Typically used for fast running landing (such as TR malfunction) and moving helidecks
Never ever had any issues with the 76 on moving helidecks, nor heard of problems. What issues prevail, besides forgetting to lock the brakes?
Only tail wheel locking type I flew was the H-34, locking was only required on parking, running take off/landing or doing an auto. Any student who broke a pin was required to wear it on a lanyard around the neck for a week, I reckon it should have been the instructor who wore it as all trips were dual - inadequate supervision.
