Location: Chatham, IL
Accident Number: CEN20CA182
Date & Time: 05/15/2020, 1520 CDT
Registration: N120MZ
Aircraft: Cessna 120
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Personal 

The pilot was conducting a visual flight rules (VFR) cross-country flight flying at 5,500 ft mean sea level (MSL) above a cloud layer, and airplane was not equipped with an attitude indicator or flight instruments to operate in instrument meteorological conditions. According to the pilot, the weather was forecast VFR at her destination. While en route, a cloud layer above her started lowering, so she descended to 5,000 ft MSL. The pilot could see blue sky between the layers when the two layers started coming together and the she inadvertently entered instrument meteorological conditions (IMC).

The pilot transitioned to an "inside instrument scan", turned on carburetor heat, and added full power to attempt to climb to find VFR conditions. After climbing 300 to 500 ft and about 5 minutes after entering the clouds, the pilot noticed a right turn had developed as confirmed on the heading indicator and her electronic flight device. The right turn became tighter, and the pilot recognized she was disoriented and descending. She elected to perform corrective action for a nose low unusual attitude and attempted to descend to visual flight conditions. The airplane broke out of the clouds about 1,500 ft above the ground (AGL) in a 25 to 30° right bank and 10 to 15° nose low.

The pilot recovered to level flight and added full power. The airplane would not accelerate above 60-65 knots in level flight and the pilot felt the rudder was ineffective. The pilot elected to conduct a precautionary landing to nearby field that was muddy due to recent rains. During the landing, the airplane flipped over when the wheels dug into the ground. Examination of the airplane revealed flight control continuity to all flight control surfaces and the carburetor heat selector was in the "on" position. The pilot reported the airplane was operating normally prior to entering IMC conditions.

No injuries were reported after a small plane crashed Friday afternoon into an open field north of Chatham.

The plane crashed into a field north of Mansion Road near Wagon Ford Road around 3:19 p.m., Sangamon County Sheriff Jack Campbell confirmed.

The 24-year-old female pilot and a 12-year-old female passenger were enroute from St. Louis to Chicago.

“She came on cloud cover and was not able to fly the plane on instruments,” Campbell said. “She dropped down below the cloud cover and evidently she was too low to the ground, and she had a crash landing in the field.”

Though the plane flipped over and ended up upside down in the wet field, both occupants emerged with no reported injuries.

The Sangamon County Sheriff’s office, Chatham police and fire departments and the Illinois State Police responded to the scene.

The Federal Aviation Administration is investigating the incident.
