En-Route
About 3% of new homebuilts suffer an accident during the first 40 hours.Now show us when most of the homebuilt accidents occurred. That would be in the first 50 hours of time when the aircraft is in the testing phase. If you remove those the accident rate is vastly lower!
Beyond that, it depends on your definition of "vastly". Here's a plot showing the aircraft total time for EAB accidents in the 1998-2022 time period.
Note that this plot shows the hours on the aircraft WHEN accidents occurred. In roughly 50% of all homebuilt accidents, the aircraft had 200 hours or less. Understand, this is NOT saying that "The average homebuilt has an accident by 200 hours." IF an accident happens, there's a 50% chance the plane had 200 hours or less.
About 5% of accidents occur to planes on their first flights or with two hours or fewer on their tachs. About 18% of accident aircraft had 40 hours or fewer.
I looked at first-flight accidents about eight years ago....

Builder error is a major factor in first-flight accidents.
