New 737 MAX software issue may cause the aircraft to stay on the ground longer

Seattle, Washington - A new 737 MAX software problem was discovered by Boeing engineers as the aircraft's return date to the commercial service remains unclear.

Aviation regulators around the world have grounded the 737 MAXs after two fatal crashes that the aircraft involved in Ethiopia and Indonesia, which killed 346 people.

The stall prevention system of the aircraft, which is known as MCAS (Maneuvering Characteristics Augmentation System), was pointed out as the cause of both crashes.

On Jan. 13, Boeing said that it had notified the US Federal Aviation Administration (FAA) about the new software issue related to the 737 MAX jets.

The software issue concerns a unit monitoring whether the key flight control systems of the aircraft are working properly or not. One of the monitors was not being initiated correctly, officials said.

The monitor check is prompted by a software command to determine if maintenance is required.

We are making the necessary updates and working with the FAA on submission of this change, and keeping our customers and suppliers informed,

Boeing said in a statement.

In the internal company documents released by US lawmakers, it had been revealed that Boeing employees said the aircraft was designed by clowns and supervised by monkeys.

Boeing is preparing to suspend production of the 737 MAXs this month until the aircraft is allowed to fly again.
