You dont agree the airplane is unstable in the landing environment?
The respective traits are much different in the DC-10 vs the MD-11.The common type rating on the MD-10 and MD-11 is a joke evidenced by the numerous tail strikes and incidents from the the carrier you mention you fly for. They are very different flying airplanes especially in the conditions that were present in Narita.
The technology exists to install on board load sensors to detect and record high landing loads. I find it hard to believe that the landing gears failed just from the damage incurred during the landing accident. I think it was progressive cracks from previous hard landings. No pilot wants to report a hard landing and they pass the airplane on to the next guy who ends upside down on a runway.. Since the same small stabilizer will remain and other landing damage will reoccur in future incidents, it is imperative to monitor the loads from each landing and take appropriate maintenance action.
This is not a slam on the pilots..........it is on the plane from someone who was on the certification Flight Test Team and is a SETP member.
