Momentum grows in Congress for more FAA oversight of Boeing

Pressure is growing in Congress for at least modest changes in how federal regulators approve new passenger planes after two deadly crashes involving the Boeing 737 Max.

On Tuesday, two key senators on transportation issues proposed several changes that would increase Federal Aviation Administration's direct role in the aircraft-certification process.

Their legislation would not end a decades-old practice in which the FAA relies on aircraft manufacturers' own employees to certify the safety of systems on their planes. But it would require the FAA to select the people who do the safety work instead of letting the manufacturers pick them.

Supporters of the FAA’s reliance on employees of aircraft makers point to the safety record of U.S. airlines – no fatal crashes since 2009 – as proof that the policy produces safe planes. Critics say, however, that FAA approved the Boeing Max without fully understanding an anti-stall system that was later implicated in the crashes.

The new bill by the Republican chairman of the Senate Commerce Committee, Roger Wicker of Mississippi, and the panel’s top Democrat, Maria Cantwell of Washington, would make other changes, too. It would require FAA to accept recommendations by federal safety investigators around safety standards for pilot training on modern, highly automated planes. Ordinary pilots for U.S. and international airlines would perform test flights of new planes, rather than leaving the work to highly specialized test pilots.

The measure is stronger than a bill that Wicker introduced two weeks ago and which was criticized by families of some of the 346 people who died in the Max crashes. House Democrats are working on their own proposal to overhaul FAA certification of passenger planes.

The FAA declined to comment. FAA Administrator Stephen Dickson is expected to be...
