IUKA, MS, USA
N7136R
PIPER PA-28-140
ON INITIAL CLIMB FROM TAKE-OFF, A PARTIAL POWER LOSS OCCURRED. CARB HEAT WAS SELECTED BUT PWR REMAINED AT A LEVEL TOO LOW TO SUSTAIN ALTITUDE AND A FORCED LANDING WAS EFFECTED IN ROUGH, WOODED TERRAIN. INVESTIGATION REVEALED NO DISCREPANCIES IN THE FUEL OR IGNITION SYSTEMS. THE ALTERNATE DUCT FOR INDUCTION AIR (CARB HEAT ON) WAS FOUND TO BE ALMOST TOTALLY BLOCKED BY A MUD DAUBER NEST. THE NORMAL INDUCTION AIR DUCT AND FILTER WERE IMPACT DAMAGED AND EVIDENCE OF BLOCKAGE COULD NOT BE CONCLUSIVELY DETERMINED. THE AIRCRAFT ANNUAL INSPECTION WAS 5 MONTHS OVERDUE.
