Special Conditions: Pratt and Whitney Canada, PW210A; Flat 30-Second and 2-Minute One Engine Inoperative Rating

These special conditions are issued for the Pratt and Whitney Canada PW210A engine model. This engine will have a novel or unusual design feature--an additional one engine inoperative (OEI) rating that combines the 30-second and 2-minute OEI ratings into a single rating. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
