Investigation Docket - National Transportation Safety Board:
Klemme Aviation LLC
Location: Davenport, Iowa
Accident Number: CEN20CA253
Date & Time: June 27, 2020, 09:11 Local
Registration: N18873
Aircraft: Beech 23
Aircraft Damage: Substantial
Defining Event: Aerodynamic stall/spin
Injuries: 2 Minor, 1 None
Flight Conducted Under: Part 91: General aviation - Personal
Analysis
The pilot was taking off and had begun to climb out when, the airplane's critical angle of attack was exceeded, an aerodynamic stall occurred, and the airplane impacted terrain. The airplane sustained substantial damage to the fuselage. A postaccident examination of the airframe by Federal Aviation Administration aviation safety inspectors found the trim was configured in a nose up setting for a
landing profile. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe and engine that would have precluded normal operation.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to properly configure the airplane for takeoff, which resulted in the exceedance of the airplane's critical angle of attack, an aerodynamic stall, and subsequent impact with terrain.
Findings
Personnel issues Preflight inspection - Pilot
Personnel issues Aircraft control - Pilot
Aircraft Elevator control system - Inadequate inspection
Aircraft Angle of attack - Capability exceeded
