When my son went to school as a mechanic for these jets, only about 25-30% completed the curriculum because of how intense it was, including the multiple FAA board tests required to get a certificate. On top of it, Each airline will train in their own planes. 2 mechanics normally always work together. Never has there been an issue on that airline.
I’m wondering if they loosened the FAA certificate requirements or something and a group of new hires are the cause. Too many problems.
I was a ‘Flight Line Maintenance Mechanic’ for 25 years. I went to an FAA approved school and received my A&P license.
But note an A&P ticket is just a ‘license to learn’. I had to pay my dues and work for a commuter with props, back to school to learn avionics before getting hired by a major airline.
Today, airlines are suffering from staffing shortages at all levels. A person can now get hired right out of A&P school right into a major airline.
