There are a number of factual inaccuracies in the AAIB Special Bulletin in the last paragraph of the Engineering Investigation section.
1. Following the flight, the commander did not verbally (or in any other way) request that this be addressed. He merely reported his observations verbally and in the flight test report to the engineering rep for engineering to decide if rectification should be made.
2. He elected not to enter it in the tech log because as it was within limits it was not a defect. This is standard procedure. He did however record it as an observation on the Flight Test Schedule.
3. There was a formal written record. The commander gave the original 28 page flight test report, which contained the shakedown manual reversion observations, to the engineering rep.
I expect these errors will be corrected in the final report.
