Classification Of Parts For Maintenance/Repair - Rotax MMH-912 Series Maintenance Manual

9) Classification of parts for maintenance/repair

See Figs. 00-3 and 00-4.
As for an overhaul, parts for maintenance/repair must be classified. They are classified
either as "parts usable" or as "parts to be replaced".
The classification is made on the basis of the following criteria:
– Hours of operation (decisive are the total operating hours of the part / engine or
hours since the last overhaul)
– Determined (measured) actual dimension of the respective parts.
– See Figs. 00-3 and 00-4 for the classification of such parts.
Proceed as follows:
– Determine wear as a percentage of the wear tolerance
(see the dimension sheets attached directly after each section for the wear limit
(100%) of the part in question).
– Determine the hours of operation for the part in question (see Log book etc.)
