China News Agency, Houston, September 17th. Southwest Airlines issued a statement on the 17th, saying that because the actual business capacity of the aircraft is inconsistent with the declared data, the company announced on the night of the 16th that 115 passenger aircraft were temporarily grounded in order to correctly carry the aircraft. Enter the system and restart the program.

As of now, about half of the airliners have resumed service.

　　According to Reuters, the Dallas-based airline stated in a statement that there is a difference of 75 pounds (34 kilograms) between the actual operational capacity of the aircraft and the declared data. This difference exists in a total of 115 Boeing 737-800 aircraft. .

Southwest Airlines said that the grounding decision caused some flights to be delayed or cancelled.

　　Southwest Airlines told Barron's that the decision to ground the flight was made out of "very cautious" considerations.

The company is revising the weighting figures in the system, hoping to minimize the impact on overall operations.

　　In fact, Southwest Airlines has long believed that the aircraft can still fly safely even if there is a 75-pound difference between the actual business capacity and the declared data.

The airline has strongly opposed the temporary suspension of flights on such issues in the past.

　　However, in January of this year, the US Federal Aviation Administration (FAA) stated that in the past two years, Southwest Airlines had more than 20,000 flights involved in weight violations, and the FAA imposed a fine of $3.92 million on the company.

The FAA pointed out that Southwest Airlines used the wrong data on the aircraft's empty weight, center of gravity, and pitch moment. These data will determine the actual passenger capacity, fuel capacity, and cargo capacity of the aircraft.

Its accuracy directly affects flight safety.

　　According to the Wall Street Journal, in February this year, a report issued by the Office of the Inspector General of the US Department of Transportation stated that the FAA did not properly supervise the weight balance and center of gravity of Southwest Airlines aircraft.

According to the report, Southwest Airlines generally misjudged the total weight of checked baggage, and the FAA still allows its aircraft to fly as usual without verifying the actual operational capacity.

　　Southwest Airlines has nearly 750 aircraft, including 34 Boeing 737MAX aircraft, which have been banned from flying after two fatal crashes.

The aircraft temporarily grounded this time does not include 737MAX aircraft.
