Aviation Accident Preliminary Report - National Transportation Safety Board:

Location: Kenosha, WI
Accident Number: CEN18LA360
Date & Time: 08/30/2018, 1900 CDT
Registration: N64604
Aircraft: Stearman A75N1 (PT17)
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal 

On August 30, 2018, about 1900 central daylight time, a Stearman A75N1 (PT17) airplane, sustained substantial damage when nosed over during the landing roll at the Kenosha Regional Airport (ENW), Kenosha, Wisconsin. The airline transport pilot, who was the sole occupant, was not injured, and the airplane sustained substantial damage to the rudder. The airplane was registered to and operated by a private individual as a Title 14 Code of Federal Regulations Part 91 personal flight. Visual meteorological conditions prevailed at the time of the accident, and a flight plan was not filed. The local flight departed ENW about 1830.

According to the pilot, he had performed three touch and go maneuvers without the use of any braking. On the fourth and last planned landing rollout about 30 mph, the airplane experienced an excessive tail wheel shimmy due to a left brake assembly issue. About 25 mph, the airplane nosed over and came to rest inverted.

Postaccident examination of the airplane by a Federal Aviation Administration inspector revealed the left main wheel/brake assembly was locked, and the wheel/tire could not be rotated. Partial disassembly of the wheel/brake assembly revealed a failed retaining bolt for the brake backing plate, and a crack in the backing plate.
