sale. This item was removed from an aircraft in an unknown condition. There are no guarantees as to the accuracy or serviceability of this item. Therefore it is priced accordingly and will sell to the highest buyer. If there was any damage or known discrepancies, they would be identified and described in the sale listing. See pictures for cracking of faceplate. All knobs rotate freely. Representations: This item is sold as is. Airworthiness, and applicability to a specific aircraft or it’s component, are the responsibility of the buyer. At the least this should be considered as a repairable core, but there is a chance there are zero defects and it is fully functional. I am legally unable to officially bench test this item and provide a serviceable tag. I can only go off of the information provided to me by the previous owner and the avionics technician that removed the item. Any and all known defects or any doubt as to the serviceability of the item, I would have stated them and have them apparent in the listing pictures, or I would not list the item and have properly disposed of it. I'm not trying to hide anything or take advantage of anyone. My intent is to provide serviceable used items at an extremely discounted price to the general aviation consumer. All of the used parts I have sold so far have gone for 40%-95% below retail prices. I have had zero complaints about my other listings, the function of sold equipment, serviceability of said items or issues with shipping. Warning to purchasers/recipients: The aircraft parts you are purchasing or receiving, unless stated otherwise on ad, may not be in compliance with applicable Federal Aviation Administration (FAA) requirements. You are solely responsible for bringing the aircraft into compliance with 14 CFR, or other applicable standards, by obtaining all necessary FAA inspections or modifications. Please ask your questions before purchasing. I try my best to present all items as accurately as possible. The buyer is to make the final determination of airworthiness and suitability of the item. Buyer is to verify the applicability and accuracy of the listed item as it pertains to the installation and assumes all liability if installed without being inspected first. Keep an eye out for future parts listing as I have an assortment of aircraft instruments and avionics that I'm going to be listing, mainly removed from Cessna and Beechcraft to include factory original parts and some other parts from EDO-AIRE, Narco, S-Tec, Bendix/King, Aspen, Electronics International, JPI and Garmin. Free local pickup. I try to process items for shipping immediately. I almost always ship items within 24 hours of receipt of payment. However, there is a very unlikely chance it could ship up to 5 days after receipt of payment.
