NTSB Identification: FTW99LA064. The docket is stored in the (offline) NTSB Imaging System.

Accident occurred Thursday, December 31, 1998 at BOWIE, TX

Aircraft: Cessna 152, registration: N46285

Injuries: 2 Uninjured



Event: 20001211X11570 Status: Final Report Approved On Friday, April 06, 2001



NTSB Preliminary Narrative (6120.19A)



On December 31, 1998, at 1730 central standard time, a Cessna 152 airplane, N46285, was substantially damaged during a forced landing

following a loss of engine power during initial takeoff climb near Bowie, Texas. The flight instructor and the private pilot receiving instruction

were not injured. The airplane was owned and operated by Aer Mistral, Inc., of Fort Worth, Texas. Visual meteorological conditions prevailed

for the Title 14 CFR Part 91 instructional flight for which a flight plan was not filed. The flight originated from the Meacham International Airport,

near Fort Worth, Texas, one hour and 42 minutes prior to the accident.



In the enclosed NTSB Form 6120.1/2, the operator reported that the fuel tanks were topped off with 16.9 gallons of 100LL aviation fuel prior to

being dispatched to the local training area for an instrument training flight. The flight instructor reported that prior to the accident, he and his

student had been executing practice instrument NDB approaches to the Bowie Municipal Airport under their own navigation, while in VFR

conditions. The approaches were terminated with touch and go landings.



The operator reported that the engine lost power during takeoff from runway 35. He added that the pilot "pitched nose down to avoid a stall."

Subsequently, the airplane landed on rough and uneven terrain, nosed over, and came to rest in the inverted position approximately 10 to 15 feet

from the west edge of the runway.



The flight instructor reported that during initial takeoff climb, he and his student "heard a different engine sound and saw the RPM drop." The

flight instructor added that he assumed the controls of the airplane and "put the nose down." As soon as the flight instructor lowered the nose

of the airplane, the engine sounded normal again; however, he was too low to recover and the nose landing gear impacted the ground.



The airport manager stated that the pilot never reported his position or intentions on the operational Unicom frequency. An eyewitness at the

airport reported that the airplane landed hard in "rough and uneven terrain approximately 300 feet to the west of runway 35 abeam the

numbers." The witness added that the airplane "did not roll much more than 50 feet before it flipped over on its back. "



The 1,800 hour flight instructor and the operator failed to report the mishap to the NTSB or any other agency. The operator recovered the

wreckage of the airplane to his maintenance facility in Fort Worth the day after the accident. The flight instructor stated that after his initial

examination of the airplane at the accident site, he evaluated the damage incurred to the airplane as "minor."



An FAA inspector examined the wreckage at the operator's maintenance facility. His examination confirmed that both wings and the fuselage

sustained structural damage. Cylinder compression was checked, and engine continuity was established to the valve train and the accessory

case. Electrical continuity to both magnetos was established. Evidence of fuel was found in the carburetor, gascolator, fuel lines, and fuel

cells. No pre-existing engine deficiencies were noted and the investigation was not able to determine the reason for the reported loss of engine

power.



The airport manager reported that the winds at the time of the accident were from the north at 5 to 7 knots.



NTSB Final Narrative (6120.4)



The engine lost power during the takeoff portion of a touch and go landing during an instrument training flight. The airplane landed hard in rough

and uneven terrain, nosed over, and came to rest in the inverted position. The flight instructor reported that prior to the accident, he and his

student had been executing practice instrument approaches under their own navigation, while in VFR conditions. The 1,800-hour flight

instructor reported that during the initial takeoff climb, they heard a different engine sound and noticed a drop in engine RPM. The flight instructor

assumed the controls of the airplane and lowered the nose. The engine ran normally after he lowered the nose; however, he was too low to

recover. The reason for the reported loss of engine power could not be determined.



NTSB Probable Cause Narrative



The hard landing due to the flight instructor's delayed remedial action to take control of the airplane when the engine lost power. Factors were

the loss of engine power for an undetermined reason, and the rough and uneven terrain.
