Special Conditions: CFM International, LEAP-1A and -1C Engine Models; Incorporation of Woven Composite Fan Blades

Samenvatting

This action proposes special conditions for the CFM International (CFM), LEAP-1A and -1C engine models. These engines will have a novel or unusual design feature associated with the engine fan blades--new woven composite fan blades. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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.
