Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB- 135BJ airplanes. This proposed AD would require modifying the forward and aft auxiliary fuel tanks. This proposed AD results from a report of sparks due to chafing between the harnesses of the forward and aft auxiliary fuel tanks, between certain harnesses attached to the aircraft structure, or between certain harnesses attached to certain mechanical components. We are proposing this AD to prevent a potential ignition source inside a fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion.
Airworthiness Directives; Airbus Model A330 and A340 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A330 and A340 airplanes. This proposed AD would require revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness by incorporating new and revised certification maintenance requirements (CMRs). This proposed AD results from the manufacturer's determination that additional and revised CMRs are necessary in order to ensure continued operational safety of the affected airplanes. We are proposing this AD to prevent safety-significant latent failures that would, in combination with one or more other specific failures or events, result in a hazardous or catastrophic failure condition.
Airworthiness Directives; Fokker Model F27 Mark 100, 200, 300, 400, 500, 600, and 700 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F27 Mark 100, 200, 300, 400, 500, 600, and 700 airplanes. This AD requires revising the Limitations section of the airplane flight manual regarding the use of continuous ignition, fuel filter heating, and resetting circuit breakers during flight in certain conditions such as icing. This AD results from reports of power loss on one or both engines in icing conditions. We are issuing this AD to advise the flightcrew that continuous ignition will not reduce the probability of power loss, and what action they must take to avoid this hazard. Loss of power in one or more engines during flight, if not prevented, could result in loss of control of the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145XR Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-145XR airplanes. This AD requires replacement of certain segments of the passenger seat tracks with new, improved seat tracks. This AD results from instances where the shear plungers of the passenger seat legs were not adequately fastened. We are issuing this AD to prevent inadequate fastening of the seat leg shear plungers, which could result in failure of the passenger seat tracks during emergency landing conditions and consequent injury to passengers.
Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes Equipped with Rolls-Royce Engines
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes equipped with Rolls-Royce engines. This AD requires repetitive inspections to detect cracks of the outer V-blades of the thrust reverser, and corrective action if necessary. This AD also provides for optional terminating action for the repetitive inspections. This AD results from reports of cracked outer V-blades in the thrust reversers. We are issuing this AD to prevent separation of a thrust reverser from the airplane during normal reverse thrust or during a refused takeoff, which could result in impact damage to other airplane areas. If a thrust reverser separates from the airplane during a refused takeoff, the engine could produce forward thrust, resulting in unexpected thrust asymmetry and a possible runway excursion.
Standard Instrument Approach Procedures, Weather Takeoff Minimums; Miscellaneous Amendments
This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and/or Weather Takeoff Minimums for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
Operating Limitations at New York LaGuardia Airport; Notice of Order
On September 11, 2006, the FAA issued a proposed order, which requested written views on the FAA's tentative determination to place temporary limitations on flight operations at New York's LaGuardia Airport (LaGuardia). The temporary limits are intended to prevent the congestion-related delays that would otherwise occur during the interval between the expiration of the High Density Rule and the effective date of a long-term regulation. In response to comments, the FAA is issuing a final order (the Order) that adopts the proposed limitations with some modifications. The limitations will permit 75 scheduled and six unscheduled operations per hour between 6 a.m. through 9:59 p.m., Eastern time, Monday through Friday and from 12 noon through 9:59 p.m., Eastern Time, on Sundays.
