Davtron Inc. recommends that you purchase our products through your local avionics shop and have them do your installation. They know how to handle all the log book entries you need for FAA approval. If your airframe is not listed on our PMA approval list above for the unit you're installing, you need to complete a FAA 337 form and file with your local FSDO. FAA PMA # PQ1062NM.
