One day I arrived at the bay as the tech was about to write NFF. I convinced him that the fault was there as it had occurred on 3 sorties out of 5. Then I realised he was looking at the wrong side of the box. The CC had mixed up N/S and E/W when he did the write up. A quick look at the correct side of the box and a fresh description of how the intermittent fault had occurred and the problem was instantly visible.
Was the same fault entered wrongly three times in the 720 (confusing N/S with E/W) without a question being raised? The norm as I remember it was that the snags were written into the 700 in the ground crew office by the crew Flt. Eng. and normally in the presence of the duty Ch. Tech. in charge of the shift. A recurring snag such as this would/should have raised an eyebrow.
