After ET302,FAA admits MCAS is there and issues notification:mindFly

It took FAA 4 months and a second B-737 accident before admitting the presence of MCAS on board the B-737 Max aircraft. On 11th March 2019 FAA has issued a continued airworthiness notification which includes MCAS design enhancements, Training of flight crew and documentation. All these have to be implemented by April 2019.

For the first time since the Max has been released to service will the pilots be able to access information on the notorious MCAS officially. Isn’t that a big relief?

Read my blog on safety or ethics. A few questions arise:

  1. If this CAN is about MCAS enhancements as a design change, the where is the initial certification of MCAS as it is not listed in the TCDS?
  2. If Boeing recommended a type B training for MCAS to the Brazilian authorities then why has it been downgraded to type A training in this notification? Type A is simple self study from the manuals whereas type B includes checking to ensure understanding of the system.
