Federal Aviation Administration May 6, 2013 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2013-10652
Type: Proposed Rule
Date: 2013-05-06
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes. That NPRM proposed requiring repetitive inspections for cracking of the overwing frames, and corrective actions if necessary. That NPRM was prompted by multiple reports of cracks of overwing frames. This action revises that NPRM by revising the initial compliance time and providing an optional modification that would extend the compliance time for the next repetitive inspection. We are proposing this supplemental NPRM to detect and correct such cracking, which could sever a frame and increase the loading of adjacent frames, and could result in damage to the adjacent structure and consequent loss of structural integrity of the airplane. Since certain actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Special Conditions: Embraer, S.A., Model EMB-550 Airplane; Side-Facing Seats; Installation of Airbag Systems in Shoulder Belts
Document Number: 2013-10581
Type: Proposed Rule
Date: 2013-05-06
Agency: Federal Aviation Administration, Department of Transportation
This action proposes special conditions for the Embraer S.A. Model EMB-550 airplane. This airplane will have a novel or unusual design feature(s) associated with multiple place and single place side- facing seats and installation of airbag systems in the shoulder belts. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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.
Amendment of Class E Airspace; Easton, PA
Document Number: 2013-10539
Type: Rule
Date: 2013-05-06
Agency: Federal Aviation Administration, Department of Transportation
This action amends Class E Airspace at Easton, PA, as the Allentown VORTAC has been decommissioned and new Standard Instrument Approach Procedures have been developed at Braden Airpark. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also recognizes the airport's name change and updates the geographic coordinates of the airport.
Airworthiness Directives; Diamond Aircraft Industries GmbH Powered Gliders
Document Number: 2013-10270
Type: Rule
Date: 2013-05-06
Agency: Federal Aviation Administration, Department of Transportation
We are revising an airworthiness directive (AD) for certain Diamond Aircraft Industries GmbH Models HK 36 R, HK 36 TS, and HK 36 TTS powered gliders. AD 2013-04-08 required replacement of each elevator bell crank assembly and elevator bell crank mount. This AD retains the actions of AD 2013-04-08 but decreases gliders in the Applicability by removing the Model H-36 from the Applicability. This AD was prompted by reports of installation of an unsuitable self- locking nut on the bell crank of the elevator push rod that can cause failure of the elevator, resulting in loss of control. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2013-08992
Type: Rule
Date: 2013-05-06
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by reports of damaged fire seals on the forward edge of the thrust reverser. This AD requires inspecting to detect damage to the upper fire seals on the forward edge of the thrust reverser, where the fire seal contacts the 12-o'clock engine strut, and for correct stiffness and vent holes, and doing corrective actions if necessary; and installing a bracket for the fire seal. We are issuing this AD to detect and correct damage to the fire seals, which could allow airflow into the engine fire zone and could degrade the ability to extinguish an engine fire.
