hello HERKY people, we have torque, fuel flow and TIT high bellow crossover which make throttle misalligned bellow crossover. i read some conversations about this issue that are concerned about null start vallue and rich\lean check. null start was not verified but rich\lean check shows 975 deg in null then correct back to 890 deg in auto( -7B engine). my question is this fuel control was shifted rich? if so, correction will be made from temperature compensating bellows at fuel control(CIT)?

Hey Herk friend. One of my Eng/ prop rpm increases upto 105% during opening pwr with freq and then comes to 100% after 6-7 sec with freq 400 Hz. When rpm increases to 105%, then TIT remain 750-800(-7B). After reaching 100% rpm, TIT starts rising. Again while retarding throotles back to Flt Idle, rpm comes to 95-94%( on grd) and 96-97% in flt, then increases slowly with freq. That is in Normal, mechgov and synchro mode. We have replaced VH, FCU, TD Valve,TD amp but no joy. Any suggestions pl.

Anyone see this before I would appreciate any input. Thanks.

Our GTC85-180L APU starts and runs well. However, it doesn't supply bleed air. We have isolated the load control valve. We equally isolated the APU control switch as well as pressure regulator. We cleaned in-line filter. Despite these steps, APU still doesn't supply bleed air. It is strange to us and I am wandering if anyone has had this type of experience before and the possible solution. Thanks.

does anybody experience that: In flight we experience very big vibration( the left wingtip move at least 1 meter up and down), just after the number 1 engine flame out, we shut it down by moving the condition lever in feather then pulling the T handle. The vibration stopped but we have the surprise to see that only 3 blades came in feather position the fourth one stay in position. Sorry if my english isn't as good as i would like.

G'day guys, Got a problem with our flaps. We are getting an asymmetric flap brake condition at approx 10% flaps on extension. We have inspected all flap tracks, screw jacks, rods etc and all look good. Rigging seems to be all within limits. Have checked the switch units at the ends and they are free of moisture and corrosion. Condition is only happening on a steep decent into a higher altitude airport. Any suggestions on where to go from here? We are not wanting to go down the path of a full flap rig if avoidable. Great to be back in the best forum! Have a great C130 day, Tez.
