John McGarrigle is seeking compensation from Bond Air Services which could run to thousands of pounds if successful.
We revealed last year how he had been accused of inventing a relationship with his father to line his pockets with compensation.
The 39-year-old was “devastated” by the claim but last night vowed: “They’re badly mistaken if they think I’m going to walk away.”
Strict liability laws mean the aircraft’s owner is responsible for injuries to ground victims but, despite this, Bond is refusing to recognise John’s claim.
He added: “I’m astonished it’s reached the point where I’m having to take them to court.
“The tactics are despicable and show nothing but contempt for the loss of my dad and his memory.
“I’ve consistently said this is nothing to do with money, it’s about responsibility being taken for what happened.
“We all want clarity in relation to the crash. We also want fault to be recognised and we want to move on with our lives.
“Bond seem determined to do everything in their power to prevent that.”
Last March we exclusively told how lawyers acting for Bond insisted John was estranged from his 57-year-old dad, also John, at the time of the air disaster and should not get a penny.
John Jr insists they were close and had been due to meet the night of the tragedy. He just missed joining his dad in the pub the night disaster struck after his girlfriend was rushed to hospital suffering an asthma attack.
Despite accusing John of fabricating his relationship for financial gain, John claims Bond and lawyers Clyde & Co have produced no evidence to back up their position.
John, who claims his dad was his soul mate, said: “I’ve had to go and get statements from friends to show the relationship I had with my dad.
“They seem to be hell bent on causing me as much pain as they possibly can, and they’ve not come up with a single fact that even comes close to justifying why they are making me do this. It’s appalling the way they’ve treated me. Maybe they think by forcing me into a corner I will just throw in the towel.”
Ten people perished when the police helicopter plunged into the Glasgow riverside pub on November 29, 2013.
In October, an Air Accidents Investigation Branch (AAIB) report concluded pilot David Traill, 51, did not follow emergency protocol and flew on, ignoring low fuel warnings.
It also emerged the helicopter’s fuel transfer pumps were turned off and a controlled landing was not achieved for “unknown reasons”.
Ex-RAF pilot Traill and the helicopter’s crew PCs Tony Collins, 43, and 36-year-old Kirsty Nelis lost their lives.
Pub customers Sam McGhee, 56, Mark O’Prey, 44, Gary Arthur, 48, Colin Gibson, 33, Robert Jenkins, 61, and Joe Cusker, 59, also perished.
In the wake of the AAIB findings the Crown Office confirmed a fatal accident inquiry will be held as soon as possible.
Law firm Irwin Mitchell is acting for John.
The Sunday Post contacted Clyde & Co for a statement, but they had no comment to make.
