Got a utility hydraulic system that shows normal level until the engines are running. The level comes down quite a bit, several inches. However, when the engines are shutdown and system is un pressurized, the fluid level comes back to the same as before. Where is the hydraulic fluid going? What is causing this drastic drop in hyd fluid level?

Nose Radome Anti-Ice
by Guest- 20 replies

Several years ago, I recall there was an Air Force TCTO that disabled the (hot) bleed air nose radome anti-icing on most of the USAF C-130s. Supposedly, the hot air system was causing delamination and/or deterioration of the fiberglass layers in the radomes, driving the radome reliability rate down to an unacceptable level. It seems the new radome that comes on the J-model does not have an anti-icing capability either. Any feedback from flight crews on icing conditions (?), or was it never really a problem to begin with.

Ballast Fuel

Brothers, I am putting together a NATOPS change to include an easy to understand definition of \"Ballast Fuel\". Our NATOPS does not mention it at all. This has been a source of much debate and a soure of confusion to trainees. I am a Little Rock trained FE and was trained on this. The new trainees are not being tought TOLD data the same. My understanding is to use the Fuel Management charts to find the required landing fuel in the wings for a specific cargo weight. Then to get your g load factor and max airspeed. Which is usually only a factor in the decent. I understand that this is usually only a consideration over approx. 30k cargo. Further, my unders…

Here at LRAFB it has become common pratice to remove both flap baffles and allow the aircraft to continue to fly if one or both flap baffles are found to have a rub or be cracked. I guess this does not change the aerodynamic properties of the aircraft with flaps extended or the performance data in any way since STAN/EVAL and maintenance say this is acceptable. This doesn\'t really seem right to me but I can\'t find a reference in any publication that says it can\'t fly in this configuration. I have looked in the flight manual, lockheed manuals, 27JG, and every other publication I could think of. Kind of seems like flying with a panel missing, does anyone have any refe…

Does anyone know of any C-130 that the CP Instrument Bus will operate off Main AC as well as Ess AC?

Can anybody help me with information on the LVDT? I am no even sure about the nomenclature. Linear Voltage Displacement Transducer. I understand it is mounted near or under the pedestal and converts movement of the PLA. Thanks!

Hello all, I\'m looking for a part number for cloth sleeving- I\'m referring to the covering used over wire bundles or harness to protect the wires. I have some plastic one\'s , but prefer the clothe. I think it has a better life span and is more flexible when used with test cables. any help would be appreciated. Thank you Jeremy

Got an interesting call the other day from Warner Robins concerning 64-14859. As most of us know this plane started out as a HC-130, then to a EC-130, and now it is a C-130E. The problem that Robins had was that the RH Horizontal Leading Edge had extra exterior plating on the L/E of the structure. I finally got them to send some pics and sure enough this exterior plating runs the full length of the L/E. They said this L/E is from a Talon. They didn\'t specify which MDS. I know it isn\'t from the Talon II, but what about the T1? They were telling me it is a Flare deflector?? I looked in both the 1C-130H-4 and 1C-130(M)H-4 and the part numbers cross reference each other. …

I\'m currently rebuilding a Herk in Yemen that has been grounded for 4 years. We are a few months away from flying but working with limited TO\'s and are stuck for some part numbers. Can anyone help with the part numbers for aft nacelle fairing or \'D\' panel anchor nuts, inbd & outbd and fuel tank indication boundary plug \'O rings\'. Also any part numbers for the old style dzus fastener type overwing filler caps would be much appreciated. The a/c is a basic late 80\'s H model MSN 4872. Many Thanks.

First off, GREAT SITE!!! Now for business... Are there any modifications or upgrades to the C-130E/H platform for the engines? Any engine that can be installed on the C-130 that goes beyond the capabilities the -15 engines currently provide? If there is no follow on engine is there an upgrade kit to the -15 that allow it to perform better, cheaper or higher reliability? The same question can be asked of the current propeller assembly and/or valve housing. I have heard that there is a \"Electronic\" Valve Housing that could replace the analog version currently in service. I am looking for similar updates/upgrades to the following systems: Air Conditionin…

With all 4 engines running(normal grd idle), the copilot did the normal cycling of the flight controls and notice a 300-400psi drop on the utility and booster rudder boost pressure gauges. The needle on both gauges dropped 300-400 psi, then both gauges needles started to flux up and down. It did this in high and low rudder boost. When he cycled the elevator and elevator only, the drop was the highest(300-400psi), but with cycling the aileron we only noticed a 100psi drop, but with the the needles still fluxing, but not nearly as much. Does anyone know of a limitation with a flux with those gauges? I have checked my books and maintenance and have come up with nothing.…

Have a -16 with an interesting problem during induction runs. During crossover checks it will go to lights out, but the light will stay out. No noticeable correction, but is 830 peak and corrected. Come back to F.I. and light is still out. Go to G.I. light is out. Reverse, you guessed it, still out. Will only come back on on downshift. Until again you go above crossover. All the rest of the TD checks are ok. The light will come on during overtemp protection check, and overtemp correction is provided...check good. Have not done any troubleshooting, or corrective action yet, as this was the induction run. I suppose it could be an amp problem, but I seem to recall…

I have an aircraft that starts to pull to the left as it goes past 60 knots. When airborne the problem gets worse. First thoughts are Rudder. The technicians claim that the entire assembly has been re-rigged but it seems as if the problem has gotten worse. The props have been checked closely, the synchrophaser and autopilot LRU\'s were completely removed/depowered, the nose gear has been checked. I am still convinced the Rudder system is defective..thoughts?

Question for Guard units out there. How many full time and part time ECM troops does your Avionics element have? We (189th at LR) are probably the last Guard unit in the 130 world to get ECM systems and are needing this info to take to higher HQ. We never go on the road so we have no contacts out there in the real world. Thought we would see what kind of response we could get here. Please send info to ronald.jackson at arlitt.ang. you know the rest. Any previous documentation you may have in establishing positions on the manning document would be appreciated. P.S. I am posting this for my boss. and his is the addy listed. Thanks, Bax

If an engine, in Low Speed Ground Idle, has the fire burning in the turbine area, how does that happen? It will start with low start TIT (750) and run in LSGI, but there is a fire in the turbine and the blades glow. The fuel nozzles were flow checked and they were good. If the engine is sped up to NGI, the fire goes out and when shifted down again, the fire stays out. I have never seen that before, and I don\'t really have an answer as to how it is happening. The only theory I can come up with is that, for some reason, the fire is not starting in one or more burner cans, so the fuel from that nozzle is making it back to the inlet guide vanes where it is igniting.…

Good day. We encountered a strange defect on the C130H during a recent ground run, after a left wing refit during a depot maintenance. #1 throttle crept slowly towards T/O after a couple of seconds when all throttles were set at 900degC. A thorough check has been carried out on the airframe to engine cable tension,rigging and signs of binding. The results come up to be good. There wasn\'t any sign of engine vibrations during the ground run. We had also replaced the engine control clutch at the \'horsecollar\', a FCU and a coordinator as a precautionary measure. However, the defect remained the same. Has anyone had any suggestions to this problems? Thanks and appreciate. :…

A question came in about why we chain the gear. We know what it says in the Flight Manuals, we have all been taught why we do it but is there anything written down officially or in tech form that says why we chain (or use tie down fitting) for a main gear malfunction.

I am looking for the part number of the rubber SEALS for the PRESSURE TEST ADAPTER KIT, RMT P/N: 884FY-23 manufactured by ROSEMOUNT. These seals (I think there are qty 2) inside the Pressure Test Adapter to separate the Static port 1, Static port 2 and Pressure port. This pressure test adapter kit is use for checking the Pitot/Static Tube of H2 aircraft model (I think 5070 and above series). I appreciate anyone using the similar set can help me with the part number and or which company where I can buy the spare. My test adapter kit is leaking. Thanks in advance.

On the H3s, they have encapsulated toilets. The 1C-130A-23CL-1 step 9 reads: 9. Remove right and left ramp hinge panels and belly band panel. (Required for aircraft with encapsulated toilet, only on wash prior to ISO.) Wasn\'t the purpose of this actually for planes with the Urinal Drain Tubes? I was thinking it should read \'Not required for...\'. I know it used to get nasty and corroded with the drain tubes in these areas. The way the book reads now, it would never get accomplished on aircraft with drain tubes.
