Does anyone know if AC LS86 plugs are suitable for the R-1340? I have a lot of them ex Swiss AF AT-16 stock, but according books they rather go on R-2800. Thanks. |

From FAA TCDS page for the R-1340 Note 6. Approved Spark Plugs for AC brands do not include that number. http://rgl.faa.gov/Regulatory_and_Guida ... L/5E-2.pdf  |

Please also note that some of the plugs listed in the R-1340 TCDS will not fit the T-6 harness. The connector from the harness is a different diameter on those. No need to ask me how I know this... ![]() |

Thanks for the doc Rich. I found on the list AC S86R and AC HSR 86. Meight be "86" is the heat range and I can use LS 86's. The ones I have are equipped with an adapter ring to shorten the thread. Will do some more investigation before installing them. cheers christian |
