Federal Aviation Administration September 17, 2018 – Federal Register Recent Federal Regulation Documents

The FAA is issuing this notice to advise the public that the FAA has prepared and approved (August 31, 2018) a FONSI/ROD based on the Final EA for a Runway 14/32 Relocation/Extension and Associated Improvements Project at the Lake Elmo Airport. The Final EA was prepared in accordance with the National Environmental Policy Act (NEPA) of 1969, as amended, FAA Orders 1050.1F, ``Environmental Impacts: Policies and Procedures'' and 5050.4B, ``NEPA Implementing Instructions for Airport Actions''.

This action extends the Order Limiting Operations at John F. Kennedy International Airport (JFK) published on January 18, 2008, and most recently amended on June 21, 2016. The Order remains effective until October 24, 2020.

We propose to supersede Airworthiness Directive (AD) 2014-20- 04, which applies to all Airbus SAS Model A318 series airplanes; Airbus SAS Model A319 series airplanes; Airbus SAS Model A320-111, -211, -212, -214, -231, -232, and -233 airplanes; and Airbus SAS Model A321-111, - 112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2014-20-04 requires repetitive inspections for cracking of the four titanium angles between the belly fairing and the keel beam side panel, an inspection for cracking of the open holes if any cracking is found in the titanium angles, and repair or replacement if necessary. Since we issued AD 2014-20-04, we have determined that additional work is necessary for certain airplanes. This proposed AD would continue to require repetitive inspections for cracking of the four titanium angles between the belly fairing and the keel beam side panel, an inspection for cracking of the open holes if any cracking is found in the titanium angles, and repair or replacement if necessary. This proposed AD would also revise the applicability by adding Model A320-216 airplanes. This proposed AD would also require a detailed inspection for and replacement of certain rivets (including a rotating probe test for cracks in the open holes), and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.

We propose to supersede airworthiness directive (AD) 2015-20- 04, which applies to certain Pratt & Whitney Canada Corp. (P&WC) PT6B- 37A turboshaft engines. AD 2015-20-04 requires initial and repetitive inspections until replacement of the No. 10 bearing, and eventual replacement of the No. 9 bearing, both located in the engine reduction gearbox (RGB) assembly. Since we issued AD 2015-20-04, P&WC has determined that the repetitive inspection of the bearings has an associated risk of gearbox damage or contamination and that the bearing installation required by AD 2015-20-04 does not adequately address the issue of bearing axial movement. This proposed AD would require removal from service and replacement of the No. 9 and No. 10 position bearings. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by a report of cracks in the body station (STA) 303.9 frame web and doubler at fastener holes common to the stop fitting at stringer 16 left (S-16L). This proposed AD would require repetitive surface high frequency eddy current (HFEC) inspections for cracking of the STA 303.9 frame web and doubler at the stop fitting at S-16L, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This AD was prompted by a report of cracks, in various directions, in the lower portion of a main landing gear (MLG) piston. This AD requires a detailed visual inspection of the MLG, and replacement if necessary. We are issuing this AD to address the unsafe condition on these products.
