...Which reminds me of a question I've had since I was a little baby helicopter pilot: Why *doesn't* a 212 have droop stops?
Droop Stops are all well and good, provided they are working properly. If not, we end up back to the start of this thread "Safety" Procedures. As you are obviously used to helis with droop stops fitted, you might have experienced a droop stop failure during shut down. How did you find out first? Was it when the ramp handler signalled that the stops had failed, did you look in the side mirrors (if fitted) and check, or was it when one of the blades sailed past the window several feet lower than the others?
Again we get back to the good old "airmanship" principles, or CRM as it is now known. As with the tie down, unless you use your eyes to verify everything that should be checked, then something will jump out and bite.....
