Airworthiness Directive · Amendment 39-14140 · Avcraft Dornier Model 328-100 and -300 Airplanes
Avcraft Dornier Model 328-100 and -300 Airplanes
This AD applies to AvCraft Dornier Model 328-100 series airplanes having serial numbers 3005 through 3119 inclusive, and AvCraft Dornier Model 328-300 series airplanes without option 033F003 “Extended Range” installed; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Avcraft Dornier Model 328-100 and -300 airplanes. This AD requires a pressure test and detailed inspection of each fuselage drain line to determine if there is a blockage, and related investigative/ corrective actions if necessary. This AD is prompted by a report of leakage at one of the drain lines in the fuselage. We are issuing this AD to prevent blockage within the drain lines, causing fluids to collect. These fluids may freeze and expand, damaging the drain lines, and allowing fuel to leak into the cabin and fuel vapors to come into contact with ignition sources, which could result in consequent fire in the cabin.
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 4 months after the effective date of this AD: Perform an initial pressure test and any applicable related investigative and corrective actions in accordance with the Accomplishment Instructions of Avcraft Service Bulletin SB-328-53-462, Revision 1, dated July 15, 2004 (for Model 328-100 series airplanes); or SB-328J-53-214, Revision 1, dated July 15, 2004 (for Model 328-300 series airplanes); as applicable. Do any applicable related investigative or corrective action before further flight.
After doing the pressure test required by paragraph (f) of this AD, but not later than 24 months after the effective date of this AD: Perform a detailed inspection and related investigative and corrective actions, in accordance with Part 2 of the Accomplishment Instructions of Avcraft Service Bulletin SB-328-53-462, Revision 1, dated July 15, 2004; or SB-328J-53-214, Revision 1, dated July 15, 2004; as applicable.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
