • Line maintenance Shop functions Inspection activities

Organization • Separate production/oversight functions • Self-monitoring • • QA QC Reliability Safety • Separation removes conflict of interest • Built into organizational structure

Managerial Structure • Usually starts with VP • VP of maintenance and engineering • • • High level in airline structure Same level as VP flight operations Not directly under: • • Head of airline Operational activity • Five major functions • Technical services • • • Engineering Planning Training Technical publications Computing

Managerial Structure • Five major functions • Aircraft maintenance • • • Overhaul shops • • Flight line Hangar Out-stations Maintenance control center Off-aircraft maintenance Repair Overhaul Material Services • • • Ordering/maintaining supplies Handling warranties Moving parts through system

Managerial Structure • Five major functions • Maintenance program evaluation • • • Monitoring organizational activity Workers Suppliers • Cross-functional coordination • Work together

Technical Services • Engineering specialists - expertise • All engineering functions • • • Development of initial program Evaluation of SBs and SLs for possible inclusion Oversight of incorporation of SBs and SLs Incorporation of ADs Evaluation of maintenance problems from reliability program Establishing policies/procedures for organization • Additional function • Facilities planning

Technical Services • Production planning and control • Maintenance scheduling/planning • • • Manpower Parts, tools Facilities Special assistance Short, medium, long term planning activities Establish standards for man-hours, materials, facilities, tools, equipment Work schedule Hangar control On-airplane maintenance Monitor work progress in support shops

Technical Services • Training • • Course development Curriculum Administration Training records Vendor training OJT for line/hangar personnel Establish new/special training courses

Technical Services • Technical Publications • All manufacturer/vendor documents received • In-house documentation • Format and number of documents for each work center • Revisions • Main/satellite technical library

Technical Services • Computing Services • Selection of hardware/software • • Usage information Input requirements from individual units • Personnel training on computer usage • Computer support

Aircraft Maintenance • Hangar maintenance • Compliance with airline policies/procedures • Support shops • Line maintenance • • • Compliance with airline policies/procedures Turnaround maintenance/servicing Daily checks Short interval checks “A” Checks

Aircraft Maintenance • Maintenance Control Center • Tracks all aircraft in-flight/off-station • Needs coordinated through MCC • Coordinates downtime/schedule changes with flight department

Aircraft Maintenance • Overhaul Shops • Maintenance on items removed from airplane • Engine shop • All maintenance/repair on engines/APUs • Avionics • • Off-aircraft repair Electrical/electrical components/systems • • • Radio Navigation Communications Computers Components

Aircraft Maintenance • Overhaul Shops • Mechanical component shop • • • Actuators Hydraulic systems/components Aircraft surfaces Fuel systems Oxygen Pneumatics • Structures • Components and structural elements • • Composite material Sheet metal

Aircraft Maintenance • Material • Purchasing • • • Parts/supplies Tracking orders Warranty claims/contract repairs • Stores • Storage, handling, distribution • Inventory Control • Parts/supplies on hand sufficient for normal usage rates • Shipping and Receiving • All parts into/out of airline

Aircraft Maintenance • Maintenance Program Evaluation • QA • • • All units adhering to company policies and procedures Sets standard/ensure compliance Auditing outside suppliers/contractors • QC • • • Conduct routine inspections Certifying maintenance/inspection personnel of RIIs Calibration of maintenance tools/test equipment

Aircraft Maintenance • Maintenance Program Evaluation • Reliability • • • Conduct program Problem areas addressed Auditing outside suppliers/contractors • • • Data collection/analysis ID possible problem areas Publication of monthly reliability report • Safety • • Handles claims involving safety issues Safety/health related activities • • • Develop Implement Administer

Variations • Small Airlines • Functions may be combined • Large Airlines • Structure at multiple bases
