The RIII inspector was present during the testing of five patches on August 22, 1979, and the testing of one additional patch on August 23, 1979. Each patch was first checked using the pulse echo method, a field sketch was made of the patch and Mr. Muenow predicted what would be contained in the patch by documenting these predictions on the sketch.
Aft.'r that, the test results were verified by chipping the patch out.
Mr. Muenow predicted that five of the six patches would have defects in them and that the sixth patch appeared to be bonded and solid.
