NEW DELHI — Many of India’s airlines are rife with safety violations, according to an unreleased report by the industry’s top regulator here.

Most of the airlines in India — including Air India Express, GoAir, IndiGo, Jet Airways, Kingfisher and SpiceJet — were named in the report, which was dated Dec. 27.

The report was given to The New York Times on Monday by an airline executive, who asked to remain anonymous because the report was not public and he feared repercussions.

The report noted that the regulatory agency, the Directorate General of Civil Aviation, had been prompted to examine the airlines amid a “background of severe financial stress being faced by almost all” of the carriers.
