ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc., Model PA-34-220T airplanes. This 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 AD requires 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 AD to address the unsafe condition on these products. DATES: This AD is effective January 5, 2021. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of January 5, 2021.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain serial-numbered Piper Aircraft, Inc., Model PA-34-220T airplanes. The NPRM published in the Federal Register on July 28, 2020 (85 FR 45353). The NPRM was prompted by a report of damage to the rudder flight control cables and the EPS system wiring due to inadequate clearance from the EPS wiring harness. Use of the rudder flight control cable and the motion of the cable rubbing against the EPS wiring can wear through the rudder flight control cable insulation and cause an electrical path to ground. The flow of the electrical current can burn (arc) through the rudder flight control cable strands, eventually severing the rudder flight control cable. In the NPRM, the FAA proposed to require inspecting the rudder fligh…
