Landing Area Overshoot: Cessna 172A, N7243T; accident occurred July 27, 2017 near Enumclaw Airport (WA77), King County, Washington

The left and right muffler remained attached. The tailpipes received impact damage.

The induction system remained intact except the carburetor mounting flange. See Carburetor. The induction filter was contaminated with dirt and grass.

The left magneto exhibited no damage.

The right magneto exhibited no damage

The ignition harness exhibited impact damage at sparkplug connections on cylinders one, three and five.

The sparkplugs appeared to be new and were intact with the exception of the top sparkplug removed from cylinder # 2. When compared to a Champion “Check-APlug” chart, the conditions were normal. All four sparkplugs exhibited a slightly darker than normal color and exhibited an odor consistent with auto fuel.

This fuel primer is located with other engine controls in the lower center of the cabin instrument panel. The primer was found in an unlocked position. See red arrow.

The carburetor was undamaged with the exception of the mounting flange which partially separated. The throttle plate was in the wide-open position as was the cabin control. Throttle and mixture arms and cables remained secured. Control cable continuity was confirmed from the instrument panel to the carburetor. The carburetor exhibited an odor consistent with auto fuel.

The aftermarket spin-on-oil filter and oil filter adapter received impact damage. A red silicone type gasket separated from the oil filter adapter mount.

All cylinders remained attached to its respective base and no impact damage was noted. A lighted electronic borescope inspection was performed. All intake and exhaust valves were examined and found intact. Normal to dark combustion signatures were noted on valve faces and piston domes. Rocker covers were removed to observe rocker arm movement.

All rocker arms and shafts were intact and movement was noted when the engine was partially rotated (manually).

The crankshaft separated at the propeller flange. The break exhibited 45 degree sheer lips and ladder cracks around the diameter of the shaft.

Camshaft continuity was confirmed by rotating (partial rotation only) the engine manually and noting the valve train rocker arms in motion.

Starter: No damage was noted.

The vacuum pump remained intact and attached. The data plate was worn and the model number obscured. The input and output fittings separated.

Location: Enumclaw, WA
Accident Number: WPR17LA169
Date & Time: 07/27/2017, 2030 PDT
Registration: N7243T
Aircraft: CESSNA 172A
Aircraft Damage: Substantial
Defining Event: Landing area overshoot
Injuries: 2 Serious, 1 Minor
Flight Conducted Under: Part 91: General Aviation - Personal

On July 27, 2017, about 2030 Pacific daylight time, a Cessna 172A airplane, N7243T, collided with an airport perimeter fence during takeoff, and subsequently impacted terrain near Enumclaw Airport (WA77), Enumclaw, Washington. The private pilot and the student pilot sustained serious injuries; another passenger sustained minor injuries. The airplane was substantially damaged. The airplane was registered to the student pilot and operated as a Title 14 Code of Federal Regulations Part 91 personal flight. Visual meteorological conditions prevailed, and no flight plan had been filed for the local flight.

In the National Transportation Safety Board (NTSB) Pilot/Operator Aircraft Accident/Incident Report (form 6120.1), the student pilot reported that he had no knowledge of the flight, and that he could not recall any details surrounding the accident. He also reported that the operator of the airplane at the time of the accident was the private pilot. After several attempts, the NTSB investigator-in-charge was unable to establish contact with the private pilot, who did not possess a current Federal Aviation Administration (FAA) airman medical certificate; his most recent medical certificate expired in 1992. The student pilot stated that he was under the impression that the private pilot was current.

A witness located at the airport reported that the airplane was doing touch-and-go landings. During the last landing, the airplane touched down near the departure end of the runway, attempted to stop, skidding the left main tire, and with approximately 40 yards remaining, added power for the takeoff attempt. The airplane travelled off the end of the runway, through the grass before it collided with the airport perimeter fence.

The airplane came to rest in a nose-down position and was oriented in a westerly direction about 400 ft east of the departure end of runway 07. The airplane's landing gear tracks were observed throughout the grass at the end of the runway. The left main landing gear tire left a long skid mark visible on the runway; main and nose landing wheel tracks were visible in the grass until about 20 ft from the fence.

The propeller was separated and located 23 ft southwest of the airplane. One blade was imbedded in the ground, while the other blade was observed relatively undamaged. The nose gear was broken and pushed up and to the right, the engine was pushed back into the firewall, and the aft fuselage was wrinkled and showed compression damage on the right side. The flaps were found extended at 40°. The mixture and throttle controls were set at full rich and maximum power. The Hobbs meter displayed 1,041.7 hours, with a tach time of 772.51 hours. The airplane had two strands of barbed wire wrapped around it, which extended from its nose to tail and back to its nose. The barbed wire passed between the inboard end of the right elevator control surface and the tail cone.

Leaves and tree debris were spread on the path between the runway and the wreckage; the top rail of the fence was located on the path and was bent. The barbed wire chain link fence on the east end of the runway was depressed at the same spacing as the left, right, and nose wheel lateral spacing on the airplane which indicated that the landing gear contacted the top of the fence and took the barbed wire along as the airplane passed over the fence. About 258 ft of the top rail was missing from the fence.

Examination of the recovered airframe and engine did not reveal any evidence of a preexisting mechanical malfunction that would have precluded normal operation. The complete engine and airframe examination reports are appended to this accident in the public docket.

Additional Information

In the conversation with the student pilot's flight instructor, he indicated that, during the instructional flights, him and the student pilot did not practice landings, and that the student pilot had never executed any landings on his own.

On July 27, 2017, about 2030 Pacific daylight time, a Cessna 172A, N7243T, collided with the airport perimeter fence during takeoff and subsequently impacted terrain near the Enumclaw Airport (WA77), Enumclaw, WA. The student pilot and the pilot rated passenger sustained serious injuries; another passenger sustained minor injuries. The airplane was substantially damaged. The airplane was registered to and operated by the owner as a 14 Code of Federal Regulations Part 91 personal flight. Visual meteorological conditions prevailed, and no flight plan had been filed.

A witness located at the airport reported that the pilot was conducting touch and go landings. During the last touch and go, the airplane touched down at the departure end of the runway. The pilot took off to the east and the nose landing gear contacted a barbed wire fence. About 200 feet of the wire separated from the fence; a large part of the fence was twined around the airplane, with some parts located in the nearby trees. Another witness stated the airplane flew from west to east at a treetop level. It executed a slow left turn followed by an immediate right turn back towards the airport. The engine sounded as if it was developing full power. Moments later, the airplane impacted terrain.

On Thursday night, a plane flying in and out of the Enumclaw airport crash landed in the nearby Rainier Trails Park.

The Enumclaw Police Department started receiving calls about the crash around 8:56 p.m.

The plane, a single-engine Cessna 172, was nose down in the grass, just a few feet away from the playground at the park.

When first responders arrived, the pilot was pinned inside the aircraft and was extracted by the Enumclaw Fire Department.

According to EFD Fire Chief Randy Fehr, 32 firefighters and were on the scene, including crews from the Buckley City Fire Department, Mountain View Fire and Rescue, Puget Sound Regional Fire Authority, King County Medic 1 and Maple Valley Life and Safety.

The other two passengers were treated at the scene.

According to a police press release, the pilot and one of the passengers were airlifted to Harborview Medical Center with life threatening injuries.

The third passenger was driven to Harborview with serious injuries.

It’s been reported on Friday, July 29, one man was upgraded to serious condition, and the woman to satisfactory condition.

There were no other injuries, as the playground was empty at the time of the crash.

That Friday morning, investigators from the National Transportation Safety Board and the Federal Aviation Administration were examining the crash.

Cari Enticknap, one of the many people in her neighborhood that heard the crash, said the pilot could have been practicing “touch and go’s” when he crashed.

“There was a lot of take off, land, take off, land, take off, land,” she said. “And then the awkward takeoff and the crash.”

It is not confirmed whether the plane was taking off or landing.

It does appear the pilot hit a barbed wire fence on the side of the road along 244th Avenue SE. This might have at least partially caused the crash, as barbed wire could be seen wrapped around the plane’s wings and tail.

Pieces of the fence could also be seen scattered near the entrance of the neighborhood.

Enticknap said on that last run, the pilot cleared their house by just about 10 or 15 feet before he turned around and crashed at the park.

“Our kids usually play football here in this field,” she said. “Last night thankfully none of them were out here.”

Other witnesses said it was unusual the pilot was taking off east, toward the neighborhood, as the vast majority of planes take off and land facing west.

ENUMCLAW, Wash. - One person remains in critical condition and another person is in serious condition after a small plane crashed into a park in Enumclaw Thursday night, nearly hitting a playground.

A third victim in the crash has been upgraded to satisfactory condition as of Friday morning, according to the nursing supervisor at Harborview Medical Center.

It was around 9 p.m. when the Cessna 172 crashed near the Enumclaw Airport just off of 244th Avenue Southeast.

One witness says he heard a loud thud and ran out of his house and saw the crash. Another says they ran out and tried to help the victims.

"We heard a sound, it wasn't followed by an explosion, but it was definitely a 'thud'-type sound," said Darren Rawie.

Two people were airlifted to Harborview Medical Center in downtown Seattle, a spokesperson with the Enumclaw Fire Department says. The third person was taken to Harborview by ambulance.

There is no word yet what caused the plane to crash.

The FAA and NTSB are investigating. An FAA spokesperson told KOMO News the plane was not currently registered with the FAA, although it may have been in the process of being registered. They will determine for sure during the investigation.
