Recovery teams have found the tail of the crashed AirAsia Flight 8501 in the Java Sea, the Indonesian search chief says.
"We have successfully obtained part of the plane that has been our target. The tail portion has been confirmed found," search and rescue agency chief Bambang Soelistyo told reporters in Jakarta.
The discovery on the seabed, 11 days after flight 8501 disappeared, could mark a breakthrough in the search as the tail of a plane usually houses the "black box" flight data recorders, crucial to determining the cause of a crash.
The plane vanished from radar screens during a storm on December 28 when it was flying from the city of Surabaya to Singapore with 162 people on board, most of them Indonesian.
Despite a huge recovery operation assisted by various countries, progress has been patchy with poor weather conditions hampering the search. So far 39 bodies have been found, all of them floating on the sea.
Search chiefs earlier said five large parts of the plane had been detected but had not confirmed which parts of the aircraft.
Indonesia alleges the plane was flying on an unauthorised schedule when it crashed and AirAsia has since been suspended from flying the Surabaya-Singapore route.
Indonesia's transport ministry earlier fired one transport official and disciplined several others in a crackdown following the crash, as it investigates how the flight was able to depart without permission.
"To date, we have taken action against eight officials - two from the transport ministry, four from state navigation operator AirNav, and two airport officials," transport ministry official Hadi Mustofa told AFP.
"One of the transport ministry officials was fired and the other official was temporarily suspended. As for the other six officials, some have been temporarily suspended and some have been transferred."
AirAsia Indonesia has declined to comment on allegations it violated its permits. Singapore authorities say the Sunday flight schedule had been cleared at their end.
Mustofa said the ministry was checking all domestic airlines for any other flight violations and would announce its findings later this week.
At Pangkalan Bun, a town on the island of Borneo with the airstrip closest to the crash site, aircraft were preparing to conduct aerial searches in the hope of spotting bodies and debris.
Dozens of military and search officials gave their salute to coffins containing the latest recovered bodies as they were carried by pallbearers to an air force plane.
The two small coffins, topped with bouquets of flowers, were due to be taken to Surabaya, where a crisis centre has been set up to identify bodies.
An initial report from the Indonesian meteorological agency BMKG has said weather was the "triggering factor" of the crash, with ice likely damaging the plane's engines.
But it remained unclear why other planes on similar routes were unaffected by the weather.
