FAA TSO Letter of Approval

FAA Certification

When installed in accordance with this installation manual and the limitations, the installation of our TSO Approved models 452/454/455/551 and 553 is unlikely to have an appreciable effect on the weight, balance, structural strength, reliability, operational characteristics, or other characteristics affecting the airworthiness of the aircraft, and should therefore be eligible for installation as a minor alteration.

Please see the Instructions of continued Airworthiness for each model for limitations (available on downloads page). Most customers have been able to install these as Minor installation per AC 23.1309-IE and FAR 23.109. You must seek proper guidance prior to installation from you local FAA FISDO for clarification.

FAA Advisory Circular on CO

The above FAA circular provides information on the potential dangers of Carbon Monoxide contamination from faulty engine exhaust systems or cabin heaters of the exhaust gas heat exchange type. It also discusses means of detection and procedures to follow when contamination is suspected.

View our installation examples.

Because of their sensitive nature, all carbon monoxide (CO) detector sensors require replacement after a period of time to remain accurate. All Guardian Avionics / CO Guardian aviation CO detectors feature a self-test at power on for each flight. If the unit shows a failure of the CO sensor upon power up, you must send the unit to Guardian Avionics for replacement or overhaul. Depending on level of use, storage environment, and flight environment, most CO sensors have a usable life of 5-7 years. Though our units have a required Time Before Overhaul (TBO) of Seven (7) years from point of installation regardless of self-test results, we recommend sending in your unit for replacement / recalibration every 5 years during your annual maintenance inspection to assure safety and accuracy of your unit.

The procedure for recalibration is as follows:

• Remove component and note full model number and unit serial number.
• Apply for an RMA Number at: https://www.guardianavionics.com/rma-request or call 520-889-1177 (M-F, 8am to 5pm MST) - the RMA number will be emailed back to you.
• Order a recalibration or new replacement at https://www.guardianavionics.com/recalibration.
• Send unit in under RMA number to: Guardian Avionics, Attn: RMA #___, 1840 E Valencia Rd, Suite 216, Tucson, AZ 85756
• Once
  unit is received by Guardian Avionics, the recalibrated or replaced
  unit will be shipped within 3-5 business days unless specified. Core
  charge will be refunded.
• Upon receipt of the recalibrated/replaced unit, a fresh 1 year limited warranty applies and the unit has a fresh 7 year TBO.
