50. WHEN CHECKED BELOW OR LISTED IN THESE NOTES, DEFINITIONS APPLICABLE TO THIS PRODUCT ARE OR

HAVE:

(A) ENGINEERING CRITICAL IN APPLICATION : An item, which requires special manufacturing processes, controls, and testing of material or end items. Because of its use or application, failure to maintain the highest reliability of such an item could be catastrophic resulting in loss of life or serious injury, loss of a weapon system or extensive secondary damage, with direct impact on the capability to respond to a national emergency or to achieve wartime sustainability.

(B) CRITICAL CHARACTERISTICS : Characteristics which, when defective, are likely to result in hazardous or unsafe conditions for individuals using, maintaining or depending upon the product; or, are likely to prevent performance of the tactical function of a major end item such as an aircraft, missile, space vehicle, engine or a major part thereof. (Derived from MIL-STD-1916).

(C) MAJOR CHARACTERISTICS : Characteristics (other than critical or minor), which, when defective, are likely to result in failure or to reduce the usability of the product or a major end item for its intended purpose. (Derived from MIL-STD- 1916).

(D) MINOR CHARACTERISTICS: All characteristics not designated as critical or major but for which full conformity is required

(E) COMPLEX: Items having quality characteristics not wholly visible (hidden characteristics), in the end product for which contractual conformance must be established progressively through precise measurements, tests or controls applied during purchasing, manufacturing, performance, assembly and functional operation either as an individual item or in conjunction with other items [FAR SUBPART 46.203(b)].

(F). COMMERCIAL: Described in commercial catalogs, drawings or industrial standards [FAR SUBPART 46.203(a), (1)].

When materials, processes or components are to be obtained from directed sources as indicated herein or in the specifications, the contracting officer of this procuring activity may only utilize alternate sources as a deviation upon prior approval.

Bidders shall notify this procuring activity at the time of quotation of any drawing, specification or standard which is of more current data revision than those shown on the data listing or in these engineering notes. The responsible engineering office of this procuring activity will make determination of acceptability of the more currently dated data.

Lower tier specifications listed in or referenced by first tier specifications may not be shown on the data lists or engineering notes accompanying this contract but are nonetheless required by this contract for compliance. Exceptions would occur only when such lower tier requirements have been specifically waived or substitute specifications/requirements are designated herein.

Reports, process sheets, inspection methods sheets and all other documents required by specifications imposed by this contract for contractor compliance which were previously required to be submitted to a prime design contractor shall be held at that facility for review by government personnel.

When prime design source specifications require or provide for participation by that prime source quality, manufacturing, laboratory or engineering support services, these requirements or provisions do not apply when the contract was issued by this procuring activity. For these services or direction pertaining thereto, contact the cognizant government contract administration office or this procuring activity for assistance.

The contractor is responsible for assuring that all dimensions, conditions, tests and test results identified in these engineering notes, applicable drawings, specifications and contract quality requirements are met by themselves and their suppliers. This requirement applies to all characteristics whether those characteristics have been specifically designed as being critical, major or are those minor characteristics not specifically designated as such.

PROCESS DATA REQUIREMENTS (CHECK WHEN APPLICABLE)

______ Prior to beginning of manufacture, the contractor will notify the engineering office of this procuring activity of all manufacturing process and processing procedures intended for use in production of this product. Once these processes are established, no changes shall be made without prior approval of the engineering office of this procuring activity.

SERIALIZATION OF P ARTS (CHECK WHEN APPLICABLE)

_______ Serialization of each part/assembly (contract end item) is required.

STABLE BASE DRAWINGS: (CHECK WHEN APPLICABLE)

OF 6 PAGES

AFLC FORM 2559 (COMPUTER GENERATED) PREVIOUS EDITION WILL BE USED

____X___ When the use of stable base drawings is required, the following shall apply:

A. Stabilize by allowing the stable base drawing to rest flat and unrestrained on a flat surface overnight at room temperature prior to use.

B. Do not stretch or otherwise apply stress.

C. Check the dimensional accuracy of the grid lines. The dimension between adjacent grid lines must be within .005 inch. The grid lines shall be measured vertically, horizontally and diagonally, to insure that the grids are within a tolerance of .005 inch. The tolerance is accumulated over the length and width of the stable base drawing.

D. Trammel points shall be measured to within .010

E. When rolling stable base drawings, do not roll less than 3 inches in diameter.

F. If the above tolerance points prove to be inaccurate, record the discrepancies immediately and notify in writing OC- ALC/PKXDA and the Administrative Contracting Officer (ACO).
