REQUESTING SPARE PARTS NAVSUP Forms 1250-1 and 1250-2 are shown in figures 1-15 and 1-16. These forms are used as authorization for drawing parts and requesting requisition of items Not In Stock (NIS) or Not Carried (NC) by supply. It is not a purchase document and does not leave the command. The form must be filled out with either a ball-point pen or typed. Confusion between the number zero and the letter O can be avoided by using the communication symbol for zero. NAVSUP Form 1250 must be signed by the maintenance supervisor or a designated representative when requesting spare parts. It is your responsibility to ensure that the right part is ordered. So, provide the correct information on NAVSUP Form 1250. Instructions on how to fill out this form are located in NAVFAV P-300 and COMSECONDNCB/ COMTHRIDNCBINST 11200.1.

After signature, the form is submitted to the repair parts storeroom. The person receiving the part signs NAVSUP Form 1250-1. The national stock number (NSN), quantity, and price are then documented on the ERO work sheet.

The request for NIS/NC repair parts should be attached to the ERO and returned to the cost control office for review by the maintenance supervisor. The maintenance supervisor then assigns an Urgency-of-Need Designator. The ERO is then passed to the cost control clerk for verification and/or closing. The 1120-1/-2 is then sent to the DTO clerk who records the information in the DTO log and DTO summary sheet. The yellow copy of the ERO is pulled and filed with the DTO summary sheet. Request for repair parts with an Urgency-of-Need-Designator of "A" (NORS) requires the approval signature of the commaning officer who may delegate authority to the company commander (A- 6); an Urgency-of Need-Designator of "B" (ANORS) requires the approval signature maintenance supervisor.

USING PART NUMBERS

To identify the part you need, you must use part numbers. There are two types of part numbers: manufacturer's part numbers and national stock numbers.

Manufacturer - s Part Numbers

Manufacturer - s part numbers are those used by the manufacturer of a piece of equipment to identify each part on that piece of equipment. These part numbers are usually a combination of letters and numbers or all numbers.

National Stock Numbers

Effective September 1974, the United States agreed to replace its federal numbering system with a new 13 digit system that conforms to the NATO stock numbering format. This system is known as the NATIONAL STOCK NUMBER (NSN) system. The 13 digit NSN is broken down into four major groups. The first 4 digits on the NSN is the Federal Supply
