| NTSB Identification: MIA00LA127. The docket is stored in the (offline) NTSB Imaging System. |
| Accident occurred Tuesday, April 04, 2000 at MURFREESBORO, TN |
| Aircraft: Cessna 152, registration: N46912 |
| Injuries: 2 Uninjured |
| Event: 20001212X20876 Status: Final Report Approved On Friday, March 02, 2001 |
| NTSB Preliminary Narrative (6120.19A) |
| On April 4, 2000, about 1035 central daylight time, a Cessna 152, N46912, registered to Middle Tennessee State University, operating as a Title |
| 14 CFR Part 91 instructional flight, crashed on takeoff climb in the vicinity of Murfreesboro, Tennessee. Visual meteorological conditions |
| prevailed and a VFR flight plan was filed but not activated. The airplane was destroyed by postcrash fire, and the CFI-rated pilot and student |
| pilot were not injured. The flight departed one minute before the accident. |
| According to the CFI, the flight had just departed runway 36 at Murfreesboro Municipal Airport. At about 100 feet agl, while in departure climb, |
| the engine began to run rough, continued climb became impossible, and the airplane collided with a tree and power lines less than 1/2 mile north |
| of the airport. The empennage separated and remained entangled in the power lines and the fuselage landed at the base of a stand of trees and |
| burned. |
| According to the student, preflight inspection of the aircraft revealed no discrepancies. Sumping each fuel tank revealed no water and the |
| tanks were full. The engine started smoothly, ran smoothly for the taxi, and pre-takeoff engine checks were normal. |
| The flight school could not provide a record of fuel farm or fuel truck contamination checks, but according to a fuel truck status sheet, N46912 |
| was fuelled with 6.6 gallons of fuel on April 3rd. At some time after that fuelling on April 3rd, the fuel truck status sheet shows the following |
| entries: (1) "filled truck" and (2) "sumped truck". According to the line serviceman on duty, it was the flight school's procedure to, "report any |
| contamination to someone in charge". The flight school confirmed no report was given for that day. |
| According to an FAA inspector, postcrash fire limited examination of the engine and fuel components. Fuel contamination testing was |
| impossible due to the introduction of fire retardant foam to the wreckage by fire rescue personnel; however, correct 100LL aviation fuel was |
| determined to be aboard. The fuel filler caps appeared properly sealed and vented and the remaining vent tube from the left wing was not |
| obstructed. The four fuel tank pick-ups were not obstructed. Subsequent disassembly examination of the engine revealed proper accessory |
| drive and valve train relationship and continuity. All eight spark plugs revealed normal electrode coloring per Champion Spark Plugs Check-A-Plug |
| chart AV-27 and tested satisfactorily. Magneto timing appeared correct, and both magnetos tested satisfactorily. Borescoping and compression |
| testing of the cylinders proved satisfactory. The oil filter revealed no contamination or metal particles. The fire-damaged carburetor was removed |
| and revealed no remnants of debris in the float-bowl or the fuel strainer. The throttle plate was found fully open. |
| NTSB Final Narrative (6120.4) |
| The instructional flight sustained an engine power loss at about 100 feet agl, during takeoff. Unable to climb and with no clear area to force |
| land, the flight collided with a tree and power lines, impacted the terrain, and burned. Fire damage and fire fighting foam sprayed on the crash |
| site prevented a thorough examination of the wreckage for water contamination of the fuel. The engine was subjected to disassembly |
| examination with no conclusive finding. |
| NTSB Probable Cause Narrative |
| A loss of engine power during takeoff climb for undetermined reasons resulting in an attempted emergency landing to unsuitable terrain and |
| collision with a tree and transmission wires. |
