Years ago probably late 70s early 80s there was a tragic accident with a Puma in Canada caused by BBQ plate failure.
As I recall - BBQ plate failed while the AC was in the hover picking up a longline load.
Transmission torqued to the right which caused the #1 engine drive shaft to be torn loose.
#1 engine over sped and shut down ( this disabled overspeed protection on # 2 engine )
Transmission then torqued left which took out the #2 engine driveshaft. # 2 engine over sped and, due to disabled protection, exploded causing a large fire and crash.
BBQ plate was redesigned and cycle counts for multiple longline sling ops were imposed.
Just mentioned as I am sure the subject may come up.
I am not speculating that BBQ plate failure is a causal factor in this accident.
