ation and safety officials Daniel Elwell, Robert

US senators sharply questioned regulatory officials on Wedne

sday about the Federal Aviation Administration’s reliance on Boeing Co’s engineers to cert

ify the safety of the company’s new 737 Max 8 aircraft, which was involved in two fatal crashes in the past five months.

A self-certification procedure called Organization Designation Authorization came under scr

utiny at a hearing of the Senate Commerce Committee’s aviation subcommittee in Washington. Testifying wer

e Daniel Elwell, acting FAA administrator; Robert Sumwalt, chairman of the National Transportation Saf

ety Board; and Calvin Scovel III, Transportation Department inspector general.

For decades, the FAA has delegated some authority for certifying new aircraft to the manufacturers, reducing government costs.

After the crashes of Lion Air in Indonesia in October and Ethiop

ian Airlines this month, which killed a total of 346 passengers and crew members, critics have ci

ted the self-certification process as evidence of an overly cozy relationship between the FAA and the industry.
