## Summary

We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation F33 Series and Models G33, V35B, A36, A36TC, B36TC, 95-B55, D55, E55, A56TC, 58, and G58 airplanes and Raytheon Aircraft Company Models 58P, 58TC, and 77 airplanes. This proposed AD would require you to replace certain circuit breaker toggle switches with improved design circuit breaker toggle switches. This proposed AD results from reports of certain circuit breaker toggle switches used in various electrical systems throughout the affected airplanes overheating. We are proposing this AD to prevent failure of the circuit breaker toggle switch, which could result in smoke in the cockpit and the inability to turn off the switch.
