The Indonesian Transport Safety Commission (TSA) on Monday reported a malfunction suffered by the Lion Air plane, which crashed into the sea last week.
The Boeing 737 Max 8 crashed into the Sea of Java 12 minutes after taking off from Jakarta, killing 189 people.
According to the first information from the Black Box, the Committee stated that the speedometer had been disabled. "Four flights encountered a speed problem," the official told a news conference.
According to the committee, the speedometer was disabled and repaired during the last three flights before the crash, but the problem reappeared in the last flight.
The same source said: "Whenever the problem appeared, the pilot informed the matter and the technical teams repaired it and the plane returned flights," pointing out that the cause of the problem will be studied and verify the work of reform.
But he did not say whether the problem contributed to the crash, especially as the information in one of the black boxes was still under study to determine the circumstances of the accident.
Transport Minister Bodi Kariya Somadi said, "We are launching a special investigation into the efficiency of the crews and communication with the staff." "It's a precautionary measure because the incident was a lesson that we paid dearly for, "He said.
Lion Air is the largest low-cost airline in Indonesia. Earlier this year, it announced its intention to buy 50 Boeing 737 Max aircraft for $ 6.24 billion.
The company's aircraft have seen several accidents, the most serious of which occurred in 2004 when a plane took off from the runway in Solo (central Java), killing 26 people.
Indonesian relief teams are still searching for wreckage and debris. Only 14 people were identified after DNA analysis.
