Special Conditions: Pratt and Whitney Canada Model PT6C-67E Turboshaft Engine

These special conditions are issued for Pratt and Whitney Canada (PWC) model PT6C-67E engines. The engine model will have a novel or unusual design feature which is a 30-Minute All Engines Operating (AEO) power rating. This rating is primarily intended for high power hovering operations during search and rescue missions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the added safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
