we are using turbine refrigeration unit P/N:203720-1 for C-130 B ac.The consumption rate is very high. How can we recover the problem......? We have the ac ser no:  3553, 3676, 3589 & 3647. Can we use some other models of turbine refrigeration unit in our aircraft....?

This is correct and current.  In addition, see more detailed brochures attached.    We keep these turbines and heat exchangers in stock most of the time, and yes, they replace 203720 and 203430 series turbines, regardless of Aircraft Serial number.  

Also attached E2H ECS upgrade information, which is a more extensive retrofit up to a C-130H ECS System.  More reliable, 230% more air flow, better pressurization, but also more expensive.

Many System Upgrades and Modernizations available, from starters to, bleed ducts, ECS systems to refurbishing the Center Wing Boxes, GTC to APU upgrade (see attached).  We have a long list of supportable system modernizations I can discuss in detail. 

C-130 SHORT-POD(TM) APU Upgrade Kit Presentation-Final-August212015.pdf

Use the latest Honeywell part number 203720-3-2, which are modified with ceramic bearings and the oil system is converted from dry sump to wet sump, with a dipstick for checking service level.   This change requires no modifications.

Alternatively, if you really want to improve the performance and reliability, go with a system upgrade such as E2H(TM) ECS. 

For the flight deck, the newest turbine part number is 203430-4-1.  Same improvements as described above for 203720.  Also consider the heat exchanger from aluminum to Stainless Steel.

Munir, the Bendix are now Honeywell PN 28B58-9B.  Reason for failure (burning) can only be determined after a shop teardown, but if oil splashing was abundant enough, probably shorted components internally.   Im available at [email protected]. 

As each MLG Ballscrew is approved by part number, ensure that the alternative you are installing are listed in the AC IPC.  Once this is confirmed, I agree with Mr. Myers, there is no other requirement to match part numbers.  

Dear Mr. Munir,

First concern is oil splashing on the generator! from what source?  This is not normal and must be fixed before running engine or installing replacement generator.   Potential fire hazzard.  We represent the manufacturer of the generator you mention.  We can perform a teardown and report exact cause of failures.  Also we can offer alternative gen in NEW condition with 3 yr warranty, as a more readily available modernization. Lastly,  we have RRC with PAF.  Regards. 

Don't have the fleet info, but CAF recently started upgrading 4 remaining E model GTC with Short-Pod APU from Kellstrom. Reportedly to be used for SAR missions.

Do you have a part number?
