I am looking to purchase a Ballanca Super Viking and would like to compile a list of known items to look for during the pre-buy inspection. I will have an A&P with me but would like to know what he is looking for. The following is a list of known items:
Horizontal tail attach point - Cracks in down tube
Aileron bracket movement where attached to read spar
Rear spar cracks at flap attach points
Visually inspect for fluid stains in wing structure from every access point. If stains are observed, further investigate with an inspection wire for rot damage.
Visually inspect for compression cracks on spar and ribs from every access point. Compression failures are usually noted by dark colored lines crossing the wood grain.
Visually inspect spar butt for cracks toward attach bolts.
