What parts and service manuals should I have for my plane, to help assure good service and correct parts? (Search strings: repair manual, shop manual, CMM, IPC, parts book, parts manual)
The Maintenance Manual for the 19/23/24 is part number 169-590015G, Rev. G5. It is currently priced at $60, new from Raytheon Aircraft Publications. There is one revision package currently available, PN 169-590015G TR 2-1, dated 4/4/97, priced at $20. If you find a used manual (at an airshow or on eBay), it may incorporate the revision already. Please visit the Links section of BAC to visit the Raytheon Aircraft Publications page that shows all the documents available for the 19/23/24 series airframes.
The Maintenance Manual for the Model 76 Duchess is part number 105-590000-7. It is currently priced at $121, new from Raytheon Aircraft Publications. It does not look like Beech has integrated any of the revisions in the currently-sold Maintenance Manual. There is a long list of revision packages currently available; please visit the Links section of BAC to visit the Raytheon Aircraft Publications page that shows all the documents available for the Duchess. If you find a used manual (at an airshow or on eBay), it may incorporate some or all of the revisions already.
The Maintenance Manual for the Model 77 Skipper is part number 108-590000-7 Rev. A4. It is currently priced at $92, new from Raytheon Aircraft Publications. There is one revision package; PN 108-590000-7A4. It is no longer available from RAP, as it has been incorporated in the current printing of the MM. If you find a used manual (at an airshow or on eBay), it may incorporate some or all of the revisions already. Please visit the Links section of BAC to visit the Raytheon Aircraft Publications page that shows all the documents available for the Duchess.
The parts manual for the earlier (pre-1978) 19/23/24 is PN 169-590012J, Rev J2. You want to watch for it on eBay or something; they cost $220 from Raytheon Aircraft Publications. When you find one, make darn sure that it has the J2 revision applied to it (it should say so in the front of the manual, on a revision insert page, or should have the J2 following the part number). The J2 revision itself is no longer available standalone, so if you get a parts book without it, you’re screwed.
This will cover you as long as you have a 19/23/24 airframe with a Model 19 MB865 or lower; Model 23 M1979 or lower; Model 24R MC536 and lower; and all Supers (MA386 and lower). In other words (for example), if you find and buy a 1978 model or later B19/C23/C24R, you will also need parts manual 169-590026E, with revision E1. Same caveat applies to revision E1; no longer available separately. List price on this parts book from RAP is “only” $152, in theory because it doesn’t have anything in it for the early planes.
The reality I have found is that you have to have both parts books if you have a later model. There are omissions in the later book that you can find in the earlier book. To a lesser extent, the converse is also true. The later book sometimes contains numbers for common parts that have been superceded from the numbers in the earlier book. That’s less of a problem, since I can always contact Beech Tech Support for a superceding number, if I have an original number. It’s much harder to get a valid answer if I have no number at all.
The Model 76 Duchess parts manual is PN 105-590000-9C, Rev. C4, for $152. If you find a used one, make sure it has Revision C4 applied; PN 105-590000-9C4, as this publication is no longer available separately. In addition to its use on the Duchess, I have successfully found superceding numbers in the Duchess book that are not in the two 19/23/24 books, for the many common parts.
The Model 77 Skipper parts manual is PN 108-590000-9B, Rev. B1, for $92. If you find a used one, make sure it has Revision B1 applied; PN 105-590000-9B1, as this publication is no longer available separately.
There will be a parts manual and an overhaul manual for your engine. If Lycoming still sells these, they don’t have them on their website. I have found them for sale in places like Trade-A-Plane, parts sellers, and on eBay. The overhaul manual is interesting, but probably not of major value to you. It is of no value for an actual overhaul unless you also have all the Service Instructions/Service Letters/Service Bulletins that legally must also be followed during the overhaul. You do need the parts book, in order to evaluate and identify available parts for your engine. The parts book will cover some relatively narrow range of engines that are very similar to yours, as well as covering yours. When you locate one, try to make sure it is an original Lycoming book (not a reprint by someone else), and has the genuine Lycoming binder (they are much more durable). In my case, the parts book for my Sierra is PC-406-1. I’ve had it for so long that I can’t remember where I got it, but I bought it new at the time. Probably bought it from a display at Sun-N-Fun or something.
