Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-15469
Type: Proposed Rule
Date: 2012-06-25
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, - 900, and -900ER series airplanes. That NPRM proposed to require repetitive operational tests of the engine fuel suction feed of the fuel system, and other related testing if necessary. That NPRM was prompted by a report of an in-service occurrence of total loss of boost pump pressure of the fuel feed system, followed by loss of fuel system suction feed capability on one engine, and in-flight shutdown of the engine. This action revises that NPRM by proposing to require repetitive operational tests, and other related testing and corrective action if necessary. We are proposing this supplemental NPRM to detect and correct loss of the engine fuel suction feed capability of the fuel system, which in the event of total loss of the fuel boost pumps could result in dual engine flameout, inability to restart the engines, and consequent forced landing of the airplane. Since these actions impose an additional burden over that proposed in the previous NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Airworthiness Directives; Airbus Airplanes
Document Number: 2012-15461
Type: Proposed Rule
Date: 2012-06-25
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A330-243, -341, -342 and -343 airplanes. The existing AD currently requires modifying certain cowl assemblies of the left- and right-hand thrust reversers. Since we issued that AD, the manufacturer has issued new life limits on certain thrust reverser C-duct assemblies. This proposed AD would require removing certain C-duct assemblies of the left- and right-hand thrust reversers from service at certain designated life limits, and would also add airplanes to the applicability. We are proposing this AD to prevent fatigue cracking of the hinges integrated into the 12 o'clock beam of the thrust reversers, which could result in separation of a thrust reverser from the airplane, and consequent reduced controllability of the airplane.
Airworthiness Directives; The Cessna Aircraft Company Airplanes
Document Number: 2012-15451
Type: Proposed Rule
Date: 2012-06-25
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Cessna Aircraft Company Model 750 airplanes. This proposed AD was prompted by reports of direct current (DC) generator overvoltage events. This proposed AD would require replacing the auxiliary power unit (APU) generator control unit (GCU). We are proposing this AD to prevent DC generator overvoltage events, which could result in subsequent smoke in the cockpit and loss of avionics and electrical systems.

Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
Document Number: 2012-15325
Type: Rule
Date: 2012-06-25
Agency: Federal Aviation Administration, Department of Transportation
We are superseding an existing airworthiness directive (AD) for all Eurocopter Deutschland GmbH (ECD) Model MBB-BK 117 C-2 helicopters. That AD currently requires revising the ``Emergency and Malfunction Procedures'' and ``Performance Data'' sections of the Rotorcraft Flight Manual (RFM) by inserting three temporary pages into the RFM to alert pilots to monitor the power display when a generator is deactivated and provides procedures to prevent failure of the remaining generator. Before we issued that AD, the manufacturer developed a procedure to modify the two ``After Junction Boxes'' by removing a diode from each box, which provides terminating action for our AD requirements. These actions are intended to require implementing this terminating action to prevent an electrical power system failure and subsequent loss of control of the helicopter and revising the RFM accordingly, by removing the temporary pages inserted to comply with the superseded AD.
Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
Document Number: 2012-15290
Type: Rule
Date: 2012-06-25
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) that supersedes an existing Emergency Airworthiness Directive (EAD) for certain Eurocopter Deutschland GmbH (ECD) Model EC135 helicopters. The existing EAD, which was previously sent to all known U.S. owners and operators of ECD Model EC135 helicopters and not made generally effective by publication in the Federal Register, currently requires inspecting the ring frame between the rear structure tube (tailboom) and the tail rotor fenestron housing (fenestron housing) for a crack before the first flight of each day and replacing any cracked ring frame with an airworthy ring frame. Since we issued that EAD, we have determined that a pre-flight pilot check in conjunction with a recurring 25-hour inspection is sufficient for determining the airworthiness of the ring frame. Additionally, ECD has developed a modification that is terminating action for the requirements of that EAD. This superseding AD revises the inspection requirements of the EAD to allow an owner/operator to perform the pre-flight pilot check, adds a recurring inspection of the ring frame, and allows for installation of a ring frame reinforcement as an optional terminating action for the AD requirements. The actions are intended to detect a crack in the ring frame which could result in loss of the fenestron structure and subsequent loss of control of the helicopter.
Airworthiness Directives; Aeronautical Accessories, Inc., High Landing Gear Aft Crosstube Assembly
Document Number: 2012-15286

Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for the Aeronautical Accessories, Inc. (AAI), High Landing Gear Aft Crosstube Assembly (aft crosstube) installed on certain Bell Helicopter Textron, Inc. (Bell) and Agusta S.p.A. (Agusta) model helicopters as an approved Bell part installed during production or based on a Supplemental Type Certificate (STC). This AD requires certain recurring visual, dimensional, and fluorescent penetrant inspections of each aft crosstube, and replacing any cracked crosstube. This AD also requires establishing a life limit and creating a component history card or equivalent record for one of the affected part-numbered aft crosstubes. This AD was prompted by three reports of failed crosstubes because of cracks. The actions are intended to prevent failure of a crosstube, collapse of the landing gear, and subsequent loss of control of the helicopter.
