It'[s an eye opener if you've flown and/or wrenched on airplanes for awhile to look in the accident database and search registration numbers and see what's happened to many of them. Last I checked it was 12 totaled/written off, many with fatalities, thankfully, neither cases with myself involved.
RE: "auto slats". On some occasions the slats on the Helio Courier could deploy asymmetrically. Obviously asymmetric retraction is what you'd want to avoid.
