Things to watch (5)

Serious: Government has no technical data for these items. You must repair these navigation units without Government drawings or data rights, so you need your own repair data, test equipment and parts sources.
Serious: Unit of issue not stated. The list gives quantities per fiscal year but no unit of issue, and a price quote is set per unit. Ask the buyer what a quantity of 12 or 100 counts.
Worth checking: No physical samples available. Samples of the items cannot be had to evaluate the repair work, so planning must rest on the part numbers alone.

Show all 5Show fewer

Worth checking: Contractor supplies all equipment and parts. You must furnish and calibrate all support and test equipment and all replacement material at your own cost.
Minor: Item list may change. The Government may change which items and quantities it needs in later correspondence, and answering this survey does not guarantee a place in a later solicitation.
