All,
If you do not have the AMOC letter attached to your perminent records allowing you to use Piper SL 782B as compliance data for complying with AD 77-13-21para. A,C (1000 hr gear inspection), then you are in violation because there is no way that your AD was done as 782B is un approved data according to the AD (AD requires use of only SL 782A for compliance, and does not have the clause "or latest revision to series" so no other document is allowed to be used). Shops and A&P/IA's, if you have a copy of the old Piper SL 782A as required to comply with the AD, then YOU are in violation as it is unapproved data and any reference to it is to a non document as SL 782B superseeds and voids all previous documents in the series, and oh yeah is you dont have the AMOC document and you sign off the AD using 782B, then you are also in violation!
The reason I bring this up again is that this has been reported again, that a shop was cited and fined, and several aircraft were grounded due to this situation. The only aircraft that did not have to redo the 1000 gear inspection was one with the AMOC in its records, and the owner knew enough to produce it thus satisfying the FAA inspectors. So for all you out there that don't have this document, here it is!
