"The committee has submitted its report," the DGCA said in a statement on Monday.
The proceedings of the committee were partly held in the open and partly in-camera as per the request of the affected family, it said.
"The findings of the committee prima facie indicate inappropriate handling of passengers by the Indigo staff thereby resulting in certain non-conformances with the applicable regulations," it mentioned.
In view of this, it has been decided to issue a showcause notice to the airline through its authorised representative to explain as to why suitable enforcement action should not be taken against them for the non-conformances, it said.
However, on 9 May, the airline had clarified boy was denied boarding as he was "visibly in panic". However, airline has been provided an opportunity for personal hearing as well as for making written submissions in next ten days from today i.e. till May 26, 2022.
