Write a good cover letter that says you will wash aircraft, sweep hangar floors, run parts, help the mechanics, drive trucks, organize trailers, paint walls, hang dry wall, clean toilets, take the thrash out, answer phones whatever is needed to help the company operate and achieve your dream at the same time of becoming a professional pilot.
