Proposed Establishment of Class E Airspace; Hazen, NV
This action proposes to establish Class E airspace at the Hazen VHF Omni-Directional Radio Range Tactical Air Navigation Aid (VORTAC), Hazen, NV, to facilitate vectoring of Instrument Flight Rules (IFR) aircraft under control of Oakland Air Route Traffic Control Center (ARTCC). The FAA is proposing this action to enhance the safety and management of aircraft operations within the National Airspace System.
Amendment of Restricted Area Boundary Descriptions; Cape Canaveral, FL
This action makes minor adjustments to the boundary descriptions of restricted areas R-2932, R-2933, R-2934 and R-2935 at Cape Canaveral, FL. The changes are required based on more accurate digital plotting of points that revealed minor mismatches between adjacent boundaries. The R-2933 description is also amended to remove exclusionary wording that no longer applies.
Airworthiness Directives; Sikorsky Aircraft Corporation (Type Certificate Previously Held by Schweizer Aircraft Corporation) Helicopters
We propose to adopt a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (type certificate previously held by Schweizer Aircraft) (Sikorsky) Model 269D and Model 269D Configuration A helicopters. This proposed AD would require reducing the life limit of the ring gear carrier assembly. This proposed AD is prompted by cracks in the ring gear carrier assembly. The proposed actions are intended to reduce the life of the ring gear carrier assembly to prevent failure of the main rotor transmission, loss of engine power to the main rotor, and subsequent loss of control of the helicopter.
Airworthiness Directives; the Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain the Boeing Company Model 737-700, -800, and -900ER series airplanes. This proposed AD was prompted by reports of troughs in the skin along the chem-mill pocket edges of certain fuselage crown skin panel assemblies. This proposed AD would require repetitive inspections to detect cracking in the crown skin panel assembly. This proposed AD would also provide optional terminating action for the repetitive inspections. We are proposing this AD to detect and correct cracking from troughs in the chem-mill pocket edges, which could lead to rapid decompression of the airplane.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A319 and A320 series airplanes. This proposed AD was prompted by a report that fatigue cracking could appear at certain fastener locations in the longeron area below the emergency exit cut- outs. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would require modification of eight fastener locations in the longeron area below the emergency exit cut-outs on the left-hand (LH) and right-hand (RH) sides. We are proposing this AD to detect and correct cracking at certain fastener locations in the longeron area below the emergency exit cut-outs, which could lead to failure of the fasteners and reduced structural integrity of the airplane.
Airworthiness Directives; the Boeing Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2013-14- 05, which applies to certain The Boeing Company Model 747-400 and 747- 400F series airplanes. AD 2013-14-05 currently requires repetitive inspections of the longeron extension fittings for cracking, and related investigative and corrective actions if necessary. AD 2013-14- 05 also provides optional terminating action for the repetitive inspections. Since we issued AD 2013-14-05, we determined that more work is necessary on airplanes on which a terminating action (permanent repair, longeron extension fitting replacement, or modification) was accomplished. This proposed AD would continue to require the requirements of AD 2013-14-05, and would add new repetitive high frequency eddy current (HFEC) inspections of any modified, repaired, or replaced longeron extension fitting for cracking, and applicable related investigative and corrective actions if necessary. We are proposing this AD to detect and correct cracks in the longeron extension fittings, which can become large and adversely affect the structural integrity of the airplane.
