Analysis 

The private pilot reported that he performed several touch-and-go landings at a nearby airport and then returned to his home airport to perform several more touch-and-go landings. As he approached the runway for the third landing, he added throttle to adjust his glidepath; however, the engine did not respond. The pilot added that the engine continued to run but did not produce enough power to maintain altitude. The airplane continued to descend, and its landing gear caught a power line. The airplane then impacted terrain. Fuel was present on site. Examination of the airframe and engine revealed no evidence of preimpact mechanical malfunctions or failures that would have precluded normal operation. The examination noted that the propeller blade tips were bent forward with gouges and chordwise scoring on the leading edges, consistent with the engine producing high power. The pilot reported that he did not apply carburetor heat on the approach; however, weather conditions in the area were conducive to the formation of serious carburetor icing at cruise power settings. Although the pilot did not apply carburetor heat and reported that the engine did not produce enough power to maintain altitude, the postaccident examination did not reveal any airplane mechanical malfunctions or failures, and propeller signatures indicate the engine was producing high power during the accident sequence. Thus, the reason for the pilot’s descent below glidepath could not be determined based on the available information. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s descent below glidepath, which resulted in the airplane’s impact with power lines.

Findings

Aircraft
Descent/approach/glide path - Not attained/maintained (Cause)

Personnel issues
Use of equip/info - Pilot (Cause)

Environmental issues
Wire - Contributed to outcome
Conducive to carburetor icing - Not specified

Factual Information 

On December 27, 2016, about 1830 central standard time, a Piper PA22-108 airplane, N5499Z, impacted a power line and terrain near Piedmont, Missouri. The private rated pilot was not injured and the airplane was substantially damaged during the accident. The airplane was registered to and operated by a private individual under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed at the time.

The pilot reported that he had performed several touch-and-go landings at another airfield, and then returned to the Piedmont Municipal Airport ( KPYN), for additional touch-and-go's. As he approached the runway for the third landing, he added throttle to adjust his glide path; however, the engine did not respond. He added that the engine continued to run, but did not have enough power to maintain altitude. The airplane continued to descend and then the airplane's landing gear caught a power line. The airplane impacted terrain, coming to rest inverted about a half mile short of the runway.

The Federal Aviation Administration (FAA) inspector found that substantial damage was noted to the airplane's fuselage and wings. Fuel was present on site. Further examination of the airplane revealed that control continuity was confirmed to the respective flight and engine controls. When rotated by hand, engine continuity and compression was established on each cylinder. Inspection of the propeller blade tips found they were bent forward; leading edges were gouged and displayed cord wise scoring. No pre-impact abnormalities were noted during the airframe or engine examination.

The automated weather observation facility located at the Poplar Bluff Municipal Airport (KPOF) located 29 miles southeast of the accident site recorded at 1753, wind from 170 degrees at 3 knots, 10 miles visibility, a clear sky, temperature 40 degrees Fahrenheit (F), dew point 34 F, and a barometric pressure of 30.25 inches of mercury.

The carburetor icing probability chart included in Federal Aviation Administration Special Airworthiness Information Bulletin No. CE-09-35, Carburetor Icing Prevention, indicated that the airplane was operating in an area that was associated with a serious risk of carburetor ice formation at cruise power settings.

The pilot stated that he did not use carburetor heat on the approach; adding that the POH (pilot's operating handbook) doesn't call for the use of carburetor heat when at reduced power settings, only at reduced power settings when carburetor icing conditions are present.

PIEDMONT, MO (KFVS) - Piedmont Police Chief Richard Sanders is reporting that a small aircraft has crashed near Piedmont, Missouri on Tuesday, Dec. 27.

According to the Federal Aviation Administration, the aircraft crashed around 6:40 p.m. near the airport after clipping a power line. After crashing, the plane slid into a creek.

Sanders said the plane may have lost power, causing the plane to go down.

The pilot is okay and no other injuries have been reported.

"It's a blessing," he said. 

There are power outages reported around Clearwater Lake. Sanders said the power may be out for a couple hours.

The Federal Aviation Administration will continue to investigate.

Another one bites the dust. Soon all these 1940-1950's planes will be gone.
