If you can understand my question, you might be able to help. I'm located some NTSB recommendations on the subject, but it's all blank in the search for the actual ADs. Could it be they were never actually mandated
I found something on the following link :
The following text is relevant :
The NTSB urged that the FAA to require the installation of new LSAS software, known as the Flight Control Computer upgrade (FCC-908) to render the airplane less susceptible to over control. The FAA never required this upgrade, but it was installed in all MD
-11s worldwide nonetheless. The NTSB closed this recommendation as "Acceptable Alternate Action." Well, the change was made to all U.S.-registered MD
-11s, including the one that just crashed at Tokyo. Clearly, upgraded LSAS was not sufficient to cure the MD
-11's shaky and demanding landing characteristics.
Operating a twin over the ocean, you're always one engine failure from a total emergency.
