Airworthiness Directives; Eclipse Aviation Corporation Model EA500 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Eclipse Aviation Corporation (Eclipse) Model EA500 airplanes equipped with a Pratt and Whitney Canada, Corp. (PWC) PW610F-A engine. This AD requires you to incorporate operating limitations into Section 2, Limitations, of the airplane flight manual (AFM). This AD results from several incidents of engine surge. We are issuing this AD to prevent hard carbon buildup on the static vane, which could result in engine surges. Engine surges may result in a necessary reduction in thrust and decreased power for the affected engine. In some cases, this could result in flight and landing under single-engine conditions.
Special Conditions: General Electric Company GEnx-2B Model Turbofan Engines
This notice proposes special conditions for General Electric Company (GE) GEnx-2B67 and GEnx-2B69 model turbofan engines. The fan blades of these engines will have novel or unusual design features when compared to the state of technology envisioned in the part 33 airworthiness standards. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These special conditions contain the added safety standards the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards of 14 CFR part 33.
