The GE voltage regulator burns each time we run the engine. We have replaced 3 voltage regulators and they all got burnt. We also replaced generator. When we installed Bendix, we had high voltage. Anyone with idea of what could be causing this?

I am working on a 130J which is converted to a maintenance trainer. after the ramp was lowered to ADS position i found the manual dial set at #5. the ramp locks are extended with the ramp open. I am unable to retract the locks manually. setting the dial at #1 will raise the ramp but will not disengage the locks. basically i am unable to close the ramp. note: that the Elect/HYD function from the Aux pump has been disabled due to our tear-down process. Any ideas would be appreciated. Note: Fault isolation manuals states to replace the manifold.

Hello, I'm an engineer working on Pallet Loaders/K-Loaders. I want to understand about the cargo loading and unloading procedures, specifically the use of Pallet Loaders and forklifts. When is a pallet loader used and when is a forklift used? Pallet loaders can only provide a horizontal movement of the pallets from and to the aircraft. Since forklifts are required for the vertical movement from and to the dunnage, then why not directly use a forklift to unload the aircraft, one pallet at a time. Thanks in advance for the help.

Good day to you all, I would like to ask the forum for some technical help. I sale a product for cleaning landing gear struts call Strutwipe. It's a 100% lint free tightly woven cotton wipe that is saturated with either MIL-PRF-5606 or MIL-PRF-83282. When I worked for Lockheed back in the 90's, we would use 5606 for the struts. My question to the forum does the newer model C130 still use 5606 or have the struts been upgraded to 83282? Thanks for any help in advance. Best, Mark A&P and Owner of Strutwipe www.strutwipe.com

I have an old 501D13, (T56) built in 1954. We use it to pull air through a wind tunnel. I had to swap it out with an engine that was sitting in an engine can for 5 years. The new engine is giving me hot starts and high fuel flow at ground idle. I checked and rechecked the rigging. Swapped the TD valve and fuel control. This engine is unique, it does not have a TD amp, or TD control. Any ideas at what else I can look at or swap out to see if I can get this problem fixed? Its a difficult problem to diagnose because its run by a computer using a PLC.

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 …
