Federal Aviation Administration December 9, 2015 – Federal Register Recent Federal Regulation Documents

Special Conditions: Cirrus Aircraft Corporation, SF50; Auto Throttle
Document Number: 2015-31058
Type: Rule
Date: 2015-12-09
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Cirrus Aircraft Corporation Model SF50 airplane. This airplane will have a novel or unusual design feature(s) associated with installation of an Auto Throttle System. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These 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.

Airworthiness Directives; Agusta S.p.A. Helicopters
Document Number: 2015-30973
Type: Rule
Date: 2015-12-09
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109A and A109A II helicopters. This AD requires inspecting the slider assembly pitch control (slider) for play and replacing the slider if the play exceeds certain limits. This AD is prompted by a report of excessive slider play and wear that was detected during a scheduled inspection of a Model A109A II helicopter. These actions are intended to detect and prevent excessive wear and play on a slider, which could lead to loss of tail rotor pitch control and consequently loss of helicopter control.
Airworthiness Directives; Pratt & Whitney Division Turbofan Engines
Document Number: 2015-30948
Type: Proposed Rule
Date: 2015-12-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Division (PW) PW4000-94 inch and PW4000-100 inch model turbofan engines. This proposed AD was prompted by a report of a crack find in the high-pressure compressor (HPC) disk. This proposed AD would require performing an ultrasonic inspection (USI) or an eddy current inspection (ECI) of the HPC 10th stage disk. We are proposing this AD to prevent failure of the HPC 10th stage disk, an uncontained disk release, damage to the engine, and damage to the airplane.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
Document Number: 2015-30947
Type: Proposed Rule
Date: 2015-12-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211-22B and RB211-524 turbofan engines with low-pressure turbine (LPT) support roller bearing, part number (P/ N) LK30313 or P/N UL29651, installed. This proposed AD was prompted by a report of a breach of the turbine casing and release of engine debris. This proposed AD would require removal of certain LPT support roller bearings installed in RR RB211-22B and RB211-524 engines. We are proposing this AD to prevent failure of the LPT support roller bearing, loss of radial position following LPT blade failure, uncontained part release, damage to the engine, and damage to the airplane.
Airworthiness Directives; Piper Aircraft, Inc. Airplanes
Document Number: 2015-30882
Type: Proposed Rule
Date: 2015-12-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 96-12-12, which applies to certain Piper Aircraft, Inc. Models PA-31, PA-31-300, PA-31-325, and PA-31-350 airplanes. AD 96-12-12 currently requires a one-time inspection of the bulkhead assembly at fuselage station (FS) 317.75 for cracks and the installation of one of two reinforcement kits determined by whether cracks were found during the inspection. Since we issued AD 96-12-12, bulkhead cracks were found on airplanes that had complied with AD 96-12-12 and on additional airplanes not affected by AD 96-12-12. This proposed AD would require repetitive inspections of the bulkhead assembly at FS 317.75 for cracks, repair of cracks as necessary, and the installation of a reinforcement modification. We are proposing this AD to correct the unsafe condition on these products.
