Whether the helicopter or the aerotransport, NDT methods are used in the development phasemanufacture phase use phase and
maintenance phase .Especially penetrant testing is the efficient measure. We confirm the parts which do the penetrant testing
a
ccording to the load in the development phase; Have penetrant testing after the working procedure which produce the defects in
ma
nufacture phase; Have penetrant testing for the area which use the big load in use phase. We must ensure the validity of penetrant
te
sting in every phase. The arrangement of penetrant procedure ,surface prepare of machine parts ,protection of on-working parts,
th
ese are all the problems in the practice working. We analysis and innovate these problems, halve the experience with the other
NDT technicians.
