Accident Number: CEN17LA236
Date & Time: 06/18/2017, 0715 MDT
Registration: N999WX
Aircraft:  WELLS JOHN L JR STOL CH 701
Aircraft Damage: Substantial
Defining Event: Fuel starvation
Injuries: 1 Minor
Flight Conducted Under:  Part 91: General Aviation - Flight Test

Analysis

The commercial pilot reported that, during initial climb after takeoff, the amateur-built airplane's engine experienced a partial loss of power. As he attempted to return to the airport, the engine lost total power. He subsequently conducted a forced landing on rough terrain, during which the right wing and fuselage sustained damage.

Postaccident examination of the engine revealed that the fuel hose from the left wing tank had deteriorated from the inside, which would have restricted the flow of fuel to the engine and led to fuel starvation and the subsequent loss of engine power. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
Fuel starvation due to the deterioration of a fuel hose.

Findings

Aircraft
Fuel distribution - Damaged/degraded (Cause)
Fuel - Fluid level (Cause)

Environmental issues
Rough terrain - Contributed to outcome


Factual Information

On June 18, 2017, about 715 mountain daylight time, an amateur-built Wells STOL CH701 airplane, N999WX, sustained substantial damage to the fuselage and firewall during a forced landing to a field near Canon City, Colorado, after the airplane's engine lost power during initial climb after takeoff from the Fremont County Airport (1V6), Canon City, Colorado. The pilot received minor injuries. 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 for the flight, which was not operated on a flight plan. The flight was originating from 1V6 when the accident occurred.

The pilot reported that the airplane experienced a partial loss of engine power during initial climb about 6,500 feet msl. As he attempted to return to 1V6, the engine suddenly lost complete power. A forced landing was completed to rough terrain. The airplane incurred damage to the right wing and fuselage during the landing attempt. The pilot reported that after the accident he found that the fuel hose from the left fuel tank had deteriorated from the inside causing an obstruction to the normal flow of fuel.

Analysis

The solo student pilot reported that, as the airplane entered ground effect, while landing in crosswind conditions, a gust of wind lifted the airplane and pushed it to the left. He added that he initiated a go-around and "[pushed] the nose down slightly to gain lift". He further added that, during the go-around, he "must have relaxed the aileron countering the wind", and a gust of wind pushed the airplane to the left. Subsequently, the airplane impacted the ground and spun around.

The airplane sustained substantial damage to the engine mount.

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

The automated weather observation system located on the airport reported, about 23 minutes before the accident, the wind was from 180° at 15 knots, gusting to 21 knots. The student pilot landed on runway 16. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The student pilot's failure to maintain crosswind correction during a go-around in gusting wind conditions.

Analysis


The solo student pilot reported that, during landing, the airplane "ballooned up and [he] added a little throttle [to] settle the [airplane]". He added that, "the [airplane] seemed to settle but felt like it was coming down too fast". He applied full power to go around and reduced the flaps to 20°. He added that, "the [airplane] was stalling and so [he] moved the flaps to 0 degrees, which caused the plane to continue to stall". Subsequently, the airplane impacted the ground.

The airplane sustained substantial damage to the wings and empennage.

The student pilot reported that there were no preaccident mechanical malfunctions or failures 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 student pilot's failure to maintain adequate airspeed and his exceedance of the airplane's critical angle of attack during an attempted go-around, which resulted in an aerodynamic stall.

Findings

Aircraft
Angle of attack - Capability exceeded (Cause)
Airspeed - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Student pilot (Cause)

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.
