“Stalls and spins represent the largest single factor in fatal general aviation accidents.” Surprisingly, this quote wasn’t pulled from the latest FAA news release, but rather from a NASA Langley Research Center newsletter dated April 1977. Forty years later, stall-spins and loss of control remain pinned to the top of the National Transportation Safety Board’s Most Wanted List of safety improvements. That doesn’t mean no one has tried to reduce the number of LOC-I fatalities.
How Wing Cuffs Work
Key Takeaways:
- Stall-spins and loss of control have historically been the leading cause of fatal general aviation accidents, prompting NASA to develop solutions like the leading-edge wing cuff.
- The wing cuff enhances stall-spin resistance by causing the inner portion of the wing to stall before the outer section, thereby maintaining lift and aileron control at high angles of attack and making spins more benign and recoverable.
- Developed by NASA in the late 1970s, this low-cost modification proved effective in preventing abrupt wing drops and leading to a new category of spin-resistant aircraft certification, now implemented on several modern GA aircraft.
