Is it a two tow-hook system?

Yes



Many G-103's removed the CG hook and replaced it with a dummy block. Was the re-installation proper?

I can't determine that from the maintenance log but it's worth checking.



Look for an obstruction resulting in the nose hook reaching full open and not leaving CG hook sufficient movement to open.

That was my first thought too but I've been lectured that the Twin Astir works differently.

Check by removing CG cable (at hook), then actuating release system. Look for improper CG hook, improper installation, not enough cable movement at CG hook.


Hope this helps,

It helps a lot JJ
