Use of Developer to detect engine leaks
Several maintenance organisations seem to be using NDT developer to detect leaks on engine pneumatic systems. Can anyone advise if this is allowed, by this I mean documented as permitted in any manufacturers publications. As this seems to be a really effective way of detecting leaks is there a proprietary product to do this.

air leaks
never done it my self, but remember a mate said to test or detect leaks on air ducts on engines is to rap aluminum foil around joints. then start up engine and leak will blow a hole thru the thin foil.
To use NDT developer chalk to detects leaks would be used to check for oil or fuel leaks from pipes joints.

It is 
Take a look at A320 (CFM) AMM TASK 36-11-41-400-041 (Installation of the Intermediate Pressure (IP) Bleed Check Valve) and search for "developer" (Material Nr. CP3010).

In my experience, alu foil works a treat. It's particularly helpful around cabin bleeds etc.. The other option we use is to apply Ardrox developer in the area and observe the flow pattern. This is generally more use though for leaks from burner seals etc..
