Airworthiness Directive · Amendment 39-15785 · Dornier Model 328-300 Airplanes
Dornier Model 328-300 Airplanes
Superseded. A later AD replaced this one: AD 2009-01-06 R1. Comply with the one in force.
This AD applies to all 328 Support Services GmbH Dornier Model 328-300 airplanes, certificated in any category, serial numbers 3105 through 3223 inclusive.
The FAA is superseding an existing airworthiness directive (AD), which applies to all AvCraft Dornier Model 328-300 airplanes. That AD currently requires modifying the electrical wiring of the fuel pumps; installing insulation at the flow control and shut-off valves, and other components of the environmental control system; installing markings at fuel wiring harnesses; replacing the wiring harness of the auxiliary fuel system with a new wiring harness; and installing insulated couplings in the fuel system; as applicable. The existing AD also requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new inspections of the fuel tank system. This new AD replaces the flight-hour-based threshold for conducting certain initial inspections, with a calendar- based threshold. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Note 1: This AD requires revisions to certain operator maintenance documents to include inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (k) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.
For airplanes without option 033F003 installed: Within 12 months after September 6, 2005 (the effective date of AD 2005-15-16), do the actions in Table 1 of this AD in accordance with the Accomplishment Instructions of AvCraft Service Bulletin SB-328J-00-197, dated August 23, 2004.
| Do the following actions— | By accomplishing all the actions specified in— |
|---|---|
| (1) Modify the electrical wiring of the left-hand and right-hand fuel pumps | Paragraph 1.B(1) of the service bulletin. |
| (2) Install insulation at the left-hand and right-hand flow control and shut-off valves and other components of the environmental control system | Paragraph 1.B(2) of the service bulletin. |
| (3) Install markings at fuel wiring harnesses | Paragraph 1.B(3) of the service bulletin. |
For airplanes with option 033F003 installed: Within 12 months after September 6, 2005, do the actions in Table 2 of this AD in accordance with the Accomplishment Instructions of AvCraft Service Bulletin SB-328J-00-198, dated August 23, 2004.
| Do the following actions— | By accomplishing all the actions specified in— |
|---|---|
| (1) Modify the electrical wiring of the left-hand and right-hand fuel pumps | Paragraph 2.B(1) of the service bulletin. |
| (2) Replace the wiring harness of the auxiliary fuel system with a new wiring harness | Paragraph 2.B(2) of the service bulletin. |
| (3) Install markings at fuel wiring harnesses | Paragraph 2.B(3) of the service bulletin. |
| (4) Install insulated couplings in the fuel system | Paragraph 2.B(5) of the service bulletin. |
Within 12 months after September 6, 2005, revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate the information in AvCraft Temporary Revision (TR) ALD-028, dated October 15, 2003, into the AvCraft 328JET Airworthiness Limitations Document (ALD). Thereafter, except as provided by paragraph (k) of this AD, no alternative inspection intervals may be approved for this fuel tank system.
Note 2: This may be done by inserting a copy of AvCraft TR ALD-028, dated October 15, 2003, in the AvCraft 328JET ALD. When this TR has been included in general revisions of the AvCraft 328JET ALD, the TR no longer needs to be inserted into the revised Airworthiness Limitations document.
(i) For Sub-tasks 28-00-00-02 and 28-00-00-03 (“Detailed Inspection of Outer and Inner Fuel Tank Harness Internal”), as identified in AvCraft TR ALD-028, dated October 15, 2003; or Section G, “Fuel Tank System Limitations,” of the AvCraft Dornier 328JET ALD TM-ALD-010599-ALL, Revision 2, dated January 31, 2005, the initial compliance time is within 8 years after the effective date of this AD. Thereafter, except as provided by paragraph (k) of this AD, these tasks must be accomplished at the repetitive interval specified in Section G, “Fuel Tank System Limitations,” of the AvCraft Dornier 328JET ALD TM-ALD-010599-ALL, Revision 2, dated January 31, 2005.
After accomplishing the actions specified in paragraphs (f), (g), and (h), and the initial inspections in paragraph (i) of this AD, no alternative inspections, inspection intervals, or critical design configuration control limitations (CDCCLs) may be used unless the inspections, intervals, or CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (k) of this AD.
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.
