Integration of Powered-Lift: Pilot Certification and Operations; Miscellaneous Amendments Related to Rotorcraft and Airplanes
This action proposes a Special Federal Aviation Regulation for alternate eligibility requirements to safely certificate initial groups of powered-lift pilots, as well as determine which operating rules apply to powered-lift on a temporary basis to enable the FAA to gather additional information and determine the most appropriate permanent rulemaking path for these aircraft. Powered-lift will be type certificated as special class aircraft under the existing regulations. Currently, there is not an established path for civilian pilots to be certificated with a powered-lift category rating. The general and commercial operating regulations do not contemplate operation of powered-lift. In addition to proposed changes for powered-lift, this action also proposes changes that would affect practical tests in aircraft that require type ratings, including airplanes and helicopters, training center rotorcraft instructor eligibility, training, and testing requirements, and training center use of rotorcraft in flight instruction.
Airworthiness Directives; Rolls-Royce Deutschland Ltd. & Co. KG Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd. & Co. KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines. This proposed AD was prompted by reports of cracks on affected intermediate-pressure compressor (IPC) rotor shaft balance lands. This proposed AD would require repetitive on-wing or in-shop borescope inspections (BSIs) of the affected IPC rotor shaft balance land for cracks, replacement of any IPC rotor shaft if necessary, and would prohibit the installation of an affected IPC rotor shaft on any engine, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 engines. This proposed AD was prompted by reports of malformed scallop edge geometry and surface conditions at the front flange scallops of affected low-pressure compressor (LPC) booster rotors. This proposed AD would require repetitive fluorescent penetrant inspections (FPIs) of the front flange scallops of the LPC booster rotor for any cracks, replacement or repair of the LPC booster rotor if necessary and, as an optional terminating action to the repetitive FPIs, a visual inspection for malformed scallop edge geometry and malformed surface conditions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF6-80E1A2, CF6-80E1A3, CF6-80E1A4, and CF6-80E1A4/B model turbofan engines. The NPRM was prompted by a manufacturer investigation that revealed that certain compressor discharge pressure seals (CDP seals) and forward outer seals were manufactured from powder metal material suspected to contain iron inclusion. The NPRM proposed to require the replacement of the affected CDP seals and forward outer seals. Since issuance of the NPRM, the FAA has reviewed subsequent information received from the manufacturer and determined that the unsafe condition is not likely to exist or develop in other products of the same type design. Accordingly, the NPRM is withdrawn.
