Boeing’s bid to leave wiring bundles in place on the grounded 737 MAX has not won the support of U.S. aviation regulators, a person briefed on the matter said.
In February, Boeing told the Federal Aviation Administration (FAA) it does not believe it must separate or shift wiring bundles on its grounded 737 MAX jet that governors have warned could short circuit with catastrophic consequences.
The source stated the FAA told Boeing Friday that it didn’t agree with the plane manufacturer’s argument that the aircraft’ wiring bundles meet safety standards and now it’s up to Boeing to decide how to go ahead.
The FAA stated Sunday it “continues to engage with Boeing as the planemaker works to deal with a recently found wiring problem with the 737 MAX. The manufacturer should demonstrate compliance with all certification standards.”
Boeing stated Sunday it was in ongoing talks with the FAA over the problem. Boeing may choose to make a new offer or shift the bundles or try to convince the FAA to reconsider its position; however, a U.S. delegate stated it was “unlikely” the FAA would review.
Boeing and the FAA first said in early January they had been evaluating a wiring problem that could potentially trigger a short circuit on the 737 MAX jet, and under certain conditions lead to a crash if pilots didn’t react in time.
Boeing’s 737 MAX Jetlines was grounded globally in March 2019 after two accidents in Indonesia and Ethiopia killed 346 people within five months.
