Hello expertise 

During ISO inspection, it was observed  main landing gear down limit SWs are body badly damage due rubbing/chaffing of landing carriage .   The gap is within limit on ground  ops of landing gear. The chaffing signs were monitored on AUX jack pad on few aircraft.

 Hello expertise ,Caution: Ensure that the underfloor heating and fan switches are in the OFF position during engine starting and switching of generator loads from one to another.Failure to comply could result in a burned−out generator control panel. HOW ?  if so Which part of control panel will  burnt out explain

Hello expertise reply

In-flight  ,APU generator can energise the main AC bus if all engine generator are failed if not why? 40 kva generator capable to hot two AC buses

NATOP1 agree but how it  can smooth cut off the fuel during defueling operation. instead of butterfly it canbe  designed shutter valve.

thanks

what is purpose of fuel offload valve . How it smooth cutoff duing offloading of fuel  with dump pump.

I can only see it as a hardware issue. Is this only on one engine generator? Maybe it is excess vibration. I have no information on the hardware installation. That is in T.O. 8A6-9-5-3.

Tinyclark can you send copy of T.O. 8A6-9-5-3.

With  4 eng low when feathering pump on for feathering the prop on ground check atm generator light goes on. We changed the atm gen and atm but prob remain same.............need ur suggestion please.

Normally it happened due ATM regulating  valve assembly. please cannibalize to other

Are you saying the generator came loose from the gearbox, or did the generator come apart?  Three times?

Excitation generator mounting screws (housing Screws) has  broken from their  main generator stator  housing. cause could be vibration of  generator shaft

Aux motor relay contacts are pitted. open the relay contacts see the condition.

Tinyclark do you have color internal diagram of GPP. if , please sent.

where is oil leaving engine: turbine, #3 bearing lab seal vents, #2 bearing vents, 5th & 10th stage bleed valves wet, during climb or descent, level flight (altitude)? need a lot more information

ADH vent

hello expertise

Engine oil suddenly loss during flight defect could repeat on ground operation

munir abbasi

Hello C-130 expertise tiny clark/NATOPS 1

Almost three time happened excitation generator detached ( separate) from its mounting during operation of aircraft engine. its mounting screws thread washout. screws came out  along locking. please give me expert opinion

munir abbasi

Thanks Mr Bogi252

Oil source is engine RGB generator spline. regarding generator offering, q? free of cast for marketing. lockheed marten only recommend bendex or leyland specification. i need  reason for generator burning

What model?  

Sounds like you are having multiple engine generators failing? In flight, on ground, same engine?  Give some details please.

Just want to clarify your issue before I throw out ideas

c-130 E model brushless leyland generator  (CIP) VR GE . this happened when just landed and  PL did reversing procedure

engine oil splash around the generator body. disassemble found diode output contact burnout. it happened several engine generator with same fashion.

Hello C-130  expertise

AC engine generator (leland) exciter (rotor) burn out (defect trend ),reason could not find out. expert opinion is required.

switches with this type lines are called harmatically sealed switches so they can be used in emergency even in presence of fumes. normal switches can give spark that can ignite the fumes.

See above picture

too much risk 

munir abbasi

it seem to manifold  or restrictor defective if aux pressure is indicated normal on gauge
