1. First Article Test (FAT). Paragraph 6.2 d. of Mil-DTL-43649.
1.1 Acceptance criteria for the FAT. The following provides the acceptance criteria for the FAT. Any end item visual defect, major or minor, per Mil-DTL-43649 tables I, II, and IV; any dimension out of tolerance; nonconforming supplies or failure of the test as specified in 4.2 shall be cause for rejection of the FAT.
1.2 Conformance Inspections. Paragraph 6.2 e of Mil-DTL-43649.
a. End Item Visual Examination.
Canopy with Riser. The canopies shall be examined for the applicable defects listed in Mil-DTL-43649 table I. The lot size shall be in units of canopies and risers. The sample unit shall be one canopy and riser. The inspection level shall be S-2 and the acceptable level (AQL), expressed in terms of defects per hundred units, shall be 1.0 for major defects and 6.5 for total (major and minor combined) defects.
Deployment Bag. The bags shall be examined for the applicable defects listed in Mil- DTL-43649 table II. The lot size shall be expressed in units of deployment bags. The sample unit shall be one deployment bag. The inspection level shall be S-2 and the AQL, expressed in terms of defects per hundred units, shall be 1.0 for major defects and 6.5 for total (major and minor combined) defects.
Static Line. The static lines shall be examined for the applicable defects listed in Mil- DTL-43649 table IV. The lot size shall be expressed in units of static lines.
