## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Model PA-34-220T airplanes. This proposed AD was prompted by a report of damage to the rudder flight control cables and the emergency power supply (EPS) system wiring due to inadequate clearance from the EPS wiring harness. This proposed AD would require inspecting the rudder flight control cables and the EPS wiring for damage, replacing damaged cables and wires if necessary, and re-routing the EPS wiring harness to ensure proper clearance between the EPS and the rudder flight control cables. The FAA is issuing this proposed AD to address the unsafe condition on these products.
