## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Raytheon Aircraft Company (Raytheon) Model 390 airplanes. This proposed AD would require you to replace the rudder pedal arm assemblies used in the rudder control system with parts of improved design. This proposed AD results from reports of cracks found on the rudder pedal arm assemblies. We are issuing this proposed AD to prevent failure of the rudder pedal arm assemblies caused by fatigue cracks. This failure could lead to loss of rudder control, loss of nose gear steering, and loss of toe brakes on the side on which the failure occurs.
