Other than engineering trouble, flawed design, worrisome prolems are emerging from production line.
The Boeing KC-46 Pegasus, new choosen USAF aerial refueling and strategic transport aircraft to replace old KC-135 Stratotankers, was grounded a first time at the end of february, due to tools and debris left into airplanes, as reported by https://www.seattletimes.com/business/boeing-aerospace/boeing-tanker-jets-grounded-due-to-tools-and-debris-left-during-manufacturing/. Then this happened again a month later, as reported by AirForceTimes latest April 2.
In the mean time, after Ethiopian 737 accident, USAF decided to rewiev training as KC-46 use a similar MCAS to help stability, this review is focused in emergency procedure than as KC-46 MCAS is different from 737 Max, as it uses two sensor and inertial gyroscope for AOA and it's disengaged if pilot make stick input. All this is happening after a two year delay of delivery that are pushing USAF TRANSCOM to defer KC-135 retirement.
Now same problems are happening in Boeing South Carolina, the second factory where 787 Dreamliner are assembled, as reported by New York Times, and to worsen, appear that reports from employeers and quality control were ignored and have received pressure not to report violation.
The 787 Dreamliner was the first airliner with an airframe primarily built on composite materials. It had to be delivered in 2008 but this was delayed till 2011 then, entred in service, it suffered from various problems, fuel leakage, problematic lithium-ion battery design that grounded 787 for four month in 2013, wiring damage, engines stops due to ice shedding in General Electric GEnx fan
