2014-11-04; vol. 79 # 213 - Tuesday, November 4, 2014 79 FR 65508 - Airplane and Engine Certification Requirements in Supercooled Large Drop, Mixed Phase, and Ice Crystal Icing Conditions
GPO FDSys XML | Text Additional Documents DEPARTMENT OF TRANSPORTATION, Federal Aviation Administration Final rule. Effective January 5, 2015. 14 CFR Parts 25 and 33 Summary The Federal Aviation Administration is amending the airworthiness standards applicable to certain transport category airplanes certified for flight in icing conditions and the icing airworthiness standards applicable to certain aircraft engines. The regulations will improve safety by addressing supercooled large drop icing conditions for transport category airplanes most affected by these icing conditions; mixed phase and ice crystal conditions for all transport category airplanes; and supercooled large drop, mixed phase, and ice crystal icing conditions for all turbojet, turbofan, and turboprop engines.
2014-10-31; vol. 79 # 211 - Friday, October 31, 2014 79 FR 64666 - Special Conditions: SNECMA, Silvercrest-2 SC-2D; Rated 10-Minute One Engine Inoperative Takeoff Thrust at High Ambient Temperature
GPO FDSys XML | Text Additional Documents DEPARTMENT OF TRANSPORTATION, Federal Aviation Administration Final special conditions. The effective date of these special conditions is December 1, 2014. 14 CFR Part 33 Summary These final special conditions are issued for the SNECMA, Silvercrest-2 SC-2D engine model. This engine will have a novel or unusual design feature—an additional takeoff rating that increases the exhaust gas temperature (EGT) limit to maintain takeoff thrust in certain high ambient temperature conditions with one engine inoperative (OEI) for a maximum of 10 minutes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These final 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.
