The choppers of the firm were expected to be taken on lease to be deployed in Naxal affected states to assist security forces and the Home Ministry had issued a Letter of Intent (LoI) in this regard last year.
Official sources said following the withdrawal of the operating permit of Global Vectra, the Home Ministry has decided to put on hold its plan to hire the helicopters from the company.
It will now have to look for other private firms for hiring the helicopters.
The Ministry has also sought legal opinion whether it can now hire choppers from other operators in the consortium of bidders which also includes another private firm UTair.
DGCA today suspended the operating permit of Global Vectra Helicorp Limited whose promoter Ravi Rishi is under the CBI scanner in the controversial Tatra truck deal with the army.
The new choppers, once hired, would have been deployed to assist in the deployment, reinforcement and casualty evacuation of troops of the CRPF, ITBP, BSF and state police personnel involved in counter-Maoist operations.
At present, four MI-17 helicopters of the Indian Air Force (IAF) along with few from the Pawan Hans stable are deployed for similar duties in the Naxal operations grid.
The ALH Dhruv fleet has already been grounded by the government after it met with accidents.
