We can supply TSO'd senders for Mooney Aircraft - newer than L model. It would require a 337 for install. While we are an OEM systems for several manufacturers, we have been helping out the Bonanza / Baron, Cirrus and Cessna 177 crowd. We have a design for the Mooney late model aircraft. It is a powered sensor - but has been proven. At present the new Cirrus fleet (newer than 2012) has 300,000 hrs plus without a fuel sender replacement. Let us know. I believe we are competitive with rebuilt for a sender that plugs into the same location with a contactless technology.

Well - the world has changed. New fuel quantity systems have to meet a performance Standard the three newest for OEM aircraft (Cirrus G5, Cessna 172 thru Caravan, Piper M Series Update) are TSO'd designs (demonstrated standard of performance). As Vance indicated the FAA is concerned that the fuel quantity system provide accurate level information throughout the flight (Straight and level). They were very concerned with Cessna on the as early as the 1995 startup - Cessna calibrated each resistance sender to the aircraft. The largest change was to lightning and spark effects internal to the tank. Advisory Circular 23-17 SYSTEMS AND EQUIPMENT GUIDE FOR CERTIFICATION OF PART 23 AIRPLANES AND AIRSHIPS Digital fuel flowmeters are not a required powerplant instrument except for turbine engine airplanes with an Amendment 23-43 certification basis. They are optional equipment and should not be considered replacements for fuel quantity or fuel pressure indicators. In fact this is actually required for Australian aircraft every 4 years. It appears that the FAA is not on the same page as the rest of aviation .... However when you read the FSDO Documents, they paint an entirely different picture as does the Hazard Analysis of AC 23.1309 However they admit that bad information is no hazard - see image - I don't know if that holds water
