Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A340-600 series airplanes. This AD requires modifying the fire extinguishing system from a three-bottles solution with 4 flow metering compact unit into a two-bottles solution with 2 flow metering systems equipped with upgraded water absorbing filter elements. This AD was prompted by reports of partial blockage of a certain water absorbing filter element. We are issuing this AD to prevent partial blockage of a certain water absorbing filter element, which could lead to reduction of the halon outflow, which leads to incapacity to maintain fire extinguishing agent concentration. Combined with fire, this condition could result in an uncontrolled fire in the affected compartment.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all Model 747SP series airplanes. This AD was prompted by a report of a rudder hard-over event on a Model 747-400 series airplane, caused by a rudder power control module (PCM) manifold cracking and separating in the area of the yaw damper cavity end-cap. This condition could result in a hard-over of the rudder surface leading to an increase in pilot workload and a possible high-speed runway excursion upon landing, in the event of failure of the lower or upper rudder PCM manifold. This AD requires replacing or modifying the upper and lower rudder PCMs. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by a report that the top 3 inches of the aero/fire seals of the blocker doors on the thrust reverser torque boxes are not fireproof. This AD requires a one-time inspection to determine the part numbers of the aero/fire seals of the blocker doors on the thrust reverser torque boxes on the engines, and replacing affected aero/fire seals with new, improved aero/fire seals. We are issuing this AD to prevent a fire in the fan compartment (a fire zone) from migrating through the seal to a flammable fluid in the thrust reverser actuator compartment (a flammable fluid leakage zone), which could result in an uncontrolled fire.
Clarification of Policy Regarding Approved Training Programs; Correction
The FAA is correcting a notice published on December 27, 2011 (76 FR 80831). In that notice of availability the FAA announced the availability of an FAA Notice that would require FAA inspectors to review policy regarding approved training programs as well as to identify and correct those training programs which erroneously issued credit for previous training or checking. The Notice also provided guidance on constructing reduced hour training programs based on previous experience. Upon review of the comments and any necessary revision, the Notice would cancel and replace FAA Order 8900.1, Volume 3, Chapter 19, Paragraph 3-1111. This document corrects an incorrect comment due date.
Airworthiness Directives; Eurocopter Deutschland GMBH Helicopters
We propose to adopt a new airworthiness directive (AD) for Eurocopter Deutschland GMBH (ECD) Model MBB-BK 117 C-1 and C-2 helicopters. This proposed AD would require installing a placard that corresponds to the maximum permissible flight altitude, amending the Rotorcraft Flight Manual (RFM) to revise the maximum permissible operating altitude, and inserting revised performance charts into the RFM. The proposed AD would also require a repetitive maintenance ``MAX N1 CHECK'' to determine the appropriate maximum altitudes. The AD would also require, if the engine or a fuel control unit (FCU) or module 2 or 3 is replaced, repeating the maintenance ``MAX N1 CHECK.'' Finally, the proposed AD specifies that modifying both engines would provide terminating action for the proposed AD requirements. This proposed AD is prompted by the failure of a ``few'' engines to reach the specified one-engine-inoperative (OEI) rating at altitudes above 10,000 feet. The proposed actions are intended to prevent flights at altitudes where the full OEI engine power cannot be reached and subsequent loss of control of the helicopter if an OEI operation is required.
Public Notice for Release of Aeronautical Property at New Castle Airport (ILG), New Castle, DE
The Federal Aviation Administration (FAA) is requesting public comment on the Delaware River and Bay Authority's (DRBA) request to grant the Delaware Department of Transportation a permanent easement on 2.424 +/- acres of airport property along portions of Old Churchman's Road bordering a portion of the Airport property perimeter for roadway improvements. The 2.424 +/- acres land covered by the purposed easement will no longer be dedicated for aviation use by the New Castle Airport. The DRBA, as operator of the New Castle Airport (ILG), has proposed the extension of Taxiway ``H'' and the development of an approximate thirty-eight (38) acre parcel of airport property on the southeasterly side of Old Churchman's Road for aviation related purposes. The Thirty- Eight Acre Parcel is currently undeveloped and separated from the main airport property by Old Churchman's Road. In order to gain connectivity and access to the Thirty-Eight Acre Parcel and allow for the extension of Taxiway ``H'' and future development, 0.610 +/- acres of Old Churchman's Road must be vacated by the Delaware Department of Transportation and returned to New Castle County as fee owner for aeronautical use. Once the 0.610+/- acres of Old Churchman's Road is vacated, future road improvements to include, but not limited to, the upgrade of Old Churchman's Road from Route 13 to the easterly boundary of the Thirty-Eight Acre Parcel, the construction of a public road connecting Old Churchman's Road and New Churchman's Road at the eastern boundary of the Thirty-Eight Acre Parcel, and the construction of certain improvements along New Churchman's Road can be made on the proposed 2.424 +/- acre easement area. This will allow Delaware Department of Transportation to bring portions of Old Churchman's Road up to standards and accommodate a new connector from Old Churchman's Road to New Churchman's Road. The 2.424 +/- acre parcel is located at New Castle Airport (ILG), New Castle, DE, situated northwesterly of Dupont Highway, U.S. Route 13 and northeasterly of New Churchman's Road, Delaware State Road 58, New Castle Hundred, New Castle County, Delaware. The parcel is comprised of several small, narrow, Right-of-Way easement ``strips'' totaling 2.424 +/- acres in aggregate and is generally located along Old Churchman's Road commencing at Route 13 and running in a westerly direction to the easterly property line of the Thirty-Eight Acre Parcel. The property is currently depicted on the Airport Layout Plan (ALP) of record as airport property and consists of five sections of narrow strips of land varying 1.272 acres to 0.054 acres. The strips of land are parts of Tax Parcel No. 10-018.00-006. These areas, totaling 2.424 +/-, acres are not required for aeronautical use and can be used for road improvements.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 series airplanes; Model A330-300 series airplanes, Model A340-200 series airplanes; Model A340-300 series airplanes; Model A340-541 airplanes; and Model A340-642 airplanes. This proposed AD was prompted by reports of cracks in the bogie pivot pin caused by material heating due to friction between the bogie pivot pin and bush. This proposed AD would require performing a detailed inspection for degradation of the bogie pivot pins and pivot pin bushes of the main and central landing gear for any cracks and damage, and repairing or replacing bogie pivot pins and pivot pin bushes, if necessary. We are proposing this AD to correct and detect cracks and damage to the main and central landing gear, which could result in the collapse of the landing gear and adversely affect the airplane's continued safe flight and landing.
Special Conditions: Learjet Inc., Learjet Model LJ-200-1A10; Interaction of Systems and Structures
These special conditions are issued for the Learjet Model LJ- 200-1A10 airplane. This airplane will have novel or unusual design features associated with systems that, directly or as a result of failure or malfunction, affect structural performance. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These 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; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes equipped with analog transient suppression devices (ATSDs) installed in accordance with Supplemental Type Certificate number ST00146BO. This proposed AD was prompted by multiple reports of corrosion on ATSDs. This proposed AD would require revising the maintenance program to incorporate certain limitations. We are proposing this AD to detect and correct corrosion on ATSDs, which could result in the loss of high voltage transient protection (e.g., lightning protection) in the fuel tanks and consequent fuel tank explosion and loss of the airplane.
Airworthiness Directives; Bombardier Inc. Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to certain Bombardier Inc. Model CL-215-1A10 and CL- 215-6B11 (CL-215T Variant) airplanes. The existing AD currently requires repetitive inspections to detect cracking of the lower cap of the wing front and rear spars at wing station (WS) 51.00, and the wing lower skin. Additional actions, if cracking is found, include reworking the lower cap of the front or rear spar, inspecting for cracking, and repairing any cracking. The existing AD also requires reporting inspection results. Since we issued that AD, we have received reports of cracking found outside the inspection area. This proposed AD would extend the inspection area of the rear spar lower cap from WS 51.00 to WS 49.50 and modify the ultrasonic inspection calibration procedure. We are proposing this AD to detect and correct cracking of the lower caps of the wing front spar and rear spar, and lower wing skin, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 767 airplanes. The existing AD currently requires an inspection to detect cracks and fractures of the outboard hinge fitting assemblies on the trailing edge of the inboard main flap, and follow-on and corrective actions if necessary. For certain airplanes, the existing AD also requires a one- time inspection to determine if a tool runout option has been performed in the area. Since we issued that AD, we have received reports of hinge assembly fractures found before the currently-required inspection cycle compliance times on certain airplanes. This proposed AD reduces compliance times for Model 767-400ER series airplanes. In addition, this proposed AD would revise the applicability to include an additional airplane. We are proposing this AD to prevent the inboard aft flap from separating from the wing and potentially striking the airplane, which could result in damage to the surrounding structure and potential personal injury.
Notice of Proposed Policy Clarification for the Registration of Aircraft to U.S. Citizen Trustees in Situations Involving Non-U.S. Citizen Trustors and Beneficiaries
Notice is hereby given of the FAA's proposed policy regarding the registration of aircraft to U.S. Citizen Trustees in situations involving Non-U.S. citizen trustors and beneficiaries.
Airworthiness Directives; Superior Air Parts, Lycoming Engines (Formerly Textron Lycoming), and Continental Motors, Inc., Fuel-Injected Reciprocating Engines
We are superseding an existing airworthiness directive (AD) for Superior Air Parts and Lycoming Engines fuel-injected reciprocating engines. That AD currently requires removing AVStar Fuel Systems, Inc. (AFS) fuel servos installed after May 20, 2010, if the servo contained an AFS diaphragm, part number (P/N) AV2541801 or P/N AV2541803, from certain production lots. This AD expands the applicability, and changes the compliance interval for all affected Superior Air Parts, Lycoming Engines, and Continental Motors, Inc., fuel-injected reciprocating engines. This AD was prompted by an accident involving a Piper PA32R- 301 airplane, and by the discovery of additional engines being affected by the unsafe condition since we issued the existing AD. We are issuing this AD to prevent an in-flight engine shutdown due to a failed fuel servo diaphragm, and damage to the airplane.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We are adopting a new airworthiness directive (AD) for all Rolls-Royce plc RB211-Trent 500 series turbofan engines. This AD requires a one-time inspection of the fuel tubes and fuel tube clips for evidence of damage, wear, and fuel leakage. This AD was prompted by reports of wear found between the securing clips and the low-pressure (LP) fuel tube outer surface, which reduces the fuel tube wall thickness, leading to fracture of the fuel tube and consequent fuel leak. We are issuing this AD to prevent engine fuel leaks, which could result in risk to the airplane.
Airworthiness Directives; Honeywell International Inc. TPE331-10 and TPE331-11 Series Turboprop Engines
We are adopting a new airworthiness directive (AD) for the products listed above. This AD was prompted by a report of an uncontained failure of a first stage turbine disk that had a metallurgical defect. This AD requires inspecting certain serial number (S/N) first stage turbine disks, part number (P/N) 3101520-1 and P/N 3107079-1. We are issuing this AD to prevent uncontained failure of the first stage turbine disk and damage to the airplane.
Airworthiness Directives; CFM International, S.A. Turbofan Engines
We are adopting a new airworthiness directive (AD) for certain CFM International, S.A. model CFM56-5B series turbofan engines. This AD was prompted by a normal quality sampling at CFM International, S.A. that isolated a production batch of fan blades with nonconforming geometry of mid-span shroud tips of the fan blades. This AD requires removing from service certain serial number (S/N) fan blades. We are issuing this AD to prevent an inflight shutdown (IFSD) of one or more engines following foreign object damage (FOD) or a bird strike.
Airworthiness Directives; CPAC, Inc. Airplanes
We are superseding an existing airworthiness directive (AD) for all CPAC, Inc. (type certificate formerly held by Commander Aircraft Corporation, Gulfstream Aerospace Corporation, and Rockwell International) Models 112, 112B, 112TC, 112TCA, 114, 114A, 114B, and 114TC airplanes. That AD currently requires a one-time inspection of the elevator spar for cracks and, if any crack is found, either replace with a serviceable elevator spar that is found free of cracks or repair/modify the elevator spar with an FAA-approved method. That AD also requires reporting to the FAA the results of the inspection. Since we issued that AD, using the data collected through the reporting requirement, we have determined there is a need for continued inspections. This new AD requires repetitive inspections of the elevator spar for cracks and, if any crack is found, either replacing with a serviceable elevator spar that is free of any cracks and/or corrosion or repairing/modifying the elevator spar with an FAA-approved procedure. We are issuing this AD to correct the unsafe condition on these products.
