Notice of Intent To Rule on Request To Release Airport Property at the St. George Airport, St. George, UT
Document Number: 2012-23556
Type: Notice
Date: 2012-09-25
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to rule and invite public comment on the release of land at St. George Airport under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21), now 49 U.S.C. 47107(h)(2).
Special Conditions: Embraer S.A. Model EMB-550 Airplanes, Sudden Engine Stoppage
Document Number: 2012-23536
Type: Proposed Rule
Date: 2012-09-25
Agency: Federal Aviation Administration, Department of Transportation
This action proposes special conditions for the Embraer Model EMB-550 airplane. This airplane will have a novel or unusual design feature associated with the effects of sudden engine stoppage upon the airframe. 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.
Airworthiness Directives; Eurocopter France Helicopters
Document Number: 2012-23460
Type: Proposed Rule
Date: 2012-09-25
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the Eurocopter France (Eurocopter) Model AS332C, AS332L, and AS332L1 helicopters. This proposed AD is prompted by reports of electro-valve power supply disruptions while a helicopter is on the ground, causing the landing gear to retract and the helicopter nose to drop. This results in damage to the forward section of the helicopter's bottom structure. This proposed AD would require modifying the main landing gear control panel (control panel) 33G, connector 100G, and wiring. It also would require tests to ensure that these modifications function correctly. We propose this AD to prevent an uncommanded landing gear retraction that would cause the helicopter nose to drop and hit the ground while the rotor blades are spinning.
Airworthiness Directives; Eurocopter France Helicopters
Document Number: 2012-23448
Type: Rule
Date: 2012-09-25
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC 155B, EC155B1, SA-365N1, AS- 365N2 and AS 365 N3 helicopters to require visually inspecting the tail rotor hub (TRH) for a crack and removing the TRH if a crack exists. This AD is prompted by reports of cracks on two TRHs. These actions are intended to prevent the tail rotor from jamming, which could lead to reduced or loss of control of the helicopter.
Airworthiness Directives; Eurocopter France (Eurocopter) Helicopters
Document Number: 2012-23444
Type: Proposed Rule
Date: 2012-09-25
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Eurocopter Model SA-365N1, AS-365N2, and AS365N3 helicopters. This proposed AD would revise the Limitations section of the Rotorcraft Flight Manual (RFM) to prohibit flight in instrument meteorological conditions (IMC) or night visual flight rules (VFR) for each helicopter with a vertical gyro unit GV76-1 installed upon a non-reinforced shelf in the rear cargo compartment. Also, this proposed AD would require modifying the GV76-1 vertical gyro unit shelf and testing for correct function of the navigation systems. This proposed AD is prompted by flight crew reports of deviations between the displayed attitude on the attitude display screen and the independent electromechanical standby attitude indicator. The proposed actions are intended to prevent an undetected flight display error of a slow drift in the roll axis, disorientation of the pilot, and subsequent loss of control of the helicopter.
