LOW-COST maintenance is secured by attacking the problem before the design is started. The author tells how this important feature can be designed into the airplane. Maintenance requirements should be written into the contract specifications which should indicate the time within which each part should be inspected and serviced. A suggested set of such specifications is submitted. By this procedure maintenance time can be cut in half.
The work of designing must not be rushed. To provide for quick maintenance, some broad changes from customary design are needed and will add to first cost but save money in the long run. Numerous recommendations are made as to design or type of important elements which will facilitate maintenance, avoid exasperation and add to passenger safety and comfort.
