They strengthened the horizontal and vertical, but there are no tell-tale signs of any elevator problems, other than the plastic trim tabs and maybe the outer hinge. The mechanics would ensure the mods are complete on the current airplanes.
Also did a stress analysis of the torque tube and if I did it right, for a 9 g turn at Reno, it's only 5 kpsi. Yield for 2024-T3 is around 45 kpsi, so fatigue or outright failure of the tube is low probability. That leaves the attachment analysis. Contacted a restorer in Texas and will try to talk him into drilling off the D spar of a damaged elevator to get the attachment details. Or, if anybody has the blueprints, or details, that would be better.
