Notice of Request To Release Airport Property
Document Number: 2012-23275
Type: Notice
Date: 2012-09-20
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to rule and invites public comment on the release of land at the Meade Municipal Airport (MEJ), Meade, Kansas, under the provisions of 49 U.S.C. 47107(h)(2).
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-23218
Type: Proposed Rule
Date: 2012-09-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. The existing AD currently requires repetitive inspections of the aft attach lugs of the elevator tab control mechanisms, and replacement of any discrepant elevator tab control mechanism. Since we issued that AD, Boeing has developed a modification of the aft attach lugs of the elevator tab control mechanisms, which will adequately address the unsafe condition. This proposed AD would require replacing the left and right elevator tab control mechanisms with elevator tab control mechanisms that have the modified attach lugs, which would terminate the existing requirements. We are proposing this AD to prevent discrepancies in the aft attach lugs of the elevator tab control mechanism, which could result in severe elevator and tab vibration. Consequent structural failure of the elevator or horizontal stabilizer could result in loss of structural integrity and aircraft control.
Airworthiness Directives; Airbus Airplanes
Document Number: 2012-23217
Type: Proposed Rule
Date: 2012-09-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-300 series airplanes and Model A340-200 and -300 series airplanes. This proposed AD was prompted by reports that, during a flight test, several spoiler servo-controls (SSCs) did not remain locked in the retracted position (hydraulic locking function) after manual depressurization of the corresponding hydraulic circuit. Loss of that locking functionwhich is ensured by a blocking valvewas caused by an internal leak from a sheared seal on the blocking valve. This proposed AD would require inspecting to determine if certain SSCs are installed, performing an operational test of any affected SSC, and replacing if necessary. We are proposing this AD to prevent loss of the hydraulic locking function during take-off and go-around phases, which, in combination with malfunction of one engine, could result in reduced controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-23150
Type: Proposed Rule
Date: 2012-09-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-300, 737-400, 737-500, and 757-200 series airplanes. This proposed AD was prompted by a report of damage caused by electrical arcing to the wires that connect seat electronics boxes (SEBs). This proposed AD would require installing a new relay and doing certain wiring changes of the entertainment control switch if necessary. We are proposing this AD to prevent power from being supplied to passenger seats when the entertainment control switch is in the OFF position, which could cause an electrical shock hazard resulting in serious or fatal injury to maintenance personnel.
Airworthiness Directives; Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
Document Number: 2012-23149
Type: Proposed Rule
Date: 2012-09-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Model Gulfstream G150 airplanes. This proposed AD was prompted by a review that determined that the runway slope and anti-ice corrections to V1 and take-off distances in the Gulfstream G150 Airplane Flight Manual (AFM) were presented in a non-conservative manner. This proposed AD would require revising the performance section of the AFM to include procedures to advise the flightcrew of certain runway slope and anti-ice corrections and take- off distance values. We are proposing this AD to prevent the use of published non-conservative data, which could result in the inability to meet the required take-off performance, with consequent hazard to safe operation during performance-limited take-off operations.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-23148
Type: Proposed Rule
Date: 2012-09-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by a report of chafing damage to a wire bundle that was arcing to hydraulic tubing and caused by insufficient separation between the wire bundle and the hydraulic tubing in the main landing gear (MLG) wheel well. This proposed AD would require an inspection for damage of wire bundles and hydraulic tubing on the right side of the forward bulkhead of the MLG wheel well; installation of new clamps; and corrective actions, as applicable. We are proposing this AD to detect and correct possible damage caused by insufficient separation between the wire bundles and hydraulic tubing to prevent electrical arcing in a flammable fluid leakage zone, which could lead to a wheel well fire.
Airworthiness Directives; Airbus Airplanes
Document Number: 2012-23147
Type: Proposed Rule
Date: 2012-09-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-202, -203, -223, -243, -302, -323, -342, and -343 airplanes; and Model A340-313 airplanes. This proposed AD was prompted by reports that a specific batch of cargo doors might have deviations in quality related to door structure, such as irregular bore holes, improper application of sealant and paint, or uncleanliness. This proposed AD would require inspecting to identify the part and serial numbers of the forward and aft cargo doors, and replacing the affected cargo doors. We are proposing this AD to prevent the degraded structural capability of the cargo door, a primary structure, from leading to failure of the door, which could lead to a breach through the door or the door detaching from the airplane, resulting in potential rapid decompression.
Technical Amendment; Airworthiness Standards: Aircraft Engines; Correction
Document Number: 2012-23105
Type: Rule
Date: 2012-09-20
Agency: Federal Aviation Administration, Department of Transportation
The FAA is correcting a technical amendment published on July 5, 2012 (77 FR 39623). In that technical amendment, the FAA clarified aircraft engine vibration test requirements in the airworthiness standards. The technical amendment was in response to inquiries from applicants requesting FAA engine type certifications and aftermarket certifications, such as supplemental type certificates, parts manufacturing approvals, and repairs. We revised the regulation to clarify that engine surveys require an engine test. Representatives of industry suggested that our technical amendment was in fact, a substantive change in the regulation, not a clarification. The FAA is correcting our prior action in response to that industry claim. This document amends the FAA's regulations to reverse the changes to Sec. 33.83(a) amendment 33-33 and restore Sec. 33.83(a) to its previous amendment 33-17.
