There are many incorrect rumors running around here.
Here are some of the facts:
1) The S-76D program is still on track for certification during the 1Q of 2009.
2) The program has stepped up to the plate to bring the cert basis up to be at least 92% compliant to the latest FAR/JAR amendments (currently working to make this value even higher).
3) The fuel capacity has indeed increased by 15 gals. The S-76D maximum range however will increase to greater than 400nm with the improved fuel consumption that the PW210S engine offers.
4) The PW210S has run in the test cell up to and including max takeoff power. The engine runs great.
I hope this helps to set the record straight.
