A LH Cargo 772 recently took off with the two main static port lines not connected after maintenance. Clogged, capped or frozen Pitot tubes have caused air plain crashes.
Is there no self testing system commercially available or has been proposed that would detect major leaks, unconnected lines or closed ports to the outside world?
B2 should have carried out a complete test with a test set. If the system was incomplete, it would have showed a massive fail. The stamper should be prosucuted in a legal court if they signed it off. Too many gash people with stamps. Actually both stampers should be done as they stamped and never checked.
