Cessna 172N-FUEL TANK DIMENSIONS
 

Anyone able to give me the dimensions of a C172 N wing tank,and also wing dihedral.I realise it probably has a curved top surface,but best figures would be appreciated,as I don`t have access to one at home..MANY THANKS..

ON THE TOP OF THE WINGS THERE IS A REMOVABLE SKIN.THE TANK HAS THE SAME SIZE + OR _ A COUPLE OF INCHES...i JUST REMOVED THESE SKINS FEW DAYS AGO TO CHANGE THE SEALS UNDERNEATH

HOPE THIS HELPS

Why
 

Why do you need to know the dihedral.
This is set up with wash out during wing build or rebuild on a jig.
If I remember correctly (its be over 25years that I last rebuild a 172 wing ) the dihedral and wash out starts outboard of the wing strut. The info should be either in the SRM or Flight manual . Not sure now its be to long. The only adjust you have is at the rear wing to fuse attachment bush .
With regards to your fuel tanks, why do you want the size, If the P/no is not correct, its the wrong tank !

Washout is 3 degrees 0 minutes measured outboard of the strut

Standard tanks or long range?
