 |
|
On Monday after Oshkosh, my CJ was tied down on a farm strip west of Chicago when a pretty nasty storm system came through at speeds up to 90MPH with "positive" lightning. I happen to be driving on the road when it came through and my Buick was a handful on dark country roads.
My airplane was tied down next to the crop dusters but seemed OK after the storm. Later I found that the swivel on one of my tiedown stakes had straightened out, unwrapping the steel. My gust locks were still on. There were some small indentations on the tail fairing, which is soft metal but no other appartent damage. The Left wing seems a bit heavy so I'll have to correct with trim tabs.
My belief in good gust locks is reinforced. While I do sell them, many folks make their own. Just be certain that the load from the control surfaces is evenly spread to the aircraft structure, not concentrated to a spot, or bolt type lock. Allow for a bit of flexibility in your design and use weather-resistent materials.
