Chad and i did a leak check on TM3 heat shield and window circuits.Both circuits are pumped easily down to the bottom leak rate and base pressure on the leak detector. There are two VCR caps on heat shield circuit. Chad sprayed helium on both of them   ( tested individually,2 seconds every time ) . There is no response on leakdetecor during 45 seconds waiting time. On window circuit there are 2 VCR joints. Chad sprayed helim on these joints(2seconds for each), and no response on leak detector. All joints  are double checked(sprayed twice on each of them). The result is they are leak tight.
