Is there anything in modern transport aircraft that records peak accelerations for various parts of the aircraft, in order to flag the aircraft for inspection or other action if certain design limits are exceeded? I'm thinking mainly of hard landings or extreme turbulence. Clearly, pilots have a good feel for what's not a problem and what might be a problem, but a documented record would make it easier to draw the line unambiguously.
Perhaps those extra boxes that the airlines use in addition to black boxes (I can't remember their names) might record this type of information? Also, if they do record the information, and if it is archived and integrated over time, it would be possible to calculate total stress and fatigue risk for parts of the airframe over its lifetime, perhaps avoiding unnecessary maintenance and also forcing needed maintenance if an aircraft has fortuitously had a large number of rough rides.
