NDT Services in San Antonio, TX
Operators in San Antonio, TX run NDT scopes against a tight set of compliance expectations. The industrial mix here — oil and gas support, aerospace mro, usaf — pulls inspection work toward FAA Part 145, NAS 410, which means a contractor needs documented Level II/III currency, traceable instrument calibration, and on-call ASNT-recognised method coverage before the first survey starts.
Mid-continent gas processing and USAF MRO both use NDT subcontractors — bridging the two compliance frameworks requires unified cert and equipment records.
