Footnotes

a) i) Engines with one or two fuel valves per cylinder: one set of fuel valves, complete.

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

b) The spare parts may be omitted where it has been demonstrated, at the Builder's test bench for one engine of the type concerned, that the engine can be maneuvered 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.

Notes:

1 The availability of other spare parts, such as gears and chains for camshaft drive, should be specially considered and decided upon by the owner.

2 It is assumed that the new crew has on board the necessary tools and equipment.

3 When the recommended spares are utilized, it is recommended that new spares are supplied as soon as possible.

4 In case of multi-engine installations, the minimum recommended spares are only necessary for one engine.

5 For electronically controlled engines spare parts as recommended by the engine designer/manufacturer.
