Helicopter wiring must be checked for damage, and some panels replaced

US aviation regulators are proposing new rules for all Leonardo S.p.A. Model AB139 and AW139 helicopters. This means operators will have to repeatedly inspect overhead panels for electrical cable interference and fix any damage.

This proposed rule addresses a specific safety issue: electrical cables rubbing against connectors in the overhead panel. If approved, it will force helicopter operators to perform regular checks and repairs, preventing potential electrical failures. This is a routine but critical safety update for a widely used helicopter model.
