Inspection Control Learning Module

Inspection Control Tutorial

Inspection Control Module Objectives

This module covers Inspection Control and Personal Warranty by presenting the basic principles, main areas and key objectives of inspection. It also discusses Inspection Assurance, as one of many quality assurance procedures. Proper inspection is a fundamental task in quality assurance.

To better understand the role of inspection in the aerospace industry, this module's structure is strongly based on NASA's SMA Technical Excellence Program (STEP) - "Inspection Control and Personal Warranty", SMA-QE-WBT-252 and "Inspection", SMA-QE-WBT-251, courses [1], images and content are courtesy of the NASA STEP program.

In this module we will cover Inspection Control and Personal Warranty, which deals with quality status stamping. Quality status stamping is the process of physically or electronically marking a product or paperwork to attest that specific tests, processes or standards have been met. You will become familiar with Personal Warranty and the significance of assuring work with your personal mark. This is the first step in familiarizing yourself with product and process assurance activities that utilize the inspection process and your personal warranty. It is not intended to make you an expert in inspection control, however, it will provide you with the understanding you need to speak knowledgeably with colleagues on a manufacturing project.

After the tutorial you should be able to recall the following:

  • How products are controlled with the use of an inspection control system.
  • The meaning of personal warranty.
  • The responsibilities of mission assurance personnel in inspection control.
  • The supporting roles of management, engineering, and planning in inspection control.
  • The differences between NASA stamps and contractor stamps. Reasons and ways to assure the traceability of stamps.
  • How stamps are applied.

 

 

In the second part of the tutorial, you will become familiar with the basic principles of product inspection. It has been developed to ensure that every product built for NASA conforms to requirements. When you have completed the module, you will be able to:

  • Explain the concepts and timing of inspections leading to product acceptance.
  • Describe the role of Quality Engineering in specifying product inspections.
  • Explain the concept of Personal Warranty and Stamp Control.
  • Identify the industry standards and NASA source documents that govern inspection.

This module is based on the STEP (SMA Technical Excellence Program, SMA-QE-WBT-251 and SMA-QE-WBT-252).

This course is recommended for Quality Assurance personnel who perform Quality Engineering and Inspection functions related to the acceptance of critical or complex hardware and software products. This would include Flight Hardware and Software and its Interfacing Ground Support Equipment.
Others who may benefit from this course are all other Quality Assurance personnel, and Engineering or Operations personnel involved in the design or acceptance of critical or complex hardware and software products.
