## Summary

We propose to supersede an existing airworthiness directive (AD) that applies to all CPAC, Inc. (type certificate formerly held by Commander Aircraft Corporation, Gulfstream Aerospace Corporation, and Rockwell International) Models 112, 112B, 112TC, 112TCA, 114, 114A, 114B, and 114TC airplanes. The existing AD currently requires a one- time inspection of the elevator spar for cracks and, if any crack is found, either replace with a serviceable elevator spar that is found free of cracks or repair/modify the elevator spar with an FAA-approved method. That AD also requires reporting to the FAA the results of the inspection. Since we issued that AD, using the data collected through the reporting requirement, we have determined there is a need for continued inspections. This proposed AD would require repetitive inspections of the elevator spar for cracks and, if any crack is found, either replace with a serviceable elevator spar that is free of any cracks and/or corrosion or repair/modify the elevator spar with an FAA- approved procedure. We are proposing this AD to correct the unsafe condition on these products.
