NTSB narrative
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.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
