Federal Aviation Administration November 26, 2018 – Federal Register Recent Federal Regulation Documents

The FAA is considering a proposal to change 131.227 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 131.227 acres is located along High School Road between Sam Jones Expressway to the south and the CSX railroad to the north. The land formerly served as parking areas for Indianapolis International Airport. The proposed use of the property is to be used for corporate development.

This action modifies Class E airspace extending up to 700 feet above the surface at Lac Qui Parle County Airport, Madison, MN, to accommodate new standard instrument approach procedures for instrument flight rules (IFR) operations at the airport. The FAA is taking this action due to the decommissioning of the Madison non-directional radio beacon (NDB) and cancellation of the associated approach. This enhances the safety and management of IFR operations at the airport.

This action establishes Class E surface airspace at Dothan Regional Airport, Dothan, AL. The Class E surface airspace is established for the safety of aircraft landing and departing the airport when the air traffic control tower is closed. Also, this action amends Class D airspace by updating the airport's name and geographic coordinates, as well as replacing the outdated term `Airport/Facility Directory' with `Chart Supplement'. Additionally, the geographic coordinates of the airport and Wiregrass VORTAC are adjusted in the associated Class E airspace to match the FAA's aeronautical database; as well as removing the part-time status of the airspace for Class E airspace designated as an extension to a Class D surface area. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.

We propose to adopt a new airworthiness directive (AD) for MDHI Model 369A, 369D, 369E, 369FF, 369H, 369HE, 369HM, 369HS, 500N, and 600N helicopters. This proposed AD would require inspecting each main rotor blade (MRB) for a crack. This proposed AD is prompted by reports of cracked MRBs. The actions of this proposed AD are intended to address an unsafe condition on these helicopters.

We are removing Airworthiness Directive (AD) 93-14-19, which applied to certain The Boeing Company Model 767-200 and -300 series airplanes. AD 93-14-19 required inspections for disbonding of the trailing edge wedge of the leading edge slat; and repair, if necessary. We issued AD 93-14-19 to prevent the loss of a trailing edge wedge, which could result in reduced maneuver margins, reduced speed margins to stall, and unexpected roll before stall warning, all of which would adversely affect the controllability of the airplane. Since we issued AD 93-14-19, an updated stability and control analysis showed that the worst-case scenario of a trailing edge wedge disbond in-flight would not adversely affect the controllability of the airplane. Accordingly, AD 93-14-19 is removed.
