After reading the many opinions and comments on wing attach bolt/fitting maintenance, and the general lack of consensus thereof, I shared all the information with an A&P who carefully inspected my airplane's wing attach points and came up with the following: PROBLEM - Forney F-1 right wing upper forward attach fittings worn .004 to .005 inch, caused by improper torqueing of wing attach bolt. Movement is slight, but discernible. SOLUTION - Clean all parts, apply zinc chromate and torque wing attach bolt to 1100 - 1300 inch lbs. This should stop the movement. If no movement is detected, fly aircraft, checking for any movement before each flight (as you should anyway). If any subsequent movement is detected, replace the attach bolt and fittings in question. To me, this sounds like a logical and safe approach to stopping any further wear. If it doesn't work, then I'll replace the fittings (4 at $175 each, plus removing wing skin, old fittings and riveting in new ones, etc., $$$$). Am I on the right track here?
