## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 92- 07-05, which applies to certain Raytheon Aircraft Company (Raytheon) 65, 90, 99, and 100 series airplanes. AD 92-07-05 currently requires you to inspect the rudder trim tab for proper moisture drainage provisions, and if the correct drainage provisions do not exist, prior to further flight, modify the rudder trim tab. Since we issued AD 92- 07-05, FAA has received and evaluated new service information that requires the actions of AD 92-07-05 for the added serial numbers LJ-1281 through LJ- 1732 for the Model C90A airplanes. Consequently, this proposed AD retains all the actions of AD 92-07-05 and adds serial numbers LJ-1281 through LJ-1732 for the Model C90A airplanes in the applicability section. We are issuing this proposed AD to prevent water accumulation in the rudder trim tab, which could result in a change in the mass properties and thus result in the lower flutter speed of the airplane. Airplane flutter could result in failure and loss of control of the airplane.
