Airworthiness Directives; Airbus Model A330 Airplanes and Model A340-200 and -300 Series Airplanes

Tue, Jul 8 2008 11:00:00 GMT

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330 airplanes and Model A340200 and 300 series airplanes. This AD requires revising the airplane flight manual (AFM) to prohibit the flightcrew from performing CAT 2 and CAT 3 automatic landings and rollouts at certain airports. This AD also provides an optional terminating action for the AFM revision. This AD results from data showing that the magnetic variation table installed in certain Honeywell and Northrop Grumman air data inertial reference units (ADIRUs) is obsolete at certain airports. We are issuing this AD to prevent the airplane from departing the runway during a CAT 2 or CAT 3 automatic landing or rollout, due to differences between actual magnetic variation and the values in the ADIRU magnetic variation tables.

Airworthiness Directives; APEX Aircraft Model CAP 10B Airplanes

Tue, Jul 8 2008 11:00:00 GMT

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 [[Page 38890]]
another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

It has been determined that the currently used values for Arms of front and rear fuel tanks, and luggage compartment from the CAP 10B Airplane Flight Manuals (AFM), must be rectified.

If left uncorrected, these weight and balance data could lead to erroneous determination of the location of the Center of Gravity (CG) and possibly cause operation with the CG outside the approved limits which may result in control difficulty.

We are issuing this AD to require actions to correct the unsafe condition on these products.

Airworthiness Directives; ATR Model ATR42 Airplanes and Model ATR72-101, -102, -201, -202, -211, and -212 Airplanes

Tue, Jul 8 2008 11:00:00 GMT

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:

It has been found on inservice aircraft that some aileron tab bellcrank assemblies were not in accordance with the definition drawings.

The main item concerned is the retainer Part Number S2711004620000, which has been manufactured with a hole larger than it should be, or redrilled out of limits.

The function of the retainer is to maintain the spacer in position in case of rupture or loss of the bolt which links the tab control rod to the bellcrank assembly. If the diameter of the retainer hole is out of limit, the retainer function is lost and failsafe installation is no longer ensured. This condition, if not corrected, could lead to loss of the aileron tab bellcra

Airworthiness Directives; Boeing Model 737-100, -200, -200C, - 300, -400, and -500 Series Airplanes

Tue, Jul 8 2008 11:00:00 GMT

We are adopting a new airworthiness directive (AD) for certain Boeing Model 737100, 200, 200C, 300, 400, and 500 series
airplanes. This AD requires various repetitive inspections for cracking of the upper frame to side frame splice of the fuselage, and other specified and corrective actions if necessary. This AD also provides for an optional preventive modification, which terminates the repetitive inspections. This AD results from a report that the upper frame of the fuselage was severed between stringers S13L and S14L at station 747, and the adjacent frame at station 767 had a 1.3inchlong crack at the same stringer location. We are issuing this AD to detect and correct fatigue cracking of the upper frame to side frame splice of the fuselage, which could result in reduced structural integrity of the frame and adjacent lap joint. This reduced structural integrity can increase loading in the fuselage skin, which will accelerate skin crack growth and result in decompression of the airplane.

Airworthiness Directives; Boeing Model 737-300 and -400 Series Airplanes

Tue, Jul 8 2008 11:00:00 GMT

We are adopting a new airworthiness directive (AD) for certain Boeing Model 737300 and 400 series airplanes. This AD requires testing and inspecting a certain web panel of the main wheel well pressure deck to determine the material type and thickness; and related investigative and corrective actions if necessary. This AD results from several reports indicating that cracks ranging from 0.8 to 8.0 inches long were found on a certain web panel of the main wheel well pressure deck. We are issuing this AD to prevent fatigue cracking in the web panel of the main wheel well pressure deck, which could result in venting and consequent decompression of the airplane.

Airworthiness Directives; Boeing Model 777-200, -200LR, -300, and -300ER Series Airplanes Approved for Extended-Range

Tue, Jul 8 2008 11:00:00 GMT

We are adopting a new airworthiness directive (AD) for certain Boeing Model 777200, 200LR, 300, and 300ER series airplanes. This AD requires a onetime inspection to determine the part number of the cargo compartment fire suppression filter/regulator. This AD also requires, for certain airplanes, a revision of the ``Maximum Diversion Time in Minutes'' for ETOPS operation specified in the Operations Specifications. For certain airplanes, this AD also provides for optional replacement of the cargo compartment fire suppression filter/ regulator, which would allow revision of the ``Maximum Diversion Time in Minutes'' for ETOPS operation specified in the Operations Specifications to restore the airplane's full ETOPS capability. This AD results from a report that the filter/regulator installed in the cargo fire suppression system did not meter the Halon for the certified duration during ETOPS flight tests. We are issuing this AD to prevent ETOPS operation with insufficient cargo fire suppression capabi

Airworthiness Directives; Dassault Model Falcon 2000 Airplanes

Tue, Jul 8 2008 11:00:00 GMT

In service events have shown that, after implementation of Dassault Aviation SB (service bulletin) F2000133 and F2000166, a risk of engine cowlings separation from the airplane still exists, and may cause potential damages to the engine itself and to the horizontal stabilizer.

It is suspected that onground improper latching may lead to a radial deformation of engine cowlings in flight and to their eventual escape out of their locking devices. This situation may represent a hazard to the aircraft propulsive system and/or its structural integrity.
* * * * *
We are issuing this AD to require actions to correct the unsafe condition on these products.

Airworthiness Directives; Gulfstream Aerospace LP Model Astra SPX, 1125 Westwind Astra, and Gulfstream 100 Airplanes

Tue, Jul 8 2008 11:00:00 GMT

Two of the fasteners used to attach the ``scissors'' to the horizontal and the vertical stabilizers were found broken during routine maintenance. The highest loads on the ``scissors'' occur when using high reverse thrust. Therefore, the reverse thrust must be limited to idle in order to keep the loads at a sufficiently low level to preclude any structural problem. * * *
Failure of the attachment fasteners could result in possible inflight loss of a horizontal or vertical stabilizer and consequent loss of control of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.

Airworthiness Directives; Lockheed Model 1329 Series Airplanes

Tue, Jul 8 2008 11:00:00 GMT

We are adopting a new airworthiness directive (AD) for certain Lockheed Model 1329 series airplanes. This AD requires determining the part number on the steering cylinder assembly for the nose landing gear (NLG), determining the total flight cycles accumulated on the NLG steering cylinder assembly, repetitively replacing the assembly, inspecting for missing tow turning limit markings, and performing corrective actions if necessary. This AD results from reports of numerous failures of the NLG steering cylinder. We are issuing this AD to prevent the loss of hydraulic pressure and steering control.

Airworthiness Directives; McDonnell Douglas Model DC-9-81 (MD- 81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87),

Tue, Jul 8 2008 11:00:00 GMT

We are adopting a new airworthiness directive (AD) for all McDonnell Douglas Model DC981 (MD81), DC982 (MD82), DC983 (MD 83), DC987 (MD87), and MD88 airplanes. This AD requires repetitive inspections for cracking of the overwing frames from stations 845 to 905 (MD87 stations 731 to 791), left and right sides, and corrective actions if necessary. This AD results from reports of cracked overwing frames. We are issuing this AD to detect and correct such cracking, which could sever the frame, increase the loading of adjacent frames, and result in damage to adjacent structure and loss of overall structural integrity of the airplane.

Airworthiness Directives; Air Tractor, Inc., Models AT-402, AT- 402A, and AT-402B Airplanes

Tue, Jul 8 2008 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for certain Air Tractor, Inc., (Air Tractor) Models AT402, AT402A, and AT402B airplanes. This proposed AD would require you to repetitively visually inspect the rudder and vertical fin hinge attaching structure for loose fasteners and inspect the rudder or vertical fin skins, spars, hinges or brackets for cracks and/or corrosion. The AD would also require you to replace any damaged parts found as a result of the inspections and install an external doubler at the upper rudder hinge. Installation of the external doubler at the upper rudder hinge is terminating action for the repetitive inspection requirements. This proposed AD results from a report of a Model AT402 airplane with a loose upper rudder hinge caused by fatigue. We are proposing this AD to detect and correct loose fasteners; any cracks in the rudder or vertical fin skins, spars, hinges or brackets; or corrosion of the rudder and vertical fin hinge attaching structure. Hinge failur

Airworthiness Directives; EADS SOCATA Model TBM 700 Airplanes

Tue, Jul 8 2008 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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:

It has been discovered that a risk of mechanical interference exists in the movement of the emergency landing gear bypass selector, due to an insufficient functional gap between a floor panel attachment lug and the landing gear control button.

This condition, if not corrected, causes mechanical interference which could result in a situation where, during emergency
procedures, the landing gear cannot be extended.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

Airworthiness Directives; Empresa Brasileira de Aeronautica S. A. (EMBRAER) Models EMB-110P1 and EMB-110P2 Airplanes

Tue, Jul 8 2008 11:00:00 GMT

We are revising an earlier supplemental NPRM for the products listed above. This proposed 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:

It has been found cases of corrosion at the regions of Wingsto Fuselage attachments, Vertical Stabilizer to Fuselage attachments, Rib 1 Halfwing and Passenger Seat Tracks. Such corrosion may lead to subsequent cracking of the affected parts, compromising the aircraft structural integrity, which may in turn lead to structural failure and/or loss of some control surface.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
