NTSB Identification: FTW99LA066. The docket is stored in the (offline) NTSB Imaging System. |
Accident occurred Sunday, January 10, 1999 at CONWAY, AR |
Aircraft: Cessna 150H, registration: N23303 |
Injuries: 2 Uninjured |
Event: 20001204X00057 Status: Final Report Approved On Wednesday, April 18, 2001 |
NTSB Preliminary Narrative (6120.19A) |
On January 10, 1999, at 1310 central standard time, a Cessna 150H airplane, N23303, was substantially damaged during a forced landing |
following the loss of engine power while on final approach near Conway, Arkansas. The non-instrument rated private pilot and her passenger |
were not injured. The airplane was registered to and operated by the Bobwhite Hill Ranch, Inc., also of Conway, Arkansas. Visual |
meteorological conditions prevailed for the Title 14 CFR Part 91 local flight for which a flight plan was not filed. The personal flight originated from |
the pilot's private grass airstrip approximately 5 minutes prior to the accident. |
The pilot reported that, as part of a local orientation flight for her passenger, she intended to land at the Dennis F. Cantrell Field Airport near |
Conway, Arkansas. After entering the traffic pattern on a modified right base, the pilot stated that she configured the airplane with 10 degrees |
of flaps as she established the airplane on a long final approach for runway 25. She reported that she reduced the engine power to between |
1,500 and 1,600 RPM, and applied carburetor heat. The pilot added that while the airplane was descending through 1,600 feet msl, she noted |
that the rate of descent was higher than she anticipated, so she added power to arrest the rate of descent. The pilot further stated that the |
engine failed to respond to her power application; however, the propeller continued wind milling. |
The 606-hour pilot told the FAA inspector who responded to the accident site that the airplane was over a residential area and after failing to |
reestablish engine power, she elected to "stall-out the airplane over the trees to avoid impacting the houses." |
The pilot further stated that the right wing of the airplane collided with a utility wire resulting in the airplane's change of direction. The main |
landing gear impacted a ditch on the shoulder of the highway. The airplane came to rest on an easterly direction between a busy highway and a |
residence. |
Examination of the wreckage by the FAA inspector revealed that the aft portion of the empennage was bucked aft of the baggage compartment, |
and the horizontal and vertical stabilizers, as well as the left wing sustained structural damage. The inspector added that fuel was found in both |
fuel cells. |
The temperature at the time of the accident was reported at 48.2 degrees, with the dew point at 42.8 degrees Fahrenheit. According to the |
enclosed carburetor icing probability chart, the prevailing temperature and dew point combination places the aircraft in the probability range for |
serious carburetor icing. |
NTSB Final Narrative (6120.4) |
The private pilot reported that the engine lost power without warning while descending on final approach. The airplane was configured with 10 |
degrees of flaps as she established the airplane on a long final approach for the runway. She added that while the airplane was descending |
through 1,600 feet msl, she noted that the rate of descent was higher than she anticipated, so she added power to arrest the rate of descent. |
The pilot further stated that the engine failed to respond to her power application. The 606-hour pilot told the FAA inspector that the airplane was |
over a residential area and after failing to reestablish engine power, she elected to 'stall-out the airplane over the trees to avoid impacting the |
houses.' The right wing of the airplane collided with a wire resulting in the airplane's change of direction, and subsequent impact with the |
ground. Fuel was found in both fuel cells. The temperature at the time of the accident was reported at 48.2 degrees, with the dew point at 42.8 |
degrees Fahrenheit. According to the enclosed carburetor icing probability chart, the temperature and dew point combination places the aircraft |
in the probability range for serious carburetor icing. |
