The student had been specifically briefed about the possibility of confusion, but Robinson identified this as a potential problem in 1981. Human performance discussion, go. The usual suspects will have a pop at Robinson, but let’s not forget how it’s possible to start a 109 with the rotor brake selected on and it only grabs once hydraulic pressure builds as the rotor speeds up…
I'm surprised more attention wasn't given in the report to where the mixture guard actually was, in this case, and how the mixture control was easily accessible. As the report states, this issue has been known for 44+ years! I'm sure this will result in an interesting conversation with the insurance company.....
