Bede Aircraft BD-5B
THE ACFT CRASHED SHORT OF THE RWY DURING AN ATTEMPTED LANDING. THERE WERE SOME CONFUSING AND GARBLED TRANSMISSIONS AND SOME MISTAKEN INSTRUCTIONS FROM THE TOWER DURING THE PROBLEM EXPERIENCED BY THE ACCIDENT PLT. THIS PLT DID NOT MAKE IT CLEAR THAT HE HAD AN EMERGENCY BUT HE DID ASK FOR IMMEDIATE LANDING DUE TO A PROBLEM. HIS ENGINE WAS HEARD OPERATING AT ALTERNATING HIGH AND LOW LEVELS. HIS ACFT HAD A HISTORY OF OVERHEATING AND IT ALSO HAD AN IMPROPER PROPELLER INSTALLED. A NEW PROPELLER WAS ON ORDER. ACCORDING TO GREAT AMERICAN PROPELLER CO, THE PROPELLER INSTALLED ON THE ACFT DID NOT HAVEENOUGH BLADE AREA FOR THE AIRFRAME/ENGINE COMBINATION. THIS COMBINATION COULD CAUSE ENFORCED MODERATE APPLICATION OF THROTTLE AND AT FULL THROTTLE AND LOW AIRSPEEDS COULD RESULT IN EXCESSIVE RPM AND PROBABLE CAVITATION AND LOSS OF THRUST.
