Location: Troy, MO
Accident Number: CEN18LA095
Date & Time: 02/08/2018, 1152 CST
Registration: N600HH
Aircraft: HENDERSON THORP T 18
Aircraft Damage: Substantial
Defining Event: Controlled flight into terr/obj (CFIT)
Injuries: 1 Serious
Flight Conducted Under: Part 91: General Aviation - Personal 

Analysis 

During a personal flight, the private pilot reported that he made one pass over the runway, which was oriented east to west, and noted a crosswind from the southwest. During final approach, the pilot extended the flaps "one notch" to add "a little speed" to compensate for the crosswind. The pilot then looked down at the instrument panel to check the rate of descent; when he looked back outside, he saw a small tree limb near the airplane's right wing tip. The pilot made a left control input, but the right wing tip impacted the tree, and the airplane turned slightly to the right. The airplane impacted several other trees and then nosed down into the ground. The pilot reported no airplane mechanical malfunctions or failures.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain adequate clearance from trees while landing in crosswind conditions.

Findings

Aircraft
Crosswind correction - Not attained/maintained (Cause)

Personnel issues
Incorrect action performance - Pilot (Cause)

Factual Information 

On February 8, 2018, at 1152 central standard time, an amateur-built T-18 airplane, N600HH, collided with trees and terrain during landing at Woodland Airstrip (MU89), Troy, Missouri. The private pilot, who was the sole occupant, sustained serious injuries and the airplane sustained substantial damage. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed at the time of the accident and no flight plan had been filed. The flight departed Creve Coeur Airport (1H0), St. Louis, Missouri, about 1030.

The plot reported that upon arrival at MU89 he made one pass over runway 27 and noted a crosswind from 230° at 10 to 20 knots. The pilot continued into the traffic pattern for a full stop landing on runway 27. During final approach while aligned to the left side of the runway and about 90 mph, the pilot extended the flaps "one notch." The pilot added that he wanted a little speed due to the crosswind on final. The pilot looked down at the instrument panel to check the rate of descent and when he looked back outside he saw a small tree tip near the airplane's right wing tip. He initiated a left control input, but the right wing tip collided with the tree and the airplane turned slightly right. The airplane continued into several trees and then nosed down into the ground. The pilot reported that there were no airplane mechanical malfunctions or failures.

The responding Federal Aviation Administration (FAA) inspector performed a postaccident examination of the airplane and accident site. There was evidence of broken tree limbs about 30 to 40 yards east of the main wreckage. The airplane came to rest next to a tree line in a nose low, vertical attitude (figure 1). Flight control continuity was confirmed and no preimpact anomalies were evident.

LINCOLN COUNTY, Mo. — A single-engine plane crashed into some trees near Wolf Creek Road and State Highway U Thursday afternoon in Lincoln County.

The Lincoln County Sheriff's Department reports that the pilot suffered a broken arm and was taken to the hospital.

There is no word yet on what caused the crash.

A pilot was hospitalized after his small plane crashed Thursday afternoon in Lincoln County.

The pilot was the only person on board when the single-engine plane came down and skimmed some trees before crashing.

The plane crashed nose down on a gravel road parallel to a private landing strip. It happened just before noon in an unincorporated area of Lincoln County near Wright City. Several fire departments and the Missouri State Highway Patrol responded to the scene.

By the time they got there, a neighbor was helping get the pilot out of the plane. The neighbor, who did not want to be identified, said he heard two loud noises and saw the pilot's wife running to the crash.

"He was still in the plane he was standing up out on his our the front of it where the front windscreen would be and he says, 'I need to get out of here, but I can't because my hand hurts.' So I went over there and he put his arm around my shoulders and we lifted him up," the man said.

The pilot was hospitalized with non-life threatening injuries. His name has not been released.

"He has a fractured arm and a head injury of some sort. As far as the rest of the extent of his injuries, I don't know," said Wright City Fire Protection District Chief Ron MacKnight.

The FAA was on the scene trying to determine the cause of the crash.

LINCOLN CO. (KMOV.com) – A pilot suffered a broken arm after a small plane crashed in Lincoln County Thursday.

Missouri State Highway Patrol officials said pilot Mike Fleming was the only person on the plane when it crashed at Wolf Creek Road and Highway U around noon. According to authorities, the narrow private road doubles as a private airstrip.

"I was in the house making lunch and I heard what sounded like an empty dump truck coming down a gravel road," said Fleming's neighbor, who wanted to remain anonymous.

The crash happened just a few feet from the man's home. 

"I wouldn't be able to live with myself if I just stood over here," he said. "So I went over there and he put his arm around my shoulders and we lifted him up and got him out over it."

Following the crash, Fleming was taken to the local hospital for treatment. Despite the heavy damage done to the aircraft itself, Fleming suffered only a broken hand and arm. 

"Could definitely have been a lot worse. when we got over there fuel was pouring out and it could've caught on fire," said Ron MacKnight, Fire Chief for Wright City. "We always prepare for the worst and hope for the best and this is one of those best case scenarios."
