Abstract:

Magnetic tapes of vibration from 12 cylinder, AV-1790-7 engines before and after repair were analyzed. A computer program OP-SEEKER determined from the vibration which engines were faulty needing repair and which were not. Although only 6 different engines were examined a larger sample size would have been a better test of OP-SEEKER, 100 success was obtained.
