AirAsia Flight 8501 did not have permission to fly to Singapore on the day it crashed into the Java Sea, transport officials have said as search chiefs said they had found “two big objects” believed to be from the missing plane. 
 
 AirAsia’s Airbus 320 disappeared around 40 minutes after taking off from the Indonesian city of Surabaya last Sunday morning with 162 people on board. 
 
 However, the company was only authorised to fly that route on Mondays, Tuesdays, Thursdays and Saturdays, Indonesia’s transport ministry said. 
 
 "It violated the route permit given, the schedule given, that's the problem," Djoko Murjatmodjo, the head of air transport, told AFP on Saturday. 
 
 It was not immediately clear why AirAsia had been flying that day if it did not have permission. All the company’s flights from Surabaya to Singapore have now been ordered to stop. The transport ministry has announced a full review of all AirAsia flights. 
 
 Sunu Widyatmoko, the chief executive of AirAsia’s Indonesian subsidiary, confirmed government officials had suspended the airline’s permission to fly from Surabaya to Singapore but declined to comment further. 
 
 Meanwhile search teams operating in the Java Sea reported detecting an oil slick and “two big objects” believed to be parts of the plan’s main fuselage. 
 
 “With the oil slick that we found and the discovery of the two big objects, I can confirm that this is the big part of the AirAsia plane we have been looking for all this time,” Bambang Soelistyo, the head of Indonesia’s search and rescue agency, told reporters. 
 
 Teams of divers were expected to explore those objects on Saturday, weather permitting. 
 
 As the search entered its sixth day, with around 60 vessels and 20 aircraft now involved, there was renewed speculation that “extreme weather” had contributed to south-east Asia’s third major airline catastrophe of 2014.

 A 14-page "meteorological analysis" from Indonesia's Meteorology, Climatology and Geophysics Agency said one likely scenario was that icing, caused by bad weather, had “damaged” the Airbus’s engines. 
 
 "This is however just one analysis of what likely happened based on available meteorological data, and is not the final determination on the cause of the incident,” said the report, quoted by Singapore’s Straits Times newspaper. 
 
 Tony Fernandes, the AirAsia chief, has hinted extreme weather played a major role in the tragedy. “What we are beginning to see is that there were some very unique weather conditions,” he said earlier this week. 
 
 “I continue to have full faith in our operations in Indonesia and elsewhere,” he added. 
 
 As Indonesian rescue teams flew the bodies of 12 more victims back to Surabaya for identification and burial, heart-breaking reports emerged about a 15-year-old Indonesian girl who lost her entire family in the tragedy.

 Chiara Natasya Tanus, a Surabaya-born student who was attending school in Singapore, lost both parents and both brothers - aged 17 and 9 - in the crash. They had been coming to visit her for New Year's Eve and when they did not arrive at Sinagpore airport as expected last Sunday she returned home to her dormitory. 
 
 “We were supposed to have the best time in Singapore - we planned to spend the rest of holidays together,” the orphaned teenager told Indonesia’s Jawa Pos newspaper. 
 
 “I was so excited. I was looking forward to showing my dormitory to my family,” she added. ||||| Jakarta, Indonesia (CNN) Searchers have located a majority of AirAsia Flight QZ8501's fuselage in the Java Sea, the head of Indonesia's search and rescue agency said Wednesday, raising the prospect that many bodies of the 162 people aboard the flight that crashed last month will soon be found. 
 
 The confirmation follows major developments in the investigation of the disaster -- the recoveries earlier this week of the plane's flight data and cockpit voice recorders. 
 
 Searchers saw the plane's main body, with one of its wings attached, via a camera carried by a remotely operated underwater vehicle, Indonesia search chief Bambang Soelistyo said. 
 
 Key in identifying the debris are the words painted on the section. Pictures released by the search agency appear to show portions of the words "now" and "everyone." 
 
 AirAsia says the slogan "Now everyone can fly" had been on the length of the plane, which crashed December 28 as it flew toward Singapore from the Indonesian city of Surabaya. 
 
 Divers will search the fuselage for bodies Thursday, and if the divers encounter trouble, crews may lift the fuselage out of the water, Soelistyo said. 
 
 Officials didn't mention the depth of the water. But officials have said other debris, such as the recorders -- which were found about a half mile from the fuselage on Monday and Tuesday -- were discovered at a depth of roughly 30 meters (100 feet). 
 
 At least 50 bodies have been recovered from the sea, Soelistyo said. Some were strapped into seats. 
 
 Officials have said that many of the more than 100 remaining bodies might be found in or near the plane's fuselage. 
 
 The majority of the people on Flight QZ8501 were Indonesian. Citizens of Britain, France, Malaysia, Singapore and South Korea also were aboard. 
 
 Soelistyo said the discovered portion of the fuselage is about 100 feet long. That would represent the majority of the Airbus A320-200, which was about 120 feet long. 
 
 Authorities don't know why the plane crashed. Roughly 35 minutes into the flight, the pilot asked air traffic control for permission to turn left and climb to avoid bad weather. Minutes later, the plane disappeared from radar. 
 
 'Black boxes' may contain answers 
 
 On Tuesday, divers retrieved the cockpit voice recorder, which is designed to retain all sounds on a plane's flight deck. 
 
 A day earlier, searchers recovered the plane's other key information source, the flight data recorder, which stores a vast amount of information about the aircraft's performance, including air speed and cabin pressure. 
 
 Both devices are expected to help investigators understand what went wrong. 
 
 The flight data recorder tells investigators what happened on a plane, but the cockpit voice recorder tells them why, said Mardjono Siswosuwarno, a senior official at Indonesia's National Transportation Safety Committee, which is leading the investigation into the disaster. 
 
 "The 'why' is mostly in there," he said of the voice recorder, which captures conversations between pilots, as well as other sounds in the cockpit. 
 
 Analysis of data to take months 
 
 The two flight recorders were taken to a lab in Jakarta, the Indonesian capital, for analysis. 
 
 Investigators say they have successfully downloaded the contents of both devices. But Mardjono cautioned that interpreting the information requires much more time. 
 
 After the download, investigators should have "a pretty good idea within a couple of days" of what happened aboard the plane, Mary Schiavo, a former inspector general of the U.S. Department of Transportation, said this week. 
 
 The flight data recorder usually contains hundreds of parameters and thousands of data points, she said, that look a bit like an electrocardiogram when they're printed. 
 
 Mardjono said he expected a preliminary report to be released within a month of the crash. 
 
 But it's unclear how much information the initial document will contain beyond what's already been made public. The final report containing investigators' full conclusions will take months, Mardjono said. 
 
 The agency's final report into Adam Air Flight 574 -- which crashed in Indonesian waters on New Year's Day 2007, killing all 102 people on board -- came out more than a year after that disaster. 
 
 Mardjono said the AirAsia plane's flight data recorder was in good condition after being pulled out of the water from under the debris of a wing Monday. 
 
 Did plane break apart on impact? 
 
 The recovery of the recorders took place after the plane's tail was lifted from the waves Saturday. 
 
 Observers have suggested that the locations of the different parts of debris indicate the plane broke apart when it hit the water, not when it was still at a high altitude. 
 
 One Indonesian search official, who goes by the single name of Supriyadi, said that the debris patterns suggest the aircraft "exploded" on impact. 
 
 But the country's transportation investigators said it was premature to say what had happened, and one expert questioned the search official's choice of words. 
 
 "The word 'exploded' I think maybe loses a little bit in translation," said David Soucie, a former Federal Aviation Administration safety inspector. "I think really what he's meaning is a rupture from the impact itself. 
 
 "As with any hollow object hitting something very hard, the pressure differential between the outside and the inside is very significant, and it'll actually tear apart the aircraft on the top," Soucie said. "That may be what he's referring to." ||||| JAKARTA/PANGKALAN BUN, Indonesia Search teams hunting for the wreck of an AirAsia passenger jet that crashed with 162 people on board have found four large parts of the plane on the sea bed, the head of Indonesia's search and rescue agency said on Saturday. 
 
 A multi-national task force of ships, planes and helicopters have been scouring the northern Java Sea and coastline of southern Borneo to recover the bodies of victims and locate the wreck of Flight QZ8501 and its black box flight recorders. 
 
 "We've found four big parts from the plane we're looking for," search and rescue agency chief Fransiskus Bambang Soelistyo told reporters in Jakarta. 
 
 The breakthrough came as authorities said that Indonesia AirAsia had violated the terms of its licence for the Surabaya to Singapore route by flying on a Sunday, the day the Airbus A320-200 plunged into the Java Sea, and announced they would investigate the carrier's other schedules. 
 
 One large object was pinpointed by a ship searching during the night, Soelistyo said, and three more, the largest of which was around 18 metres long, were located on Saturday. 
 
 Another official, Supriyadi, who is coordinating the operation from the port of Pangkalan Bun in Borneo, said earlier that poor visibility had hampered efforts to capture images of the objects with underwater remote operating vehicles (ROVs). 
 
 "The visibility is only two metres," he said. "It's cloudy, making it difficult for the cameras to detect." 
 
 Divers, including a team of Russian specialists who just arrived in Pangkalan Bun, may be able to investigate the suspected wreckage on Sunday if the weather improves, officials said. 
 
 NO SURVIVORS 
 
 No survivors have been found from the crash, which happened about 40 minutes after the plane took off from Indonesia's second largest city in an area known for intense tropical thunderstorms during the current monsoon season. 
 
 A report from Indonesia's weather bureau said it was likely the plane had flown into bad weather which would have been difficult to avoid, and that it was possible this had caused ice to form on its engines. 
 
 "Based on the available data on the last received location of the aircraft, the weather was a factor in causing the accident," the weather bureau said. 
 
 Indonesian authorities on Friday questioned whether the pilot had followed correct weather procedures, and later suspended Indonesia AirAsia's Surabaya to Singapore flights, saying the airline's operating licence only permitted flights on Mondays, Tuesdays, Thursdays and Saturdays. 
 
 Djoko Murdjatmodjo, Indonesia's acting Director General of Air Transportation, said on Saturday that the Transport Ministry would investigate other routes used by the carrier, which flies from at least 15 Indonesian destinations. 
 
 "We are going to investigate all AirAsia flight schedules. Hopefully we can start on next Monday," he said. "It is possible AirAsia's licence in Indonesia might be revoked," he added. 
 
 Sunu Widyatmoko, Indonesia AirAsia chief, told reporters the airline, which is 49-percent owned by Malaysia-based AirAsia, would cooperate with the inquiry. 
 
 "The government has suspended our flights from Surabaya to Singapore and back," he said. "They are doing the evaluation process. AirAsia will cooperate fully with the evaluation." 
 
 Much effort has focused on finding the mostly Indonesian victims of the crash. Thirty bodies have been recovered from the sea, although rescue official Supriyadi, who like many Indonesians uses just one name, said it was unlikely more would be found floating. 
 
 "Because we're already in the seventh day ... the chances are they have all sunk," he said. "There's a possibility they'll be found on beaches." 
 
 Small pieces of the aircraft and other debris have also been found, but there has been no sign of the crucial voice and flight data recorders - the so-called black boxes that investigators hope will unravel the sequence of events in the cockpit during the doomed jet's final minutes. 
 
 WEATHER FACTOR 
 
 The cause of the crash, the first fatal accident suffered by the AirAsia group, remains unexplained. 
 
 The plane was flying at 32,000 ft (9,753 metres) and the pilot had asked to climb to 38,000 ft just before contact was lost. When air traffic controllers granted permission to fly at 34,000 ft a few minutes later there was no response. 
 
 A source close to the investigation said radar data appeared to show the aircraft made an "unbelievably" steep climb before it crashed, possibly pushing it beyond the A320's limits. 
 
 Hadi Mustofa Djuraid, a transport ministry official, told reporters on Friday that authorities were also investigating the possibility that the pilot did not ask for a weather report from the meteorological agency at the time of take-off. 
 
 Indonesia AirAsia said in a statement that weather reports were printed in hard copy at the operations control centre at all its flight hubs, including Surabaya, and taken by the pilot to the aircraft before each flight. 
 
 An AirAsia spokeswoman declined to comment on whether the pilot had followed the procedure described in the statement.

– Search teams in Indonesia may have found the main fuselage of the AirAsia plane where most of the remaining victims and the plane's black boxes are expected to be. Authorities found "four big parts of the plane we're looking for," says the official in charge of the search in the Java Sea, reports Reuters. The biggest of the pieces is about 59 feet long and 18 feet wide, reports AP. The pieces have only been detected, not recovered, and divers hope conditions will permit them to reach the objects tomorrow. So far, only 30 of 162 bodies have been recovered, and most of the victims are believed to be still strapped in their seats. Authorities also said today that AirAsia was in violation of its license by flying to Singapore on a Sunday, the day of the crash, reports the Telegraph. As a result, the airline might have its license revoked in Indonesia. There's still no conclusions yet in what caused the crash, but theories continue to center on stormy conditions. "Flight 8501 appears to have been trapped in bad weather that would have been difficult to avoid," says a report by Indonesia's Meteorology, Climatology and Geophysics Agency.
