It is said that NPAS (or a person in NPAS) were horrified how the Met made their maintenance work. This was an organisation that started up around 1980 and built up expertise focussed on the aircraft in their charge (successively Bell 222, AS355, EC145) to make it work. In the early days there may have been some eyebrows lifted in surprise at the style but in later years less so. As Rigga stated they produced the goods when needed.
It worked but it was not how things were to be done in the new regime.
The operatives were made redundant. The maintenance was transferred to Airbus at Oxford.
Unfortunately, as anyone who is familiar with the maintenance line up at Oxford will testify, there are lines of EC135 and AS350 and 355 in bits but not a sign of any BO105 or BK117 derivatives other than the newly arrived NPAS airframes. In short they may as well have sent Oxford three Mil Mi-8s for all the expertise that they had. They have been behind the curve ever since, even as they got the hang of maintaining the engineer hungry 145s NPAS pulled the PBH to save money.
