Accident Number: CEN18LA335
Date & Time: 08/16/2018, 1100 MDT
Registration: N146AC
Aircraft: Cessna R172E
Aircraft Damage: Substantial
Defining Event: Unknown or undetermined
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Instructional

On August 16, 2018, about 1100 mountain daylight time, a Cessna R172E, N146AC, sustained substantial damage during a forced landing after takeoff from the USAF Academy Airfield (AFF), Colorado Springs, Colorado. The flight instructor and student pilot were not injured. The airplane was owned and operated by the United States Air Force under the provisions of Title 14 Code of Federal Regulations Part 91 as an instructional flight. Visual meteorological conditions prevailed at the time of the flight, which was not on a flight plan. The flight was departing from AFF on a local flight.

The flight instructor reported that the preflight and run-up were normal. He stated that he intended to stay in the traffic pattern to practice landings. He reported that the student pilot was flying the airplane during takeoff from the 4,480 ft by 75 ft asphalt runway. The engine was operating properly with a fuel flow of about 14 gallons per hour and 2,800 – 2,900 rpm, and the engine sounded normal. During the takeoff roll, the student pilot rotated about 60 mph. Initially, the pitch was high but then she lowered the nose to the horizon. The flight instructor reported that the airplane attained about 100 ft of altitude above ground level; however, the airplane was not climbing, and the airspeed was decreasing with normal fuel flow and rpm. The flight instructor took the controls, lowered the flaps to 10°, and lowered the nose to hold 55 – 60 mph, "hoping that the ground effect would enable a speed increase." He turned the airplane to the right to avoid a tree line and executed a forced landing in a field. The airplane landed on its main wheels, but the nose landing gear impacted rough terrain and the airplane nosed over, resulting in substantial damage to the wings and fuselage.

The airplane's maintenance logbooks indicated that the last annual maintenance inspection was performed on January 7, 2018. The airplane had a total time of 10,571.8 hours with an engine hour meter indicating 1,566.6 hours. The engine logbook indicated that the engine had been installed on the airplane during the last annual maintenance inspection on January 7, 2018. The engine was a 210 horsepower Continental IO-360-DB, serial number 808785-R, with a rated rpm of 2,800 rpm. The engine had 5,680.1 hours total time and 0.0 hours since major overhaul. The tach time on the day of the accident was 1,634.9 hours and it had operated 68.3 hours since the last annual inspection.

The engine was shipped to the manufacturer for an examination and an engine run in a test stand. During the initial engine run, the engine was able to reach full rpm and produced rated horsepower; however, during subsequent engine runs, it only reached 2,600 rpm. The fuel system was checked, and it was determined that two fuel nozzles were partially clogged. The fuel nozzles were cleaned, and the engine was run again on the test stand. The engine operated normally and reached approximately 2,830 rpm. The engine power was reduced to idle speed and advanced to full throttle several times. The engine responded without hesitation and reached over 2,800 rpm each time the throttle was advanced to full throttle.

The propeller governor was shipped to the manufacturer for bench testing. The examination and bench test of the propeller governor revealed no indications of any type of governor failure or malfunction prior to impact, and the governor met all the tested specifications.

The 58-year-old pilot held an airline transport certificate with airplane single-engine land, airplane multi-engine land, and airplane instrument ratings, as well as being a flight instructor pilot with airplane single-engine, airplane multi-engine, and airplane instrument ratings. He had a total of 17,631 flight hours which included 2,469 hours in single-engine airplanes, and 20 hours in make and model of the accident airplane.

At 1058, the surface weather observation at AFF was: wind 360° at 9 knots; visibility 10 miles; few clouds at 17,000 ft; scattered clouds at 20,0000 ft and 22,000 ft; temperature 26° C; dew point 6° C; and altimeter 30.29 inches of mercury.

On August 16, 2018, about 1100 mountain daylight time, a Cessna R172E, N146AC, sustained substantial damage during a forced landing after takeoff from the Air Force Academy Airfield (AFF), Colorado Springs, Colorado. The instructor pilot and student pilot were not injured. The airplane was owned and operated by the United States Air Force under the provisions of Title 14 Code of Federal Regulations Part 91 as an instructional flight. Visual meteorological conditions prevailed at the time of the flight, which was not on a flight plan. The flight was departing from AFF on a local instructional flight.

The instructor pilot reported that the preflight and runup were normal. He reported that the student pilot was flying the airplane during takeoff from runway 34 (4,480 ft by 75 ft, asphalt). The engine was operating properly with a fuel flow of about 14 gallons per hour and 2,800 – 2,900 RPM, and the engine sounded normal. The student pilot rotated about 60 mph. Initially, the pitch was high but then she lowered the nose to the horizon. The airplane attained about 100 ft above ground level; however, the airplane was not accelerating or climbing. The instructor pilot took the controls and lowered the nose, but the airplane continued to descend, and he turned 10° to the right to do a forced landing in a field. The airplane landed on its main wheels, but the nose landing gear jammed into the rough terrain and the airplane nosed over.

At 1058, the surface weather observation at AFF was: wind 360° at 9 knots; visibility 10 miles; few clouds at 17,000 ft; scattered clouds at 20,0000 ft and 22,000 ft; temperature 26° C; dew point 6° C; and altimeter 30.29 inches of mercury.

A recreational aircraft flipped on its top during an emergency landing Thursday morning at Interstate 25 and Interquest Parkway, according to a news release from the Air Force Academy.

The Cessna R172E Cutlass was carrying two people when it went down, one of which was a contracted instructor pilot, the academy said. Neither person was injured.

The Air Force did not explain what caused the emergency landing. The weather forecast at the time showed partly cloudy skies with wind speeds of 23 mph.

Federal Aviation Administration records show the aircraft was manufactured in 1967 and is owned by the United States Air Force, but Air Force spokesman Meade Warthen says it's not used for operational purposes, only recreational. The plane is maintained by the Aero Club, a civilian-owned flying club located at the Air Force Academy.

"Those airplanes are not there for any other purpose than for people to rent or fly them" Warthen said.

He did not believe the plane had previously been involved in a crash.

The club is run by certified flight instructors and maintains five aircraft, including one T-41B and four Cessna 172 planes, their website says. Club members — cadets, active duty, military members, retirees and contractors — can take courses to earn basic private pilot certificates or more advanced certificates, it says.

The aircraft can be rented for personal use for about $100 an hour.
