These bean stealers have possibly made the assumption that:
Air-test costs = £
x No. of incidents following engine remove/refit/change = 0 or negligible
Therefore £x expenditure not required.
Slightly flawed. Perhaps they should report to their superiors that the money they are spending on engineers appears to be well placed. And as the aircraft gets older you are likely to encounter more problems, not fewer.
IMHO
