GLJA Posted March 2, 2020 Report Share Posted March 2, 2020 I just saw this on the COPA website, and thought I’d post here. Thankfully, the IO-360A1A isn’t listed. But the 0-360A1A is, which I believe is a C model engine. Any thoughts? https://www.federalregister.gov/documents/2020/01/29/2020-01414/airworthiness-directives-superior-air-parts-inc-sap-engines-and-lycoming-engines-reciprocating Quote Link to comment Share on other sites More sharing options...
luv737s Posted March 2, 2020 Report Share Posted March 2, 2020 Addresses SAP crankshafts only not all crankshafts. Don't know which engines are affected. Quote Link to comment Share on other sites More sharing options...
Guest Posted March 2, 2020 Report Share Posted March 2, 2020 It only affects engines which have a Superior Airparts crankshaft manufactured during the time period. Our local flight school had one of the first ones to break in a 172. Clarence Quote Link to comment Share on other sites More sharing options...

My 1970 C has a -A1D. Quote Link to comment Share on other sites More sharing options...

Greg Ellis Posted March 2, 2020 Report Share Posted March 2, 2020 Apparently it does apply to the -A1D so a check of the serial number will be in order. This is from the FAA AD: (2) With SAP crankshaft assembly, P/N SL36500-A31, installed: (i) SAP Model IO-360-series and O-360-series reciprocating engines. (ii) Lycoming Model AEIO-360-H1A, IO-360-B1A, IO-360-B1B, IO-360-B1D, IO-360-B1E, IO-360-B1F, IO-360-M1A, O-360, O-360-A1A, O-360-A1C, O-360-A1D, O-360-A2A, O-360-C1A, O-360-C1G, O-360-C1C, O-360-C1E, and O-360-C1F reciprocating engines.

Andy95W Posted March 2, 2020 Report Share Posted March 2, 2020 (edited) This looks like it only applies to a total of 253 crankshafts, produced by Superior Air Parts, as aftermarket parts for Lycoming engines and as original parts for Superior's own line of engines (only applicable for experimentals). All anyone has to do is check your engine overhaul and see if you have a Superior crankshaft. You probably don't. IF you happen to have a Superior crankshaft, check it's serial number against the list supplied in the AD. If a serial number isn't listed, contact your overhauler. Again, this doesn't really apply to very many engines. I arrived at 253 crankshafts by simply looking at the affected serial numbers and adding them up. Someone can please check my math: Superior Air Parts, Inc. (SAP) crankshaft assembly, part number (P/N) SL36500-A20 or P/N SL36500-A31, with serial numbers 82976-01; 82976-02; SP12-0003 through SP12-0089, inclusive; SP13-0034 through SP13-0150, inclusive; or SP14-0151 through SP14-0202, inclusive; installed.

Mine was overhauled by Signature a couple or three years before I bought her in '07. Sure would simplify digging through the logbook!
