I have a loan that is to provide funds for investment in air ambulance charter that is secured by a residence plus 110 acres which is a farm. The call-report code has this coded as a small-farm loan. Would this be reportable as a small-farm loan?

Your collateral is a farm but the purpose of the loan is non farm related. IMO its not reportable as a Small Farm loan.

Loans that are to farmers for "commerical and industrial purposes" aside from the farm would not be reported in line item 3, small farm loans, but item 1b specifically addresses "Loans secured by farmland" and it does not exclude loans for non-farm purposes. I would code it here on the call report which would then make it reportable as a small farm loan. (If it's under size of course).
