Grounded carrier Kingfisher Airlines
The airline, owned by liquor tycoon Vijay Mallya and suspended in October over unpaid debts and salaries, submitted a plan on Monday to the Directorate General of Civil Aviation (DGCA) to resume a limited service.
According to local media reports, Kingfisher's parent company, UB Group, offered to inject 6.5 billion rupees into the carrier - a key condition for getting it airborne again.
But Singh told reporters on Wednesday that UB "did not say they are going to give anything" to Kingfisher, which has estimated debts of $2.5 billion.
He did not specify if the proposal, to resume operations with five planes, had been rejected. But he noted that the airline owed money to banks, staff, airports, and tax authorities.
All those stakeholders needed to be convinced the relaunch plan was viable before the DGCA allowed the airline to fly again, Singh said.
Kingfisher, which has been trying unsuccessfully to raise fresh cash for more than a year, is hoping to tap Etihad Airways as an investor.
The Gulf carrier, which is seeking to widen operations in India and other Asian markets, is in the final stages of talks to buy part of either Kingfisher or Indian rival Jet Airways
