Facing Disturbance, Lion Air Pilot Strikes Up The Plane Before Fall

Black box of Lion Air JT 610 aircraft

Flight data in the Lion Air JT610 black box, which crashed on October 29, showed the pilot's efforts to raise the nose of the plane that was always down. This disclosure is in line with the report of one of the media calling for an error in the control system on the Boeing 737Max 8.

In a preliminary report on the Flight Data Recorder (FDR) investigation in a section of the 

Lion Air JT610 black box, Wednesday (11/28), the Transportai National Safety Commission (NTSC) said the pilot had a control problem on a flight from Jakarta to Pangkal Pinang.

When the pilot raises the aircraft flap, the system automatically lowers the nose or nose down. Black box data shows, the pilot immediately raises the nose or nose up.

But what happened then, the plane's nose dropped back again, then raised again by the pilot. This condition occurred repeatedly until the plane crashed in the sea 13 minutes after taking off from Soekarno-Hatta International Airport, Cengkareng.

A total of 189 crew and passengers were killed in this event."The movement of the nose up and down takes place again until the end of the flight recording," said the Head of the Sub-Committee of the Flight Committee of the NTSC Nurcahyo Utomo in his statement.

In that condition, said Nurcahyo, the pilot reported to the watchtower that the plane's height could not be maintained. The pilot then asked the watchtower to secure the airspace below and on the plane.

"The pilot asked the controller to close the height of 3,000 above and below. This is to avoid any collisions in the air," Nurcahyo said.

According to Nurcahyo also, this condition occurred due to some damage that occurred in the newly purchased aircraft in August. This damage was found on a previous flight, from Denpasar to Jakarta.

"In this event there are multiple malfunctions," Nurcahyo said again.This black box inspection report is in accordance with previous allegations that there was damage to the flight control system of the Boeing 737 Max 8. This damage and guidance on how the pilots handled it were notified by Boeing after the Lion Air incident occurred, killing 189 crew and passengers.

Sources of investigators previously told the Wall Street Journal (WSJ) last month said that if Boeing told it in advance it could be a Lion Air incident that could be avoided. Because this system did not exist in the previous version 737 so it was not familiar among pilots.
