It looks to be about 1/4" movement with concave being the predominant state. Is this acceptable? If not what is the remedy? It is the same bay as the access panel so I can get behind the skin. TIA - Pete Pete, I seem to remember this coming up before so you may wish to check the archives. I think the solution suggested was to use a length of stiffener prosealed to the inside of the offending skin to correct its shape. You would need to make sure you get the prosealed stiffener wedged in place for several days. Clean with MEK or similar. Good luck. Rob Rob W M Shipley N919RV (res) Fuselage .....still!
