Operating Limitations at New York Laguardia Airport; Proposed Amendments
The Federal Aviation Administration (FAA) has tentatively determined that it is necessary to amend further its December 12, 2006 Order that temporarily caps scheduled operations at New York's LaGuardia Airport (LaGuardia), pending the implementation of a longer- term regulation to manage congestion at the airport. In particular, we now propose to accept from air carriers voluntary reductions in scheduled operations at the airport to a targeted average of 71 hourly scheduled operations for the duration of the Order. This proposed reduction in flight operations at LaGuardia would not affect the number of unscheduled operations at the airport. The FAA is separately extending the Order's expiration until 11:59 p.m., Eastern Time, on October 24, 2009.

Proposed Establishment of Low Altitude Area Navigation Route (T-Route); Rockford, IL
This action proposes to establish a low altitude Area Navigation (RNAV) route, designated T-265, in the Chicago/Rockford International Airport, IL, terminal area. T-routes are low altitude Air Traffic Service routes, based on RNAV, for use by aircraft that have instrument flight rules (IFR) approved Global Positioning System (GPS)/ Global Navigation Satellite System (GNSS) equipment. This action would enhance safety and improve the efficient use of the navigable airspace in the Chicago/Rockford International Airport, IL, terminal area west of Chicago, IL.
Airworthiness Directives; Cessna Aircraft Company 172, 175, 177, 180, 182, 185, 188, 206, 207, 208, 210, 303, 336, and 337 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) 172, 175, 177, 180, 182, 185, 188, 206, 207, 208, 210, 303, 336, and 337 series airplanes. This AD requires you to inspect the alternate static air source selector valve to assure that the part number identification placard does not obstruct the alternate static air source selector valve port. If the part number identification placard obstructs the port, this AD also requires you to remove the placard, assure that the port is unobstructed, and report to the FAA if obstruction is found. This AD results from reports of airplanes found with alternate static air source selector valve port obstruction caused by improper installation of the part number identification placard. The actions specified by this AD are intended to prevent erroneous indications from the altimeter, airspeed, and vertical speed indicators, which could cause the pilot to react to incorrect flight information and possibly result in loss of control.
Airworthiness Directives; Piper Aircraft, Inc. Models PA-46-350P, PA-46R-350T, and PA-46-500TP Airplanes
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) Models PA-46-350P, PA-46R-350T, and PA-46- 500TP airplanes. This AD requires you to install a stall warning heat control modification kit. This AD results from ice forming on the stall vane heater during flights into icing conditions with the landing gear down. We are issuing this AD to prevent ice from forming on the stall vane, which may result in failure of the stall warning system. This failure could result in the pilot being unaware of an approaching stall situation.
Airworthiness Directives; Aircraft Industries a.s. (Type Certificate G60EU previously held by LETECKÉ ZÁVODY a.s. and LET Aeronautical Works) Model L 23 Super Blanik Sailplane
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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; McDonnell Douglas Model DC-8-11, DC-8-12, DC-8-21, DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 Airplanes; Model DC-8-50 Series Airplanes; Model DC-8F-54 and DC-8F-55 Airplanes; Model DC-8-60 Series Airplanes; Model DC-8-60F Series Airplanes; Model DC-8-70 Series Airplanes; and Model DC-8-70F Series Airplanes
We are adopting a new airworthiness directive (AD) for all McDonnell Douglas airplanes identified above. This AD requires repetitive inspections of the lower skin and stringers at stations Xw=408 and Xw408, and corrective actions if necessary. This AD results from reports of cracks in the skins and stringers at the end fasteners common to the stringer end fittings at stations Xw= 408 and Xw408 wing splice joints. We are issuing this AD to detect and correct fatigue cracking in the skins and stringers at the end fasteners common to the stringer end fittings at certain station and wing splice joints, which could result in wing structure that might not sustain limit load, and consequent loss of structural integrity of the wing.
Airworthiness Directives; Saab AB, Saab Aerosystems Model 340A (SAAB/SF340A) and SAAB 340B 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; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) 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 Model 560 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Cessna Model 560 airplanes. That AD currently requires installing new minimum airspeed placards to notify the flightcrew of the proper airspeeds for operating in both normal and icing conditions. That AD also requires revising the airplane flight manual to provide limitations and procedures for operating in icing conditions, for operating with anti-ice systems selected ``on'' independent of icing conditions, and for recognizing and recovering from inadvertent stall. That AD also provides an optional terminating action for the placard installation. This new AD requires the previously optional terminating action. This AD results from an evaluation of in-service airplanes following an accident. The evaluation indicated that some airplanes might have an improperly adjusted stall warning system. We are issuing this AD to prevent an inadvertent stall due to the inadequate stall warning margin provided by an improperly adjusted stall warning system, which could result in loss of controllability of the airplane.
Airworthiness Directives; Rolls-Royce Corporation (RRC) AE 3007A Series Turbofan Engines
The FAA is superseding emergency airworthiness directive (AD) 2008-19-51 that we sent previously to all known U.S. owners and operators of RRC AE 3007A series turbofan engines. That AD requires performing initial and repetitive eddy current inspections (ECIs) on the high-pressure turbine (HPT) stage 2 wheel for cracks. This AD continues to require those same inspections, but revises the compliance schedule for the initial inspection and specifies the affected HPT stage 2 wheels by part number (P/N). This AD results from reports of cracked HPT stage 2 wheels. We are issuing this AD to detect cracks in the HPT stage 2 wheel, which could result in a possible uncontained failure of the HPT stage 2 wheel and damage to the airplane.
Airworthiness Directives; Air Tractor, Inc. Models AT-200, AT-300, AT-400, AT-500, AT-600, and AT-800 Series Airplanes
We are adopting a new airworthiness directive (AD) to supersede AD 2008-11-17, which applies to certain Air Tractor, Inc. Models AT-200, AT-300, AT-400, AT-500, AT-600, and AT-800 series airplanes. AD 2008-11-17 currently requires you to install an overturn skid plate kit or a modification to the overturn skid plate already installed. Since we issued AD 2008-11-17, the manufacturer has notified us that Model AT-401B airplanes also need a modification to the overturn skid plate. Consequently, this AD would retain the actions of AD 2008-11-17 and add the requirement to modify the overturn skid plate installed on Model AT-401B airplanes. We are issuing this AD to prevent the front and rear connections of the overturn skid plate to the airplane from breaking, which could allow foreign debris to enter the cockpit during an airplane overturn. This condition, if not corrected, could lead to pilot injury.
Airworthiness Directives; McDonnell Douglas Model DC-8-11, DC-8-12, DC-8-21, DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 Airplanes; Model DC-8-51, DC-8-52, DC-8-53, and DC-8-55 Airplanes; Model DC-8F-54 and DC-8F-55 Airplanes; Model DC-8-61, DC-8-62, and DC-8-63 Airplanes; Model DC-8-61F, DC-8-62F, and DC-8-63F Airplanes; Model DC-8-71, DC-8-72, and DC-8-73 Airplanes; and Model DC-8-71F, DC-8-72F, and DC-8-73F Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all McDonnell Douglas Model DC-8 airplanes. That AD currently requires, among other things, revision of an existing program of structural inspections. This new AD requires implementation of a revised program of structural inspections of baseline structure to detect and correct fatigue cracking in order to ensure the continued airworthiness of these airplanes as they approach the manufacturer's original fatigue design life goal. This new AD also reduces the inspection threshold for certain principal structural elements. This AD results from a significant number of these airplanes approaching or exceeding the design service goal on which the initial type certification approval was predicated. We are issuing this AD to detect and correct fatigue cracking that could compromise the structural integrity of these airplanes.
Airworthiness Directives; MD Helicopters, Inc. Model MD900 Helicopters
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2008-17-51, which was sent previously to all known U.S. owners and operators of MD Helicopters, Inc. (MDHI) Model MD900 helicopters by individual letters. This AD requires, before further flight, fluorescent magnetic particle inspecting the aft threads of the forward directional control cable (control cable) for a crack and replacing the control cable with an airworthy part if you find a crack. If you do not find a crack, this AD requires that you demagnetize the cable threads until you reach a certain gauss level. This AD also requires visually inspecting the aft cable attach bracket for a crack and for interference with movement of the control cable or for deformation of the aft cable attach bracket. If a crack or interference with movement of the control cable or deformation of the aft cable attach bracket exists, this AD requires replacing the bracket with an airworthy part. This AD also requires modifying the control cable conduit and the rotating cone control rod and identifying the rotating cone control rod with a certain part number. This amendment is prompted by three reports of in-flight failure of the control cable and loss of yaw control resulting in emergency landings and subsequent damage to the helicopter. The actions specified by this AD are intended to prevent loss of yaw control and subsequent loss of control of the helicopter.
