The NTSC and the Head of aviation communications never said that Lion Air, Boeing 737-8 MAX aircraft enrolled PK LQP, was not airworthy, said investigator Nurcahyo Utomo.
The issue of airworthiness is crucial due to concerns over problems with the newest Boeing 737 MAX, which crashed and queries over the airline’s security procedures.
Black box data showed the pilots fought against automated system which chucked a Boeing jetliner’s nose down repeatedly due to a faulty sensor till they eventually lost control. All 189 people aboard the flight between the Indonesian capital of Jakarta and the regional airport died in disaster.
National Transport Safety Commission researchers were reporting this week on data from the aircraft’s black boxes. The report stopped short of putting blame for the collapse – the investigation is continuing.
The researchers says the cockpit voice recorder, that remains missing and being searched for, is required to comprehend what precisely caused the jet to dip in the Java Sea only 11 minutes after takeoff.
Utomo said the plane had experienced technical problems on four of the six flights before it crashed. On its penultimate flight from the Balinese capital of Denpasar to Jakarta, as throughout the final one, pilots struggled to prevent an automatic security feature from forcing the nose of the airplane down due to problems with its sensors. And said that based on maintenance documents, flight engineers had made repairs and run tests as required.
Based on the test results, the airplane was declared airworthy when the plane departed from Jakarta, the aircraft was in airworthy condition. He explained. Another investigator, Ony Suryo Wibowo, said there are procedures to be followed when there are problems with an aircraft.
However, when the scientist has said it is airworthy, then it is rdquo, & airworthy, he explained. Wibowo said the aviator would make the final choice about whether cancel or interrupt the flight, and investigators tried to understand the aviator made his decision.
When the airplane is on the floor, the liability for airworthiness is on the engineer, and once the plane is in the atmosphere, the airworthiness is in the pilot’s hands. He explained. Specialists say Boeing might need to modify its anti aging stall system, perhaps developing an algorithm to disregard sensor readings which appear off base.
The airplane maker has a fantastic deal at stake in defending its plane. More than 200 MAX jets have been sent to airlines around the world. Pilots at Southwest Airlines and American Airlines complained this month they’d not been given all information about the new automated anti-stall safety system on the MAX.
