Proposed Amendment of Class E Airspace; Gustavus, AK
This action proposes to amend Class E airspace at Gustavus Airport, Gustavus, AK. Decommissioning of the Gustavus Nondirectional Radio Beacon (NDB) has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also would adjust the geographic coordinates of the airport.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747 airplanes. This proposed AD was prompted by reports of cracking in the forward and aft inner chord of the body station (BS) 2598 bulkhead near the upper corners of the cutout for the horizontal stabilizer rear spar, and cracking in the bulkhead upper and lower web panels near the inner chord to shear deck connection. This proposed AD would require doing repetitive inspections for cracking in the bulkhead splice fitting, frame supports, forward and aft inner chords, and floor support; doing an inspection for cracking in the bulkhead upper web, doubler, and bulkhead lower web; and corrective actions if necessary; for certain airplanes, inspections for cracking in the repaired area of the bulkhead, and corrective actions if necessary; for certain airplanes, support frame modification and support frame inspections, and related investigative and corrective actions, if necessary; for certain airplanes, repetitive support frame post-modification inspections and inspections for cracking in the hinge support, and related investigative and corrective actions if necessary; for certain airplanes, a one-time inspection of the frame web and upper shear deck (floor support) chord aft side for fasteners; and a one-time inspection of the upper forward inner chord, frame support fitting and splice fitting, for the installation of certain fasteners; and related investigative and corrective actions if necessary; for certain airplanes, a one-time inspection of the upper forward inner chord, frame support fitting and splice fitting for the installation of certain fasteners; a one-time inspection for any repair installed on the left and right side of the aft inner chord, and related investigative and corrective actions, if necessary; for certain airplanes, a one-time inspection of the support frame outer chord for cracking, and repair if necessary; and repetitive support frame post-repair inspections, and corrective actions, if necessary. We are proposing this AD to detect and correct fatigue cracking of the BS 2598 bulkhead structure, which could adversely affect the structural integrity of the bulkhead and the horizontal stabilizer support structure and result in loss of controllability of the airplane.
Public Notice for a Change in Use of Aeronautical Property and Long-Term Lease Approval at Harrisburg International Airport (MDT), Middletown, PA
The Federal Aviation Administration is requesting public comment on the Susquehanna Area Regional Airport Authority's request to change 22 acres of airport property from aeronautical use to non- aeronautical use. The request also solicits approval for entering into a long-term lease for 2.893 acres within this area for a retail convenience store. The parcel is located at Harrisburg International Airport (MDT) in Lower Swatara Township, Dauphin County, PA. The property is currently depicted on the Airport Layout Plan of record as airport property and consists of unimproved, undeveloped vacant land, which is partially paved and fenced. The land lies at the Northeast intersection of W. Harrisburg Pike (US Route 230) and Meade Avenue in Middletown, PA. The Parcel is further identified as Dauphin County identification parcels 36-023-008 and 009. The airport is proposing re-designating this 22- acre area as available for non-aeronautical use. The requested change is for the anticipated purpose of permitting the Airport Owner to enter into long-term lease agreements for commercial property development as a retail commercial center, consistent with the findings of The Highest and Best Use Study completed in 2011. A 2.893 acres sub parcel located within the subject area is ready to be developed. No land shall be sold as part of this land release request. This action will allow the re- designation of the 22-acre area, known as the ``North 29'', as land available for non-aeronautical use on the Airport Layout Plan (ALP). In addition, approval is sought by the Airport Authority to enter into a long-term lease agreement with a retail convenience store to be located on a 2.893 acre sub-parcel located within the 22-acre plot. The documents reflecting the Sponsor's request are available, by appointment only, for inspection at the Harrisburg International Airport, Executive Director's Office and the FAA Harrisburg Airport District Office in Camp Hill, PA.
Special Conditions: Embraer S.A., Model EMB-550 Airplanes; Flight Envelope Protection: General Limiting Requirements
These special conditions are issued for the Embraer S.A. Model EMB-550 airplane. This airplane will have a novel or unusual design feature, specifically new control architecture and a full digital flight control system which provides flight envelope protections. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Special Conditions: Embraer S.A., Model EMB-550 Airplane, Dive Speed Definition With Speed Protection System
These special conditions are issued for the Embraer S.A. Model EMB-550 airplane. This airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These design features include a high-speed protection system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Special Conditions: Embraer S.A., Model EMB-550 Airplane; Landing Pitchover Condition
These special conditions are issued for the Embraer S.A. Model EMB-550 airplane. This airplane will have a novel or unusual design feature associated with landing loads due to the automatic braking system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; Sikorsky Aircraft Corporation-Manufactured (Sikorsky) Model Helicopters (type certificate currently held by Erickson Air-Crane Incorporated)
We propose to supersede an existing airworthiness directive (AD) for Sikorsky Aircraft Corporation-manufactured Model S-64E helicopters (type certificate currently held by Erickson Air-Crane Incorporated (Erickson)). That AD currently requires inspecting and reworking the main gearbox (MGB) assembly second stage lower planetary plate (plate). This action would establish or reduce the life limits for certain flight-critical components, remove from service various parts, require repetitive inspections and other corrective actions, and require replacing any cracked part discovered during an inspection. This proposal is prompted by further analysis performed by the current type certificate holder and the service history of certain parts. The actions specified in the proposed AD are intended to prevent a crack in a flight critical component, failure of a critical part, and subsequent loss of control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron, Inc., Helicopters
We are revising an earlier proposed airworthiness directive (AD) for Bell Helicopter Textron, Inc. (Bell), Model 214B and B-1 helicopters, which proposed to require inspecting certain pylon support spindle assemblies (spindles) for any corrosion, or a nick, scratch, dent, or crack, and repairing or replacing any unairworthy spindle before further flight. This SNPRM proposes to revise those requirements by updating the cost of compliance, revising the recording requirements, adding a requirement to reduce the retirement life of an installed spindle, and adding Bell Model 214ST to the applicability.
Establishment of Class E Airspace; Beeville-Chase Field, TX
This action makes a correction to the title and airspace description of a final rule published in the Federal Register of March 28, 2013. The title and airspace designation are corrected to read Beeville-Chase Field, TX.
Harmonization of Airworthiness Standards-Gust and Maneuver Load Requirements
The FAA proposes to amend certain airworthiness regulations for transport category airplanes based on recommendations from the Aviation Rulemaking Advisory Committee (ARAC). Adopting this proposal would eliminate certain regulatory differences between the airworthiness standards of the FAA and European Aviation Safety Agency (EASA) without affecting current industry design practices. This action would revise the pitch maneuver design loads criteria; revise the gust and turbulence design loads criteria; revise the application of gust loads to engine mounts, high lift devices, and other control surfaces; add a ``round-the-clock'' discrete gust criterion and a multi-axis discrete gust criterion for airplanes equipped with wing-mounted engines; revise the engine torque loads criteria; add an engine failure dynamic load condition; revise the ground gust design loads criteria; revise the criteria used to establish the rough air design speed, and require the establishment of a rough air Mach number.
