Pushed to fit an engine that wasn’t meant to fit the plane
- Pushed to fit an engine that wasn’t meant to fit the plane
- Relied on a questionable patch to keep the plane from stalling
- Cared so little about it that they outsourced it to India and to lowly paid junior engineers
- They didn’t verify it actually worked safely or was integrated properly
- During certification, MCAS was eventually given so much control authority that pilots could not overpower it (trim controls the full horizontal tail, and elevator only a tab on it. At higher speeds, elevator canont overrule the tail)
- A single AOA failure would cause the plane to pitch down to a crash. Using both AOA sensors available in planes, would have been more work and delayed shipment.
- Are 2 sensors even enough? AF447 had 3 pitot tubes so that you can rule out a bad reading with the other 2.
