Federal Aviation Administration June 19, 2019 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737 series airplanes, except for Model 737-100, 200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of separation of the lower aft wing-to-body fairing panel 194E (``fairing panel 194E'') during flight, due to worn or damaged nutplates on the support structure. This proposed AD would require repetitive inspections of fairing panel 194E, wheel well panel 193D, and support structure for discrepancies, and related investigative and corrective actions if necessary. This proposed AD would also require rework of the panels and support structure, which would terminate the repetitive inspections. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to modify Class D airspace at Acadiana Regional Airport, New Iberia, LA. The FAA is proposing this action as the result of the decommissioning of the ACADI non-directional radio beacon, (NDB). This would enhance the safety and management of standard instrument approach procedure for instrument flight rules (IFR), operations at this airport.

This action proposes to establish Class E airspace extending upward from 700 feet above the surface at Hunt Field, Lander, WY, to accommodate new area navigation (RNAV) procedures at the airport. This action would ensure the safety and management of instrument flight rules (IFR) operations within the National Airspace System.

We propose to supersede Airworthiness Directive (AD) 2012-22- 18, which applies to all Airbus SAS Model A330-243, -243F, -341, -342, and -343 airplanes. AD 2012-22-18 requires repetitive inspections of the three inner acoustic panels of both engine air intake cowls to detect disbonding, and corrective actions if necessary. Since we issued AD 2012-22-18, we have received additional reports of engine air inlet cowl collapse. This proposed AD would retain the requirements of AD 2012-22-18 with a reduced compliance time and reduced repetitive inspection intervals. This proposed AD would also provide for an optional modification that is terminating action for the repetitive inspections. These actions are specified in a European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. We are proposing this AD to address the unsafe condition on these products.
