Dear Mr. Nowak,
Your posting on www.hotjobs.com seeking an Avionics Technician was something I wanted to apply for today with earnestness. I answer all the requirements you have in your ad, and have enclosed my resume for your consideration.
I have over seven years of experience working as an Avionics Technician at Bombardier Aerospace in North Charleston, SC. In this time, I have gained considerable experience in the testing, analysis, and repair of all aircraft engines, equipment, and materials to include: radio, navigation, missile, and radar systems. I love what I do, and I work fast with a highly technical mind.
If you like what you hear about my career qualifications, I ask that you please consider me and contact me at (555)-555-5555 at your convenience. Thanks for reviewing my cover letter and enclosed resume, and I look forward to hearing from you as soon as possible.
