Hello all.

Were having an issue with our ICS system on our planes. We have Navy C-130T's BUNO# 164995 that just got back from mod and all stations are weak when they transmit on ics. Hot mic, Call, and the radios all work 4.0. These are downing our birds and we can not figue out what the issue is. Does anyone have any ideas?

Thanks!!

Hey all,

We have C-130T A/C. Were having some issues with our #1 and #2 c-12 compass system. For #1, #1 COMPASS SYSTEM STICKS IN VARIOUS HEADINGS. WHEN SLEWED AT CONTROL HEAD COMPASS HEADING UNSTICKS AND WORKS AGAIN. For #2, #2 COMPASS RATCHETS +/- 7 DEGREES IN MAG AND DG (SWAPPED CONTROL HEADS, AMPLIFIERS AND DIRECTIONAL GYROS, NO JOY) RAN UP #2 COMPASS DURING TURNS. VIBRATION CAUSES GYRO TO DEVIATE WORSE THAN WHEN STATIONARY. We replaced the Gyro for #2 and still no joy. Any Ideas? Thanks!

Thanks NATOPS1.....any ETA on a fix yet?

Ok, just got back to work from the weekend. Realized that all of our birds have this gripe written up with the altitude alerter mod. None of them capture altitude.

They updated out altitude alerter some 6 monthgs ago i believe. would it have anything to do with a possible bad adc sending wrong veritcal error codes? This gripe is still haunting us.

The discrepancy still remains unfortunetly. It happens regardless if T.D. is in AUTO or NULL. Yesterday when we were turning, as soon as the #4 Prop Ice control switch is activated, the #4 TIT drops 10 degrees, and then flux +- 5. We're going to try and swap guages when we turn, since we had to replace the #3 TIT guage(froze up while turning last night).

Were having an issue with one of out C-130T engines. We had a flight come back with a #4 engine TIT flux of +/- 40 Degrees in the air, and +/- 5 degrees on the ground when #4 prop anti-ice/de-ice switch is turned on. Both indications happen in auto or Null. When the prop anti ice is turned off TIT returns to steady and solid. Any ideas of what it could be?
