Abstract：By researching engineering application of helium leakage detection technology on a certain type wing
integral fuel tank leak detection to locate the leaking resource accurately and in advance, to remove the trouble preciously,
to avoid the hysteresis of problem finding caused by the delay of traditional airtight and oil tightness test procedure, and to
reduce rework and time cost, which has obvious benefits. The research result can be generated and applied in other sealing
components assembly test, and it is a beneficial exploration on application of digital detection technology in aircraft sealing
assembly as well.
