Résumé

Données préliminaires issues de la notification des autorités des Etats-Unis :

N790AM, an AS350B3, was patrolling southern AZ looking for scouts and dropping agents off. The pilot made a landing that he thought was firm but not hard. They refueled, conducted a walk around, and returned to Tucson AB. Maintenance subsequently found the tailboom to be wrinkled and the K flex on the short shaft delaminated.
