## Abstract

These special conditions are issued for the Soloy Corporation, Soloy Dual Pac engine (formally Soloy Dual Pac Inc.). This engine will have a novel design feature associated with its configuration. The Soloy Dual Pac engine is a propulsion system in which two Pratt & Whitney Canada (PWC) Model PT6 turbine engines are combined through a common gearbox to drive a single output propeller shaft. The Soloy Dual Pac engine is intended to provide a degree of continuous operation following the failure of one of the PWC Model PT6 engines. The applicable regulations do not contain adequate or appropriate safety standards for such a configuration. These special conditions contain the additional safety standards which the Administrator considers necessary to establish a level of safety equivalent to that established by the airworthiness standards of part 33 of the Federal Aviation Regulations (FAR).
