What Arcal76 means to say is, he liked flying the S76 and didn't want to change and that due to critical Engineer shortages within his company, maintenance is struggling to keep up on their 139's.
Other organisations seem to have ironed out any maintenance issues. CHC for instance were doing 300 hour inspections in 4 days on the 139. Arcal76's organisation (when I was there) were doing them in 7-10 days. And it wasn't from a lack of spares. Lack of motivation perhaps, but not lack of spares.
Anyway..... Back to the H160.
Is there anything inside the nose? Because that is a LOT of fasteners to pull off to get inside there. Perhaps production aircraft will have it hinged???
