A dramatic landing gives student pilot a unique perspective: Diamond DA20-C1 Eclipse, New Horizons Aviation Inc., N979DC; accident occurred January 19, 2015 in Shipshewana, Newbury Township, LaGrange County, Indiana

January 19, 2015, is a day that will forever live in the mind of Jordan Stoltzfus, a sophomore aviation student at Hesston College.

On that day, Stoltzfus survived total engine failure of an airplane, followed by an emergency landing, and lived to tell about it–an experience that not many pilots, seasoned veterans or otherwise, would ever be able to relate to.

Only four days prior to the accident had Stoltzfus, then a senior at Westview High School (Topeka, Ind.), taken his first solo flight in hopes of eventually attaining his private pilot’s license.

This love for flight took wing from a young age. Stoltzfus says he always dreamed of flying as a kid. From airshows with his dad to aspiring to be an astronaut in the third grade, becoming a pilot was truly “the dream.”

And so, New Horizons Aviation in Goshen, Ind., seemed like the perfect place to start aviation training. It would give Stoltzfus a head-start as he headed into Hesston College’s aviation program on a soccer scholarship for the 2015-2016 school year.

“It was a cold, January day,” Stoltzfus said. “I had maybe eleven flight hours under my belt and I was on my own.”

Soon after takeoff, the engine started causing trouble. The cause would later be uncovered: a chunk of ice in front of the air filter. That was all. But in the moment, all Stoltzfus could do was follow routine procedures and hope for the best.

The best didn’t happen, and soon Stoltzfus was proceeding with an emergency landing in his neighbor’s yard.

And then he blacked out.

“The next thing I remember was coming to and there was no glass broken, the cockpit was in one piece, and I wasn’t in any pain. I got up and walked away. It was a miracle.” 

Awakening to find himself unscathed, Stoltzfus then saw his dad and neighbor hurrying over. 911 was on their way with an ambulance. But after a quick examination, Stoltzfus was given the okay and headed home, not a mark on his body to prove the accident had happened.

“It was a miracle–a God thing,” Stoltzfus remarks as he relives the accident in his mind.

Yet, even though his physical appearance had not altered, Stoltzfus’ emotional state, along with those of his parents, was a different story.

“I still get worked up talking about it,” Stoltzfus said. “The next couple of days [after the accident], I struggled with PTSD. It took pills to put me to sleep at night.”

“My mom would break down,” notes Stoltzfus.

And his dad? The day of the accident, he hadn’t even known his son was out on a flight. Putting the pieces together while running over to the scene of the accident was gut-wrenching.

But even with the trauma of the experience still living inside him, Stoltzfus took to the air just two weeks after the accident. While he admits that he was on edge for his first solo flight after the accident, Stoltzfus says that each flight got better and better.

It has been two years and counting since the accident, and Jordan Stoltzfus is only a few months from graduating from Hesston College with his aviation degree, having completed the private, instrument, commercial, and instructor/multi-engine courses.

Dan Miller, aviation director at Hesston College, speaks to Stoltzfus’ success: “Jordan is a talented individual, who continues to develop his risk management decision-making experiences. Enhanced caution is definitely within Jordan’s mindset.”

When asked how he sees the accident affecting the kind of pilot Stoltzfus is becoming, Miller says, “This question has an ongoing answer as the kind of pilot Jordan is becoming continues to develop. His aviation experiences are strengthening Jordan’s personal character as he carries himself with professional confidence.”

And so, Stoltzfus continues to use the dramatic experiences of the past to set him apart as a pilot.

When asked how this experience has changed him, he quickly said, “You don’t know what it’s like until you fly solo and your engine quits. I had an experience that no one [in the Hesston aviation program] has had. That experience will help land me a job.”

And what’s after Hesston College for Stoltzfus? He chuckled and said, “I’ve got a job at New Horizons Aviation. I’m going back to where it all started.”

One more Lark has left his mark, and now heads for the skies.

NTSB Identification: CEN15LA106
14 CFR Part 91: General Aviation
Accident occurred Monday, January 19, 2015 in Shipshewana, IN
Probable Cause Approval Date: 03/17/2015
Aircraft: DIAMOND AIRCRAFT IND INC DA 20 C1, registration: N979DC
Injuries: 1 Uninjured.

NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The student pilot reported that he was practicing solo ground reference maneuvers about 1,600 ft above ground level when the engine began operating erratically. He further stated that the airplane might have entered an aerodynamic stall. He advanced the throttle to full forward, but the engine did not respond and subsequently experienced a total loss of power. He attempted to restart the engine by completing the emergency procedures that he remembered. The engine “turned over” but did not restart. He then prepared for a forced landing to a nearby field. During the base-to-final turn, he lost control of the airplane, and it descended to the ground. The airplane impacted the field and continued into a propane tank and then a house where it came to rest. 
A postaccident examination of the airplane revealed that most of the induction air filter was obstructed by ice; no other anomalies were noted. The engine was test run with and without the ice in the air filter, and the engine produced full power under both conditions. The alternate air lever, which selects a second induction air intake in case the primary air intake (air filter) becomes restricted, was found in the “off” position. The aircraft flight manual states that, in the event of an in-flight engine failure, the alternate air control should be opened (or “on”). A Federal Aviation Administration advisory circular warns pilots of induction system icing known as “impact ice,” which can build up on components like the air filter when moisture-laden air is near freezing. Based on the near-freezing outside air temperature and clouds in the area in which the flight was operating and the lack of any apparent engine malfunctions, it is likely that the primary air induction system became obstructed with impact ice during the flight. 

When asked about the airplane’s alternate air lever, the student pilot indicated that he was unfamiliar with the lever and did not know its intended use. If the student pilot had opened the alternate air control during the initial power loss, it is likely that engine power would have been restored. 

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The total loss of engine power due to impact ice obstructing the primary air induction system, which resulted from the student pilot’s failure to operate the alternate air control. Contributing to the accident was the student pilot’s lack of knowledge about using the alternate air control during an engine power loss. 

On January 19, 2015, about 1700 eastern standard time, a Diamond Aircraft Inc. DA 20 C1 airplane, N979DC, made a forced landing into a field near Shipshewana, Indiana. The solo student pilot was not injured and the airplane sustained substantial damage. The airplane was registered to and operated by New Horizons Aviation Inc. under the provisions of 14 Code of Federal Regulations Part 91 as a solo instructional flight. Visual meteorological conditions prevailed and no flight plan was filed. The local flight departed from the Goshen Municipal Airport (GSH), Goshen, Indiana about 1645. 

According to the student pilot, he was about 1,600 feet above ground level practicing ground reference maneuvers. He reported that the engine operation became erratic and the airplane might have entered an aerodynamic stall. He advanced the throttle to full forward, but the engine did not respond and experienced a total loss of power. He attempted to restart the engine by completing the emergency procedures that he remembered. The engine "turned over" but did not restart. He then prepared for a forced landing into a nearby field. During the base to final turn, he lost control of the airplane and descended to the ground. The airplane impacted the field and continued into a propane tank and then a house where it came to rest. 

The student pilot reported having accumulated 12 total flight hours, all of which were logged in the preceding 30 days, and in the same make and model airplane. 

The airplane was a two seat, low wing, tricycle landing gear, training airplane which was manufactured in 2005. It was powered by a 125-horsepower Continental Motors Inc. IO-240 engine, which drove a Sensenich two-bladed, fixed pitched, wooden propeller. 

On January 22, 2015, the airplane was examined after the accident by a Federal Aviation Administration (FAA) Inspector and a representative from Continental Motors Inc. The examination revealed that the majority of the induction air filter was covered with ice. The alternate air lever in the airplane was OFF. The engine cylinders each displayed normal operating signatures. The spark plugs displayed normal wear signatures when compared to a Champion Aviation Service Manual No. AV6-R. Internal crankshaft continuity was established by rotating the propeller. Additionally, all four cylinders displayed thumb suction and compression. The top spark plugs and ignition leads were reinstalled for an engine operational test run. The air filter remained impacted with ice during the first engine run; the engine was capable of running with the throttle full forward and produced about 2,200 RPM which is normal for a fixed pitch propeller. The alternate air lever was moved to ON and the engine was still capable of producing about 2,200 RPM. The engine was then shut down and the ice removed from the air filter. The engine was subjected to a second test run; the engine produced 2,200 RPM with the throttle advanced to full forward. The ignition switch was actuated to test both magnetos and the decreases in RPM were normal and the engine indications displayed normal operating parameters. Other than the ice in the air induction filter there were no anomalies noted that would have precluded normal operation. The airplane sustained substantial damage to the fuselage and empennage. 

During the postaccident investigation, the pilot was asked about the airplane's alternate air lever. He reported that he was unfamiliar with the lever and did not know its intended use. He also stated that he flew through some low clouds during the flight, but they did not obstruct his view of the ground and he was able to maintain visual flight rules (VFR) the entire time.

At 1653 the weather observation station at GSH, which was located 13 miles southwest, reported the following conditions: wind from 200 degrees at 3 knots, visibility 10 miles, few clouds at 12,000 feet, temperature 36° Fahrenheit (F), dew point 30° F, altimeter setting 29.94 inches of mercury.

Using the average temperature lapse rate, 3.5° F per 1,000 feet, the temperature at 1,600 feet would have been about 30° F. 

The Diamond Aircraft Airplane Flight Manual (AFM) stated in Chapter 7.9.2 Engine Controls: The alternate air control selects a second induction air intake in case of restriction of the primary air intake (air filter). 

AFM Chapter 3.3.1 (c) Engine Failure during Flight – ENGINE RUNNING ROUGHLY – the pilot should perform the following checklist:

1. Mixture – FULL RICH

2. Alternate Air – OPEN

3. Fuel Shut-off – OPEN

4. Fuel Pump – ON

5. Ignition Switch – cycle L – BOTH – R – BOTH

6. Throttle – at present position

7. No Improvement – reduce throttle to minimum required power, land as soon as possible. 

FAA Advisory Circular 20-113. The Advisory Circular states that one form of induction system icing is impact ice and states in part:

"Impact ice is formed by moisture-laden air at temperatures below freezing, striking and freezing on elements of the induction system which are at temperatures of 32° F or below. Under these conditions, ice may build up on such components as the air scoops, heat or alternate air valves, intake screens, and protrusions in the carburetor. Pilots should be particularly alert for such icing when flying in snow, sleet, rain, or clouds, especially when they see ice forming on the windshield or leading edge of the wings. The ambient temperature at which impact ice can be expected to build most rapidly is about 25° F, when the super cooled moisture in the air is still in a semi liquid state. This type of icing affects an engine with fuel injection, as well as carbureted engines. It is usually preferable to use carburetor heat or alternate air as an ice prevention means..."
