Airworthiness Directives; Bombardier Model DHC-8-200, and -300 Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Bombardier Model DHC-8-200, and -300 series airplanes. This action requires repetitive inspections to detect chafing or arcing damage to the cable/wire and fuel tube assemblies on the right hand side of each engine, and replacement with new components, if necessary. This action also provides an optional terminating action for the repetitive inspections required by this AD. This action is necessary to prevent chafing of the cable/wire bundles against the fuel line, which could result in arcing and a consequent fire or explosion. This action is intended to address the identified unsafe condition.
