Proposed Amendment of Class E Airspace; Maryville, MO
This action proposes to amend Class E airspace at Maryville, MO. Decommissioning of the Emville non-directional beacon (NDB) at Northwest Missouri Regional Airport, Maryville, MO, has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at Northwest Missouri Regional Airport. The airport's geographic coordinates also would be adjusted.

The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.
Proposed Establishment of Class E Airspace; Pender, NE
This action proposes to establish Class E airspace at Pender, NE. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAP) at Pender Municipal Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.
Proposed Amendment of Class E Airspace; Leesville, LA
This action proposes to amend Class E airspace at Leesville, LA. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAP) at Leesville Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.
Proposed Amendment of Class E Airspace; Springhill, LA
This action proposes to amend Class E airspace at Springhill, LA. Decommissioning of the Springhill non-directional beacon (NDB) at Springhill Airport, Springhill, LA, has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at Springhill Airport. The geographic coordinates of the airport also would be amended.
Proposed Establishment of Class E Airspace; Freer, TX
This action proposes to establish Class E airspace at Freer, TX. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAP) at Seven C's Ranch Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400, -401, and -402 airplanes. This AD requires an inspection of a certain alternating current (AC) power wire bundle for damage, and repair if necessary. Additionally, this AD requires segregating the wire bundle into two wire bundles and installing Teflon tubing. This AD was prompted by multiple reports of the loss of certain AC systems caused by a burnt AC power wire bundle. We are issuing this AD to prevent the loss of ice protection systems for the angle of attack vanes, pitot probes, engine inlets, and windshields, and consequent loss of or misleading airspeed indication and increased workload for the flight crew, which could lead to loss of control of the airplane.
Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes
The FAA is correcting a Notice of Proposed Rulemaking (NPRM) that was published in the Federal Register. That NPRM applies to certain Pilatus Aircraft Ltd. Models PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/B-H2, PC- 6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C-H2, and PC-6/C1-H2 airplanes. The Docket Number in the heading, in the Supplementary Information section, and in the Part 39Airworthiness Directive section is incorrect. This document corrects that error. In all other respects, the original document remains the same.
Airworthiness Directives; Rolls-Royce plc (RR) RB211-535 Series Turbofan Engine
We are superseding an existing airworthiness directive (AD) for all RR RB211-535E4-37, -535E4-B-37, -535E4-B-75, and -535E4-C-37 turbofan engines. That AD currently requires performing initial and repetitive visual and fluorescent penetrant inspections (FPI) of the low-pressure (LP) turbine stage 1, 2, and 3 discs to detect cracks in the discs. This new AD continues to require those inspections and changes the definition of a shop visit to be less restrictive. This AD was prompted by our finding that the definition of shop visit in the existing AD was too restrictive. We are issuing this AD to revise the definition of shop visit and to detect cracks in the LP turbine stage 1, 2, and 3 discs, which could result in an uncontained release of LP turbine blades and damage to the airplane.
Airworthiness Directives; General Electric Company Turbofan Engines
We are superseding two existing airworthiness directives (ADs) for General Electric Company (GE) CF6-45 and CF6-50 series turbofan engines with certain low-pressure turbine (LPT) rotor stage 3 disks installed. The existing ADs currently require inspections of high- pressure turbine (HPT) and LPT rotors, engine checks, and vibration surveys. This new AD retains the requirements of the two ADs being superseded, adds an optional LPT rotor stage 3 disk removal after a failed HPT blade borescope inspection (BSI) or a failed engine core vibration survey, establishes a new lower life limit for the affected LPT rotor stage 3 disks, and requires removing these disks from service at times determined by a drawdown plan. This AD was prompted by the determination that a new lower life limit for the LPT rotor stage 3 disks is necessary. We are issuing this AD to prevent critical life- limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.
