Government contracts often include first article testing (FAT) requirements to ensure the contractor can supply a product that meets the contract requirements for acceptance. Such contracts incorporate the clause at FAR 52.209-3 (Contractor Testing) or FAR 52.209-4 (Government Testing) to impose FAT requirements on the contractor. Both clauses allow the government to waive the FAT requirements where the contractor has previously furnished supplies of identical or similar items that the government has accepted. An improper waiver of the FAT requirements that is inconsistent with the relevant FAR clause may be grounds for protest. In such protests, it is the procuring agency’s burden to establish that its decision to waive the FAT requirements was reasonable and in accordance with applicable procurement law and regulation. In addition to prior successful performance, if the agency can demonstrate that the contractor in question previously received FAT approval for the same items being procured, the Government Accountability Office (GAO) will typically not sustain the protest challenging the FAT waiver, unless the protester can present countervailing evidence that the item being supplied will not meet material solicitation requirements.
In B-423244, a decision issued on March 11, 2025, the GAO denied a protest challenging the agency’s decision to waive FAT requirements because the contractor had successfully delivered the items being procured on a previous contract and had obtained a FAT approval on that contract. The Defense Logistics Agency (DLA) issued the relevant request for quotations (RFQ) for air duct hose assemblies identified by National Stock Numbers (NSN). The RFQ required the relevant hose assembly to be manufactured in accordance with a particular military specification and also included the clause at FAR 52.209-3 to mandate FAT approval. When the award for the relevant air duct hose assembly was made, the contracting officer (CO) elected to waive the FAT approval requirement pursuant to FAR 52.209-3(h) based on the awardee’s successful prior delivery of the identical item under a previous contract. The record expressly noted that the awardee had supplied the air duct hose assemblies identified by the same NSN through the same manufacturer and had previously received FAT approval from the agency.
In the protest that followed, the protester argued that FAR 52.209-3(h) only permitted a waiver on a subsequent contract when the contractor had previously secured FAT approval under a prior contract. Furthermore, even though the awardee’s supplier had previously obtained FAT approval on a prior contract for the same item, the protester maintained that the agency improperly waived FAT approval for the current procurement because the prior approval was obtained under a less rigorous standard. Meanwhile, the agency argued that the plain language of FAR 52.209-3(h) did not specifically require prior FAT approval but permitted a waiver whenever identical or similar items had been previously furnished by the contractor and accepted by the government. Additionally, the DLA argued that even if the protester’s interpretation of FAR 52.209-3(h) as requiring prior FAT approval was correct, the protest should be denied because the awardee’s supplier had previously obtained FAT approval for the identical product, thereby justifying waiver of FAT requirements in this instance.
In beginning its analysis, the GAO noted that the DLA had cited a prior decision from 2015, in which the GAO had agreed with the agency’s interpretation of FAR 52.209-3(h). Specifically, the GAO had previously held that under FAR 52.209-3(h), the agency’s decision to waive FAT requirements did not need to be contingent upon whether the contractor had previously received FAT approval for similar or identical items. Instead, the clause permitted waiver whenever identical or similar items had been previously furnished by the contractor and accepted by the government. In any event, the GAO noted that the FAT waiver at issue here was expressly based on the prior FAT approval for the same item being procured. Thus, the disparity between the protester’s and the agency’s competing interpretations did not need to be resolved, as the awardee had previously obtained FAT approval for the item. The decision noted that the prior approval was in addition to the contractor’s successful performance on the previous contract for the identical item with the same NSN, manufacturer, and governed by the same military specification. As for the protester’s argument regarding the government’s prior acceptance of the first article being inadequate, the GAO explained that such matters were not within its bid protest function, as they related to contract administration, and denied the protest.
When applicable, FAT requirements serve an important function in supply contracts by ensuring that the contractor can furnish a compliant product. In fact, if the contractor is unable to obtain FAT approval, the contract may be terminated for default. Per FAR 52.209-3 and FAR 52.209-4, the government may waive FAT requirements, where supplies of identical or similar items have been previously furnished by the contractor and accepted by the government. In this regard, the plain language of the FAT clauses does not specifically require prior FAT approval, provided identical or similar items have been previously delivered by the contractor and accepted by the government. As demonstrated in the protest above, in addition to such successful performance on a prior contract, the procuring agency may also present evidence of prior FAT approval for identical items in support of its waiver decision. When protesting the government’s waiver of FAT requirements in such cases, rather than challenging the adequacy of the prior FAT approval, protesters should instead focus on presenting compelling countervailing evidence that the item at issue will fail to comply with material solicitation requirements.
