Trouble.bmp (238134 bytes) This is Lycoming's official troubleshooting guide for their aircraft reciprocating engines.  It is broken down into 21 possible faults (as listed below)   Each general fault is followed by its possible causes, the solution to those causes problem, and then the procedures for implementing that solution.

This is not a fancy publication (nor does it have a fancy price); but rather a step by step sequence of procedures which could save the operator or mechanic significant amounts of time, money, and frustration when attempting to diagnose unknown engine problems.
