Model Airplanes

In the Philadelphia incident, though, the fan blade may have been thrown forward beyond the containment shield into the engine’s inlet. Fragments of the inlet, a ring in front of the containment shield blades that ensures a smooth airflow into the engine, and the cowling, the metal shell that a plane’s passengers see when they look out the window at an engine, broke off and hit the wing, fuselage, and one cabin window, causing the air in the cabin to rush out.

“The manual has how to handle issues but not that specific combination,” Mr. Soerjanto said. “I don’t know why it was not in the manual. Maybe Boeing never thought that this kind of problem would occur.”

In a statement on Monday, Boeing said: “We are taking every measure to fully understand all aspects of this incident, working closely with the investigating team and all regulatory authorities involved. We are confident in the safety of the 737 MAX. Safety remains our top priority and is a core value for everyone at Boeing.”

Last week, Boeing released a statement acknowledging that Indonesian officials had told the aircraft manufacturer about repeated errant data readings experienced by the plane. Incorrect data readings can trigger the M.C.A.S. system to force the plane into a nosedive, even if the plane is not on autopilot.

Stalls are one of the most common causes of airplanes crashes. But if pilots did not know exactly what system was in place, or that the data being fed into the system was wrong, their reactions could be fatally muddled, aviation experts said.

Pilots should follow Boeing’s manual when confronted with this anomalous situation, the company initially wrote in its advisory last week.

But Mr. Soerjanto’s deputy, Haryo Satmiko, said in an interview with the New York Times last Wednesday that Boeing’s manual was “incomplete” when it came to advising pilots on how to handle a situation in which false data is fed into the automatic anti-stall system to correct for an ascent that was not happening.

Jeju Air, a low-cost carrier (LCC) operated by Korea’s Aekyung Group, will introduce up to 50 new B737 MAX aircraft, Boeing’s latest model.

The budget carrier said in a public disclosure on Nov. 20 that it has placed a firm order for 40 B737 MAX 8 aircraft plus 10 options.

The acquisition cost of the 40 aircraft is about $4.4 billion (5 trillion won). The aircraft will be delivered between 2022 and 2026.

Jeju Air explained that the deal is part of its strategy to build a foundation for sustainable growth. It said the new aircraft will provide major savings in fuel and maintenance costs compared with its existing fleet of B737-800NGs.

The carrier said the new aircraft will also allow it to open up new routes to Singapore and Indonesia as its maximum flight range is 6,500 kilometers, more than 1,000 kilometers further than that of the B737-800NG.

As the fuel efficiency of the new model is 14 percent higher than the B737-800NG, it is expected to reduce the cost of aviation oil.

Jeju Air said some of its orders could be upsized to the larger B737 MAX 10 aircraft currently under development. The B737 MAX 10 can accommodate up to 230 passengers, while the B737 MAX 8 has 189 seats.

Jeju Air also announced that Boeing has promised to share responsibility for the fleet conversion and provide support for engine maintenance and parts supplies.

Jeju Air`s large-scale investment is based on its
