| Cessna 172, 182, 206: DC Power Distribution System - Avionics Master Switch (Jan 2012) | This Special Airworthiness Information Bulletin (SAIB) informs registered owners and operators of
an airworthiness concern associated with the avionics master switch on Cessna Aircraft Company
(Cessna) Model 172R, 172S, 182T, T182T, 206H and T206H airplanes. There is a potential for an
accelerated rate of failure of the switch, which may result in the loss of avionics equipment on
Garmin G1000-equipped airplanes.
Although failure of the switch can result in loss of equipment, these airplanes are designed such that
avionics equipment necessary for the pilot to continue safe flight and landing are still maintained
through the aircraft’s electrical system.
At this time, this airworthiness concern is not considered an unsafe condition that would warrant an
airworthiness directive (AD) action under Title 14 of the Code of Federal Regulations (14 CFR part
39). |
