Accident occurred Sunday, March 03, 2013 in Angel Fire, NM
Probable Cause Approval Date: 01/30/2014
Aircraft: MOONEY M20E, registration: N3484X
Injuries: 4 Fatal.
NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
Before takeoff, strong, gusting wind from the west was present, so a fixed-base operator (FBO) employee asked the pilot about his intent to fly. He stated that the pilot seemed "confident" about his ability to fly the airplane and that he was not concerned about the wind. As the airplane departed, the reported wind was 33 knots gusting to 47 knots. The FBO employee stated that he saw the airplane "crab" into the wind about 40 degrees right of the runway's heading. The airplane rose and fell repeatedly as its wings rocked. When the airplane was between 75 and 150 feet above the ground, the left wing dropped, and the airplane then rolled left, descended inverted, and impacted terrain in a nose-down attitude. A postimpact examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. A weather research and forecasting model indicated that, at the time of the accident, the accident site was located within a turbulent mountain-wave environment, with low-level windshear, updrafts and downdrafts, downslope winds, and an environment conducive for rotors (that is, a violent rolling wave of air occurring in lee of a mountain or hill in which air rotates about a horizontal axis). The pilot had no prior experience flying out of the accident airport and it was the highest elevation airport he had ever used. In addition, he had limited experience flying in mountainous areas.
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's loss of control while flying in a turbulent mountain-wave environment. Contributing to the accident was the pilot's overconfidence in his ability to safely pilot the airplane in gusting wind conditions and his lack of experience operating in mountainous areas.
HISTORY OF FLIGHT
On March 3, 2013, about 1320 mountain standard time, a Mooney M20E, N3484X, impacted terrain after departing the Angel Fire Airport (KAXX), Angel Fire, New Mexico. The private pilot and three passengers were fatally injured. The airplane was substantially damaged and a post-impact fire ensued. The aircraft was registered to and operated by Verhalen Flyers LLC, Scottsville, Texas, under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight, which operated without a flight plan. The flight was departing KAXX at the time of the accident and was destined to the Dallas-Fort Worth area.
When the pilot arrived at the fixed base operator (FBO), an employee from the FBO questioned the pilot's intent to fly in the windy weather. The pilot indicated that he planned to fly and that the winds would not be a problem. When the pilot radioed on universal communications (UNICOM) that he was taxiing to runway 17, the current wind and altimeter were relayed to the pilot by the FBO employee, which were repeated by the pilot. Due to snow piles on the airfield, the FBO employee could not see the takeoff and next saw the airplane airborne with a significant crab angle into the wind, about 40 degrees right of the runway heading. The airplane rose and fell repeatedly as its wings rocked. Then employee saw the airplane's right wing rise rapidly. The airplane rolled left, and descended inverted with the airplane's nose pointed straight down.
An eyewitness riding in a car along Highway 434, west of the airport, saw the airplane take off from the runway. The witness perceived that the airplane was struggling to gain altitude. When the airplane climbed between 75 to 150 feet above the ground, the airplane appeared to momentarily hover before the left wing dipped quickly and the airplane descended nose first to the ground.
PERSONNEL INFORMATION
The pilot, age 33, held a private pilot certificate for airplane single engine land. On October 13, 2011, he was issued an unrestricted third class medical certificate. On his medical certificate application, the pilot reported having accumulated 380 total hours. The pilot's logbook was not available for review by the investigator. Paperwork filed with the pilot's insurance company reported that as of October 2012, the pilot accrued 459 hours with 384 hour in the same make and model as the accident airplane.
The pilot reported to the FBO manager that he had flown the accident airplane for five years. He added that KAXX was the highest airport that he had landed at, although he had flown to some lower elevation airports in Colorado and Wyoming on previous flights. The pilot's experience flying out of airports with high density altitude is not known.
A cousin of the pilot, who lived in the local area, reported that the night before the accident he had discussed airplanes and the airplane accidents in the Angel Fire area. The pilot reported to him that flying in wind did not bother him.
AIRPLANE INFORMATION
The four seat, low wing, single engine airplane, serial number 1156, was manufactured in 1966. It was powered by a 200-horsepower, fuel-injected, Lycoming IO-360-A1A engine which drove a two-blade, metal, constant speed, Hartzell HC-2YK-1BF propeller. The airplane's log books were almost completely consumed in the post impact fire. Information retrieved from receipts, reported that the airplane's most recent annual inspection occurred on December 7, 2012, at a tachometer and airframe total time of 4,752.65 hours. The engine had accrued 6,859.85 hours, with 1,736.75 hours since major overhaul. At the accident site, the airplane's tachometer read 4,785.84 hours.
METEROLOGICAL INFORMATION
At 1315, an automated weather reporting facility located at KAXX, reported wind from 250 degrees at 33 knots gusting to 47 knots, visibility 10 miles, a clear sky, temperature 47 degrees Fahrenheit (F), dew point 17 F, and a barometric pressure of 29.93 inches of mercury. Utilizing this weather, the density altitude was calculated at 9,549 feet.
KAXX and the accident site were located in a basin nearly encompassed by mountainous terrain. Mountains to the west and northwest of the airport have peaks between 10,470 and 13,160 feet. A weather study was compiled for the accident site. An upper air sound for 1400 mountain standard time (MST) depicted an unstable vertical environment which would allow mixing of the wind on the lee side of the terrain. Winds as high as 55 knots could occasionally reach the surface. Satellite imagery between 1300 and 1400 MST recorded a large amount of standing lenticular cloud near all of the mountainous terrain around the accident site. These clouds indicated the presence of a mountain wave environment. At 0322 and 1134, the National Weather Service issued wind advisories for the accident area that warned of a west of southwest wind between 25 and 35 miles per hour (mph) with gusts to 50 mph.
A Weather Research and Forecasting (MRF) model was created to simulate the accident's weather conditions. The WRF model indicated that the accident site at the accident time was located within a turbulent mountain wave environment, with low-level wind shear, updrafts and downdrafts, downslope winds, and an environment conducive for rotors.
The pilot did not receive a weather briefing and it is not known what weather sources the pilot referenced prior to takeoff.
AIRPORT INFORMATION
The Angle Fire Airport is located at an elevation of 8,380 feet. It has one asphalt runway, 17-35, which is 8,900 feet long by 100 feet wide. The airfield is non-towered and utilizes a common traffic advisory frequency. The departure runway was runway 17, which has a 0.6% upgrade. An Automated Weather Observing System (AWOS-3) is located on airport property.
Information contained in KAXX's airport/facility directory contains remarks for "strong gusty crosswinds possible" and "high density altitude probable."
Located in the airport's FBO were posters and literature warning pilots about crosswinds, mountainous terrain, weight and balance, take off performance, density altitude, and runway 17's upgrade.
WRECKAGE AND IMPACT INFORMATION
The airplane came to rest about 0.2 miles south-southwest of the airport. It was located near the intersection of the runway's extended centerline and Highway 434. The initial impact point was a crater on the highway's shoulder. The crater contained acrylic glass and near the crater was the airplane's propeller. Fifteen feet east of the crater was the main wreckage which was inverted. A postimpact fire consumed a majority of the fuselage and empennage. Both wings remained attached to the fuselage and displayed near symmetric accordion crushing. Both fuel tanks were breached and empty. The left wing's outboard section remained intact, along with its aileron. The inboard portion of the left wing, around the area of the fuel tank, was consumed by fire to include a majority of the left flap. The left main gear was thermally damaged and buckled. The right wing remained mostly intact, with its aileron and flap still attached at their respective locations. The right flap appeared set to 15 degrees. The right main gear was extended. The vertical stabilizer and horizontal stabilizers were buckled, torn, and thermally damaged. Flight control continuity was established from the ailerons to the cockpit controls. The rudder and elevator rods remained connected to their control surfaces until just forward of the vertical stabilizer where fire had destroyed and melted a majority of the control rods.
The airspeed indicator read 81 mph. The attitude direction indicator depicted a left wing low, inverted attitude. The tachometer read 2000 rpm. The altimeter's Kohlsman window read 29.93.
The propeller fractured at the propeller flange. Both blades displayed leading edge nicks and gouges, deep, chordwise scratches, and leading edge polishing.
MEDICAL AND PATHOLOGICAL INFORMATION
An autopsy was conducted on the pilot by the Office of the Medical Investigator of the State of New Mexico. The autopsy noted the cause of death as a result of multiple blunt force injuries. The manner of death was ruled an accident.
Forensic toxicology was performed on specimens from the pilot by the FAA Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma. Testing did not detect ethanol or drugs. Specimens from the pilot were not suitable to test for carbon monoxide; however, specimens from a passenger were tested and did not contain carbon monoxide.
ADDITIONAL INFORMATION
Weight and Balance
An old copy of the airplane's weight and balance, marked "superseded 6/28/02" was located in the wreckage. Utilizing the data contained on the form and information on file with the Federal Aviation Administration, an estimated weight and balance was calculated for the accident airplane. Postmortem weights of the airplane occupants were obtained from the Office of the Medical Investigator. These weights were not corrected for clothing or water loss due to thermal injuries. Occupant seats were assumed in the forward positions for better forward center of gravity (CG). The occupants' baggage was consumed in the postimpact fire and could not be weighed. An estimate of ten pounds per bag was given to the six bags reported to be on the airplane. Twenty-eight gallons of fuel was reported to be in the tanks prior to flight. The airplane's weight was calculated at 2,518.77 pounds with a moment arm of 123.98 inches. This placed in airplane aft of the manufacturer's center of gravity moment envelope.
Excerpts from FAA Aeronautical Information Manual
In Chapter 7, Section 7-5-6, "Safety of Flight, Mountain Flying," the following described hazards to pilots during operation in mountainous terrain.
"High density altitude reduces all aircraft performance parameters. To the pilot, this means that the normal horsepower output is reduced, propeller efficiency is reduced and a higher true airspeed is required to sustain the aircraft throughout its operating parameters."
"Mountain waves occur when air is being blown over a mountain range or even the ridge of a sharp bluff area. As the air hits the upwind side of the range, it starts to climb, thus creating what is generally a smooth updraft which turns into a turbulent downdraft as the air passes the crest of the ridge. From this point, for many miles downwind, there will be a series of downdrafts and updrafts."

Jennifer Woodward was among the people killed in the March 3 airplane crash in Angel Fire.
Jennifer Woodward and John Verhalen
From left, Sarah Verhalen, Chloe Marie Jameson and John Verhalen were among the people killed in an Angel Fire plane crash.
Moreno Valley resident Matt Batchelder said his wife Alison is a distant cousin of the pilot, 33-year-old John Phillip Verhalen III, who died in the crash. The pilot’s 41-year-old sister Sarah Verhalen, her 13-year-old daughter Chloe Marie Jameson, and the pilot’s 26-year-old girlfriend Jennifer Woodward also died in the crash.
Matt Batchelder said the four victims were staying at a local guest house owned by his father. He said he met John and Sarah Verhalen at a family reunion a few years ago.
Matt Batchelder said John Verhalen was an aeronautical engineer and had studied for almost a decade to get into his career.
“I never questioned his decision-making as a pilot,” he said.
Matt Batchelder also said John Verhalen was a “great uncle to his niece.”
“Chloe was really into gymnastics,” he said. “She told me she would train for 15 hours a week. She could walk across the room on her hands.”
Matt Batchelder’s 13-year-old son Stanton Batchelder said he met the Verhalens about five years ago, and he has good memories of them.
“I knew them because they were cousins of my mom,” Stanton Batchelder said. “They were super-duper nice people, and they were always welcoming. We played games a lot together, and that’s how I got to know them.”
“Cranium” was a favorite game among the two families, Stanton Batchelder said.
Matt Batchelder’s last words to the victims before they left: “Come back and visit anytime. Have a safe trip.”
The members of the Verhalen family who died were buried Sunday (March 10) on a family homestead. A memorial service for Woodward is scheduled for March 17 in Schertz, Texas, according to her obituary on the Schertz Funeral Home and Crematory website.
