Aircraft engine maintenance stand. The
aircraft engine maintenance stand, shown in figure 9-3,
provides an essentially nonmovable work station for
repair of aircraft engines.
maintenance stand is designed to allow disassembly
and reassembly of aircraft engines. The rails allow easy
transition of the engine between the engine stand and
the engine trailers. Adapters make the stand useful for
several types of engines.
Principles of operation. The engine
maintenance stand has two rails which allow the engine
to be transferred from the engine trailer to the stand.
There are spring-loaded stops at the ends of each rail to
prevent the engine from accidentally rolling off the
accommodate height difference in engine trailers.
Safety practices and procedures.
The following special precautions should be observed
when using the engine maintenance stand:
· Be sure the rail steps are up unless an
engine is being transferred.
· Push the engine slowly, as its weight
will make the stand hard to shop if it rolls
· Keep the rails level from end to end so
the engine will not have a tendency to
following procedures pertain to the operation of the
engine maintenance stand:
Align the engine trailer rails with the
maintenance stand, both longitudinally and vertically.
Slowly push the engine from the
trailer to the stand, retracting the rail stops at the union
of the rails as the engine adapters go past this point.
Position the engine and secure the
