One thing to consider is if you've got real property (house) if you can get an equity line of credit easily, Finance the plane through that. Your interest will be deductible (mortgage interest). Second thing to consider unless your business is aviation related avoid making it known or running your plane, boat or other hobby through your biz directly as this is a flag for the IRS. If anything document your Biz usage and have your biz buy your fuel. You should avoid co-mingling expenses as this could get you in trouble.
This advise cost you nothing and as such is worth that much.
Read my post carefully, seems below post seems to disagree, I said unless you biz is aviation related " avoid making it known or running your plane, boat or other hobby through your biz directly". Means if you buy a plane through your biz and depreciate it and try and write it off you will most likely trough up a red flag. If you document well and can prove you use it primarily for biz you'll be in good shape.
But talk to your CPA or tax adviser.
