The company I work for has Ramp One worksheets, Transit worksheets and ETOPS worksheets and with a few exceptions like tyre pressures the Etops and Transit worksheets carried out immediately prior to dept duplicate the whole Ramp one that was done 1 hour previous. Waste of manpower or what? I do feel however that the thought of an in flight turnback of an ETOPS 13hour flight to Peking, due oil loss, can justify
the practice if the company is prepared to pay for it and budget for the manpower.
I would say further that a flight crew walkround properly done is yet another inspection of some items and then the pushback crew do some of the items for the fourth time.
If nothing else a second inspection focuses the attention of somebody doing a job that it
is an important task. You shouldn't have to ram this home so often, but familiarity breeds contempt and it has to be recognised and addressed.
Also there is a destinction between a duplicte inspection and a second inspection.
