Thank you for using JustAnswer.
I'm sorry to hear about your situation. Your claim could be against this employee and her employer, as she was acting in the course and scope of her employment at the time of her actions. This case against the employer is under a vicarious liability theory known as "respondeat superior", where the principal is responsible for the acts of the agent. It's clearly a case under negligence law, as she had a duty not to drive negligently around planes or other vehicles, breached that duty, and her actions caused you foreseeable damages. You can go after the direct damages (the cost to repair the plane, loss in any value, etc...) as well as foreseeable consequential damages (loss of income, or cost to rent a plane for the time being to continue your business).
That being said, you need to contact an attorney in your area that deals with negligence cases. Go to www.lawyers.com or www.legalmatch.com to find an attorney in your area. You should be able to find one that will give you a free initial consultation and better advise you of your rights, any problems with your case, likelihood of success, how courts are treating cases such as yours in your area, and what you should do next.
