What is the Take Off Weight of the O2?

[ConwayB]

Hello all,

I have purchased an O-2A and am getting it registered in Australia. Now, here's the problem...

When the new weight and balance was done, the maximum take off weight issued by the WB inspector is 4190 lbs!

The O-2A, according to the USAF O-2 manual, had a maximum take off weight of 4850lbs and a maximum landing weight of 4400 lbs. (The extra weight was in weapons which were jettisonable in an emergency).

The O-2A is equivalent to the 337B and later... and the civilian 337B flight manual (which I have to use as the official flight manual) says the following:

" Gross weight 4000 lbs and 4400 lbs" (but with no explanation of the two numbers) as shown in Performance specifications

"The cargo loading envelope allows loading up to 4400lbs."

So can someone please tell me where I can find the definitive answer on this issue so I can ensure my WB is correct? Is there an official Cessna document available?

Thanks in advance.
