Piper PA-18-150, N8048D: Accident occurred July 15, 2012 in North Myrtle Beach, South Carolina

NTSB Identification: ERA12LA453
14 CFR Part 91: General Aviation
Accident occurred Sunday, July 15, 2012 in North Myrtle Beach, SC
Probable Cause Approval Date: 10/04/2012
Aircraft: PIPER PA-18-150, registration: N8048D
Injuries: 1 Uninjured.

NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot stated that he was conducting a banner-tow flight; he turned on final approach at 300 feet above ground level (agl) and reduced the power to the idle position. His airspeed was between 60 and 70 mph. The carburetor heat was not activated, which the pilot indicated was company policy. The company refuted the pilot’s statement regarding carburetor heat. The airplane descended to about 10 feet agl and was 50 feet from the banner pick up poles. He added full power and noticed that the rpm was at 2,500, which was 100 rpm less than full power. He pitched the nose up and the airplane climbed to about 200 feet. The rpm continued to decrease to 1500 rpm. The pilot lowered the nose and checked the throttle, and it was full forward. He increased the mixture, and there was no change in rpm. The airplane would not maintain altitude, and he informed the tower that he was going down. He reduced the throttle to the idle position and lowered the flaps to the full down position. He made a forced landing beyond the banner tow grass area, clearing a berm and colliding with the airport perimeter fence. The airplane nosed over and came to a complete stop and the engine stopped running. The pilot turned the fuel off at the fuel selector valve. The pilot stated that he did not experience any mechanical problems with the airframe or flight controls before the accident. A carburetor icing chart indicated that the airplane was at risk of serious icing at glide power given the weather conditions at the time of the accident.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's inadequate use of carburetor heat during cruise flight, which resulted in a partial loss of engine power and subsequent forced landing.

On July 15, 2012, at 0900 eastern daylight time, a Piper PA-18-150, N8048D, registered to Barnstormers Flite Signs Inc., operating as Title 14 Code of Federal Regulations Part 91 banner tow flight experienced a partial loss of engine power while attempting to pick up a banner. The airplane collided with an airport perimeter fence and sustained substantial damage. The commercial pilot reported no injuries. Visual meteorological conditions prevailed and no flight plan was filed. The flight originated from Grand Strand Airport (CRE), North Myrtle Beach, South Carolina at 0845.

The pilot stated he turned on final approach at 300 feet above ground level (agl) and reduced the power to the idle position. His airspeed was between 60 to 70 mph. The carburetor heat was not activated, which is company policy. When the airplane reached about 10 feet (agl) and 50 feet from the banner pick up poles, he added full power and noticed the rpm was at 2,500 which was 100 rpm less than full power. The pilot pitched the nose up and climbed to 200 feet and the rpm continued to decrease to 1500 rpm. He lowered the nose and checked the throttle and it was full forward. He increased the mixture and there was no change. The airplane would not maintain altitude and he informed the tower that he was going down. He reduced the throttle to the idle position and lowered the flaps to the full down position. He made a forced landing beyond the banner tow grass area, clearing a berm and colliding with the airport perimeter fence. The airplane nosed over and came to a complete stop and the engine stopped running. The pilot turned the fuel off at the fuel selector. The pilot stated he did not experience any mechanical problems with the airframe or flight controls before the accident.

The registered owner stated "It has never been the company policy of Barnstormers Flite Signs to advise a pilot "NOT" use the carb heat in the event of any emergency situation for obvious reasons."

The temperature at the time of the accident was 73 degrees Fahrenheit and the dew point temperature was 72 degrees Fahrenheit. According the carburetor icing chart the airplane would encounter serious icing at glide power.

Review of Advisory Circular 91-51A EFFECT OF ICING ON AIRCRAFT CONTROL AND AIRPLANE DEICE AND ANTI-ICE SYSTEMS states in paragraph 5 DISCUSSION b. " There are two kinds of icing that are significant to aviation: structural icing and induction icing....c. Small aircraft engines commonly employ a carburetor fuel system or a pressure fuel injection system to supply fuel for combustion. Both types of induction systems hold the potential for icing which can cause engine failure. (1) The pilot should be aware that carburetor icing can occur at temperature between 13 degrees Celsius (C) (20 degrees Fahrenheit (F) and +21C (70F) when there is visible moisture or high humidity. This can occur in the carburetor because vaporization of fuel, combined with the expansion of air as it flows through the carburetor, causes sudden cooling, sometimes by a significant amount within a fraction of a second. Carburetor ice can be detected by a drop in rpm in fixed pitch propeller airplanes and a drop in manifold pressure in constant speed propeller airplanes. In both types, usually there will be a roughness in engine operation. Some engines are equipped with carburetor heat for use in both prevention and removal of ice."

NORTH MYRTLE BEACH, SC (WMBF) - The banner plane that crashed into the ocean in North Myrtle Beach was removed from the ocean floor Sunday afternoon. 

 It crashed last Wednesday. A boat pulled the banner plane from 44th Avenue South in North Myrtle Beach to Cherry Grove. The plane's expected to be pulled from the water near the Intracoastal Waterway.

People at the beach had mixed reaction Sunday to there being a plane so close to where they swim.

"I think it's crazy. It's not something you see everyday, that's for sure," Kristen Swisher said.

People lined the beach to watch as dive teams and the owner of the plane spent hours trying to figure out just how they were going to get that plane off the ocean floor.

North Myrtle Beach Patrol Lifeguard Coordinator Monty Reed said the plane owner ended up attaching air bags to the plane, attached it to a boat and drove relatively slow all afternoon. They ended the trip in Cherry Grove where the boat is expected to be removed from the water completely.

Quentin McIlvaine said he is worried about what's going to happen as a result of a plane crashing into the water where he swims.

"The oil. The oil spilling up on the water and getting on people or getting on the fish. And then like just like the safety if someone was swimming and they get cut by glass because the plane crashed and it got broken down," McIlvaine said.

Officer Reed said Beach Patrol is keeping a close eye on the area where the plane sat, to ensure there are no safety issues. Reed said there is no reason for concern.

"It's marked. It's several hundred yards out. Lifeguards won't let them swim that far out so I don't think it's gonna be an issue. Only issue there could be is maybe possibly a fuel spill or anything like that but right now we don't have any reports or anything," Reed said.

Nobody was hurt in that banner plane crash last Wednesday. The pilot of the plane was the only person inside when it crashed, and he made it out safely with the help of some people in the water.
