An/arc-190. Had hf 1 and 2 coupler fault pop up mid flight. Would rx but no tx or tune tone. Repressurized #1 coupler and both started started working again. Didn't make sense to me why #2 would start working other than the rf interlock relays are the only thing that shares a connection (i believe). However, sys would work fine until the next day, and the same problem returns on both system. Repressurized #1 again and both starts working. Anyone seen due to hf 1 fail, to cauaes #2 to fail as well? Could this coupler be losing pressure over night? Dont have any parts so im trying to narrow it down

We had an incident where one of the propellers on an aircraft went into an uncommanded reverse. Has anyone experienced this? It is the first time in (our) history that something like this has happened. It is still under investigation and is of huge concern to us because this incident happened on a pre-take-off run. Any suggestions/help will be appreciated!

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.

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.
