With the june 2000 JAR FCL 1 revision, the only multi engine turbo-jet (land) Single Pilot Aircraft were
Aerospatiale MS760 Paris S760. .Cessna C501/551/525
From the latest AGM FCL (february 2002, TGL 4, part 3) it has been changed to
Aerospatiale MS760 Paris S760. .Cessna C501/500SP*/501/550SP*/525
On page 4-1 it states under item 9. that
"At the request by the UKCAA and DGAC-France the Cessna 500 and 550 have been added to the Single Pilot Multi-Engine Turbojet Type Rating list when the aeroplane is single pilot certificated. Note the reference to SP*"
I assume this means that even before JAA, the UK treated all C500/501/550/551 as single pilot aircraft ? I know they are essentially the same, but the 0/1 suffix was meant to be MPA/SPA, right ?
. .Any way, good luck with your operations, whether single or multi pilot ops.
