Aircraft involved
Probable cause & findings
The failure of the pilot to use carburetor heat during descent resulting in loss of engine power due to carburetor icing and the airplane colliding with a fence and nosing over during a forced landing.
Factual narrative
On February 6, 2001, about 1430 Atlantic standard time, a Cessna A150K, N5915J, registered to East Wing Aviation, Inc., collided with terrain while maneuvering near Cabo Rojo, Puerto Rico, while on a Title 14 CFR Part 91 personnel flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft received substantial damage and the private-rated pilot and one passenger were not injured. The flight last departed Ponce, Puerto Rico, the same day about 1400. The pilot stated he flew from Humacao, Puerto Rico, to Ponce, where he fueled the airplane, adding 13.8 gallons of fuel. After fueling he drained about 1/2 inch of water from both tanks. They departed Ponce at 1400, en route to take Cabo Rojo, to take photos of his fathers land. His father was the passenger. Arriving over Cabo Rojo at 1,500 feet, he descended to 1,000 feet. After seeing the property they were going to photograph, he cut power to a minimum and started a descent to the planned altitude of 600 feet. He did not use carburetor heat for the descent. When level at 600 feet, the airplane was not maintaining altitude because of the tailwind. He knew the pass was not safe coming downwind and he applied full engine power. With the engine at full power for a reasonable period of time, the airplane did not gain altitude or engine power. The last thing he remembered was being at 100 feet trying to make a safe landing. He later learned that the airplane touched down, collided with a fence, and then nosed over. The pilot stated on the NTSB Pilot/Operator Aircraft Accident Report, that he did not have any mechanical failures with the airplane. The owner of the airplane reported to an FAA inspector about 1 hour after the accident, that the pilot had been flying low over some property and that he had crashed the airplane. Post crash examination of the airplane and engine by an FAA inspector showed that when the carburetor throttle was activated, a stream of 100 low lead fuel was ejected about 18 inches from the carburetor by the accelerator pump. The left magneto sparked when the magneto was rotated by hand. The fuel strainer was clear of debris and contained 1 drop of water. A carburetor icing probability chart showed that at the time of the accident the airplane was operating in conditions conducive to serious carburetor icing at glide power. See carburetor icing probability chart. The pilot stated that he and the passenger planned to take pictures of some property. They arrived over the area at 1,500 feet and then descended to 1,000 feet. When the property was located, he reduced engine power to a minimum and descended to 600 feet. When level at 600 feet, the airplane would not maintain altitude. He applied full engine power and the engine did not obtain power and the airplane continued to descend. The airplane touched down in a clear area and collided with a fence at which time it nosed over. Post crash examination of the airplane and engine by an FAA inspector showed no evidence of precrash failure or malfunction. The pilot stated he did not use carburetor heat for the descent. A carburetor icing probability chart showed the airplane was operating in conditions conducive to serious carburetor icing at glide power.
