. If the FAA find you are acting as PIC and flying an airplane without a valid airworthy certificate, you will be in for more that just finacial problems. If the pilot/builder changes/ modifies something in his plane that the feds require paperwork approval or recertification for, THEY BETTER DO IT. Otherwise the airplane is not airworthy. To fly and unairworthy airplane (by FAA standards) will result the revoking of your pilots ticket and perhaps other pentalies.
