A whistleblower has claimed America’s Federal Aviation Administration misled investigators checking whether FAA personnel were fully qualified to sign off Boeing 737 Max training standards.

A letter published by the US Office of the Special Counsel (OSC) claims that the FAA had contradicted itself in statements it made about air safety inspectors’ (ASIs’) qualifications and their competence to sign off crucial Boeing 737 Max training standards and materials.

Potentially, a whistleblower told the OSC – essentially a federal watchdog – 11 out of 17 ASIs working for the FAA’s Seattle-based Air Evaluation Group either did not have the right classroom training or the required on-the-job training to perform their duties correctly.

The allegations will pour fuel on the fire burning under Boeing’s 737 Max and its controversial MCAS software system, which was sneakily included in the new airliner in such a way that it could take control from the pilots in a way which wasn’t obvious to them to avoid a stall.

I think that recertification of the 737 MAX is going to be a lot more difficult than Boeing envisions, because neither the EU nor China are going to take the FAA’s word on this.
