Lion Air pilots fought to keep control of their Boeing jet as an automatic security system in the Boeing jet, repeatedly pressed the nose on the plane, according to a draft of a preliminary report by Indonesian officials looking at last month’s lethal crash .
The investigators focus on whether incorrect data from sensors led the flight system to force the nose downward. The new Boeing 737 MAX 8 killed in the Java Sea on October 29, killing all 189 people aboard.
New York Times reported that information from the Lion Air jet airplane player was included in a briefing for the Indonesian Parliament and reported by Indonesian media. Peter Lemme, an expert in aviation and satellite communications and a former Boeing engineer, wrote an analysis of the data on his blog. The AP could not independently verify the authenticity of the report published online.
Indonesian authorities are expected to issue the report Wednesday, but it is unclear whether they will offer a likely cause of the crash.
MAX aircraft, The latest version of Boeing’s popular 737 jet liner contains an automatic system that slides down the nose if a sensor detects that the nose is so pointed that the plane can enter an aerodynamic stall.
Lemme described “A Deadly Tactic” Where the planet pointed down, the pilots manually opposed the nose higher, only for the sequence to repeat about five seconds later. It happened 26 times, but pilots failed to recognize what happened and follow the known procedure to counter the incorrect activation of the automatic safety system, Lemme told Associated Press.
Lemme said he was also worried that there were no simple checks to see if the sensor information was correct, that the crew of the deadly flight apparently did not warn that similar problems had occurred in previous flights and that Lion Air Jet did not were fixed after these flights.
“Did they fix the plane, we would not have had the accident,” he said. “Every accident is a combination of events, so there is disappointment around here,” he said.
Boeing did not respond immediately to two emails and a phone call requesting comments. The company said last week that it is still safe for the safety of 737 MAX and had given airlines around the world two updates to “emphasize existing procedures for these situations.”
Pilots at American Airlines and Southwest Airlines complained that they had not received any information about the new system at MAX. More than 200 MAX jets have been delivered to airlines around the world.
The survey continues with the help of US regulatory authorities and Boeing. Applicants have not found the planet’s cockpit voice recorder, which would provide more information about the pilot’s actions.
