Is that the propeller of the NGX or something different for earlier airframes
The NGX seems to be a marketing designation, the TCDS designation is PC-12/47E MSN 1720, MSN 2001 and subsequent, fitted with a Hartzell 5-Blade Composite Propeller.
The previous 47E MSN 1576 up to 1944 are fitted with the same Hartzell 5-Blade Composite Propeller (Hartzell HC-E5A-3A/ NC10245B).
Still earlier 47E were fitted with four blade aluminium Hartzell , MSN 545, 1001 to 1575
