备注:
1)  In case of multi-engine installations, the minimum recommended spares are only necessary for one engine.

2)
 a)  Engines with one or two fuel valves pr. cylinder: one set of fuel valves, complete
   b)  Engines with three or more fuel valves pr. cylinder: two fuel valves complete per cylinder and sufficient number of valve parts,  excluding the body, to form with, those fitted in the complete valves, a full engine set.

3)  The spare parts may be omitted where it has been demonstrated , at the builders test bench for one engine of the type concerned, that the engine can be manoeuvred satisfactorily with one blower out of action.

The requisite blanking and blocking arrangements for running with one blower out of action are to be available on board.
