First part is 100%, getting a different part on the second run is 100%-38.72%=61.28% (In the worse case he didn't get the Systems first). Getting the rarest part, the systems, in the third run is a 22.56% chance. Thus getting everything in 3 runs is at worst 100%*61.28%*22.56%=13.82% chance, so rather "fairly  lucky".
