Airworthiness Directives; Gulfstream Model G-V Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Gulfstream Model G-V series airplanes. This action requires performing a one-time general visual inspection of the pilot's overhead circuit breaker panel wiring for discrepancies; rerouting the P45-12 wire; and repair, if necessary. This action is necessary to prevent circuit breaker wiring from becoming pinched or damaged, causing arcing between the wire and attaching bracket, which could result in smoke and/or fire in the pilot's circuit breaker panel. This action is intended to address the identified unsafe condition.
