Background
The final regulations that are the subject of these amendments were originally codified as:
- Civil Air Regulations (CAR) 7.225 and 7.226, recodified as 14 CFR 29.397, effective February 1, 1965, and later amended by Amendment 29-12, effective February 1, 1977; and
- CAR 6.225 and 6.226, recodified as 14 CFR 27.397, effective February 1, 1965, and later amended by Amendment 27-11, effective February 1, 1977, was intended to establish a maximum pilot force for twist controls of 80R inch-pounds.
However, as published, the final regulations contain an error that has long been recognized by the FAA and industry as being misleading and in need of clarification. When these regulations were previously published, we inadvertently omitted the word “inch” in the phrase “Twist controls, 80R inch-pounds”. These technical amendments clarify that the appropriate measurement is to be in “inch-pounds” not “pounds”.
