## Abstract

These special conditions are issued for Pratt and Whitney Canada (PWC) model PW210S engines. The engine model will have a novel or unusual design feature which is engine operation in auxiliary power unit (APU) mode. 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.
