This AD applies to The Boeing Company 747-100 Series, 747-100B Series, 747-100B SUD Series, 747-200B Series, 747-200C Series, 747-200F Series, 747-300 Series, 747SP Series.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-100, -200, -300, and SP series airplanes, that requires revising the Airplane Flight Manual (AFM) to prohibit the use of the autoland function. This amendment also requires installation of a diode and a marker on certain shelves and making wiring changes to the flight mode annunciator of the autopilot/flight director system, which terminates the requirements for the AFM limitation. This amendment is prompted by a report that the flightcrew was unaware of the configuration of the autoland system during landing. The actions specified by this AD are intended to ensure flightcrew awareness of the configuration of the autoland system in the event of a change from fail-operational to fail-passive mode.
