Struggling Air India might be forced to shut down by June next year unless it finds a buyer as “piecemeal” arrangements cannot be sustained for long, according to a senior airline official.

Amid continuing uncertainty over the fate of the national carrier, the official said there is also need for funds to restart operations of 12 grounded narrow-bodied planes.

The airline has a debt burden of around Rs 60,000 crore and the government is still working on the modalities for the divestment.

Sounding alarm bells, the official said Air India might well go the Jet Airways way if a prospective buyer does not come on board by June next year.

With government leaving the debt-ridden airline to fend for itself by refusing to inject funds any more amid its privatisation plans, the airline is “somehow” keeping it afloat with piecemeal arrangements, which are unlikely to sustain for long, the official said.

According to the government, it has infused funds worth Rs 30,520.21 crore in the flag carrier from financial year 2011-12 till December this year.

Under the turnaround plan approved by the UPA regime in 2012, the airline was to get financial assistance of Rs 30,000 crore over a 10-year period.

“We had sought Rs 2,400-crore sovereign guarantee to mop up funds to meet the operational requirement. But the government has provided guarantee only for Rs 500 crore. We are somehow managing the operations at present and at best we can sustain this situation till June. If a buyer does not come by that time, we will have to shut shop,” said the official on condition of anonymity.
