What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(.19) On December 18, 1999, at about 0917 central standard time, a swertfeger velocity 173 elite, experimental homebuilt airplane, N627KB, registered to a private owner, operating as a 14 CFR part 91 personal flight, crashed while on approach to Murfreesboro municipal airport, (mbt), Murfreesboro, Tennessee. Visual meteorological conditions prevailed and no flight plan was filed. The airplane sustained substantial damage. The private pilot was fatally injured. The flight originated from decatur, Alabama, (dcu) at an undetermined time. According to a witness, the accident pilot departed dcu following another pilot. He had talked to the pilots while taxiing out for takeoff at dcu over the airplane radio and determined that they were all going to the same breakfast fly-in. He caught up with the other two airplanes while en route to mbt. Upon arrival at mbt, N627KB entered traffic for runway 18, and he was located behind him. Someone announced on the UNICOM frequency that they were changing the landing runway to runway 36. He broke out of the current traffic pattern, entered downwind for runway 36, landed, and taxied to the parking ramp. A short time later, he heard N627KB state that his engine was out. He turned his airplane around and observed N627KB disappear behind the trees. (-23)on Saturday, December 18, 1999 at approx. 8:18 am local time, an experimental velocity 173 elite a/c built and flown byprivacy data omitted experienced an engine failure while on approach to runway 36 at the Murfreesboro, Tennessee airport. The a/c, N627KB, crashed near a residence at 1602 leaf avenue, Murfreesboro, Tennessee, 37130.privacy data omittedThe only occupant, suffered fatal injuries, and the a/c sustained substantial damage in the accident. (.4)the pilot was on approach for landing when the airplane exp erienced a total loss of engine power, and crashed during a forced landing. Examination of the airframe and engine assembly revealed no evidence of a precrash mechanical failure or malfunction. Visual inspection of the spark plugs revealed very black and sooty. Fuel was present in the flow divider but was not present in the line between the fuel servo and flow divider. The servo fuel injector was removed and examined. The fuel diaphragm had not been replaced. The servo fuel injector was placed in a test bench and a functional test performed. Fuel was pouring out of the venturi causing erratic air flow through the regulator and erratic air flow. The air cover and diaphragm was removed to determine the source of the fuel leak. The fuel diaphragm stem was bent. The center body was removed with the fuel diaphragm attached to the center body bellows. The bottom calibration nut was removed from the fuel diaphragm stem. The fuel diaphragm was removed from the bellows and a leakage check was performed. The bellows was split and air was leaking through the bellows. Appropriate ad's and sb's had not been complied with resulting in an in-flight power loss due to an over rich condition.
As the FAA filed it
(.19) ON DECEMBER 18, 1999, AT ABOUT 0917 CENTRAL STANDARD TIME, A SWERTFEGER VELOCITY 173 ELITE, EXPERIMENTAL HOMEBUILT AIRPLANE, N627KB, REGISTERED TO A PRIVATE OWNER, OPERATING AS A 14 CFR PART 91 PERSONAL FLIGHT, CRASHED WHILE ON APPROACH TO MURFREESBORO MUNICIPAL AIRPORT, (MBT), MURFREESBORO, TENNESSEE. VISUAL METEOROLOGICAL CONDITIONS PREVAILED AND NO FLIGHT PLAN WAS FILED. THE AIRPLANE SUSTAINED SUBSTANTIAL DAMAGE. THE PRIVATE PILOT WAS FATALLY INJURED. THE FLIGHT ORIGINATED FROM DECATUR, ALABAMA, (DCU) AT AN UNDETERMINED TIME. ACCORDING TO A WITNESS, THE ACCIDENT PILOT DEPARTED DCU FOLLOWING ANOTHER PILOT. HE HAD TALKED TO THE PILOTS WHILE TAXIING OUT FOR TAKEOFF AT DCU OVER THE AIRPLANE RADIO AND DETERMINED THAT THEY WERE ALL GOING TO THE SAME BREAKFAST FLY-IN. HE CAUGHT UP WITH THE OTHER TWO AIRPLANES WHILE EN ROUTE TO MBT. UPON ARRIVAL AT MBT, N627KB ENTERED TRAFFIC FOR RUNWAY 18, AND HE WAS LOCATED BEHIND HIM. SOMEONE ANNOUNCED ON THE UNICOM FREQUENCY THAT THEY WERE CHANGING THE LANDING RUNWAY TO RUNWAY 36. HE BROKE OUT OF THE CURRENT TRAFFIC PATTERN, ENTERED DOWNWIND FOR RUNWAY 36, LANDED, AND TAXIED TO THE PARKING RAMP. A SHORT TIME LATER, HE HEARD N627KB STATE THAT HIS ENGINE WAS OUT. HE TURNED HIS AIRPLANE AROUND AND OBSERVED N627KB DISAPPEAR BEHIND THE TREES. (-23)ON SATURDAY, DECEMBER 18, 1999 AT APPROX. 8:18 AM LOCAL TIME, AN EXPERIMENTAL VELOCITY 173 ELITE A/C BUILT AND FLOWN BY^PRIVACY DATA OMITTED^ EXPERIENCED AN ENGINE FAILURE WHILE ON APPROACH TO RUNWAY 36 AT THE MURFREESBORO, TENNESSEE AIRPORT. THE A/C, N627KB, CRASHED NEAR A RESIDENCE AT 1602 LEAF AVENUE, MURFREESBORO, TENNESSEE, 37130.^PRIVACY DATA OM^THE ONLY OCCUPANT, SUFFERED FATAL INJURIES, AND THE A/C SUSTAINED SUBSTANTIAL DAMAGE IN THE ACCIDENT. (.4)THE PILOT WAS ON APPROACH FOR LANDING WHEN THE AIRPLANE EXP ERIENCED A TOTAL LOSS OF ENGINE POWER, AND CRASHED DURING A FORCED LANDING. EXAMINATION OF THE AIRFRAME AND ENGINE ASSEMBLY REVEALED NO EVIDENCE OF A PRECRASH MECHANICAL FAILURE OR MALFUNCTION. VISUAL INSPECTION OF THE SPARK PLUGS REVEALED VERY BLACK AND SOOTY. FUEL WAS PRESENT IN THE FLOW DIVIDER BUT WAS NOT PRESENT IN THE LINE BETWEEN THE FUEL SERVO AND FLOW DIVIDER. THE SERVO FUEL INJECTOR WAS REMOVED AND EXAMINED. THE FUEL DIAPHRAGM HAD NOT BEEN REPLACED. THE SERVO FUEL INJECTOR WAS PLACED IN A TEST BENCH AND A FUNCTIONAL TEST PERFORMED. FUEL WAS POURING OUT OF THE VENTURI CAUSING ERRATIC AIR FLOW THROUGH THE REGULATOR AND ERRATIC AIR FLOW. THE AIR COVER AND DIAPHRAGM WAS REMOVED TO DETERMINE THE SOURCE OF THE FUEL LEAK. THE FUEL DIAPHRAGM STEM WAS BENT. THE CENTER BODY WAS REMOVED WITH THE FUEL DIAPHRAGM ATTACHED TO THE CENTER BODY BELLOWS. THE BOTTOM CALIBRATION NUT WAS REMOVED FROM THE FUEL DIAPHRAGM STEM. THE FUEL DIAPHRAGM WAS REMOVED FROM THE BELLOWS AND A LEAKAGE CHECK WAS PERFORMED. THE BELLOWS WAS SPLIT AND AIR WAS LEAKING THROUGH THE BELLOWS. APPROPRIATE AD'S AND SB'S HAD NOT BEEN COMPLIED WITH RESULTING IN AN IN-FLIGHT POWER LOSS DUE TO AN OVER RICH CONDITION.
