MIL-HDBK-6870B
should be approved by the NDIRRB. If necessary, a POD study should be conducted to verify the detection capability of the NDI processes. Further guidance on POD studies can be found in MIL-HDBK-1823.
7.5.1 Procedure validation.
Procedure validation should be the responsibility of the author of the procedure unless contracted by a government organization. The process for performing and documenting procedure validations should be approved by the customer and should accomplish the following objectives:
a. Collect and analyze supporting data.
b. Establish appropriate method, equipment and procedure parameters.
c. Establish requirements for unique reference standards to effectively control set-up variability.
d. Establish appropriate technician skill-level for reliable procedure performance.
e. Establish appropriate component removal and surface preparation requirements necessary for adequate access.
f. Design/manufacture test specimens containing actual or simulated discontinuities. g. Design/manufacture prototype support equipment.
h. Produce a draft technical procedure.
i. Demonstrate procedure feasibility to responsible NDI Level III (reference NAS 410). j. Approval of the procedure by the responsible NDI Level III (reference NAS 410).
7.5.2 Procedure verification.
Procedure verification will be performed immediately following the conclusion of successful procedure validation. The verification process must prove the suitability of an NDI procedure to perform its intended purpose to the satisfaction of the end user, the responsible NDI Level III, the depot NDI program manager and the responsible program engineer. Verification will be performed on an aircraft or on an individual assembly or component as directed by the inspection procedure. Verification will also be conducted within a representative environment on actual aircraft parts or test pieces by representative inspectors.
Procedure verification must as a minimum accomplish the following objectives and be documented using a Qualification Checklist approved by the NDIRRB and government:
a. Ensure the procedure is thorough, understandable and logically written.
b. Ensure the procedure is understood and executable by the lowest skill level projected for flight test and in-service use.
c. Ensure the specified equipment performs as expected and is readily available to the intended end-user.
d. Ensure the specified part preparation procedures are logical and can be accomplished as written.
e. Demonstrate the procedure meets expectations for detection capability and false call propensity.
