## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Aerostar Aircraft Corporation Model PA-60-601P (Aerostar 601P), PA-60-602P (Aerostar 602P), and PA-60-700P (Aerostar 700P) airplanes. This proposed AD was prompted by reports of corrosion on the elevator and aileron balance tubes. This proposed AD would require repetitively inspecting the elevator and aileron balance tubes for corrosion and rust and replacing the tube. The FAA is issuing this proposed AD to address the unsafe condition on these products.
