Bell 412EP
Hi folks, we are having an issue with a B412EP that has PT6T-3D power sections. We can't seem to get our accel checks times down enough. What we have done so far is switched out the TCU(-01), cleaned the P-3 filters. Checked for air leaks. Our accel times are running around 6 secs to low of 4.99 so needless to say for the altitude and temps, we are not meeting our times. we have maxed out our dome adjustments( 6 clicks on this one) and only get a difference of 0.5 sec. This is both power sections, we did a power assuarnce and our temps are good, ITT margin is good...running out of options save switching out AFCU or bleed valves. Question two is will a -01 TCU cause issues with running -2 governors? There is a bullentin out, but for some reason we got our twin pac shipped like this. Any takers/advice on this one? Feel free to PM me.Thanks.
