FOD is an old problem solved years ago. You’d think Boeing would have never allowed it to re-occur.
Excuses, Excuses. Ridiculous. The US Air Force contracts with Boeing and specifications are different than commercial aircraft. Anyone who has worked around aircraft or airports know how seriously FOD or Foreign object debris is to the military. They have squads of service men in a long line that patrol to scour from end to end of the flight deck of aircraft carriers searching for small debris. Same with airports. FOD can ruin a gas turbine engine in a fraction of a second. This isn’t some new problem either.
While an aircraft is being manufactured on the assembly line, it has what is known as “out of position” work- in other words a delay to finish a certain assembly task must be finished in a different position further down the assembly line that it was originally supposed to be completed. It happens all the time. No big deal. That isn’t a good excuse as the Wall Street Journal mentions what was used by Management at Boeing to the FAA inspectors. For example when a wing section (which fuel is stored in) is “Closed out” with the final QC done by a visual inspector- not even a tiny 4-40 sized screw or rivet is allowed inside the tank- let alone larger objects. When at McDonnell Douglas Aircraft there was an entire department whose task was to X-Ray the entire wings and specific structural sections then review all the film to verify that no FOD existed. A critical step.
The question is did Boeing follow the same procedures as were used at DAC? And if not, why not? Too expensive to X-Ray for FOD? Well Boeing is now in trouble- and this fairly simple process you would expect the general public to demand for safety reasons.
Meanwhile the 737 Max fleet is grounded everywhere they were sold. That is a much more difficult issue to fix. Not only the perception that the public has on the product- but on safety and the angle of attack sensors and CG being controlled by software. The question remains was it good idea to put new engines on this redesign modification to compete with Airbus?
