Is Violation of Safety Norms is the Culprit for the Crash?

Many causes have been put forward for the Air India plane crash in Ahmedabad.
Among others, Captain A. (Mohan) Ranganathan in his article in The Hindu has picked on chronic negligence of safety norms.
Captain Ranganathan says that the civil aviation ministry, the judiciary, the director general civil aviation (DGCA), the airports authority of India (AAI) and the airlines in India-- all have been lax in ensuring stringent training and safety standards.
The claim that India is the fastest growing aviation system has nothing to show due to chronic corruption and manipulation in the system.
Every time an air crash takes place, pilots are blamed.
Though there have been blatant violations of the safety norms set by the International Civil Aviation Organisation, after each crash the civil aviation minister defends the safety standards in place.
The writer alleges that probe officers to investigate the causes of a crash are chosen to ensure that blamed are put at the doors of the pilots. Safety norms were also found be violated in the latest crash.
Our judiciary has also been lagging in ensuring strict adherence to the safety norms. When a PIL was filed after the Mangaluru air crash pointing out violations of the safety norms by all the stakeholders-- the ministry, the DGCA, the AAI and the Air India, the Supreme Court instead of adjudicating it sent the matter to the ministry to check the authenticity of the facts, the writer says. Wait for more facts to come out to have a final picture.
