JAKARTA (Reuters) – Indonesia authorities extended on Wednesday a search for victims of a plane crash last week, when all 189 on board a Lion Air flight were killed, and for the aircraft’s second black box, the cockpit voice recorder.

The nearly new Boeing Co. 737 MAX passenger plane slammed into the sea on Oct. 29, only minutes after takeoff from Jakarta en route to Bangka island near Sumatra.

“We have extended the operation for three more days,” Muhammad Syaugi, the head of the national search and rescue agency (Basarnas), told Reuters.

It was the second time the search has been extended.

But he said search teams from the military, police and others would stand down, leaving just his agency to press on.

“This operation has been running for 10 days and the results from combing the sea surface and the seabed are declining, therefore the resources of Basarnas should be sufficient,” Syaugi told a news conference.

Basarnas had 220 personnel, including 60 divers, as well as four ships involved in the search and were focusing on an area with a radius of 250 meters (273 yards), he said.

A police official said 186 body bags containing human remains had been retrieved and 44 victims identified after forensic examination.

Authorities have downloaded data from one of the black boxes found last week, the flight data recorder, but are still looking for the cockpit voice recorder

A “ping” has been detected from the second black box but the signal was very weak, possibly because it was encased in mud,” said Nurcahyo Utomo, an air accident official at the transportation safety committee (KNKT).

A vessel capable of sucking up mud was likely to be brought in to help, he told a news conference.

Boeing said on Wednesday it had issued a safety bulletin reminding pilots how to handle erroneous data from a sensor in the wake of the Lion Air crash.

The U.S. planemaker said investigators looking into the Lion Air crash had found that one of the “angle of attack” sensors on the aircraft had provided erroneous data.

Experts say the angle of attack is a crucial parameter that helps the aircraft’s systems understand whether its nose is too high relative to the current of air – a phenomenon that can throw the plane into an aerodynamic stall and make it fall.

KNKT said that there was a problem with the sensor on the last flight taken by the doomed plane, from the island of Bali to Jakarta, even though one sensor had been replaced in Bali.

The KNKT has interviewed crew and technicians on duty for two previous flights, while also retrieving the faulty sensor from Bali for inspection.

KNKT is planning to simulate a flight to assess the impact of sensor damage at Boeing’s engineering simulator facility in Seattle.

Russia finds main black box from Black Sea crash jet

MOSCOW (Reuters) – Russia has found the main flight recorder from a military plane that crashed into the Black Sea killing all 92 on board, the Defence Ministry said on Tuesday, amid unconfirmed reports that authorities had grounded all aircraft of the same type.

The recorder, one of several reported to be on board, contains information that could help investigators identify the cause of Sunday’s crash, which killed dozens of Red Army Choir singers and dancers en route to Syria to entertain Russian troops in the run-up to the New Year.

Investigators have so far said that pilot error or a technical fault, rather than terrorism, are most likely to have caused the Defence Ministry’s Tupolev-154 to crash into the sea.

The black box, which was found by a remote-controlled underwater vehicle at a depth of around 55ft (17 metres) and 1 mile (1,600 metres) from the resort of Sochi, has been sent to a Defence Ministry facility in Moscow for analysis.

“The casing holding the flight recorder is in a satisfactory condition,” the ministry said in a statement.

“After it is technically cleaned in distilled water we will start transcribing it.”

The ministry said numerous fragments of the plane had been found, including the engine, the landing gear and pieces of the fuselage.

The Interfax news agency cited an unnamed source as saying Russia had grounded all TU-154 planes until the cause of Sunday’s crash became clear. There was no official confirmation of that.

The Defence Ministry says the downed jet, a Soviet-era plane built in 1983, had last been serviced in September and underwent more major repairs in December 2014.

Russian pilots say the TU-154 is still flight worthy, though major Russian commercial airlines have long since replaced it with Western-built planes. Experts say only two are registered with Russian passenger airlines with the rest registered to various government ministries.

The last big TU-154 crash was in 2010 when a Polish jet carrying then-president Lech Kaczynski and much of Poland’s political elite went down in western Russia killing everyone on board.

The Interfax news agency, citing a law enforcement source, said a second flight recorder had also been found in the wreckage of Sunday’s crash, but not yet raised to the surface.

The Defence Ministry said that search and rescue teams have so far recovered 12 bodies and 156 body fragments.

French, Italian firms to help search for EgyptAir black boxes

Recovered debris of the EgyptAir jet that crashed in the Mediterranean Sea are seen in this still image taken from video

By Ahmed Aboulenein

CAIRO (Reuters) – Egypt is taking on two companies, one French and one Italian, to help search for the black boxes of an EgyptAir plane that crashed in deep water in the Mediterranean Sea, the airline’s chairman said on Wednesday

EgyptAir flight 804 crashed on May 19 with 66 people on board including 30 Egyptians and 15 from France, and nearly a week later investigators have no clear picture of the plane’s final moments.

EgyptAir chairman Safwat Musallam did not name the companies involved, but he told a news conference they were able to carry out searches at a depth of 3,000 meters.

The plane and its black box recorders, which could explain what brought down the Paris-to-Cairo flight as it entered Egyptian air space, have not been located.

The black boxes are believed to be lying in up to 3,000 meters of water, on the edge of the range for hearing and locating signals emitted by the boxes.

Maritime search experts say this means acoustic hydrophones must be towed in the water at depths of up to 2,000 meters in order to have the best chance of picking up the signals.

Until recently, aviation sources say, the US Navy or its private contractor Phoenix International were considered among the only sources for equipment needed to search on the correct frequency for black box pingers at such depths.

The US Navy said on Tuesday it had not been asked for help.

Batteries powering the signals sent from the black boxes typically last only 30 days, but the airline’s deputy chairman Ahmed Adel said the search would continue beyond then if necessary, using other means to locate the recorders.

“There are many examples in similar air accidents when 30 days passed without finding the box yet … these planes’ black boxes were found,” he said.

‘PLANE’S MACHINES WERE SAFE’

Musallam reiterated earlier comments from sources within the Egyptian investigation committee who said that the jet had shown no sign of technical problems before taking off from Paris.

He said the Airbus 320 was given a regular check by an Egyptian engineer and two Egyptian technicians at Paris airport.

“The engineer and the pilot both signed the Aircraft Technical Log which stated that the check found that all the plane’s machines were safe,” he said.

The investigation sources said the plane disappeared off radar screens less than a minute after entering Egyptian airspace and – contrary to reports from Greece – there was no sign that it had swerved sharply before crashing.

The crew did not make contact with Egyptian air traffic control, they said.

With no flight recorders to check and only fragmentary data from a handful of fault messages registering smoke in the plane in the minutes before it crashed, investigators are also looking to debris and body parts for clues.

One Egyptian forensics official said the small amount of human remains recovered pointed to an explosion on board though no trace of explosives had been detected.

But Hisham Abdelhamid, head of Egypt’s forensics authority, said this assessment was “mere assumptions” and that it was too early to draw conclusions.
