Homebuilt Accidents: Passing The Engine Baton

When looking at homebuilding magazines from the ’60s and ’70s, one factor that stands out is the engine selection: Most were using the small Continental engines, from the A65 to the O-200. The main reason was availability. These engines were used by the thousands in the American lightplane industry after WW-II. As planes like Piper […]

Homebuilt Accidents: Captains Vs. Fledglings

Considerable insights can be gained by examining aircraft accident statistics. But sometimes—well, the results aren’t earth-shattering, but can be interesting nonetheless. Take the issue of pilot experience. We would certainly expect more-experienced pilots to make fewer mistakes. But what’s the actual difference? It’s not something that’s only relevant to homebuilts. But my Experimental/Amateur-Built aircraft accident database […]

Where Have All the Homebuilts Gone?

Most of you probably remember the heady days of the early 2000s, when every year saw the FAA’s listing of the total number of homebuilt aircraft rise by a thousand airplanes or more. Every year, excited articles were triggered when the Experimental/Amateur-Built (E/A-B) fleet size expanded. “We’ve hit 30,000 E/A-B! 32,000! 33,000!” Haven’t seen such […]

Homebuilt Accidents: Fatal Factors

To the owner of an Experimental Amateur-Built (E/A-B) aircraft, any accident is a tragedy. However, the FAA monitors the homebuilt accident rate based on fatal accidents only. It’s understandable, in some ways. Unlike owners of production aircraft, builders of homebuilt aircraft are usually very familiar with disassembling and transporting a bent bird. A minor enough […]
