Analysis

The plt took off on rwy 4 & made a climbing left turn for a downwind departure. At aprx 900 ft, there was a partial loss of power to about idle RPM. The plt stated that he switched fuel tanks, applied carburetor heat & pumped the throttle, all to no avail. He turned back to the arpt, but was unable to reach the rwy. The nose gear collapsed during a landing on soft terrain, aprx 150 yards short of rwy 22. An investigation revealed that the inside screen & sponge element of the air intake filter, pn BA-4210, had come loose. Subsequently, the screen & sponge had become lodged in the throat of the carburetor air box & obstructed the airflow to the carburetor. The metal in the screen was found to be non-magnetic. AD 81-15-03 had been issued to correct the filter problem by replacing the aluminum screen with a steel screen.
