Aircraft Engineering THE MONTHLY SCIENTIFIC AND TECHNICAL ORGAN OF THE AERONAUTICAL ENGINEERING PROFESSION makes up his mind exactly how his part of the operation is to be performed. After this a series of conferences is held during which E publish in this issue another of the articles which have these individual decisions are discussed and a schedule drawn up appeared from time to time in AIRCRAFT ENGINEERING on laying down precisely by whom and at what time—and this matter of W the organization of the maintenance and repair of aero timing may be said to be the crux of the whole operation—each job planes, the principal examples of which it is perhaps interesting to is to be done. It is not difficult to see the enormous amount of time recall here. The subject was dealt with at some length in the course of and wasted effort that can be saved over the alternative method of an exhaustive series entitled 'Air-Line Engineering Management' by letting loose a horde of workers simultaneously all over the aeroplane. M R IVOR LUSTY which, although they date back to 1942 and 1943, are Incidentally, a secondary advantage of this detailed breaking down still looked upon as something in the nature of a 'classic' by those and planning is that it has enabled A.M.S.D.U. to make use of a qualified to know and remain available in our reprint form. considerable proportion of National Service short-period, and there There was not, naturally, much publishable on the matter during fore at best only semi-skilled, personnel on the work. the war years but we returned to it during 1948 with 'The Planning of Aircraft Maintenance' by R.

In addition to these is in the periodicity of the coming in of the aeroplane for servicing, general articles of broad outlook, during 1946 and 1947 a number arising from the differences in the operational schedules. Also, and dealt with more detailed aspects of maintenance and repair, this is the reason for the amount of time initially spent on a close from which we may pick out for mention, for a reason which will examination of the aeroplane purely from the servicing point of appear shortly, 'Servicing Advantages of the Jet-Propulsion Engine' view, is that, at any rate with the types so far being operated, by S.

One of the points that was brought out in the graph published with the article on 'Servicing Advantages of the Jet-Propulsion Engine' The Root of the Matter (to which we referred earlier) is that considerable unserviceability of an aeroplane is caused by the removal of parts at inspection times The whole art of planning the detailed servicing of a given aero merely to check that they are all right, when in fact it is frequently plane is so to arrange it that each individual operative can be put to work at a definite place in the machine at the moment when he can found that they are in perfect condition. To overcome this un work efficiently and uninterruptedly on a specific part without inter necessary disturbance, and avoid the aeroplane being withdrawn from service on account of it, a system of card-indexing such as that being fering with, or being obstructed by, others. To ensure this the operated by A.M.S.D.U. is necessary, on which a detailed record is aeroplane must be 'broken down', very similarly to the procedure kept of how often a given item of equipment really needs attention followed in production assembly, into a number of sections or components. On the care and foresight with which this is worked out so that in course of time precise information may become available the whole efficiency of the operation depends. The undoubted success as to how often it is actually necessary to examine it. This analysis is one of the most fruitful steps towards the full economic utilization of the AIR MINISTRY SERVICING DEVELOPMENT UNIT is due to the of an aeroplane.
