CANTON, KS, USA

Aircraft #1

N9151R

Cessna 188B

Analysis

THE PILOT STATED THAT BEFORE TAKEOFF, HE PERFORMED A MAGNETO, PROPELLER, AND ENGINE INSTRUMENT CHECK. HE REPORTED THAT DURING THE TAKEOFF ROLL ON A GRASS AIRSTRIP (2600' X 40'), THE AIRPLANE'S TAIL CAME UP APPROXIMATELY 800 FEET DOWN THE RUNWAY, BUT HE NOTICED THAT THE AIRPLANE WAS UNDERPOWERED. HE EXTENDED FULL FLAPS, AND THE AIRPLANE THEN BECAME AIRBORNE. THE PILOT STATED THAT HE THEN RETRACTED THE FLAPS AND REMAINED IN GROUND EFFECT, WHILE HE VERIFIED THE CONTROL SETTINGS OF THE MIXTURE, PROPELLER, AND THROTTLE. HE CONTINUED TO FLY FOR ABOUT 1000 FEET, BUT HE STATED THAT HE WAS UNABLE TO GAIN EITHER ALTITUDE OR AIRSPEED. WITH TREES AHEAD, THE PILOT DUMPED HIS LOAD OF CHEMICALS AND MANEUVERED TO THE LEFT; HOWEVER, THE AIRPLANE STALLED AND IMPACTED THE GROUND. NO MECHANICAL ANOMALIES WERE FOUND DURING A POSTACCIDENT EXAMINATION.

Factual Information

On August 14, 1995, at 0830 central daylight time, a Cessna 188B, N9151R, operated by Spraybirds Inc. of McPhersen, Kansas, was substantially damaged while attempting to take off from a private grass airstrip in Canton, Kansas. The commercial certificated pilot reported no injuries. The local 14 CFR Part 137 aerial agricultural flight operated without flight plan in visual meteorological conditions. Prior to taking off for the second spraying run for the day, the pilot stated that he performed a magneto, propeller, and engine instrument check. He reported all indications were normal. The pilot stated that during the takeoff roll on the grass airstrip (2600' x 40'), "the tail came up about 800 feet down the runway and I noticed that the airplane was underpowered." The pilot stated that he added full flaps, and the airplane then became airborne. He then retracted the flaps and continued to stay in ground effect while he verified that the mixture, propeller setting, and throttle control were all full forward. "I flew approximately 1000 feet but gained neither altitude or airspeed. With trees a few hundred feet ahead I dumped the load and pulled left. I felt the airplane stall to the left," the pilot stated. The airplane impacted the ground. Postaccident examination revealed no mechanical anomalies.

Probable Cause and Findings

failure of the pilot to obtain the proper flying speed or to abort the takeoff, while there was sufficient runway remaining, which resulted in an inadvertent stall.
