Kapoor prior to his departure from the Gurgaon-based carrier, was discharging the functions and duties of the Accountable Manager as mandated by the aviation regulator DGCA.
The Gurgaon-based carrier in a communication to the Directorate General of Civil Aviation on Friday informed about Gupta's nomination to the position, sources said.
DGCA mandates Accountable Manager to execute decisions/plans of the organisation and can be nominated from among the Chief Executive, President, Managing Director, Vice President or Deputy Managing Director.
The airline, which is now under the ownership of original co-founder Ajay Singh, does not have Chief Executive Officer since 2013. South African national Neil Raymond Mills was the last chief executive of SpiceJet before he quit in July 2013.
Besides, the airline also does not have a chief commercial officer since the departure of Kaneswaran Avili in April this year.
"The airline has yet to fill these positions," sources said.
The then SpiceJet managing director, S Natrajhen, was the first top executive exiting the carrier soon after Singh came onboard.
A co-founder of SpiceJet, Singh, who exited the airline in 2010, took back its control after acquiring the entire 58.46 per cent stake of Kalanithi Maran and Kal Airways Pvt Ltd in February as part of a revival plan.
