FAA Approval

  • Davtron Inc has determined that installation of all Davtron products are considered minor according to (FAR) 21.93(a). All of our units are similar in design, with their electrical, mounting size, and weight being similar. Even though we consider installation of Davtron products to be minor, it is up to the installing mechanic to determine if the installation is minor or major. For a minor, a maintenance log book entry is all that is required. The FAA has determined that the installation of replacement clocks in non-transport category airplanes is considered to be minor, therefore only a maintenance log book entry is required referencing letter 100S-GA-10-53 from the FAA.

  • For a major installation on a non PMA approved airframe, a FAA 337 form should be filed with your local FSDO and a possible field approval done.

Davtron Model 803-14V Ut Lt Foot & Et Digital Clock 14V Lighting Voltmeter OAT F & C Temp. Probe Included

Everything working fine so far. Keep alive function is wired direct to battery (with a 1/4a fuse protection). Hopefully will keep accurate time. So far so good!

Weve been using these for years in our helicopters, and they are fantastic. They got rid of two things, the OAT gauge and the clock, but this has the bonus of being a system volt gauge as well. The clock has several timing features which is great also. This current purchase was to replace an original unit that finally started giving out, some segments werent showing up and some buttons werent functioning correctly.
