Airworthiness Directives; Airbus Model A330 Airplanes

Mon, Dec 3 2007 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 discovered that a batch of sleeves and pins of the RollsRoyce Trent 700 Thrust Reverser Unit (TRU) hinge n[deg] [number] 5 has not been subjected to the correct precipitation hardening.

This production quality issue, if not corrected, can lead to the complete failure of the hinge n[deg] 5the remaining hinges may not sustain ultimate loadresulting in the worst case to the TRU release from the pylon, which constitutes an unsafe condition.

The degradation of the mechanical specifications of these parts puts into question the current design life goal of these parts. * * *
The unsafe condition is possible detachment of the thrust reverser unit from the airpla

product. The MCAI describes the unsafe condition as:

This Airworthiness Directive (AD) is prompted by the discovery of cracks on L13 BLANIK sailplanes in zones where the forward and aft control sticks are attached to the connecting rod, designated as ``control bridge'' in the relevant Illustrated Parts Catalogues (IPC). If left uncorrected, cracks could propagate and lead to failure of the connecting rod with subsequent loss of control of the sailplane.
We are issuing this AD to require actions to correct the unsafe condition on these products.

Airworthiness Directives; Fokker Model F27 Mark 050 Airplanes

Mon, Dec 3 2007 11:00:00 GMT

During scheduled MRB (maintenance review board) midlife Xray inspections of Fokker 50 (F27 Mark 050) engine mount frames, severe internal corrosion of the tubes was discovered. In some locations, the depth of the corrosion spots appeared to be more than 50 percent of material thickness. * * * This condition, if not corrected, could ultimately lead to failure of the engine mounting frame in cases where multiple tubes are severely affected. * * *
This AD requires actions that are intended to address the unsafe condition described in the MCAI.

Airworthiness Directives; Piaggio Aero Industries S.p.A. Model P- 180 Airplanes

Mon, Dec 3 2007 11:00:00 GMT

One P 180 aircraft experienced a jamming of its longitudinal flight control cables. Investigations revealed that its fuselage drain holes were plugged, and water was trapped in the lower fuselage.

As a consequence of plugged drain holes, water can accumulate and freeze when the aircraft reaches and holds altitudes where temperature is below the freezing point. If not corrected this may cause the loss of control of the airplane.
We are issuing this AD to require actions to correct the unsafe condition on these products.

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

Mon, Dec 3 2007 11:00:00 GMT

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A330 series airplanes and Model A340200 and 300 series airplanes. This proposed AD would require 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 proposed 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 proposing 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; Boeing Model 737-600, -700, -700C, - 800, and -900 Series Airplanes

Mon, Dec 3 2007 11:00:00 GMT

The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 737600, 700, 700C, 800, and 900 series airplanes. This proposed AD would require repetitive inspections for any cracking of or damage to the left side and right side flight deck No. 2, No. 4, and No. 5 windows, as necessary, and corrective actions if necessary. This proposed AD results from reports of inflight departure and separation of the flight deck windows. We are proposing this AD to detect and correct cracking in the vinyl interlayer or damage to the structural inner glass panes of the flight deck No. 2, No. 4, and No. 5 windows, which could result in loss of a window and rapid loss of cabin pressure. Loss of cabin pressure could cause crew communication difficulties or crew incapacitation.

Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes

Mon, Dec 3 2007 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for the [[Page 67871]]
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:

Bombardier Aerospace has completed a system safety review of the CL6002B19 aircraft fuel system * * *.

The assessment showed that sealant has not been applied to bolts on the collector fuel tanks or the transfer ejector fuel pumps. Lack of sealant on the abovenoted locations, if not corrected, could result in arcing and potential ignition source inside the fuel tank during lightning strikes and consequent fuel tank explosion. * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
