Airworthiness Directive · Amendment 39-14205 · AvCraft Dornier Model 328-300 Airplanes
AvCraft Dornier Model 328-300 Airplanes
Superseded. A later AD replaced this one: AD 2009-01-06. Comply with the one in force.
This AD applies to AvCraft Dornier Model 328-300 airplanes, certificated in any category, serial numbers 3105 through 3223 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain AvCraft Dornier Model 328-300 airplanes. This AD 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. This AD also requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new inspections of the fuel tank system. This AD is prompted by the results of fuel system reviews conducted by the airplane 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.
For airplanes without option 033F003 installed: Within 12 months after the effective date of this AD, 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 the effective date of this AD, 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 the effective date of this AD, 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. Thereafter, except as provided in paragraph (i) of this AD, no alternative inspection intervals may be approved for this fuel tank system.
Note 1: This may be done by inserting a copy of AvCraft TR ALD-028, dated October 15, 2003, in the AvCraft 328JET Airworthiness Limitations Document. When this TR has been included in general revisions of the AvCraft 328JET Airworthiness Limitations Document, the temporary revision no longer needs to be inserted into the revised Airworthiness Limitations document.
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.
