Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Dornier Luftfahrt GMBH (Dornier) Models 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 airplanes that have electrical cabin/cockpit heater option P05 or option P09 installed. This proposed AD would require you to modify the cockpit and cabin auxiliary heating wiring. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this proposed AD are intended to correct problems with the current design of the heater wiring, which could result in failure of the auxiliary cabin heater. Such failure could lead to overheating and smoke in the cockpit.
