This is hardly a stand taken by the DGCA. There are internal forces within Spice which ensured that Capt Singh was removed from his post and replaced with a more 'friendly' person. Anyone with inside info can determine who he has been replaced with and the motivation to have him supplanted.
For the record I have been trained by him and upgraded during his tenure as GM and I have not come across a more practical and no nonsense airman in my short career so far. In a country burdened with archaic laws and slavish adherence to rote SOP's, his attitude and outlook to training was a breath of fresh air and inspired confidence in all trainees who came across him.
Notwithstading this particular incident, DGCA is still a corrupt, incompetent and indifferent organisation in whose hands millions of lives are put in danger. Don't be fooled by this 'action'.
