Like Bravo73 wrote, there is an AS332 at HeverControl.com, it was made for the FS2004 but it works in FSX. You will only need to work a bit with the installation:
- Download the Super Pumas package from
here
unpack it witch WinRaR, and run the install program
- When it'll ask you for FS9 directory, write in some temporary one, like "C: \Temp\SuperPuma\" it will install all files there just like it would in FS9
- then go to that directory, copy 'Effects', 'Sound' and 'Gauges' folders into FSX directory.
- open the 'Aircraft' folder and copy whole 'as332gjsar' into 'Flight Simulator X\SimObject\Rotorcraft'
Then run the sim... the a/c is quite butt-ugly, but if you need it for IFR it may do - the 2D panel is nicer than VC though.
