Service Letter No. 249 

Interim Alternative to Address the Discontinuation of Teledyne Dual Magnetos


October 6, 2010

Engines Affected

To all Lycoming Engine Owners, Operators, and Field Service Personnel 

In the wake of Teledyne Continental Motors’ (TCM’s) announcement that they will no longer produce or support dual magnetos, this Service  Letter  introduces Lycoming  Engines’ plan to use  an alternative  replacement dual magneto that will be  used  on Lycoming  engines once our current supply of TCM dual  magnetos has been depleted.
