Document Type: Book (Informational) Purpose: Informational. Authority: Author Expertise. Series: Light Plane Maintenance Library

Scope: General knowledge book written for General Aviation pilots, owners and mechanics. Written by the Editors of Light Airplane Maintenance magazine.

From the dust jacket: "It can be argued that the aircraft engine's "bottom end" — i.e., the crankcase, crank-shaft, camshaft, accessory section, etc. — is among the least understood parts of a modern light plane. This volume of the Light Plane Maintenance Library attempts to change that. This book is a companion to the first volume of the series, FWF: The Top End. As such, it is intended to broaden the operator's understanding of firewall-forward phenomena other than those involving values, pistons and cylinder barrels. When it comes to firewall-forward components, knowledge is indeed power. Here the editors will give you that knowledge by examining three major areas of concern and consideration for greater engine life and better performance."
