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.
