Airworthiness Directive · Amendment 39-14328 · Honeywell Flight Management System (FMS) One Million Word (1M or 700K) Data Bases (9104 Cycle or Earlier), as Installed in, but Not Limited to, McDonnell Douglas Model MD-11 and MD-11F Airplanes, Boeing Model 747-400 Series Airplanes, and Boeing Model 757 and 767 Airplanes
Honeywell Flight Management System (FMS) One Million Word (1M or 700K) Data Bases (9104 Cycle or Earlier), as Installed in, but Not Limited to, McDonnell Douglas Model MD-11 and MD-11F Airplanes, Boeing Model 747-400 Series Airplanes, and Boeing Model 757 and 767 Airplanes
This action applies to Honeywell Flight Management System (FMS) one million word (1M or 700K) data bases (9104 cycle or earlier), as installed in, but not limited to, McDonnell Douglas Model MD-11 and MD-11F airplanes, and Boeing Model 747-400 series airplanes, Model 757-200, -200PF, -200CB, and -300 series airplanes, and Model 767-200, -300, -300F, and -400ER series airplanes, certificated in any category.
The FAA is rescinding an existing airworthiness directive (AD) that applies to Honeywell FMS one million word (1M or 700K) data bases (9104 cycle or earlier) as installed in, but not limited to McDonnell Douglas Model MD-11 and MD-11F airplanes, Boeing Model 747-400 series airplanes, and Boeing Model 757 and 767 airplanes. That AD requires a revision to the FAA-approved Airplane Flight Manual (AFM) and installation of a placard to prohibit the use of Nondirectional Beacon (NDB) approaches for landing. That AD was prompted by an anomaly in the Honeywell FMS one million word (1M or 700K) data bases (9104 cycle or earlier). We issued that AD to prevent an airplane deviating from the published approach to the runway, which could lead to premature ground contact before reaching the runway. Since we issued that AD, we have determined that the Honeywell FMS one million word (1M or 700K) databases (9104 cycle or earlier) no longer exist on any of the affected airplanes.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
