Analysis
The acft lost thrust and started a descent at full power during climbout. A forced landing was made in a residential area. Examination of the acft indicated that the prop blades had twisted to low pitch. One blade was twisted 180 degreesat the scene. Torques of less than 50 foot lbs and 25 foot lbs were obtained by FAA. The acft had been used to tow banners and the tach face was marked at 2550 RPM beyond the max-range of this prop and engine combination.
