Larry & all, This could be a serious safety concerns on the structural integrity of the KR design, such as the decision to use wood for the Spar. My concern is that the aging of wood would likely to take a toll on the material strength.... Has anyone did static or dynamic load tests on the structural integrity of the wing/spar of the KR2 planes, say after 20+ years of completion, especially when sitting in the garage or storage area with uncontrollable humidity conditions....?!
Since it costs money, I believe no individual builders of KR2 were willing to perform any such structural tests at a loss of thousands of dollars...?! Sadly, the safety issues of homebuilt aircrafts have brought my serious concerns after seeing so many accidents since I bought my KR2 project early last year! I just attended a funeral of my dear friend and my hangar mate at KAEG, Randy Reimer yesterday. Randy just finished his Glasstar in less than three years ago and crashed his brand new aircraft on his second trip (from Albuquerque to Milwaukee) a couple of weeks ago. Randy and his wife Susie flew from Albuquerque to Milwaukee to attend their nephew's wedding in early October, and he crashed his plane on their returning trip due to loss of control about 11 minutes after took off from Milwaukee on the 12th of October... https://youtu.be/9bbjuJxpOq0 It is extremely sad to see so many fatal accidents happened within short period of time in the GA sector. Something must be done or changed within the homebuilt community, in my humble view in order to bent the accident curve downward?! My suggestion is to seriously consider the installation of BRS in homebuilt aircrafts, and let's first start to explore and experimenting this idea within our KR2 community perhaps? I will be more than happy to see some of us to join hands to do something in order to find answers to questions below: (1) what's the easiest or minimum modifications and cost effective installation design necessary to install a BRS on a typical KR2 structural? (2) what are the best choices or options of parachute or BRS system on the market that we can purchase or use in order to minimize the cost while assuring effective reduction of risk in case of a loss of control emergency at or above 500ft altitude...? I believe a few thousand $ of investment for safety insurance of homebuilt aircraft owners will be well worthy of the money spent. Any thoughts or suggestions on the best approach to improve safety in the homebuilt community with reasonable spending of private resources?! Flying high and stay safe!
