Airworthiness Directives; 328 Support Services GmbH (Dornier) Model 328-100 Airplanes

What this AD requires

The FAA is revising an existing airworthiness directive (AD), which applies to all 328 Support Services GmbH (Dornier) Model 328-100 airplanes. That AD currently requires modifying the electrical wiring of the fuel pumps; installing insulation at the hand flow control and shut-off valves, and other components of the environmental control system; and installing markings at fuel wiring harnesses. That 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 clarifies the intended effect of the AD on spare and on-airplane fuel tank system components. 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.

Applies to all Model 328-100 airplanes, certificated in any category (fuel tank system design review AD).

Whether AD E9-28299 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD E9-28299 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
