# NTSB MIA00LA127: Cessna 152, N46912, Murfreesboro, TN, April 4, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: April 4, 2000, 10:35 local (15:35 UTC) - Place: Murfreesboro, TN - Coordinates: 35.780654, -86.330032 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=35.7807&lon=-86.3300&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report March 2, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 48885 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA00LA127 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/48885/pdf - Page: https://openairdocs.org/ntsb/MIA00LA127 ## Probable cause 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. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, takeoff - initial climb - reason for occurrence undetermined (cause) - In flight collision with object, emergency landing after takeoff - terrain condition - none suitable - object - tree(s) - object - wire,transmission ## Analysis 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. ## Factual narrative 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. ## Aircraft - Registration: [N46912](https://openairdocs.org/deregistered/N46912-2000-08-25), registration cancelled 2000-08-25, S/N 15283142, built 1979 (OpenAirDocs) - Reported make and model: Cessna 152 - Registry model: [Cessna 152](https://openairdocs.org/model/cessna-152) (registry code 2071835) (OpenAirDocs) - Registry engine: [Lycoming 0-235 series](https://openairdocs.org/engine/lycoming-0-235-series) (registry code 41505, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 15283142 - Airframe hours: 6720 - Engines: Lycoming O-235-L2C 110 horsepower reciprocating - Damage: Destroyed - Fire: On-Ground - Flight: Instructional, Part 91 - Registered owner: Christina M.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
