Aircraft Clearance / Qualification for Paradropping

[stressmerchant]

I'm looking for some pointers on formal standards for the qualification / clearance of aircraft for parachute operations. The various standards on parachuting (eg FAR 105) do not have much guidance on assessing the suitability of the aircraft for release of parachutists, particularly using static lines.

I have found some reports done on the C-27J and A400M designs, which seem to suggest that paratroopers are assessed in much the same way as stores - flow fields, release paths and so on. (Gives new perspective on the phrase "meatbombs"). But these reports do not seem to have any formal criteria for the assessment, eg assumed body position of jumper, minimum allowable distance between canopy and aircraft during opening.

Is there a formal standard for qualification of aircraft for paradropping?

Thanks
