Four Dornier 228s operated by the German Navy’s Marineflieger-geschwader 3 “Graf Zeppelin” on pollution-control and surveillance missions are being upgraded with new glass cockpits and composite propellers by Ruag Aerospace. The German Office of Defense Technology and Procurement signed the contract for the upgrade program in early August.
Graf Zeppelin flies the four Dornier 228 twin turboprops on pollution-control missions for the German Ministry of Transport, Building and Urban Affairs. Missions include surveillance over German coastal areas and pollution control. Two of the 228s are the -212(LM) version and are used to track oil slicks back to their origin, according to the German Navy.
The new glass cockpit consists of four Universal Avionics LCD panels, Rockwell Collins radios and equipment, as well as military navigation and communication systems including SAR-capable weather radar, ACAS II and HF V/UHF radios. The aircraft will also be upgraded with five-blade MT Propeller composite propeller systems, which weigh 77 pounds less than the original four-blade propellers.
Ruag Aerospace (Stand C620), based in Switzerland, holds the type and production certificates for the Dornier 228 and has relaunched the program as the 228 NG. India’s Hindustan Aeronautics manufactures structural components for the 228 NG program, having built 228s for the Indian market since 1988. Ruag plans to deliver the first 228 NG early next year.
