We looked at details of the five accidents summarized above for this article. There are others we could have chosen, with different lessons. One thing that jumped out at us: Simple singles werent well-represented. Is that because a simple single, say, a Cessna 172, is more maneuverable and better suited to completing a circling approach than an Aerostar? Possibly. But its also possible pilots dont fly simple singles into conditions low enough to require circling as often as they do other airplanes.
