Summary

3. Introduction
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

4. Grouping of Similar Functions
Organizational Structure
Three main concepts:
Span of Control
Grouping of Similar Functions
Separation of Maintenance Activities from Oversight

5. Levels of Management determine # of personnel
Span of Control
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

6. Grouping of Similar Functions
Grouping under One director, manager, or supervisor for like tasks:
Refer to Fig. 7-1 pg. 86

7. Separation 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

8. Maintenance & 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

9. Maintenance 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

10. Technical Services Engineering
Development of the initial maintenance program
Tasks, intervals, schedules, etc.
Evaluation of service bulletins/letters for possible inclusion into the airline's equipment or practices
Oversight of those SB/SL deemed beneficial
Oversight of airworthiness directives required by regulatory authorities
Evaluation of problems identified by the reliability program and any problems from maintenance checks
Establish the policies and procedures for the M&E organization
Involved in planning of facilities to ensure it meets M&E requirements

11. Technical Services Production Planning and Control
Responsible for maintenance scheduling and planning
Manpower, parts, facilities, tools and special assistance for maintenance or modifications
Functions include:
Short, medium and long term M&E planning
Establish standards for manhours, materiel, facilities, tools and equipment
Work scheduling
Control of hangars
On-aircraft maintenance
Monitor progress of in-work maintenance

12. Technical Services Training Technical Publications Computing Services
Curriculum, course development, administration, and training records for all personnel
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

13. Aircraft Maintenance Three functions: Flight Line Maintenance
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

14. Overhaul Shops Engine Shop Avionics Shop Mechanical Component 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

15. Materiel (Supply) Responsible for: Purchasing
Stocking and distribution
Inventory control
Shipping and receiving
To include M&E and administration and management

16. Maintenance Program Evaluation
Quality Assurance
Ensures adherence to company policies and procedures as well as FAA requirements and those of suppliers
Conducts periodic audits to ensure compliance
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

17. Maintenance 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

18. Summary 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

19. Small 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
