Seat cartridges etc
Hmmm. Well assuming the enthusiastic engineers have not buggered, over temped the engines while starting them up and taxiing etc there is the small but expensive issue of replacing the MB cartridges in both seats.... Oh and ensuring there is a parachute in the brown bag and not a collection of rags...Oh and installing the seat properly with the top latch engaged otherwise someone might fall out the plane again while doing loopy loops....
A good aircraft if run by a decent group with sensible engineers.
