Complementary Positioning, Navigation, and Timing Capability; Notice; Request for Public Comments
The purpose of this notice is to seek comment from the public and industry regarding potential plans by the United States Government to implement an enhanced Long Range Navigation (eLoran) system as a complementary positioning, navigation, and timing (PNT) capability to the Global Positioning System (GPS). The positioning, navigation, and timing performance of eLoran will vary widely depending on the number of transmitters and monitor sites for corrections that are implemented. The Department of Transportation seeks input on: (a) A brief description of your application(s) of positioning, navigation, and timing services; (b) the positioning, navigation, and/or timing performance required for a complementary PNT capability to support operations during a disruption of GPS that could last for longer than a day, (c) availability and coverage area required for a complementary PNT capability, (d) willingness to equip with an eLoran receiver to reduce or prevent operational and/or economic consequences from a GPS disruption, (e) current and planned availability of e-Loran capable user equipment, (f) other non-eLoran PNT technologies or operational procedures, currently available or planned, that could be used during a disruption of GPS for longer than a day.
40th Meeting: RTCA Special Committee 206, Aeronautical Information and Meteorological Data Link Services
The FAA is issuing this notice to advise the public of the fortieth meeting of the RTCA Special Committee 206, Aeronautical Information and Meteorological Data Link Services.
Nineteenth Meeting: RTCA Special Committee 222, AMS(R)S
The FAA is issuing this notice to advise the public of the nineteenth meeting of the RTCA Special Committee 222, AMS(R)S. Per RTCA PMC changes to the SC-222 Terms of Reference, this meeting will be a joint meeting with Eurocae WG-82. The SC-222 purpose will be to develop a joint work plan toward the revised Terms of Reference, and harmonize differences in deliverable items and schedule with WG-82.
Airworthiness Directives; Piper Aircraft, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-23-250, PA-24-250, PA-24-260, PA-24-400, PA-30, PA-31, PA-31-300, PA-31P, PA-39, and PA-E23-250 airplanes. This proposed AD was prompted by an accident caused by fuel starvation where the shape of the wing fuel tanks and fuel below a certain level in that tank may have allowed the fuel to move away from the tank outlet during certain maneuvers. This proposed AD would require installing a fuel system management placard on the aircraft instrument panel and adding text to the Limitations section of the pilot's operating handbook (POH)/airplane flight manual (AFM). We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2014-23-15 for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014- 23-15 required revising the maintenance or inspection program to incorporate new, more restrictive airworthiness limitations. This new AD retains the requirement to revise the maintenance or inspection program and removes a conflicting requirement. This AD was prompted by a determination that certain limitations required by AD 2014-23-15 conflict with limitations required by another AD. We are issuing this AD to prevent fatigue cracking, accidental damage, or corrosion in principal structural elements, and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding Airworthiness Directive (AD) 2014-06-08 for certain Bombardier, Inc. Model DHC-8-100, -200, and -300 series airplanes. AD 2014-06-08 required repetitive functional checks of the nose and main landing gear, and corrective actions if necessary; and also provided optional terminating action modification for the repetitive functional checks. This new AD requires a terminating action modification. This AD was prompted by a report that the emergency downlock indication system (EDIS) had given a false landing gear down- and-locked indication and a determination that a terminating action modification is necessary to address the identified unsafe condition. We are issuing this AD to detect and correct a false down-and-locked landing gear indication, which, on landing, could result in possible collapse of the landing gear.
