Federal Aviation Administration October 29, 2015 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; B-N Group Ltd. Airplanes
Document Number: 2015-27571
Type: Proposed Rule
Date: 2015-10-29
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for B-N Group Ltd. Models BN-2, BN-2A, BN-2A-2, BN-2A-3, BN-2A-6, BN-2A-8, BN- 2A-9, BN-2A-20, BN-2A-21, BN-2A-26, BN-2A-27, BN-2B-20, BN-2B-21, BN- 2B-26, BN-2B-27, BN2A MK. III, BN2A MK. III-2, and BN2A MK. III-3 airplanes that would supersede AD 2014-03-18. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as damage of the cable sliding end assembly and installation of the incorrect end fitting on engine control cable assemblies. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Honeywell International Inc. (Type Certificate Previously Held by AlliedSignal Inc., Garrett Turbine Engine Company) Turbofan Engines
Document Number: 2015-27555
Type: Proposed Rule
Date: 2015-10-29
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Honeywell International Inc. TFE731-4, -4R, -5AR, -5BR, and -5R turbofan engines. This proposed AD was prompted by a report of certain interstage turbine transition (ITT) ducts failing to meet containment capability requirements. This proposed AD would require replacing certain ITT ducts. We are proposing this AD to prevent failure of the ITT duct, which could lead to an uncontained part release, damage to the engine, and damage to the airplane.
Airworthiness Directives; GA 8 Airvan (Pty) Ltd Airplanes
Document Number: 2015-27438
Type: Rule
Date: 2015-10-29
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for GA 8 Airvan (Pty) Ltd Model GA8-TC320 airplanes. This AD revises AD 2015-06- 02 R1, which required inspection to detect and correct the omission of steel washers at each isolator mount location. This AD retains the actions of AD 2014-06-02 R1 but corrects the AD number in the parenthetical of the compliance time in paragraph (f)(1) of the AD. This AD was prompted by reports of missing required engine mount fire seal washers, which could reduce the engine retention capability in the event of a fire. We are issuing this AD to require actions to address the unsafe condition on these products.
