Aerodynamic Stall/Spin: Cessna 182Q Skylane, N96974; accident occurred May 05, 2019 at Marion Municipal Airport (KMZZ), Grant County, Indiana






Aviation Accident Final Report - National Transportation Safety Board

Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Indianapolis, Indiana

Investigation Docket - National Transportation Safety Board:


Location: Marion, IN
Accident Number: GAA19CA246
Date & Time: 05/05/2019, 1712 EDT
Registration: N96974
Aircraft: Cessna 182
Aircraft Damage: Destroyed
Defining Event: Aerodynamic stall/spin
Injuries: 2 Minor, 2 None
Flight Conducted Under: Part 91: General Aviation - Personal 

Analysis 

The pilot reported that, during landing, the airplane landed hard and bounced. He decided to go around, so he added full power, but the nose pitched up sharply. He added that he attempted to lower the nose, but the airspeed decreased, and the airplane "lost lift on [the] right side." He pushed forward on the control yoke, but the airplane drifted right, the right wing aerodynamically stalled, and the airplane impacted the ground next to a taxiway and spun around. A passenger saw a fire in front of the firewall, and all occupants exited the airplane.

The airplane was destroyed by postaccident fire.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

A Federal Aviation Administration (FAA) inspector reported that the pilot stated he used nose-up trim during the approach. The pilot also stated that, during the go-around, he attempted to use the electric trim to trim nose down. When the airplane nosed up, the pilot attempted to lower the nose but hesitated due to the airplane being near the ground, and he retracted the flaps. The FAA inspector examined the airplane and found that the trim setting was "just short of full nose up trim."

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's improper trim setting and his exceedance of the airplane's critical angle of attack during a go-around, which resulted in an aerodynamic stall.

Findings

Aircraft Angle of attack - Capability exceeded
Aircraft Elevator tab control system - Incorrect use/operation
Personnel issues Aircraft control - Pilot
