I was also surprised at the relative lack of response to the
NPRM when it was first issued last year... I'm a bit surprised as well. I rather wonder if the wording of the thing might have something to do with it: "Replace the spar spigots? How hard can that be. I'll order them, they'll come in a box. I'll have my A&P unscrew the old ones, screw in the new ones, and be on my way!" In actuality, if the 102 is anything like the 103, replacing the spigots is fairly major surgery requiring special tools and techniques. It involves cutting away some relatively massive chunks of fiberglass at the end of the spar stub and digging out the steel pin and its attachment to the plywood shear web reinforcement. Then you can replace that portion of shear web, use a special fixture to locate and install the new steel pin and its mounting flange, and apply about 8 layers of bias fiberglass over the whole spar end. Thanks, Bob K. |
