IntroductionIntroductionIntroductionIntroduction Key point: The organizational structure must

allow the company to meet its goals and objectives and each unit within the company must be endowed with sufficient personnel and authority to carry out those objectives and meet those goals

Three main concepts: Span of Control Grouping of Similar Functions Separation of Maintenance Activities

from Oversight

Organizational Structure

Amount of personnel or activities one can effectively supervise of control

By limiting the number of people that a manager has to supervise, the work is divided and the organization is run more efficiently

Levels of Management determine # of personnel

Higher usually lower personnel Lower line maintenance - more

Span of Control

Grouping of Similar FunctionsGrouping of Similar FunctionsGrouping of Similar FunctionsGrouping of Similar Functions

Grouping under One director, manager, or supervisor for like tasks:

Refer to Fig. 7-1 pg. 86

Separation of Production & Oversight FunctionsSeparation of Production & Oversight FunctionsSeparation of Production & Oversight FunctionsSeparation of Production & Oversight Functions

FAA rules require oversight/self-monitoring functions of own rules and those of a regulatory authority

QA, QC, reliability and safety programs

Must be separate to avoid conflict of interest

Maintenance & Engineering Organizational ChartMaintenance & Engineering Organizational ChartMaintenance & Engineering Organizational ChartMaintenance & Engineering Organizational Chart

The M&E department is responsible for conducting all scheduled/unscheduled maintenance, modifications within the limits of the maintenance schedule and still meet the flight schedule.

OPS is responsible for the flight planning, to include flight crews, crew training etc.

Both the VP of M&E and OPS will have equal weight…one can NOT exist without the other

Maintenance OrganizationMaintenance OrganizationMaintenance OrganizationMaintenance Organization Five Major Functions:

Technical Services Engineering, planning, training, technical publications, and

computing Aircraft Maintenance

Flight line, hangar, outstations, and maintenance control Overhaul Shops

Off-aircraft maintenance, repair, and overhaul Materiel Services

Ordering and maintaining supplies, handling warranties, and moving repairable and consumable parts through the system

Maintenance Program Evaluation Monitoring activity for the organization, its workers and its

suppliers

Able to establish new and special training based on needs of the aircraft

New equipment, modifications, test procedures etc.. Technical Publications

Maintains Master Library with list of all documents, too include number of copies and format – paper, microfilm, or electronic media

Responsible of tracking and issuing all revisions to respective work centers

Must do periodic checks to ensure condition and current Computing Services

Selection of software & hardware – with usage information and requirement input from the individual

Training of M&E personnel on usage Continuing support

Aircraft MaintenanceAircraft MaintenanceAircraft MaintenanceAircraft Maintenance Three functions:

Flight line maintenance, hangar maintenance and Maintenance Control Center

Flight Line Maintenance Turnaround maintenance and servicing, daily checks,

short interval checks and minor modifications Hangar Maintenance

Repairs, modifications, engine changes, painting, corrosion control

Support shops – welding, seat and interior fabric, composites and GSE

Maintenance Control Center Tracks all flights in and out, and maintenance needs

Overhaul ShopsOverhaul ShopsOverhaul ShopsOverhaul Shops

Engine Shop Repair on types of engines and APUs

Avionics Shop Radios, navigation, radar, communication,

electrical Mechanical Component Shop

Actuators, hydraulic systems, flight control surfaces, fuel systems, oxygen, pneumatics, etc.

Structures Sheet metal and other structural elements

Quality Control Routine inspections of maintenance and repair

work Certify maintenance and inspection personnel Manage the (Required Inspection Items) RIIs

program Calibration of tools and equipment Oversees the NDT/NDI /program procedures

Maintenance Program EvaluationMaintenance Program EvaluationMaintenance Program EvaluationMaintenance Program Evaluation

Reliability Ensures that any problem areas are addressed Data collection and analysis and publication of

monthly reliability report Safety

Develops, implements and administers the safety and health related activities for M&E

Handles all reports and claims

Summary of Management LevelsSummary of Management LevelsSummary of Management LevelsSummary of Management Levels

Responsible for all outlined Administrative and personnel duties Budgeting and planning (long and short

term) Necessary interaction

Meetings, letters, seminars, conferences etc… Management has determined structure

based on requirements to meet goals and objectives of organization

Small AirlinesSmall AirlinesSmall AirlinesSmall Airlines

All activities are addressed regardless of size although some may be combined

i.e. quality control functions to qualified maintenance personnel

Technical publications, training, and production planning and control may be under engineering

Line and hangar maintenance may be separate departments but utilize same personnel based on quals, certifications and skills

May not have own hangar maintenance – may have to subcontract
