Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2012-05- 03, which applies to certain The Boeing Company Model 747-100, 747- 100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. AD 2012-05-03 currently requires modifying the fluid drain path in the leading edge area of the wing. Since we issued AD 2012-05-03, Boeing has informed us that it did not provide work instructions to seal two of the drainage holes in the wing leading edge area. This proposed AD would require additional work to seal those drainage holes in the wing access panels. We are proposing this AD to address the unsafe condition on these products.
Amendment of Class C Airspace; Little Rock, AR
This action modifies the Little Rock, AR, Class C airspace area by amending the legal description to update the current airport name and updated airport reference point (ARP) information to match the FAA's aeronautical database and charted information. Additionally, exclusion language is added to the legal description to ensure flight safety and address any potential for confusion where the Class C and restricted area R-2403B airspace areas overlap. This action does not change the boundaries, altitudes, or operating requirements of the Class C airspace area.
