locking (landing gear struts)
- Check rubber mounts in landing gear box for deformation
- Landing gear box for damage
- Tail skid bonding or tail wheel for attachment, function and tyre
pressure
- Wings, fuselage and tail for damage (cracks, buckling, compression)
- Wing's oscillation number
- Control surfaces function and deflections
- Tangential tubes across fuselage for straightness
