Yes thank-you, we have asked Cessna support for the feedback on the SEL-57-06 REPORT. We have a 210 G model, manufactured in 1967. The aircraft has always been hangered apart from a few days here and there in a fairly hot climate. We found 2-3 small areas where corrosion had started and have removed the necessary material.
OK, hopefully Cessna will approve your repair if not too deep.
BTW I was recently at Joburg for business and was impressed by the capabilities and workmanship at the SAAT facilities. Do you know them?

How much time has elapsed since you’ve asked? What was their answer?
Hi,
Sorry for the delay in responding. Please see the update.
C210 Serial 21058937 THRU 21058968
uses part 1210702-1
C210 Serial 21058969 THRU 210590199
uses part 1210702-9
C210 Serial 210590200 THRU 21060089
user part 1210702-11
However on the actual Wing Spar in the airplane there is a stamp on the spar that indicates the cast used.
Our C210 falls in the Serial 21058937 THRU 21058968 range and in the official parts guide uses part 1210702-1 however on the cast on the main spar the number 1210702-497 is stamped
We have been advised to ask Textron engineering which cast number will be allowed to be used on the aircraft serial no’s.
The other casts no’s appear stamped like 1210702-498A, 1210702-498B, 1210702-498C will be compatible with the Serial No of other aircraft.
The markings on the spar we have removed from a 210G are identical to those above, other than the hand written engraving is “214” and is erect, rather than the inverted 254 appearing above. I can state for certain that the wing mounting lugs on this spar are not compatible with those of a later 210. The part dash number difference, at least in part, defines these different lug dimensions.
Bear in mind, that the spar is not a casting, but rather a forging, there is a very important difference between the two fabrication methods in terms of strength.
Just to add a layer of confusion, the -497 after the part number is apparently the forging number before final manufacturing, so Cessna could make more than one part number from the forging. So it looks as though the formal Cessna part number is not complete on the part. Refer to the parts catalog for the applicable part number.
I’ve asked the P/N question on the CPA forum with no answer
