MIL-STD-849B

5.1.3.1  Examination of items.  Each parachute assembly or component thereof will be inspected for all manufacturing operations and material requirements that have not been previously inspected and accepted through in-process inspection.  The misassembly of any components or individual parachute system will be cause for rejection.  The acceptance number for major/critical defects shall be zero and the number of minor defects shall not exceed the quantities set forth in table I, II or III.

5.1.3.2  Examination of cloth, tape, and webbing.  The cloth, tape, and webbing shall be examined visually to detect holes, snags, strains, stains, or other defects.  Unless otherwise specified herein, encountered defects shall be classified in accordance with the classification of defect tables in the applicable material specification.  Any material defects in the finished canopy (regardless of cause) that are minor will be acceptable, and any major/critical defect will be cause for the canopy to be rejected.

5.1.3.3  Examination of seams, hems, and stitching.  The seams of canopies and pilot chutes will be examined for conformance with drawing details by projection of a 40-watt (minimum) fluorescent light through the canopy.  Canopies made from tape and webbing shall be examined visually.  Seams and hems shall be examined for the proper number of stitches per inch, broken or missing stitches, and proper construction.  Defects discovered during these examinations will be classified in accordance with the classification of defect tables herein.

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)

6.1  Intended use.  This document is intended for defining the major/critical and minor classifications necessary to determine the acceptability of various parachutes for Government procurement purposes.

6.2  Past usage.  Definitions of defects were previously provided in MIL-STD-105, "Sampling Procedures and Tables for Inspection by Attributes".  General quality assurance terms were specified in MIL-STD-109, "Quality Assurance Terms and Definitions".  These standards are no longer referred to in this document.
