Deducting Aircraft Expenses - Standard Mileage Deduction?

I use a pennies per hour rate. There is a Governement website
(http://www.gsa.gov/Portal/gsa/ep/con...asic.jsp&P=MTT)
that has a per mile rate ($1.07) for reimbursement for privately owned
aircraft. I convert that into $/hr. based on the performance of my
aircraft.

I feel that this is a pretty solid figure since it is published by the
governement and appears on the same page as the accepted $ .305 per
mile for cars. Though it does not really tract actual expenses
incurred. For example, if you had a single and a twin both with the
same cruise performance they would come out to the same reimbursement
number but we all know the running expenses of the twin would actually
be higher.

Well, don't forget that the page you reference has nothing to do with the
IRS. It is merely what the GSA chooses to give its employees. There's no
guarantee that the IRS will accept those numbers, although they might.

OTOH, there is a history of the IRS accepting actual expenses (including
depreciation).

When I was using my Mooney for business purposes, I would always come out
ahead using actual costs rather than whatever the GSA was allowing its
employees in any particular year.

Looking at last years numbers, I would still come out ahead using actual
numbers vs the GSA employee reimbursement rate.

It's likely the Sundowner is less expensive to maintain than my Mooney, but
if the OP has recently purchased it, he may have a significant depreciation
deduction that he is giving up. In addition, if he has a major a/c related
expense, he might be able to benefit significantly from the actual cost
method. An engine or new avionics can be depreciated; a paint job can (or
at least could in the past) be written off entirely in the year it was
done.

There also may (or may not) be issues with whether or not he is above or
below 50% business use threshold; and I seem to recall that once you choose
to use the standard mileage rate (for autos), that you have to stick with
it.

Probably his best bet would be to not fear the record keeping requirements,
and also to check with folk knowledgeable about writing off a/c usage.
