My wife is one of my volunteers in aviation safety research. She's entering data for me this morning between appointments with the clients at her law firm. She came across one of the cases where the crash was precipitated by an engine failure. The pilot reported to ATC that he had oil all over his windshield. They dropped into trees short of a field where an emergency landing could have been carried out. There was no evidence of the cowling being damaged before they hit the trees. She has the file so I don't remember the exact initial cause of the failure but I remember it involved the structure of the engine fracturing at some point. Her question to me was "Isn't there some way to design the hood of the plane (she didn't know the word "cowling") to keep that from happening?". Aside from making the cowling able to stay on and with a tight seal, I don't have a clue. She goes "Maybe those guys on the airplane forum with have some ideas?" Any ideas fellas?
