Remove ENGINE cowlings as necessary to gain access to the magneto ground stud (P-Lead)connection. All airframe component removal and reinstallation should be accomplished inaccordance with the latest revision of the applicable airframe maintenance Remove the P-Lead from the capacitor ground stud. (Reference Figure 1)3. Reinstall the P-Lead retaining nut and washer. Using a properly calibrated and certifiedtorque wrench, torque the retaining nut to 27 If the P-Lead retaining nut can be torqued to 27 inch-pounds without slippage, no furtheraction is required. Remove the retaining nut and reinstall the P-Lead. Torque the retaining nutto 15-17 inch-pounds.

As applicable, make a ENGINE log book entry as to inspection and/or replacement of the partnumber 10-400615 capacitor in accordance with TCM Critical Service Bulletin WARRANTY AND PART DISPOSITION1. Warranty coverage for inspection and replacement of capacitors is as follows:(a) Due to the simplicity of the capacitor inspection, there will be no labor allowance forinspection of service spare capacitors.(b) Labor allowance for capacitor inspection of one or two affected magnetos installed on anengine 1 hour total.

10 Magnetos not included in the serial number range in Table 1 but whichcan be verified through maintenance records to have had a capacitor replacement performedbetween October of 2003 and the effective date of this bulletin may qualify for warrantycoverage for capacitor inspection / replacement.(c) Labor allowance for capacitor replacement on a magneto installed on an ENGINE 1 hour permagneto. This includes capacitor inspection 1.(b).2. Affected capacitors must be returned to TCM as follows:(a) Affected service spare capacitors in inventory These will be returned to TCM by TCMdistribution on a warranty claim. Contact the authorized TCM distributor from which theaffected capacitors were purchased for return instructions and to order replacements.(b) Affected capacitors removed from magnetos - Contact an authorized TCM distributor forwarranty claim application and capacitor return instructions.
