Norman sent the helicopter to the greater Louisiana area Friday, and said it will remain in service for as long as a month. His pilot, Gary Hogan, will fly medical supplies and other items into the region.
'Our thoughts and feelings go out to everyone over there,' Norman said.
Norman's estate on Jupiter Island, about 90 miles north of Miami, was damaged by hurricanes Frances and Jeanne last year. He lent his helicopter - which can carry about 1,000 pounds of supplies and shuttle small groups of patients and medics - to the recovery effort.
The Federal Emergency Management Agency contacted the helicopter's manufacturer in recent days seeking help, and word eventually got to Norman. FEMA will coordinate Hogan's flights and supply fuel.
'They need as much airlift as they can get,' Norman said.
Norman, a former world No. 1 player, was inducted into the World Golf Hall of Fame in 2001. The two-time British Open champion has won 86 tournaments, including 20 on the PGA Tour.
