Mach, not aware of that particular version, but at least one operator experimented with locally derived procedures to their detriment.

An issue with the 146 engine was the geared fan; the fan shaft / turbine could windmill relatively fast, whilst the core - oil pump, would be slower or even stop.
As I recall, after an in flight shutdown, if the core stopped or was below 7% the engine should not be relit, because of potential un-lubricated bearing failure.
The fan had to be secured for ferry flights.
