Analysis 

***This report was modified on January 3, 2018. Please see the docket for this accident to view the original report.***

The pilot reported that, during a go-around after a low approach, the left cabin door opened. He added that he reached back to close the door and that the airplane then aerodynamically stalled. The pilot was unable to recover, and the airplane impacted the ground and struck multiple fences.

The airplane sustained substantial damage to the fuselage.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's exceedance of the airplane's critical angle of attack during a go-around. Contributing to the accident was the pilot's decision to attempt to close a passenger door during a critical phase of flight.

Findings

Aircraft
Angle of attack - Capability exceeded (Cause)
Passenger/crew doors - Related operating info (Factor)

Personnel issues
Aircraft control - Pilot (Cause)
Decision making/judgment - Pilot (Factor)

Environmental issues
Fence/fence post - Contributed to outcome

Preventing Similar Accidents  

Prevent Aerodynamic Stalls at Low Altitude

While maneuvering an airplane at low altitude in visual meteorological conditions, many pilots fail to avoid conditions that lead to an aerodynamic stall, recognize the warning signs of a stall onset, and apply appropriate recovery techniques. Many stall accidents result when a pilot is momentarily distracted from the primary task of flying, such as while maneuvering in the airport traffic pattern, during an emergency, or when fixating on ground objects.

An aerodynamic stall can happen at any airspeed, at any altitude, and with any engine power setting. Pilots need to be honest with themselves about their knowledge of stalls and preparedness to recognize and handle a stall situation. Training can help pilots fully understand the stall phenomenon, including angle-of-attack (AOA) concepts and how weight, center of gravity, turbulence, maneuvering loads, and other factors can affect an airplane's stall characteristics. The stall characteristics may be different in each type of airplane, so learn them before you fly.

The stall airspeeds marked on the airspeed indicator (for example, the bottom of the green arc and the bottom of the white arc) typically represent steady flight speeds at 1G at the airplane's maximum gross weight in the specified configuration. Maneuvering loads and other factors can increase the airspeed at which the airplane will stall. For example, increasing bank angle can increase stall speed exponentially.

Reducing AOA by lowering the airplane's nose at the first indication of a stall is the most important immediate response for stall avoidance and stall recovery. This may seem counterintuitive at low altitudes, but is a necessary first step.

AXTELL, Kan. (KWCH) - No one was hurt after a plane crash on Friday afternoon near Axtell.

According to the Kansas Highway Patrol, 18-year-old Nicholas Buessing was piloting the plane one mile west of Axtell when the door opened unexpectedly. Buessing tried to grab the door but ended up flying the plane into the ground.

The crash happened one mile west of Axtell on Jayhawk Road.

One other passenger was inside of the plane at the time.

MARSHALL COUNTY – Two people avoided serious injury after an airplane accident just before 2p.m. Friday in Marshall County.

A 1948 Cessna 170 fixed wing aircraft piloted by Nicholas Buessing, 18, Axtel, was 600 feet above the ground with a ground speed of 90 mph in the 2900 Block of Jayhawk Road, one mile West of Axtell, according to the Kansas Highway Patrol.

The pilot’s side door opened unexpectedly. When the pilot reached to grab the door, he lost control of the aircraft and it struck the ground.

Buessing and a passenger Christian Buessing, 21, Axtel, were not injured.

The Federal Aviation Administration is investigating the incident, according to the KHP.
