Analysis

The former world war ii bi-plane trainer had made a wheel landing on the hard surfaced runway. The pilot stated the airplane yawed to the left due to a light lefthand crosswind. He stated he applied some right rudder to compensate for the yaw. Shortly after right rudder application the airplane nosed over inverted onto the runway. The pilot stated he has made hundreds of landings in the airplane and stated it's an '...airplane you cannot relax with on landings.' According to the pilot, the airplane was equipped with larger wheels and brakes. The larger wheels and brakes are normally found on another world war ii training airplane that weighs approximately 1330 pounds more than the accident airplane. The federal aviation administration (FAA) aircraft records branch did not locate a record of an FAA form 337 for this installation.
