This from the C180 crash.
“It is most likely that the bracing wire became disconnected shortly after take-off, when the unsecured clevis pin fell out. The looseness that existed at the float attachment points allowed the now-unbraced floats to twist out of alignment. The subsequent increase in parasitic and induced drag initiated a loss of airspeed. Although the exact airspeed trend was not observed or recorded, it progressed to the onset of an aerodynamic stall. Subsequent to the unfamiliar sound, this progression was indicated by the activation of the stall warning horn, the uncommanded left bank, and the ineffective flight controls. The stall occurred at an altitude of approximately 200 feet above the level of the tree tops on the surrounding terrain, and a successful recovery was not possible.”
Except for the 200 ft height it could be describing the QLD crash.
