The Federal Aviation Administration (FAA) has significantly changed Title 14 Code of Federal Regulations (CFR) Part 145, which governs foreign and domestic air agencies that perform maintenance and alterations on U.S.-registered aircraft, engines, propellers, and appliances. In particular, there is a new provision-14 CFR 145.163-that requires each repair station to submit a training program to the FAA for approval no later than April 6, 2005. To assist industry and FAA inspectors in complying with this requirement, the FAA Flight Standards Aircraft Maintenance Division (AFS-300) requested the Risk Analysis Branch (ATO-P) to research the current state of training and to provide guidance and recommendations for establishing training programs at repair stations. The research team reviewed the FAA's and other aviation authorities' requirements on repair station training and conducted interviews with FAA and industry personnel. The general consensus among those interviewed was that the FAA should specify hourly requirements as well as acceptable content and format for the training programs. Due to the diversity of the maintenance segment of the aviation industry, the challenge for the FAA is to create a reasonable compromise between an acceptable minimum of formalized training at smaller, less complex repair stations without reducing the training offered by the larger repair stations. Based on the 14 CFR 145.163 regulatory requirement, the current state of training at repair stations, and the interview results with FAA and industry personnel, this report offers guidance and recommendations on establishing training programs at repair stations. The report discusses the elements and functions that constitute an effective training program and the recommended number of hours and topics for training repair station mechanics, managers, supervisors, and inspectors.
