I flew for a company in UK back in the 80's who regularly dropped skydivers from a Bell 206. All pilots had to be checked and signed off by an experienced British Parachute Association instructor. The pilot was then issued with a BPA card restricted to the type of aircraft flown during the endorsement.The company operations manual was amended to allow this.
Four skydivers were dropped from between 4 and 10 thousand feet and exited in a planned sequence to help with C of G. All were very experienced display/CRW skydivers. They preferred to exit at a low forward airspeed rather than in a hover.
Finding yourself suddenly all alone at 10,000 feet in a Bell 206 with all doors removed can be disconcerting but the experience was great fun - particularly as the skydivers were all attractive women.
