BAE146 structure...I flew it...heard one thing interesting...they couldn't take the paint off and polish it up to an aluminium shine...really tried, then found out from manufacturer that it can't be done...safely.
interesting plane...very soft landings....I mean even an idiot could get a grease job.
and the rest of us , super grease jobs.
I made one, maybe my third landing in the plane that was so smooth we didn't know we were on the ground until the WOW system allowed ground idle in the throttles
