hi. Recently, an oil filter defect occurred in one engine continuously. I checked the filter and checked it out and found that the filter and support were purple. All the filters in the whole line were purple. Have you ever experienced this?

Hey guys Here's a problem that has me stumped. Engine starts up to LSGI (auto & null TIT peaks about 810°C). When upshift to NGI engine rpm is 95% and generator will not come on line. You need to manually reset ON or move throttle to speed up the engine. All engine parameters are good at all throttle settings, IBIT check good. Only GI/FL rpm is lower than usual, but not out of limit. Generator circuits check good, with all relays, control panel etc having been replaced, and even generator replaced. Any thoughts on this issue would be appreciated PJ

We have a 74 model H1 with AN/AWY-1 single system autopilot, (Air Force Standard Flight Director, C12 Compass, single INU) that has had a perplexing discrepancy for a few years. With the FDMS switches in SCNS, AP2 selected on the FCP and LNAV/NLOC selected on the mode select panel the write up reads as follows "AP2 will not capture beam with SCNS selected". During the ops check with switches in the aforementioned positions the "N/L ARM" display on both pilot and copilot FPWU annunciators remain on and they never go to "N/L CAP". When AP1 is selected and all switches as listed, they system works as advertised and immediately the N/L CAP annunciator comes on. With that …

Fuel control roughly 60 rich. Push throttle above crossover tit corrects roughly 820. Pull throttles just below crossover tit stays at 820. Below crossover tit will only correct back when switch is placed to NULL. All TD ops checks work as advertised. Valve is going to a locked position below crossover with the switch in AUTO. Considering the valve works like a champ in AUTO and also in locked not suspecting the valve to be the culprit. Changed AMP, coordinator, & relay box. Have never come across this issue before any ideas?

This is a collection of experience-obtained information about C-130 troubleshooting for systems assigned to what the USAF used to call "A/R Shop"...flight controls, landing gear, doors, and ramp. This was written for various versions of the E-model fleet back when, but probably applies in most instances to the newer models as well, since the "A/R Shop" systems haven't changed much, if at all. Use your judgement and technical requirements if you choose to refer to this publication...regard this information as helpful hints, nothing official. Hope it helps!

For several weeks flight and ground crews have been pecking away at a problem where engine torque, fuel flow and TIT increase when engine anti-icing is turned on. We're not talking 100"lbs of torque here, its over 4000"lb and/or 300 to 500 pph of fuel. Every conceivable component from FCU, speed valve, anti-icing side valves, and the whole TD system has been replaced at least once with no change. Last week the engine was finally removed and sent to test cell. Engine was started, runs great, makes good power, but when anti-icing is turned on there is a massive surge of torq and fuel which the TD barely contains. I had the to see what …

I am wondering if anyone can advise when the manual override button located on the Rudder Boost Diverter Valve would be used? We have imagery but no actual technical notes advising of what the intent of the button is other than a manual override. We are guessing it is in case the hydraulic pressure does not change when the flaps are raised/lowered beyond 15% but we are not 100% certain. This is on a C-130J but was also used on the H and E models. Thanking for any assistance in advance.
