Airworthiness Directives; Boeing Model 757-200, -200PF, and -200CB Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 757-200, -200PF, and -200CB series airplanes. This proposed AD would require doing an ultrasound inspection for disbonded tear straps not mechanically fastened to the skin, and related investigative and corrective actions, if necessary. This proposed AD results from reports indicating that bonded skin panels may not have been correctly anodized in phosphoric acid before the tear strap doubler was bonded to the skin. We are proposing this AD to detect and correct a weak bond between the skin and tear strap. Such disbonding could reduce the ability of the skin to resist cracks and could adversely affect the structural integrity of the airplane.
Airworthiness Directives; ATR Model ATR42 and ATR72 Airplanes
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:
Airworthiness Directives; Boeing Model 747-200C and -200F Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-200C and -200F series airplanes. This AD requires, among other actions, installing mounting brackets, support angles, and moisture curtains in the main equipment center. This AD results from reports of water contamination in the electrical/ electronic units in the main equipment center. We are issuing this AD to prevent water contamination of the electrical/electronic units, which could cause the electrical/electronic units to malfunction, and as a consequence, could adversely affect the airplane's continued safe flight.
Airworthiness Directives; Boeing Model 777-200, -200LR, -300, and -300ER Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 777-200, -200LR, -300, and -300ER series airplanes. This AD requires doing initial and repetitive inspections for cracking of the elevator actuator fittings, and replacing any cracked fitting with a new fitting. This AD results from a report that a cracked left elevator actuator fitting was found on a Model 777 airplane. We are issuing this AD to detect and correct a cracked actuator fitting, which could detach from the elevator and lead to an unrestrained elevator and an unacceptable flutter condition, which could result in loss of airplane control.
Airworthiness Directives; Boeing Model 757-200, -200CB, and -300 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 757-200, -200CB, and -300 series airplanes. This AD requires repetitive detailed inspections with a borescope for cracks of the intercostal tee clips; or repetitive detailed inspections for cracks of the intercostal tee clips and attachment fasteners at the number 3 and number 4 doorstops of the passenger door cutouts; and related investigative and corrective actions if necessary. This AD also provides an optional terminating action for the repetitive inspections. This AD results from reports of cracked intercostal tee clips at the number 3 and number 4 doorstops of the passenger door cutouts. We are issuing this AD to detect and correct cracking of the tee clips, which could result in additional stress on the adjacent tee clips, surrounding intercostals, edge frame, door structure and doorstops. This additional stress could cause further cracking or breaking of the tee clips, which could result in failure of the door to seal and consequent rapid decompression of the airplane.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires repetitive detailed and high-frequency eddy current inspections for cracking around the heads of the fasteners on the forward fastener row of certain areas of the station (STA) 259.5 circumferential butt splice, and repair if necessary. This AD also requires a preventive modification, which eliminates the need for the repetitive inspections. This AD results from a report that an operator found multiple cracks in the fuselage skin of a Model 737-200 airplane, at the forward fastener row of the STA 259.5 circumferential butt splice between stringers 19 and 24. We are issuing this AD to prevent cracking of the STA 259.5 circumferential butt splice, which could result in loss of structural integrity of the fuselage skin and possible loss of cabin pressure.
Airworthiness Directives; Boeing Model 747-200B, 747-300, and 747-400 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-200B, 747-300, and 747-400 series airplanes. This AD requires an inspection to determine the manufacturer and manufacture date of the oxygen masks in the passenger service units of the outboard and center main deck, the flight attendant service units, flightcrew rest, upper and lower module of the door 5 overhead crew rest, lavatory modules, and miscellaneous ceiling panels, as applicable, and related investigative/corrective actions if necessary. This AD results from a report that several passenger masks with broken in-line flow indicators were found following a mask deployment. We are issuing this AD to prevent the in-line flow indicators of the passenger oxygen masks from fracturing and separating, which could inhibit oxygen flow to the masks and consequently result in exposure of the passengers and cabin attendants to hypoxia following a depressurization event.
Airworthiness Directives; Airbus Model A319, A320, and A321 Series Airplanes
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:
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ, -135ER, -135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all EMBRAER Model EMB-135BJ, -135ER, - 135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The existing AD currently requires reviewing the airplane maintenance records for recent reports of vibration from the tail section or rudder pedals. The existing AD also currently requires repetitively inspecting the skin, attachment fittings, and control rods of rudder II to detect cracking, loose parts, wear, or damage; and related investigative/corrective actions if necessary. This proposed AD would require the existing repetitive inspection to be done with new service information. This proposed AD also would require replacing the locking tab washers on the control rods of the rudder II and installing springs on the hinge assemblies of the rudder II, which would terminate the repetitive inspection requirements. This proposed AD results from reports of rudder vibration due to wear. We are proposing this AD to prevent failure of the rudder control rods, which could result in jamming of the rudder II, and possible structural failure and reduced controllability of the airplane.
Airworthiness Directives; Boeing Model 757 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 757 airplanes. This proposed AD would require repetitive inspections of the anchor tab of the bulkhead seal assemblies of the wing thermal anti-ice (TAI) system for cracks at certain outboard stations of the left and right wings, and corrective action if necessary. This proposed AD also provides optional terminating action for the repetitive inspections. This proposed AD results from reports of cracks found at the anchor tab of the bulkhead seal assemblies of the wing TAI system. In one incident the anchor tab and bulkhead seal assembly had separated because of the cracks. We are proposing this AD to prevent failure of the anchor tab of the bulkhead seal assembly, which in icing conditions could result in insufficient airflow to the wing TAI system, subsequent ice on the wings, and consequent reduced controllability of the airplane.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
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:
Airworthiness Directives; SAAB Model SF340A and Model 340B Airplanes
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:
Airworthiness Directives; EADS SOCATA Model TBM 700 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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:
Airworthiness Directives; Thrush Aircraft, Inc. Model S2R Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Thrush Aircraft, Inc. (Thrush) Model S2R series airplanes. This AD requires you to do repetitive visual inspections of the vertical and horizontal stabilizer attach fitting, attach fitting bolts, and the vertical fin aft spar for cracks or corrosion. This AD also requires immediate replacement of the vertical and horizontal stabilizer attach fittings and attach fitting bolts if cracked or corroded parts are found, and the inspection of the vertical fin aft spar with repair or replacement if cracks or corrosion are found. This AD requires the eventual replacement of the vertical and horizontal stabilizer attach fittings and attach fitting bolts if no corrosion or cracks are found as terminating action for the repetitive inspections. This AD results from reports of cracks in the empennage of Thrush S2R series airplanes. We are issuing this AD to detect and correct these cracks, which could cause the vertical stabilizer to lose structural integrity. This failure could lead to loss of control.
Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30 and DC-10-30F (KC-10A and KDC-10) Airplanes; Model DC-10-40 and DC-10-40F Airplanes; and Model MD-11 and MD-11F Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30 and DC-10-30F (KC-10A and KDC-10) airplanes; Model DC-10-40 and DC-10- 40F airplanes; and Model MD-11 and MD-11F airplanes. This AD requires, for certain airplanes, modifying the thrust reverser command wiring of the number 2 engine. For certain other airplanes, this AD requires modifying the thrust reverser system wiring from the flight compartment to engines 1, 2, and 3 thrust reversers. This AD also requires installing thrust reverser locking systems on certain airplanes. This AD results from a determination that the thrust reverser systems on these McDonnell Douglas airplanes do not adequately preclude unwanted deployment of a thrust reverser. We are issuing this AD to prevent an unwanted deployment of a thrust reverser during flight, which could result in reduced controllability of the airplane.
Notice of Opportunity To Participate, Criteria Requirements and Application Procedure for Participation in the Military Airport Program (MAP)
In anticipation of congress enacting an extension of the Airport Improvement Program (AIP) the FAA is publishing this annual notice. This notice announces the criteria, application procedures, and schedule to be applied by the Secretary of Transportation in designating or redesignating, and funding capital development annually for up to 15 current (joint-use) or former military airports seeking designation or redesignation to participate in the MAP. While FAA currently has continuing authority to designate or redesignate airports, FAA does not have authority to issue grants for fiscal year 2008 MAP, and will not have authority until Congress enacts legislation enabling FAA to issue grants. The MAP allows the Secretary to designate current (joint-use) or former military airports to receive grants from the Airport Improvement Program (AIP). The Secretary is authorized to designate an airport (other than an airport designated before August 24, 1994) only if: (1) The airport is a former military installation closed or realigned under the Title 10 U.S.C. Sec. 2687 (announcement of closures of large Department of Defense installations after September 30, 1977), or under Section 201 or 2905 of the Defense Authorization Amendments and Base Closure and Realignment Acts; or (2) The airport is a military installation with both military and civil aircraft operations. The Secretary shall consider for designation only those current or former military airports, at least partly converted to civilian airports as part of the national air transportation system, that will reduce delays at airports with more than 20,000 hours of annual delays in commercial passenger aircraft takeoffs and landings, or will enhance airport and air traffic control system capacity in metropolitan areas, or reduce current and projected flight delays (49 U.S.C. 47118(c)).
