The wheels, lifted by crane of turbulent waters, were the largest pieces of remains found so far of the new Boeing 737 Max 8 that disintegrated at high speed impact Shortly after takeoff on Monday. The shattered fuselage of Flight 610 lay across a large field of debris on the ocean floor, the search officers said.
Many bodies were also found in the area, officials added, including some still tied to their seats.

the Memory unit of the flight data recorder., one of the two so-called black jet boxes, was retrieved by divers on Thursday from mud at a depth of about 100 feet. The second black box, the cockpit voice recorder, had not been located on Friday and officials said four announcers were looking for their pings.
"Yesterday I heard two [pings], but one was weak, "said Muhammad Syaugi, the head of the search and rescue agency." But since then, there has been no ping. "
The beacons are designed to emit signals for at least 30 days.
Officials said that more sensitive US detection equipment was being implemented. UU To help find the cockpit voice recorder. Both registrars are considered crucial in determining what caused the accident.
The accident investigators said on Friday they were preparing to open the memory unit, which officials said was taken out of its shell by the impact of the crash. The long process involves precise steps to dry it and clean it.
"The black box is not in normal conditions [and] we were worried that the data could be damaged, "said Haryo Satmiko, deputy head of Indonesia's National Transportation Safety Committee." This morning we cleaned it and the opening process is ongoing. "
US experts and Singapore are attending.
The flight data recorder stores at least 25 hours of detailed information on the operation of the aircraft systems. In a modern aircraft such as the 737 Max 8, it would record more than 1,000 parameters ranging from the basic speed and altitude to the position of the flight control surfaces and the flight control inputs of the crew.
The length of the recording and the short nature of the flight could allow investigators to also review the actions taken by the crew on a previous flight on Sunday from Bali to Jakarta unless the data is erased, as it happens at some point.
A spokesman for the Indonesian air traffic controller said the pilot of that flight requested and received a priority landing in Jakarta. Lion Air said the flight had experienced what was called a "technical problem" that was resolved.
The data collected by Flightradar24, a flight tracking network, indicated that the plane found possible erratic readings of speed and altitude both on the flight from Bali and on the flight that crashed.
Herson, head of the airport authority for the Bali area, said the plane had experienced a problem before the flight on Sunday night, but that it was resolved and that the pilot chose to fly to Jakarta. Mr. Herson, who has only one name, did not give details about the problem.
Indonesia has a history of aviation disasters, and its carriers had a long-standing restriction to fly to the US UU and Europe for security reasons. The last restrictions were lifted in June of this year.
