cross-reference lists and such other work of a tabulating nature which may or may not be performed for units directly concerned with the control of stock.

4. Finally, to be responsible for such collateral tabulating work which has no connection to stock control. This work includes payroll tabulation, check writing, financial data, military and civilian rolls, and such other reproduction work as is deemed necessary.

5. To coordinate QSSR program within ASO and initiate instructions to be promulgated to field activities concerning this program.

6. To maintain a complete and accurate reference file of all part numbers, both active and inactive, which have been set up in the Aviation Supply System, and to screen against this file all requests for identification, stock numbering and/or stock classification of items.

Thus we see that the ASO is actually a control organization the director or "policeman" controlling the Aviation Supply System.

Having completed an analysis of the NavAer Organization at the policy level, the Bureau level, and the Supply Demand Control Point level, we now turn to a preliminary study of maintenance, preparatory to an analysis of the organization in the field at the operating level. The FASRON Program embodies supply relationships in the field and forms a logistic pattern for the support of operational consumer activities both afloat and ashore.

Since at this level the Supply-Maintenance relationship is at its closest point, a preliminary review of Aircraft Maintenance will be requisite to a complete understanding of the FASRON Program.

QUIZ

1. In 1946 CNO directed the Chief of the Bureau of Supplies and Accounts to prepare a plan "for the establishment and operation of an integrated supply system." What was the name and date of the plan which grew out of this study?

2. Under the plan referred to in question 1, who is assigned responsibility for the centralized direction and performance of supply functions?

3. Into what two categories were the functions relating to the Supply of Material divided?

4. Name the four levels of control provided for in The Navy Supply Plan.

5. The Aviation Supply Office is a joint agency of the Bureau of Supplies and Accounts and the Bureau of Aeronautics. With what duties is it charged?

6. Which activity of ASO is responsible for the Planning Handbook and the Operating Statistics Handbook?

7. Which activity of ASO maintains control over funds allocated by any bureau or office of the Navy Department for procurement of material and service for the overall aeronautical program?

8. Which activity of ASO obtains and disseminates information on the present and future Naval Aeronautical program and on related logistic plans?

9. Which activity of ASO is charged with the function of coordinating the QSSR program to be promulgated to field activities concerning the program?

10. Which activity of ASO maintains complete records of all material declared surplus by Stock Control Divisions?

Improved Aircraft Maintenance was one of the keynotes to the Integrated Aeronautics Program. The allocation of aircraft maintenance responsibility placed the burden of extensive repair work with continental O & R shops and made afloat and overseas activities responsible for considerably less from a repair viewpoint. While - such general terms may present the "overall picture" of aircraft maintenance, specific problems such as who will have the responsibility for repairing a defective "Phantom" wing or making a modification on a Pratt & Whitney engine, require allocation of such functions in more specific terms.

Accordingly, the Bureau of Aeronautics has defined the different terms used in connection with such maintenance. These definitions, as promulgated in the Manual of the Bureau of Aeronautics, establish approximate limits within which maintenance work performed is known by a common term used throughout the establishment. BuAer goes farther to define the different

classes of maintenance activities ashore and allocates by definition the extent of aircraft maintenance for which each class of activity will be responsible.

Aviation supply personnel are interested in allocation of maintenance responsibilities because, among other reasons, many spare parts required by an overhaul activity are not normally to be used by activities responsible for a lesser degree of maintenance and will be coded by the Aviation Supply Office to so indicate. Other reasons are obvious: The relationship between Maintenance and Supply is so close that knowledge of maintenance problems by supply personnel is necessary for them to render the service required to keep aircraft flying. Because of this close relationship maintenance terms which have universal application throughout the establishment are defined in this chapter. Likewise a knowledge of maintenance classifications of air stations is necessary to the understanding of the Aviation Supply problem. These also are presented herein and they apply to shore activities both in the continental United States and to extra-continental air stations.

DEFINITIONS

AIRFRAME. This term includes envelopes (LTA), hulls or fuselages, wings, stabilizers, vertical fins, controls surfaces, landing gear and nacelles.

ENGINE. This term is applied to that unit of an aircraft which motivates the aircraft in flight.

ACCESSORIES. This term includes airframes and engine accessories, which are defined as follows:

AIRFRAME, ACCESSORIES. Those items which are required for operation of the aircraft and which cannot be considered an integral part of the airframe, such as: wheels, brakes, hydraulic equipment, fuel system, deicing equipment, anti-icing equipment and other items not an integral part of the airframe are airframe accessories.
