You're playing fast and loose with the facts again - the root cause of the BA038 rollback problem was discovered and proved by the AAIB using a test harness.
The presence of manufacturer representatives on investigating teams is nothing new, and they're usually welcomed because they know the systems and airframe better than anyone else. As yet, no manufacturer has directly interfered with the investigatory process - because the risks of doing so considerably outweigh any potential benefit.
