5.3 Unusual Damage Evaluation. The Government may request the Contractor to submit an inspection condition report, pictures of the damage, and a repair quote listing all parts and labor needed to return the component to serviceable condition that meets CMM specifications. The quote shall include the task order number, line item number, NSN, P/N, and S/N of the component. The hourly labor rate shall be charged at the firm-fixed rate established in the Schedule under CLIN 0004 and subsequent Option Period CLINs. The quote shall not include the work involved in the teardown and inspection, which will have already occurred, as this is covered by the firm-fixed price specified under CLIN 0001 and subsequent Option Period CLINs in the Schedule.

The Contractor’s delivery obligation shall stop from the date of notification that an item has been determined to be a candidate for “Unusual Damage Evaluation.” The delivery obligation will be specified in the task order modification and will apply only to those items specifically addressed by the modification. The Contractor is obligated to deliver all other components not individually addressed by the modification under the original delivery date specified on the task order.

The KO shall either initiate negotiations for a firm-fixed repair price with the Contractor or if repair is not desired provide disposition instructions for the component. Authorization to proceed with repair work or disposition instructions if repair is not authorized shall be given via issuance of a task order modification. If a component is returned to the USCG in a disassembled condition, the Contractor shall be entitled only to the T&E Fee established in the Schedule of Supplies/Services under CLIN 0002 and subsequent Option Period CLINs.
