Location: Centerville, TN
Accident Number: GAA17CA504
Date & Time: 08/18/2017, 1540 EDT
Registration: N4859N
Aircraft: BOEING E75
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Instructional
Analysis
The pilot receiving instruction reported that, during the landing roll before stopping, the tailwheel-equipped biplane "made a sudden move to [the] left." He added that the flight instructor's quick reactions kept the biplane on the runway and going straight.
The pilot then regained control of the biplane, and the left wing dropped and "despite corrective inputs on the controls would not respond to further control inputs," and the airplane then ground looped to the right. Subsequently, the left main landing gear collapsed, and the biplane came to rest nose down on the runway.
The biplane sustained substantial damage to all four wings and fuselage.
The pilot reported that "it was [his] personal contention and belief that the upper left gear failed[,] resulting in substantial damage to the [biplane] and the resultant ground loop." He added that "[he] did not believe that this particular incident could have been prevented."
A review of a video of the accident showed, in part, a loss of control early in the landing roll, followed by a subsequent loss of control and ground loop to the right.

Preventing Similar Accidents
Stay Centered: Preventing Loss of Control During Landing
Loss of control during landing is one of the leading causes of general aviation accidents and is often attributed to operational issues. Although most loss of control during landing accidents do not result in serious injuries, they typically require extensive airplane repairs and may involve potential damage to nearby objects such as fences, signs, and lighting.
Often, wind plays a role in these accidents. Landing in a crosswind presents challenges for pilots of all experience levels. Other wind conditions, such as gusting wind, tailwind, variable wind, or wind shifts, can also interfere with pilots’ abilities to land the airplane and maintain directional control.
What can pilots do?
Evaluate your mental and physical fitness before each flight using the Federal Aviation Administration’s (FAA) “I'M SAFE Checklist." Being emotionally and physically ready will help you stay alert and potentially avoid common and preventable loss of control during landing accidents.
Check wind conditions and forecasts often. Take time during every approach briefing to fully understand the wind conditions. Use simple rules of thumb to help (for example, if the wind direction is 30 degrees off the runway heading, the crosswind component will be half of the total wind velocity).
Know your limitations and those of the airplane you are flying. Stay current and practice landings on different runways and during various wind conditions. If possible, practice with a flight instructor on board who can provide useful feedback and techniques for maintaining and improving your landing procedures.
Prepare early to perform a go around if the approach is not stabilized and does not go as planned or if you do not feel comfortable with the landing. Once you are airborne and stable again, you can decide to attempt to land again, reassess your landing runway, or land at an alternate airport. Incorporate go-around procedures into your recurrent training.
During landing, stay aligned with the centerline. Any misalignment reduces the time available to react if an unexpected event such as a wind gust or a tire blowout occurs.
Do not allow the airplane to touch down in a drift or in a crab. For airplanes with tricycle landing gear, do not allow the nosewheel to touch down first.
Maintain positive control of the airplane throughout the landing and be alert for directional control difficulties immediately upon and after touchdown. A loss of directional control can lead to a nose-over or ground loop, which can cause the airplane to tip or lean enough for the wing tip to contact the ground.
Stay mentally focused throughout the landing roll and taxi. During landing, avoid distractions, such as conversations with passengers or setting radio frequencies.

The FAA’s “Airplane Flying Handbook” (FAA-H-8083-3B), chapter 8, “Approaches and Landings,” provides guidance about how to conduct crosswind approaches and landings and discusses maximum safe crosswind velocities. The handbook can be accessed from the FAA’s website (www.faa.gov).
The FAA Safety Team (FAASTeam) provides access to online training courses, seminars, and webinars as part of the FAA’s “WINGS—Pilot Proficiency Program.” This program includes targeted flight training designed to help pilots develop the knowledge and skills needed to achieve flight proficiency and to assess and mitigate the risks associated with the most common causes of accidents, including loss of directional control.

CENTERVILLE, TN (WSMV) - Officials said a small plane crashed at the Centerville Municipal Airport on Friday afternoon.
Airport manager Woody Woodruff said the plane was coming in to land around 3:30 p.m. when conditions got rough and the plane crashed.
The plane didn’t flip, but the wings were torn off.
Two people were in the plane at the time. No one was hurt.
The airport is shut down while they clean up.
Woodruff said the runway should be cleared in a short amount of time.
