## Discrepancy

ABNORMAL READING ON COPILOT'S ALTIMETER (DIFFERENCE = 1 THOUSAND FEET).  AFTER LANDING, STALL SYSTEM WAS CHECKED AND FOUND ALL 20 STATIC LINES IN AIRCRAFT EITHER PARTIALLY PLUGGED OR, IN THIS CASE, ONE LINE ALMOST COMPLETELY PLUGGED.  FOUND APPROXIMATELY 50 BOUGAINVILLEA LEAVES IN SYSTEM ALL CURLED UP AND WELL UP INTO THE LINES.  ANOTHER AIRCRAFT FOUND WITH SAME LEAVES IN IT.  THE LEAVES ARE PULLED INTO THE SYSTEM BY A SMALL WASP.  THERE WAS YELLOW POLLEN AROUND THE STATIC PORT HOLES.  IN SMALLER AIRCRAFT, THIS COULD BE A PROBLEM IN THE PITOT HEADS.  SUBMITTER STATED ALL PILOTS SHOULD BE NOTIFIED OF THE PROBLEM ESPECIALLY IN SOUTHERN CALIFORNIA AREA.
