I was looking through the FAA incident database, and I saw this exact aircraft has had three incidents in the last 3 years, the first occured in July 1999. The pilot was in cruise and he experience severe engine vibration, so he powered back and there was no decrease in vibration. Soon after that the propeller departed the airframe! the second incident in January 2001 was a hard landing that bent the gear, firewall, etc.... And the third incident occured in August of 2001, where the pilot was climbing out of Glendale, AZ and he experienced vibrations and, again, the propeller left the body. Now, is this somthing that the Katana has been designed to do in "response" to extreme vibration, or is this a very weak prop? Also, in both of the incidents where the prop left, the pilot was able to land in the desert with no injuries.
