Has anyone had failures of the nose gear? I just acquired a new, never-flow A-6. On the first landing, which was quite gentle on a fairly hard/smooth dirt/sand runway the nose gear collapsed. Post-accident investigation revealed that the plastic housing had split on both sides and the flange was broken on both sides. There was no metal flange reinforcement. I ordered a new nose gear servo and metal flange reinforcement. I guess landing on the mains and keeping weight off the nose gear is going to be de riguer.
On another subject: CG. I ran the Mean Aerodynamic Chord calcs. It looks like placing the CG at 30% back of the leading edge at MAC puts the CG at the leading edge of the fan housing, about 0.4 inches further back than the manual recommends. I'm going with that as a starting point. I think the CG can be placed even further aft. Time will tell.

How old is it? The first ones out, 11 years ago had a poorly (poorer than the current one) designed nose retract and many of us broke them. From memory none have had the metal plate. Also be careful about balance. The book value works and if you go aft it really flies poorly.

This is the new high performance version. Except, the nose gear was low performance.Originally posted by Evan D View PostHow old is it?

Funny you mention being half deaf from being around A-6's. I have a funny story about the A-6 on the USS America. Needless to say they were LOUD!Originally posted by Evan D View PostGroundhog day. You were complaining about this a couple weeks ago. Personally, I have had both the original and newer versions and didn't notice a difference but I'm half deaf from working on real A-6's on the flight deck.
