On January 25, 2017, about 1730 central standard time, a Cessna 172 airplane, N5639A, impacted trees and terrain during a forced landing following an inflight loss of engine power near Jay, Oklahoma. The private pilot was fatally injured. The airplane was substantially damaged. The airplane was owned by Mexico Medical Missions and was operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Day visual meteorological conditions prevailed at the time of the accident and no flight plan was filed. The flight departed from a private airstrip near Jay, Oklahoma, and was destined for the Grove Municipal Airport (GMJ), Grove, Oklahoma.

According to initial information from a manager at GMJ, the pilot purchased 9.56 gallons of 100 low lead aviation gasoline (avgas) at 1019 on January 24, 2017.

According to a witness at the departure airstrip, the pilot intended to fly the airplane to GMJ. He saw the pilot service the airplane with fuel from fuel cans. He saw the pilot put fuel into both of the airplane's fuel tanks. He saw the pilot taxi up and down the runway multiple times. He saw the airplane subsequently depart and he drove to GMJ to pick up the pilot. When the pilot did not arrive, he reported the airplane as missing. Law enforcement conducted a search for the airplane. The emergency locator transmitter signal was detected and a helicopter spotted the airplane in a field near a tree line.

The 61-year-old pilot held a Federal Aviation Administration (FAA) private pilot certificate with an airplane single engine land rating. He also held a FAA third-class medical certificate that was issued on August 23, 2016, with no limitations. The pilot reported on his application for his medical certificate that he accumulated 450 hours of total flight time with 1 hour in the six months preceding his medical.

N5639A, a 1956 model Cessna 172, Skyhawk, serial number 28239, was an externally braced high-wing, propeller-driven, fixed landing gear, semi-monocoque design, four-seat airplane. A 145-horsepower, six-cylinder, air cooled, horizontally opposed, carbureted, Continental O-300 engine, marked with serial number 11594-D-6-B, powered the airplane. The propeller was a two-bladed, all-metal, fixed pitch, McCauley model 1A170/DM765, with serial number 62885. Airplane logbooks revealed the last recorded annual inspection was completed on July 3, 2008. An endorsement for that inspection indicated that the airplane tachometer indicated 2,817.4 hours and the airplane had accumulated 5,739.4 hours of total time. The airplane was not equipped with a shoulder harness and was not required to have one installed.

At 1735, the recorded weather at GMJ was: Wind 290 degrees at 7 knots; visibility 10 statute miles, sky condition clear; temperature 6 degrees C; dew point -2 degrees C; altimeter 29.96 inches of mercury.

The airplane was found inverted on approximately a 40 degree heading about 7 miles and 214 degrees from GMJ in an open field with hay rolls scattered throughout the field. The airplane came to rest near a tree line that bounded the western edge of the field. The first found tree with a broken branch was observed about 125 feet and 267 degrees from the wreckage. There were broken and separated branches with signs of recent breaks observed aloft in trees and on the ground from that first found tree towards the wreckage. Sections of clear plastic consistent with the landing light lens were found along that same path to the wreckage along with chips of paint consistent with the color of the airplane. The left wing had a semicircular depression in its leading edge between its landing light and its wing tip. The size of a separated tree branch was consistent with the size of the shape of the semicircular depression.

All of the airplane's control surfaces remained attached to the airplane. Flight control cables were traced and fight control cable continuity was established. No cable separations were observed. The elevator trim control cable was continuous from the trim wheel chain to the trim actuator and its trim tab arm was attached to the trim tab. The flap system's control cables were continuous from its flap actuator bar to the flaps' bellcranks. The bellcranks' push/pull rods were connected to their respective flap. The extent of flap deployment could not be determined due to the post impact damage. The elevator trim was about 1.3 inches, which equates to a position of about five degrees tab trailing edge down. The elevator trim indicator was observed in the take-off range.

The engine was found displaced rearward into the firewall. The propeller blades did not exhibit any chordwise abrasions or leading edge nicks. One propeller blade was bent rearward. The carburetor was found separated from its mounting flange.

Fuel system was found intact except for a separated line near the left fuel tank. About six gallons of a blue colored liquid consistent with the smell and color of avgas was recovered from the right fuel tank. About two gallons of liquid consistent with avgas was recovered from the left fuel tank. There was some liquid consistent with avgas found in the carburetor bowl and in the firewall mounted strainer bowl. All found and recovered liquid samples were tested for water contamination using water paste and no water contamination indication was observed. The fuel valve selector handle was found in the right tank position. There was no securing pin installed in the selector handle. Pressurized air was applied to the main fuel line at the firewall and air discharged from the left tank's fuel line. Fuel tank caps were removed. The right tank cap was a vented cap. A vacuum was applied to the cap's vent and no obstructions were noted. The left tank cap was a non-vented cap. The left tank vent was observed and no obstruction were present on its intake screen.

The tachometer indicated 2,848.03 hours and the Hobbs meter indicated 1,137.8 hours. The ignition switch key was broken and a section of key was retained within the switch. The switch was in the "Both" position. The master switch was found in the "On" position. The primer was found in a forward position; however, it was not locked. The mixture and throttle were in their forward positions. The carburetor heat was found in its off position.

The Delaware County Coroner was asked to arrange for an autopsy to be performed on the pilot and to take toxicological samples.

The engine and separated carburetor will be shipped to the engine manufacturer for a detailed examination.

GROVE — Bob Hudson would travel for miles, sometimes on foot, to take medical supplies and the gospel to the Tarahumara Indians in Mexico's Copper Canyon.

Bob and Pam Hudson spent the past five years as medical missionaries to Mexico, flying in supplies from their home on Grand Lake.

On Wednesday, Bob Hudson, 61, died when the Cessna 172 he was piloting crashed into a field near Zena in Delaware County, minutes after taking off from a grassy runway. The plane lost power, and Hudson was trying to make an emergency landing when the plane struck a tree, according to the Oklahoma Highway Patrol.

Bob and Pam Hudson

Hudson had just left his friend Alvin Lee; they had been talking about missionary work.

The Cessna had recently been donated to the Hudsons' Mexico Medical Missions, Lee said.

“I waved at him and watched him take off,” Lee said. “I was going to drive into Grove and pick him up at the airport.”

It was a 10-minute flight from Lee's airstrip to the Grove Regional Airport. When Hudson failed to arrive, friends began searching on their four-wheelers. An OHP aircraft spotted the wreckage in a field between Lee's home and State Highway 127, Lee said.

Hudson had been a pilot for seven years. He retired as a land surveyor from Rose & McCrary, a Grove engineering and land surveying business.

Mexico Medical Missions provided health care, food, shelter, clean water and educational aid, according to a brochure. The Hudsons lived in Mexico and were planning to return in about two weeks, Lee said.

The father of four and grandfather of eight was described as a former pastor, a loving husband, a great missionary and a good friend by messages posted on social media sites.

The Tarahumara Indians live at an altitude of about 8,000 feet, Lee said. The roads are poor. The airplanes make it easier to visit the villagers and to take the sick among them to the hospital.

Hudson had several aircraft based at the Grove airport over the years, said Lisa Jewett, airport manager.

"His heart was always about medical missions and his faith in Jesus was important to him. He shared his faith with everyone," Jewett said.

“He retired just so he could do medical missions. He was such a great and honorable man. He will be missed by so many," Jewett said.

“How do you come to grips with such a tragic and sudden loss of a man who, along with his lovely wife Pam, gave so much to help desperately poor people in the far interior of Mexico,” said Doug Anderson, a friend.

"Those he selflessly helped, those he left behind and all the many lives he influenced in such a positive way, will feel his death," Anderson said.

The OHP said the Federal Aviation Administration and the National Transportation Board are investigating the crash.
