Boeing Model 737-600, -700, -700C, -800, and -900 Series Airplanes; Model 747 Series Airplanes; and Model 757 Series Airplanes
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2002-24-51 that was sent previously to all known U.S. owners and operators of the airplane models described previously by individual notices. This AD requires revising the Airplane Flight Manual to require the flightcrew to maintain certain minimum fuel levels in the center fuel tanks and, for certain airplanes, to prohibit the use of the horizontal stabilizer fuel tank and the certain center auxiliary fuel tanks. This action is prompted by reports indicating that two fuel tank pumps showed evidence of extreme localized overheating of parts in the priming and vapor pump section of the fuel pump; such overheating provides an ignition source in the fuel tank during dry running of the pump, which could result in fire/explosion of the fuel tank. The actions specified by this AD are intended to require the flightcrew to maintain certain minimum fuel levels in the center fuel tanks and, for certain airplanes and, for certain airplanes to prohibit the use of the horizontal stabilizer fuel tank and certain center auxiliary fuel tanks.

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2002-24-52 that was sent previously to all known U.S. owners and operators of all Boeing Model 747-400, -400D, and -400F series airplanes by individual notices. This AD continues to require revising the Airplane Flight Manual to require the flightcrew to maintain certain minimum fuel levels in the center fuel tanks, and to prohibit the use of the horizontal stabilizer fuel tank. This AD also removes the reference to placards that was specified in the operating limitations required by another AD. This action is prompted by reports indicating that two fuel pumps showed evidence of extreme localized overheating of parts in the priming and vapor pump section of the fuel pump. Such overheating provides an ignition source in the fuel tank during dry running of the pump, which could result in fire/explosion of the fuel tank. The actions specified by this AD are intended to require the flightcrew to maintain certain minimum fuel levels in the center fuel tanks, and to prohibit the use of the horizontal stabilizer fuel tank.

This amendment adopts a new airworthiness directive (AD) that applies to all Univair Aircraft Corporation (Univair) Models Alon A-2 and A2-A; ERCO 415-C, 415-CD, 415-D, 415-E, and 415-G; Forney F-1 and F-1A, and Mooney M10 airplanes. This AD requires you to repetitively inspect the wing center section for evidence of corrosion through the installation of inspection openings, through the use of a specified scope and light source, or through the removal of the outer wing panels. This AD also requires you to repair or replace any parts where corrosion or corrosion damage is found, install cover plates if inspection openings were made, and send inspection results to Federal Aviation Administration (FAA). This AD is the result of several reports of corrosion being found throughout the wing center section structure. The actions specified by this AD are intended to detect and correct corrosion in the wing center section which could result in failure of the wing center section structure during flight. Such failure could lead to loss of control of the airplane.

Air Tractor, Inc. Models AT-502, AT-502A, AT-502B, and AT-503A Airplanes
This amendment supersedes Airworthiness Directive (AD) 2002- 11-03, which applies to certain Air Tractor, Inc. (Air Tractor) Models AT-502, AT-502A, AT-502B, and AT-503A airplanes. AD 2002-11-03 lowered the safe life for the wing lower spar cap and further reduced the safe life for airplanes that incorporate or have incorporated Marburger Enterprises, Inc. winglets. AD 2002-11-03 also currently requires you to eddy-current inspect the wing lower spar cap immediately prior to the replacement/modification to detect and correct any crack in a bolthole before it extends to the modified center section of the wing and report the results of this inspection to the Federal Aviation Administration (FAA). Field inspections on the affected airplanes have revealed wings with cracks below the currently established safe life. This AD would further reduce the safe life of the Models AT502, AT- 502B, and AT-503A airplanes and would add airplanes recently manufactured to the Applicability of the AD. The actions specified by this AD are intended to prevent fatigue cracks from occurring in the wing lower spar cap before the established safe life is reached. Fatigue cracks in the wing lower spar cap, if not detected and corrected, could result in the wing separating from the airplane during flight.
