For installing the intersection fairing, do you need to jack up the plane off its gear? Page 46A-26 step 2 says ?The aircraft can now be returned to the ground and the jacks removed? but at no point prior other than for the nose wheel they ask you to jack up the plane. I don't have my engine, wings and tail portion mounted and I am wondering how much of a deflection I get with the gear if it is not jacked up.
