Analysis narrative
The pilot reported that, shortly after takeoff in a float-equipped airplane, he heard rustling noises coming from the aft cargo section of the airplane. The pilot glanced behind him to identify the source of the noises and, as he looked forward again, the airplane impacted the water resulting in substantial damage to the wings and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
