The DGCA has already started its investigation in the alleged violations and may issue a notice to the two carriers shortly in this regard, official sources said.
"Though the investigation are being carried out, initial probe suggests that the two airlines violated safety norms by going ahead with the landing despite adverse weather conditions," a source said, adding, the DGCA has already called the four commanders of the two airlines, who operated these flights, for questioning.
While Jet Airways, which also flies to Leh, did not operate its flight after receiving the weather forecast, both Air India and GoAir went ahead and landed their flights amid dense cloud conditions and raining, violating safety norms for operations in hilly terrains and thereby endangering the safety of over 575 persons on board, according to sources.
The two Air India flights had 107 and 109 persons onboard respectively while GoAir had 166 and 185 persons respectively onboard its two flights to Leh on June 26.
"However, all the three airlines have been asked to revise their standard operating procedure manual and keep the document updated," the source said.
