"data-reactid =" 23 "> WASHINGTON (Reuters) – Boeing Co and the Federal Aviation Administration (FAA) confirmed on Sunday that they are investigating a wiring problem that could cause a short circuit on the grounded 737 MAX.

Boeing spokesman Gordon Johndroe said on Sunday that the U.S. aircraft manufacturer identified this issue as part of this rigorous process, and we are working with the FAA to conduct the analysis. It would be premature to speculate whether this analysis will lead to design changes. "

The New York Times reported that Boeing is checking to see if two bundles of cables are too close together, which can lead to a short circuit and possibly a crash if the pilots do not respond appropriately.

The FAA said in a statement on Sunday that the agency and the company "are analyzing certain results of a recent review of the proposed changes to the Boeing 737 MAX." The agency added that it would "ensure that any security issues identified during this process are resolved."

Boeing is currently working on disconnecting the cable bundles and performing a comprehensive analysis to determine if the electrical failure could occur in a real-world scenario, according to a company official.

Officials said the FAA had instructed Boeing to complete an audit in December. The wiring problem could delay the MAX's return, officials added. Reuters previously reported that the FAA is unlikely to approve the aircraft until February, and may not be approved until March or later.

The FAA described the wiring problem as potentially "catastrophic". It is possible that other protective measures such as shielding, insulation, and circuit breakers could prevent the short circuit, said a company official.

Boeing will cease production of the 737 MAX this month after the top-selling plane killed 346 people in March after two fatal accidents in five months.

Last month, Boeing's board dismissed CEO Dennis Muilenburg after repeatedly failing to contain the consequences of the crashes that tarnished his reputation with airlines and regulators.

The crisis cost Boeing $ 9 billion and injured suppliers and airlines.

Boeing is working to improve relations with the United States and international regulators, which it must win to get the jet back in the air.

US and European regulators are expected to return to Iowa this week to review an audit of the 737 MAX's software documentation, which was not finalized last year. The FAA and the European Union's Aviation Safety Agency will meet in Seattle this week and return to the Rockwell Collins facility in Cedar Rapids, Iowa this weekend for review testing.
