Accident occurred Monday, October 26, 2015 in Key Biscayne, FL
Probable Cause Approval Date: 08/01/2016
Aircraft: CESSNA 150M, registration: N171RD
Injuries: 2 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 commercial pilot was conducting a personal flight. The pilot reported that, several minutes after takeoff and while en route to his destination airport, the engine began to run roughly and lose power. He subsequently attempted to restore power without success. He then maneuvered the airplane for a forced landing on the fairway of a golf course. The airplane touched down on wet grass, and the pilot was unable to stop the airplane before it collided with two palm trees, which separated the outboard sections of both wings. 

Postaccident examination of the engine revealed that the intake valve of the No. 1 cylinder had failed due to fatigue, which would have resulted in the partial loss of engine power and engine roughness reported by the pilot. The origin and the extent of the fatigue region could not be determined due to postfracture damage. Further examination of the tip of the valve revealed an abnormal contact wear pattern likely caused by either misalignment relative to the valve seat, valve guide wear, or sticking between the valve stem and the valve guide. A review of maintenance records revealed that new cylinders had been installed when the engine was overhauled about 904 total flight hours before the accident.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The fatigue failure of the No. 1 cylinder intake valve, which resulted in the partial loss of engine power.

On October 26, 2015, at 1423 eastern daylight time, a Cessna150M, N171RD, collided with trees during the landing roll following a forced landing on a golf course near Key Biscayne, Florida. The commercial pilot and one passenger were not injured. The airplane was substantially damaged. The airplane was registered to and operated by Ameri Air Support, Inc., under the provisions of 14 Code of Federal Regulations (CFR) as a Part 91 personal flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The flight originated about 22 minutes earlier from the Opa-Locka Executive Airport (OPF), Miami, Florida, and was destined for the Miami Executive Airport, Miami, Florida.

The pilot stated that in preparation of the flight he performed an engine run-up and all parameters were satisfactory. After takeoff the flight climbed to 1,300 feet and proceeded in a southeasterly direction, then south along the coast. After passing the Virginia Key VORTAC, he proceeded in a southerly direction on the 200 degree radial and about 3 miles later, the pilot further reported the engine began to run rough and lose power. Attempts to restore engine power were unsuccessful. He turned back towards Key Biscayne and began looking for a suitable landing spot, indicating his best choice was a golf course. He landed on the fairway of the 18th hole at the Crandon Golf at Key Biscayne.

According to the FAA inspector-in-charge (FAA-IIC), after touchdown on the wet grass, the airplane collided with 2 coconut palm trees resulting in partial separation of both wings outboard of the fuel tanks; the airplane came to rest beyond the palm trees or about 912 feet from the touchdown point. The airplane was recovered for further examination.

Examination of the Continental O-200-A engine, S/N 213516-71A by a FAA airworthiness inspector revealed no suction or compression was noted in the No. 1 cylinder during inspection for crankshaft, camshaft, and valve train continuity. The spark plugs for the No. 1 cylinder were removed and mechanical damage to both was noted. Following removal of the No. 1 cylinder, a hole was noted in the top of the piston with an object embedded into the top of the piston; the head of one valve was not in position. The cylinder and piston were sent for analysis to the NTSB Materials Laboratory located in Washington, D.C.

According to the NTSB Materials Laboratory Factual Report, the intake valve for the cylinder was fractured in the stem just above the head. While most of the fracture was obliterated by post-fracture impact damage, the middle of the fracture exhibited curving crack arrest lines features consistent with fatigue. The fatigue features extended across the entire remaining middle portion of the fracture surface, but the origin or the extent of the fatigue region could not be determined due to post-fracture damage. Inspection of the intake and exhaust valve tips showing the rocker arm contact wear patterns revealed the intake valve had an abnormal wear pattern consisting of a mix of linear wear contact lines rotating about the center mixed with a linear scratch pattern and a diffuse reflective wear patch.


Review of the airplane maintenance records revealed new cylinders were installed when the engine was last overhauled on August 8, 1996. Following overhaul, the engine was installed in the airplane on August 21, 1996; the airplane total time at that time was recorded to be 8,411.0 hours. Maintenance record entries were noted from the engine installation date, to December 15, 2004; the next single entry was dated December 11, 2014. The recorded tachometer time between the 2004 and 2014 entries reflect an increase of 7 hours, though no maintenance record entries were noted. There was no record that the No. 1 cylinder was removed, replaced, or repaired since being installed at engine overhaul in 1996. At the time of the accident, the airframe total time was 9,314.9 hours, and the engine time since major overhaul was about 904 hours.

A total of about 17 gallons of fuel were drained from both fuel tanks. The airplane was recovered for further examination.

KEY BISCAYNE, Fla. (WSVN) -- A pilot carrying one passenger was forced to make an emergency landing on a South Florida golf course, Monday afternoon.

After the pilot reported engine trouble, the Cessna 150 landed on the 18th hole at the Crandon Golf Course at 6700 Crandon Blvd., just before 2:25 p.m. The plane's wing was torn off, and the landing wheels collapsed after the landing. 

Investigators began to take the aircraft apart Monday evening to investigate what could have caused the unexpected landing. 

The aircraft was headed to Miami Executive Airport from Miami-Opa Locka Executive Airport.

The FAA is now investigating what happened. According to the radio transmission to air traffic control, the pilot said that the plane would either land in the water or in the golf course. Fortunately, no one was on the golf course at the time. "Oh, I didn't hear it coming at all," said one witness. "I just heard it when it crashed."

Eye-witness Nancy Superville was the first to see the plane's tricky landing from several feet away. "I was in this van loading up stuff when I heard a bang that felt like it was right behind me, and so I turn around," she said. "When I turn around, I see two persons over there running, so I stuck my head up 'cause you can see over the wall, and I saw the airplane there."

Despite the untimely landing, the two men who were aboard were practically unscathed. "I thought there was dead people 'cause of the sound that it made," Superville said. "I thought they're dead."

Miami-Dade Fire Rescue crews returned to the scene after concerns arose about fuel leaking onto the golf course and worked to contain it. They are asking for spectators to stay away from the area as a precaution. 

Both pilot and passenger spoke with officials on the scene. FAA investigators continue to look into what caused the emergency landing and are expected to speak with the pilot and passenger soon about their findings.
