Vintage Airplane - Mar 1996 | Experimental Aircraft ...
David Cheek, of Newport News, VA noticed that the screw called out in the parts manual to secure the aileron push rod to the aileron, an NAS 205-19, has been super-seded by the AN509/MS24694 screw. That would be great, but the head di- ameter of this newer 100 countersunk machine screw is a bit small er than the old one by about 0.030".
