Federal Aviation Administration September 28, 2018 – Federal Register Recent Federal Regulation Documents

The FAA is considering a proposal to change 97.507 acres of airport land from aeronautical use to non-aeronautical use and to authorize the sale of airport property located at Indianapolis International Airport, Indianapolis, Indiana. The aforementioned land is not needed for aeronautical use. The land consists of 155 original airport acquired parcels. The parcels were acquired under grants 6-18-0038-14, 3-18-0038-17, 3-18- 0038-18, 3-18-0038-23, 3-18-0038-24, 3-18-0038-43, 3-18-0038-45, 3-18- 0038-47, 3-18-0038-51, 3-18-0038-54, 3-18-0038-67, 3-18-0038-78, 3-18- 0038-81, 3-18-0038-83, 3-18-0038-88, 3-18-0038-96, 3-18-0038-112, Passenger Facility Charges, and local funding. There are no impacts to the airport by allowing the Indianapolis Airport Authority to dispose of the property. The land is not needed for future aeronautical development.

The Federal Aviation Administration (FAA) is hosting an industry day to introduce the Four-Dimensional Trajectory (4DT) Live Flight Demonstration Project to the aviation community. The FAA will present and discuss the 4DT Live Flight Demonstration Project vision, objectives, partnership requirements, and project timelines. The Industry Day will provide the initial platform for interested organizations to collaborate and strategize on project partnerships to execute the live flight demonstrations with the FAA.

We are superseding Airworthiness Directive (AD) 98-18-24, which applied to certain Airbus SAS Model A320 series airplanes. AD 98- 18-24 required repetitive inspections to detect cracking in the inner flange of a certain door frame, and corrective actions, if necessary. AD 98-18-24 also provided an optional terminating action for the repetitive inspections. This AD continues to require the repetitive inspections of the inner flange of a certain door frame, with reduced repetitive inspection intervals, and corrective action if necessary. This AD was prompted by a report of cracks on the inner flange of a certain door frame, and by the results of a full scale fatigue test that indicated the intervals for the repetitive inspections required by AD 98-18-24 must be reduced. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by reports of bushing migration and loss of nut torque on the engine pylon lower inboard and outboard link fittings. This AD requires modification of the attaching parts of the left-hand (LH) and right-hand (RH) pylon lower link fittings, inboard and outboard positions. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model 4101 airplanes. This AD was prompted by a report of an improperly installed spacer around the electrical pins in the cartridge connector for the fire bottle extinguisher cartridge. This AD requires repetitive inspections for excessive or missing spacers, and applicable corrective actions. We are issuing 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 727 airplanes. This proposed AD was prompted by a report of cracking in the inboard lower flange and adjacent web near the forward attachment of the outboard flap track at a certain position on a Model 737-300 airplane. The flap tracks of Model 737-300 airplanes are similar to the flap tracks of Model 727 airplanes. This proposed AD would require repetitive detailed inspections and surface high frequency eddy current (HFEC) inspections of each outboard flap track at certain positions for any crack and discrepancy, 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 all The Boeing Company Model 707, 720, and 720B series airplanes. This AD was prompted by a report indicating that a fracture of the midspar fitting resulted in the separation of the inboard strut and engine from the airplane, and a determination that existing inspections are not sufficient for timely detection of cracking. This AD requires repetitive inspections of certain nacelle strut spar and overwing fittings, and diagonal braces and associated fittings; replacement of the diagonal brace assembly on certain airplanes; and applicable related investigative and corrective actions. We are issuing this AD to address the unsafe condition on these products.
