Airworthiness Directive · Amendment 39-12307 · Bombardier Model DHC-8-200 and -300 Series Airplanes
Bombardier Model DHC-8-200 and -300 Series Airplanes
Model DHC-8-201, -202, -301, -311, and -315 series airplanes having serial numbers from 100 through 552 inclusive, certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Bombardier Model DHC-8-200 and -300 series airplanes, that currently 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. That AD also provides for an optional terminating action for the repetitive inspections required by that AD. This amendment requires accomplishment of the previously optional terminating action. The actions specified by this AD are intended 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.
