The Directorate General of Civil Aviation will conduct a detailed inquiry into the incident, they said.
The visibility was 6 km, which is "more than that required", when the ill-fated plane landed in Mangalore, Airports Authority of India Chairman V P Agarwal told reporters in Delhi hours after the mishap.
"There was no distress indication from the pilot of the ill-fated plane," he said.
Replying to a volley of questions, Agarwal said, "No constructional deficiencies were noticed" and that authorities had conducted all necessary safety checks at the airport before the runway became operational in 2006.
In Mumbai, Air India's director (operations) Anup Srivastava said the plane overshot the runway after it landed at the airport, resulting in the mishap.
Eight passengers of the ill-fated plane from Dubai survived the crash.
"There were 160 passengers, including four infants, and six crew on board the plane. Eight persons survived the crash," he told reporters.
Agarwal said the visibility at the airport was "very good" but the situation deteriorated later.
Srivastava said it had started raining when the mishap took place.
The Air India official said the commander of the plane was 53-year-old Z Glusica, a British national of Serbian origin. He had 10,000 hours of flying experience and his licence had been endorsed by the Directorate General of Civil Aviation, making him "capable" of flying in India.
Glusica had been flying in India for the last two years, Srivastava said, trying to dispel the impression that he was not aware of Indian conditions.
The co-pilot, H S Ahluwalia, who hailed from Karnataka, was relatively new as he had begun flying in April last year. He had 3,750 hours of flying experience.
Glusica and Ahluwalia had last flown to Mangalore on May 17, Srivastava said.
The plane was two-and-a-half-year old and was air-worthy, the Air India official said.
