Jakarta , Indonesia ( CNN ) The Indonesian military said Tuesday that it was stopping its efforts to recover the remains of AirAsia Flight QZ8501 almost a month after the commercial jet crashed into the sea . Indonesia 's search and rescue agency , Basarnas , will continue its work to try to retrieve bodies from the wreckage site in the Java Sea , the head of the agency , Bambang Soelistyo , said Wednesday . The military provided the majority of personnel and hardware involved in the recovery operation , which was hindered by bad weather and technical problems . `` We are really disappointed , '' Imam Sampurno , whose four family members who were on the plane still have n't been found , said of the military 's announcement . `` We really hope the evacuation process is still going . '' Basarnas said it would have 60 divers , eight salvage experts , seven boats , two helicopters and a fixed-wing plane taking part in the continued search efforts , which will resume Saturday after the teams take a rest . Flight QZ8501 went down on December 28 as it flew from the Indonesian city of Surabaya toward Singapore with 162 people on board . So far , searchers have managed to recover 70 bodies from the sea , leaving 92 still unaccounted for . Over the weekend , navy divers tried to lift part of the fuselage of the plane using wire ropes and giant balloons . But the attempts failed after lines attached to the wreckage broke . An effort to lift a smaller piece of wreckage was also unsuccessful , the military said . `` Our main priority is to find the bodies . We are not going to focus on lifting the fuselage , '' Soelistyo said Wednesday about the future search plans . The chief of the Indonesian armed forces , Gen. Moeldoko , on Tuesday ordered the military teams involved in the operation to pull out , said military spokesman Manahan Simorangkir . Officials said that 19 of the 81 navy divers working on the recovery efforts had fallen ill with decompression sickness and would be taken for treatment at a hospital in Jakarta , the capital . `` I told them safety first . But as we know , soldiers , they are always working hard to find the bodies , '' said Rear Adm. Widodo , commander of the Indonesian Navy 's western fleet . `` They are not thinking about safety but about doing their duty . '' The divers have n't been able to see any more bodies inside the wreckage of the fuselage , Widodo said . Officials had previously suggested that many of the missing human remains might be found inside the fuselage . But Widodo said some bodies could be trapped or hidden under wreckage on the seafloor . Searchers have recovered at least 14 bodies from the fuselage site , including some that floated free during attempts to lift the wreckage , according to officials . Indonesian aviation investigators are still trying to establish why Flight QZ8501 went down in an area of heavy thunderstorms last month while other planes nearby completed their journeys safely . Investigators are looking at whether the aircraft 's flight augmentation computers ( FACs ) played a role in what went wrong , the news agency Reuters reported Tuesday , citing two unidentified people familiar with the matter . The FAC helps pilots with the stability and control of the aircraft , keeping it on course at the proper altitude and making sure adjustments to the rudder are smooth . It also warns pilots if they try to manually push the plane beyond its capabilities . Flight QZ8501 , an Airbus A320-200 , had two FACs , one serving as a backup . Indonesian officials have said the aircraft climbed rapidly before it fell into the water . The reason for the sharp ascent is unclear , but aviation analysts say the FAC could have recognized trouble and , at a critical moment , automatically shifted full control back to the pilots who may not have realized it amid the crisis . Investigators have submitted their preliminary report into the crash , officials said Tuesday . But authorities have said they do n't plan to release it to the public . Indonesian Transportation Minister Ignasius Jonan told CNN on Monday that the final report into the disaster should be published in less than a year . `` It wo n't be a year , that 's my promise , '' he said . CNN 's Pamela Boykoff reported from Jakarta , and Jethro Mullen wrote from Hong Kong . CNN 's Saima Mohsin and Tom Foreman , and journalists Masrur Jamaluddin and Rudy Madanir contributed to this report .
Indonesia 's search agency says it will have 60 divers and 7 boats . The military chief orders his teams to pull out of the wreckage area . Investigators are reportedly looking at whether on-board computers played role in crash .
