April 9, 2017 at 09:06 #7041 Roscoe RoschéKeymaster According to Figure 1 of the maintenance manual, wing skin is 0.020 2024-T3 Alclad.

My annual is coming up and I want to make sure it is done correctly. April 9, 2017 at 18:19 #7045 Roscoe RoschéKeymaster Doubtful you have cracked the skin, just the paint over it. So it is a standard paint repair. Sand, fill, prime and paint. Cheers Roscoe April 9, 2017 at 21:39 #7046 Timothy EngvalsonParticipant Thanks!
