Nigel, was the S76 with Jeff?
I agree that generally the problem is less dramatic with wheels, although I did partner a pilot on a gravity survey around Tom Price who managed to break (separate) skid tubes on a JetRanger on two different days
The first time he came back after an hour or so, the second time he just kept on landing every 4 minutes for 6 hours on the broken skid. Hmmmmm
Wheels: one QHI got a bit enthusiastic during downwind fast stops at Predannack and managed to remove the Wessex tailwheel, and part of the rear fuselage, whilst wracking it around. Hovered at Culdrose for some time until a baggage trolley was pressed into service.
Malarky Jim (where is he these days?) did a fine job hovering a Whirlwind HAS7 for a tyre change after I got a bit enthusiastic on the brakes during an engine off
Previous mention already made about low level filming & skid tubes!!
