How come this trim problem would only be cropping up now rather than with the early builds?
I believe that the fault is only on the next aircraft for QF (MSN27, 5th delivery for QF). Something obviously went wrong during the construction process and wasn't picked up during the normal systems checks. It was apparently picked up during pre-delivery test flying.
Aircraft from MSN26 on are classified as "Wave 2", in that the production process is more standardised in comparison to the earlier aircraft which had to be partially re-manufactured due to earlier production problems.
