Wing Spar Inspection

I was in a bonanza maintenance shop yesterday and he said they got in trouble with the local FSDO for signing off wing spar inspections as an IA. Said he’d been doing it for 20 years and they claim it’s illegal. He said everyone who has a logbook sign off by an IA is not legal to fly. He stated it takes a level II inspection authority for dye penetrant and a Level III for eddy current. What are all of us flying Bonanzas that have required inspections supposed to do? I’ve not seen this posted anywhere. Claims he has discussed this with Bob Ripley.

Model: Bonanza V35A

Neither AD 95-04-03, or the service bulletin incorporated by reference (BSB2360) call out the requirement for a level II inspector. If it is a shop that got in trouble, as you suggest, they must be a repair station that has the level II requirement in their repair station manual.

Other than that, dye-penetrant inspections was A&P 101 when I went to school in the 1970's; would need someone to show me where I may not approve a properly completed test.

ABS technical department is working with Textron in locating a document that gives guidelines on the forward carry through structure dye penetrant inspection as per an AD note on the Baron and Bonanza aircraft.
We will keep the the membership advised on the progress and any additional information we gain.

We have heard this story before in the composite materials industry. The primary NDI technologies used are ultrasonic, laser interferometry and laser thermography. The manufacturers of the equipment and the schools that teach inspection techniques are always pushing for higher and higher levels of operator certification. It keeps adding cost and time to the inspection process.
