An Airworthiness Directive (AD) that affects Diamond Aircraft Industries models DA40, DA40-D, DA40-F and DA40-NG was issued last week. The AD addresses the potential for deterioration of the fuel tank hose connection. Rubber parts from the hoses have been found in the fuel tank and gascolator according to reports.
The action required by the AD is to replace existing parts (according to a list found in the AD) with replacement parts supplied by the manufacturer.
Complete details can be found in the appended AD below.
