This is something we were told by our local maintenance - that the gearbox will need special crating. Also, Airbus said to send just the main unit, i.e. the bottom part of the gearbox. Local maintenance does not have the tools to disassemble the MGB and says it needs to borrow those from Airbus Helicopters. The question is whether it is easier and quicker to send the whole gearbox to Airbus or wait for the local maintenance to acquire the tools, disassemble the MGB, crate the bottom part and send it for overhaul. I have absolutely no idea whether borrowing the tools from Airbus and local work on MGB partial disassembly might be cheaper than let it to be done by Airbus. Any experience in this field???
