Thanks for replying to my question.
We use AS332L for,
1. carrying load from 2 to 3 tons .
2. power line construction, logging, and carrying equipments for construction in mountain area.
3. onshore, in mountain area (up to 7000ft MSL)
4. usually 500 to 700 flight hours per year.
We have 2 super pumas now, and are considering to add next helicopter. I think it’s better to buy same one, but I worry about increasing maintenance cost, especially parts price, availability and lead time. That’s why I was asking what do you use for such purpose.
