Mr Drax will give evidence to the inquiry by the Commons Transport Select Committee on Monday, November 5.
Last month, Mr Drax submitted a 12-page report on the proposed changes to the coast-guard service being implemented in the area and their potential impact on search and rescue.
His report concluded that it would be ‘sheer folly’ to cut the Portland helicopter.
He said: “It’s good news and I hope it means they’re taking a critical approach to a decision which could adversely affect the lives of all of who live on, work on or visit the south coast.”
Mr Drax is campaigning to get 100,000 signatures on a petition to save the helicopter. Visit epetitions.direct.gov. uk/petitions/36619 to sign.
