India's aviation regulator Directorate General of Civil Aviation (DGCA) said on Friday that the revival plan involving an investment of Rs. 650 crore of Kingfisher Airways is not enough for restarting the company's operations.

Kingfisher Chairman Vijay Mallya had filed the revival plan proposing the fresh investment to get planes back in regular service. The regulator believes that the proposal does not include any plans for repayment of dues to the airports in the country and may not be enough to ensure reliable services.

It is believed that Mr. Mallya met Mr. Shrivastava to explained company's plans to reduce debt and pay off various parties including Airports Authority of India (AAI). The airline is applying for the revocation of suspension of its Scheduled Operator's Permit (SOP) or flying license. The DGCA had announced its decision to suspend the airlines licence. The employees of the company have been waiting for their salaries for seven months and the management has only made repeated promises about all payments being cleared soon.

Mr. Mallya has said that the airline has submitted a detailed plan to the DGCA for permission to resume services using its seven planes by the beginning of 2013 for summer schedule. The company plasn to expand operations to 21 places soon.
