Airworthiness Directives; McCauley Propeller Systems Five-Blade Propeller Assemblies
The FAA proposes to supersede an existing airworthiness directive (AD) for certain McCauley Propeller Systems propeller assemblies. That AD currently requires removing certain propeller hubs from service at new, reduced life limits and eddy current inspections (ECIs) of the propeller hub. This proposed AD would require removing certain propeller hubs from service before they exceed 6,000 hours time-since-new (TSN). This proposed AD results from a report of a crack in a propeller hub. We are proposing this AD to prevent cracked propeller hubs, which could cause failure of the propeller hub, blade separation, and loss of control of the airplane.
Proposed Amendment of Class E Airspace; Williston, ND
This action proposes to amend Class E airspace at Williston, ND. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Sloulin Field International Airport, Williston, ND. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport. Adjustments to the geographic coordinates of the airport also would be made.
Proposed Establishment of Class E Airspace; Port Clarence, AK
This action proposes to establish Class E airspace at Port Clarence Coast Guard Station (CGS), AK. The United States Coast Guard operates into this airstrip and has developed a military-use instrument approach procedure. This instrument approach development at the Port Clarence CGS Airport has made this action necessary to enhance safety and management of Instrument Flight Rules (IFR) operations.
Airworthiness Directives; Honeywell International Inc. Auxiliary Power Unit Models GTCP36-150(R) and GTCP36-150(RR)
The FAA is adopting a new airworthiness directive (AD) for Honeywell International Inc. auxiliary power unit (APU) models GTCP36- 150(R) and GTCP36-150(RR). This AD requires inspecting the fuel control unit (FCU) differential pressure (Delta P) sleeve bore for erosion, replacing the FCU if it fails the inspection, and installing a fuel deflector on the Delta P sleeve of the FCU. This AD results from eight reports of fuel leakage from the FCU. We are issuing this AD to prevent fuel leakage in the APU compartment, which could lead to ignition of fuel vapor, creating a fire and explosion hazard resulting in injury, and damage to the APU and the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135ER, -135KE, -135KL, and -135LR Airplanes; and EMBRAER Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Cessna Aircraft Company Model 525A Airplanes
We are adopting a new airworthiness directive (AD) to supersede AD 2009-24-13, which applies to certain Cessna Aircraft Company (Cessna) Model 525A airplanes. AD 2009-24-13 currently requires you to repetitively inspect the thrust attenuator paddle assemblies for loose and damaged fasteners and for cracks. AD 2009-24-13 also requires you to replace loose or damaged fasteners and replace cracked thrust attenuator paddles found during any inspection. Since we issued AD 2009-24-13, Cessna has developed new design thrust attenuator paddles and universal head rivets as terminating action for the repetitive inspections. Consequently, this AD would retain the requirements of AD 2009-24-13 until replacement of both thrust attenuator paddles and the eight countersunk fasteners with new design thrust attenuator paddles and universal head rivets. We are issuing this AD to detect and correct loose and damaged fasteners and cracks in the thrust attenuator paddles, which could result in in-flight departure of the thrust attenuator paddles. This failure could lead to rudder and elevator damage and result in loss of control.
Airworthiness Directives; Mitsubishi Heavy Industries, Ltd. Various Models MU-2B Airplanes
We are adopting a new airworthiness directive (AD) to supersede Airworthiness Directive (AD) 2006-17-01, AD 2006-15-07, AD 2000-02-25, and AD 97-25-02, which applies to certain Mitsubishi Heavy Industries, Ltd. (MHI) various Models MU-2B airplanes. An FAA MU-2B safety evaluation resulted in the standardization of the MU-2B specific training and the FAA-accepted pilot operating checklists through a special Federal aviation regulation (SFAR). MHI revised the airplane flight manuals (AFMs) to align them with the information in that training and the checklists. In addition, incorporating all AFM revisions up to and including this latest AFM revision will incorporate all AFM compliance actions required by the four above-mentioned ADs. This AD would retain from AD 2006-17-01 the inspection of the engine torque indication system and possible recalibration of the torque pressure transducers and would require incorporating all revisions up to and including the latest revisions of the AFM. We are issuing this AD to correct inconsistencies in critical operating procedures between the MU-2B specific training, the FAA-accepted pilot operating checklists, and the AFMs, which, if not corrected, could result in the pilot inadvertently taking inappropriate actions in critical operating conditions.
