Jet Airways, SpiceJet asked to check the Boeing 737 Max Jets after Indonesia Lion Air Crash

Incomparable reliability ensures that 737 Max flights depart in time with fewer delays, says Boeing

New Delhi:

The DGCA airline regulatory authority has told Jet Airways and SpiceJet to control all Boeing 737 Max aircraft for an issue that could lead to "significant altitude loss" a week after a brand-new plane of the same model sinking into the sea, off in Indonesia.

The Federal Aviation Administration and Boeing have given advice on what they could do to avoid similar incidents involving the Boeing 737 Max after the Indonesian air crash, which killed all 189.

Jet Airways and SpiceJet are the only airlines in India that travel with the Boeing 737 Max.

"Both documents (FAA and Boeing) face a wrong high-angle intrusion sensor and corrective action for itself, as it has recurrent horizontal stabilization capabilities," said a senior Civil Aviation General, who asked not to be named.

The angle of impact is a technical term referring to the angle between the incoming air or relative wind and a reference line in the airplane or wing, according to Boeing. Sometimes the reference line is a line connecting the tip and the rear edge to a midpoint in the wing.

The DGCA official said that if the term was not met, it could cause the crew to have difficulty checking the plane. The situation may even lead to "excessive nose-bottom stopping, significant altitude loss and possible landing (airplane crash)," said the official.

Based on the initial Lion Air crash survey, the FAA issued Wednesday the extraordinary directive on airworthiness. Boeing also published a news release on Tuesday.

The DGCA official stated that the changes to the flight manual should be made within three days of receiving the US Airworthiness Directive. the manual shall include procedures to be followed by the flight crew.

"The DGCA has ensured that all Indian players are aware of the FAA AD and have taken appropriate corrective action," he added.

Comments from Jet Airways and SpiceJet were expected.

Indonesian researchers said on Wednesday that the plane had organ damage on four flights, including a trip where both the AOA and the air velocity sensor were affected.

Soerjanto Tjahjono, head of the Indonesian National Transportation Safety Committee, told reporters that after a flight from Bali to Jakarta – the last flight before the crash – the left and right AOA sensors were found to disagree by 20 degrees.
