Federal Aviation Administration October 21, 2016 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Piper Aircraft, Inc. Airplanes
Document Number: 2016-24857
Type: Proposed Rule
Date: 2016-10-21
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 95-26-13, which applies to certain Piper Aircraft, Inc. Models PA-28-140, PA-28- 150, PA-28-151, PA-28-161, PA-28-160, PA-28-180, PA-28-181, PA-28-235, PA-28-236, PA-28R-180, PA-28R-200, PA-28R-201, PA-28S-160, PA-28S-180, PA-32-260, PA-32-300, PA-32-301, PA-32-301T, PA-32R-300, PA-32R-301 (SP), PA-32R-301 (HP), PA-32R-301T, PA-32RT-300, PA-32RT-300T, and PA- 32S-300 airplanes equipped with oil cooler hose assemblies that do not meet certain technical standard order (TSO) requirements. AD 95-26-13 requires inspections, replacement, and adjustment of the oil cooler hose assemblies, as well as providing for a terminating action. Since we issued AD 95-26-13, the FAA has received requests to clarify the intent of AD 95-26-13. This proposed AD would maintain all of the actions required by AD 95-26-13 and add language to clarify those requirements. We are proposing this AD to prevent rupture or failure of the oil cooler hose assemblies, which could result in engine stoppage with consequent loss of control.
Airworthiness Directives; Airbus Airplanes
Document Number: 2016-23787
Type: Proposed Rule
Date: 2016-10-21
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This action revises the notice of proposed rulemaking (NPRM) by requiring an additional action for sealant application on some nuts and bolts on the National Advisory Committee for Aeronautics (NACA) duct assembly and adding a grace period to the compliance time. We are proposing this SNPRM to detect and correct corroded circlips. Such corrosion could lead to failure of the circlips and consequent movement of the FVP and result in a reduction of the flame protector capability of the FVP cartridge. Such a condition could result in damage to the airplane in case of lightning impact or fire on the ground. Since the additional actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
