Pilots struggled to control plane that crashed in Indonesia: Report
Jakarta, Nov 28 : Black box data show Lion Air pilots struggled to maintain control of a Boeing jet as its automatic safety system repeatedly pushed the plane's nose down, according to a draft of a preliminary report by Indonesian authorities investigating last month's deadly crash.
The investigators are focusing on whether faulty information from sensors led the plane's system to force the nose down. The new Boeing 737 MAX 8 plunged into the Java Sea on October 29, killing all 189 people on board, including an Indian pilot.
Information from the Lion Air jet's flight data recorder was included in a briefing for the Indonesian Parliament. Indonesian authorities were due to release the findings Wednesday but not to draw conclusions from the data they present.
Peter Lemme, an expert in aviation and satellite communications and a former Boeing engineer, wrote an analysis of the data on his blog.
The MAX aircraft, the latest version of Boeing's popular 737 jetliner, includes an automated system that pushes the nose down if a sensor detects that the nose is pointed so high that the plane could go into an aerodynamic stall.
Lemme described "a deadly game of tag" in which the plane pointed down, the pilots countered by manually aiming the nose higher, only for the sequence to repeat about five seconds later.
That happened 26 times, but pilots failed to recognize what was happening and follow the known procedure for countering incorrect activation of the automated safety system, Lemme told The Associated Press.
Lemme said he was also troubled that there weren't easy checks to see if sensor information was correct, that the crew of the fatal flight apparently wasn't warned that similar problems had occurred on previous flights, and that the Lion Air jet wasn't fixed after those flights.
"Had they fixed the airplane, we would not have had the accident," he said. "Every accident is a combination of events, so there is disappointment all around here," he said.
Boeing did not immediately respond to two emails and a phone call requesting comment.
The company said last week that it remains confident in the safety of the 737 MAX and had given airlines around the world two updates to "re-emphasize existing procedures for these situations."
Pilots at American Airlines and Southwest Airlines complained this month that they had not been given all information about the new system on the MAX. More than 200 MAX jets have been delivered to airlines around the world.
The Indonesian investigation is continuing with help from US regulators and Boeing. Searchers have not found the plane's cockpit voice recorder, which would provide more information about the pilots' actions.

Speculation over Nitish Kumar’s Rajya Sabha entry roils Bihar; Giriraj calls it ‘Holi prank’
Patna (PTI): Bihar was abuzz with speculation on Wednesday over rumours that JD(U) president and the state’s longest-serving Chief Minister Nitish Kumar may move to the Rajya Sabha, paving the way for the BJP to take the top post while accommodating his son Nishant as deputy CM.
However, senior BJP leader and Union minister Giriraj Singh dismissed the rumour as a "Holi prank", asserting "Nitish Kumar ji is the chief minister".
The filing of nomination papers for five Rajya Sabha seats in the state will close on Thursday.
While the BJP has named its two candidates, including national general secretary Nitin Nabin, and confirmed a second consecutive term for junior NDA ally Upendra Kushwaha, the JD(U) is yet to officially announce its nominees.
The rumours of Kumar, who turned 75 earlier this month, being one of the candidates of JD(U), surfaced a day after the party had announced that his son Nishant would be making a belated entry into politics.
Earlier, there were speculations that the reclusive Nishant, who is in his late 40s and is yet to be formally inducted into the JD(U), could be sent straight to the Rajya Sabha.
However, with less than 24 hours left for filling of nomination papers, several media outlets ran reports claiming that the chief minister, who has been at the helm since 2005, could choose the Rajya Sabha route to make an "honourable exit".
According to these unconfirmed reports, the BJP, which has been outperforming the JD(U) in elections, will have its own CM in the only Hindi heartland state where the highest seat of power has eluded it.
These reports also suggested that as a bargain, Kumar could settle for the deputy CM's post for his son.
When Giriraj Singh, who represents Begusarai Lok Sabha seat in the state, was approached with queries, he said, "Today is Holi. Such pranks are common on the occasion. Nitish Kumar ji is the chief minister".
JD(U) MLC Sanjay Kumar alias Gandhi ji, a close aide of the party supremo, reacted with bewilderment when his response was sought to the rumours.
"We have no information about who will be the Rajya Sabha candidates of the party. There is an impression that Union minister Ram Nath Thakur may retain his seat, but that is also not official. As regards the other seat, it is a decision to be taken by the chief minister, who is known to reveal his cards at the eleventh hour. We cannot say anything on the reports in the media," he said.
