Wing Spar AD Inspection / Pro-Vision Scope

[Robert Szego]

Offline question from a member:

I received the scope yesterday-anxious to use it. Do you have info on how many and where the inspection plates are required to be placed when using this device?

Also you said in an e-mail you had confidence in the wood spars and would fly over water I think you said---does your confidence include aerobatics?

Dear Bruce:

There is no prescribed position for inspection holes; our B-C Contact! articles were only recommendations based on "mirror/light" type inspections. Since the position of the ribs are obvious, just observe how many bays you can reach with the PV-300, then only cut more holes where required to reach every bay.

I have flown 100+ nm overwater legs in the Bahamas several times; also do minor aerobatics to about 3G (my preference, not the airplane's) with total confidence in the wings. BTW, I have been doing good wing spar inspections for 12 years before this ridiculous AD. You can see this recommended in the very earliest issues of B-C Contact!

Pro-Vision Scope? Any details? We are actively looking for a similar device for spar inspection of an aircraft with not so many holes. Mine has enough holes for bend-a-light, but a good fiber-optic system would do a better job.

Dear Bob:

An information sheet on the scope is being sent with your renewal today. Look it over and let me know if you have any more questions.

I just rented a pro-vision scope from Wicks Aircraft Supply, $30 per week.

They have the long one and the short.
