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:
Production and Airworthiness Approvals, Part Marking, and Miscellaneous Proposals
The FAA is amending its requirements to allow the issuance of export airworthiness approvals for Class II and III products located at facilities outside the United States. The FAA proposed this change in a Notice of Proposed Rulemaking (NPRM) issued on October 5, 2006. That NPRM proposed comprehensive changes to 14 CFR part 21 to standardize production and airworthiness requirements for production approval holders. This final rule expedites the promulgation of a simple and uncontroversial portion of that rulemaking. The FAA intends to issue a separate final rule on other proposals in that NPRM.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would require 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 proposed AD also provides for an optional preventive modification, which would terminate the repetitive inspections. This proposed AD results from a report that the upper frame of the fuselage was severed between stringers S-13L and S-14L at station 747, and the adjacent frame at station 767 had a 1.3-inch-long crack at the same stringer location. We are proposing 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; Bombardier Model DHC-8-400 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; Dassault Model Fan Jet Falcon, Fan Jet Falcon Series C, D, E, F, and G Airplanes; Model Mystere-Falcon 200 Airplanes; and Model Mystere-Falcon 20-C5, 20-D5, 20-E5, and 20-F5 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.

Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F Airplanes
The FAA proposes to revise an existing airworthiness directive (AD) that applies to certain McDonnell Douglas Model DC-10-10, DC-10- 10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, and DC-10-40F airplanes. The existing AD currently requires installing or replacing with improved parts, as applicable, the bonding straps between the metallic frame of the fillet and the wing leading edge ribs, on both the left and right sides of the airplane. This proposed AD would revise the applicability to clarify the identity of the affected airplanes. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to reduce the potential of ignition sources inside fuel tanks in the event of a severe lightning strike, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Airbus Model A330 Airplanes
The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on October 24, 2007 (72 FR 60238). The error resulted in an inadvertent omission of the deadline for submitting comments. This AD applies to all Airbus Model A330 airplanes. This AD requires revising the Procedures and Emergency sections of the Airbus A330 Airplane Flight Manual.
Airworthiness Directives; Boeing Model 707 Airplanes and Model 720 and 720B Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 707 airplanes and Model 720 and 720B series airplanes. This AD requires accomplishing an airplane survey to define the configuration of certain system installations, and repair of any discrepancy found. This AD also requires modifying the fuel system by installing lightning protection for the fuel quantity indication system (FQIS), ground fault relays for the fuel boost pumps, and additional power relays for the center tank fuel pumps and uncommanded on- indication lights at the flight engineer's panel. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent certain failures of the fuel pumps or FQIS, which could result in a potential ignition source inside the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
