Analysis

The plt felt a sudden hard jolt while in cruise flt. The acft assumed a nose low, left wing down attitude which the plt was unable to correct by use of power and control inputs. The acft was at a low altitude due to weather. The acft impacted the water in a left wing down, nose low attitude shortly after the loss of control. After the acft was recovered it was discovered that the left float had separated in flight causing a loss of control. Metallurgical examination revealed pre-existing fatigue cracking of two steel members. The low tensile strength and marginal quality of the steel contributed to the early failure of the fittng.
