A method was developed for anticipating maintenance job requirements and thereby reducing the time lag between the introduction of new equipment and the availability of sufficiently trained personnel. A job analysis based on the construction, malfunctions, and methods for correcting the An/APQ-24 radar set was applied to Q-24 prototype data and compared with a similar analysis of actual production models. The similarity of the results of the 2 analyses suggested that the Q-24 mechanics could have been trained before the Q-24 models were in use. A standard maintenance form was designed to aid in the collection of data. (See also AD5864).
