Federal Aviation Administration November 8, 2012 – Federal Register Recent Federal Regulation Documents

Special Conditions: Turbomeca Ardiden 3K Turboshaft Engine
Document Number: 2012-25214
Type: Proposed Rule
Date: 2012-11-08
Agency: Federal Aviation Administration, Department of Transportation
This action proposes special conditions for the Turbomeca Ardiden 3K model engines. This engine model will have a novel or unusual design feature which is a 30-minute all engines operating (AEO) power rating for hovering at increased power (HIP). This rating is primarily intended for high-power hovering operations that are normal mission functions. 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 FAA considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
