  1. This is going to be interesting final report. This doesn't go into detail on how the spar was damaged and in what mode and direction the damage occurred. Are they implying that "hard landing" damaged a wing spar without collapsing the gear? That would be hard for me to believe. Also, the article is titled "Prop / Jet / Rotor-Blast/ Suction." Other than flipping the plane over, what could that have to do with this spar damage?

  2. Yep ... Hard landing on the twin cessnas normally collapses the gear.
