C-9B Air Condition system shutting down (RIGHT AIR PACK)
 

Hello everyone, we are having a problem with our right air pack on our C-9B aircraft. During climb out, the right A/C Pack is shutting completely off, as if a valve is closeing. This problem is only happening a few sec. after weight off wheels...It will continue to stay off for several min.. aprox. 10-15 min and then just kick back on. We have tested system on ground and cant duplicate any problems. What area/item should we focus on with this problem...Thank you for the input..
