Cigarette lighters in 100 series Cessnas and an AD(?)
I vaguely recall someone mentioning to me once that there was an AD regarding cigarette lighters in Cessna 172s of some vintage. But I've searched around trying to find this (including at the FAA web site), and have failed. Anyone have pointers (or is this perhaps an "urban myth")? Thanks... Andrew |

Andrew It is an AD that applies to the Piper PA22 I own. The cigar lighter in all three 100 series Cessnas I have owned were disconnected per a Cessna Service Bulletin (never became an AD AFIK) |

The avionics master and split bus were also installed and logged as a minor mod before I got the airplane. The Cigar Lighter was also repowered via an added breaker in the Pacer, and via an in- line fuse in the Cessna, also logged as a minor mod with AP signoff. |

A resistor in the cigar lighter system was consistently burning up. The original problem was that the lighter socket went straight to the bus without any circuit protection whatever, and a short in that system caused electrical fires. I think the resistor was in the 177 and some other later Cessnas to drop the 24-volt supply to 12 volts for the standard cigar lighter, and that resistor, carrying so much current, got pretty hot. Any wires that a later technician tied up against it would get burned, too. We have 1-amp fuses in the lighter socket line so that accessories such as GPS can be plugged into it. We don't allow smoking in our airplanes. Smoking ruins gyros in short order, too. Dan |

We went with a 10 amp fuse. 1 amp is not enough current. You must be using the lighter itself. An amp or so is enough for most electronic doodads. Many of them draw only a few milliamps. Dan |
