Airworthiness Directive · Amendment 39-14133 · Bombardier Model DHC-8-400 Series Airplanes
Bombardier Model DHC-8-400 Series Airplanes
Superseded. A later AD replaced this one: AD 2007-11-09. Comply with the one in force.
This AD applies to Bombardier Model DHC-8-400 series airplanes, certificated in any category; as identified in Bombardier Alert Service Bulletin A84-26-06, dated May 12, 2005.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This AD requires inspecting the electrical connectors of the fire extinguisher bottles for the forward and aft baggage compartments and for the auxiliary power unit and engine nacelles to determine if they are connected correctly; and doing related investigative and corrective actions, if necessary. This AD is prompted by reports of the electrical connectors for the fire bottles in the forward and aft baggage compartments being cross connected. We are issuing this AD to detect and correct cross connection of the fire extinguisher bottles, which could result in failure of the fire bottles to discharge and consequent inability to extinguish a fire in the affected areas.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 14 days after the effective date of this AD, inspect the electrical connectors of the fire extinguisher bottles for the forward and aft baggage compartments and for the auxiliary power unit and engine nacelles to determine if they are connected correctly; and, before further flight, do the related investigative and corrective actions, as applicable; by doing all of the applicable actions specified in the Accomplishment Instructions of Bombardier Alert Service Bulletin A84-26-06, dated May 12, 2005. Although the service bulletin referenced in this AD specifies to submit certain information to the manufacturer, this AD does not include that requirement.
