As incomprehensible as it may seem in our 21st century I am aware that there are still a handful of professionals for whom top dollar is not their bottom line.
Moreover, in a large number of mid-to-large size helicopter operating companies the engineering remit is an immensely interesting and diversified field of expertise. Also, and in particular on contracts where aircraft are required to be fitted with specialist equipment, maintenance teams can become involved in complex flight/engineering development processes along with the ongoing support/development of those systems.
Perhaps imperceptible now but .. with the development of increasingly 'modular' maintenance and the growing overlap of flight and maintenance systems I would hazard a guess by suggesting that we may well see less of a 'gap' between operating (pilots) and maintenance (mechanics) in the future.
It is not impossible that someone who has been flying may discover an appeal for working on the ground with the aircraft's technical systems.
