Document Type: Operations Handbook and Manual Authority: Manufacturer (authoritative reference)

From the Introduction: “This manual is intended to serve as a ready reference for Eastern Air Lines flight engineers who use the Sperry Engine Analyzer as a troubleshooting tool.

Since more effective use of the Engine Analyzer requires a sound knowledge of the [Pratt & Whitney] R-3350 engine and its ignition system, engine and ignition system information have been compiled along with the various Engine Analyzer subjects to make this manual a complete reference for Engine Analyzer operators.

The information available in this manual is for use in detecting and correcting or minimizing the effect of engine malfunctions and is not intended to deviate from any existing company policies or procedures.”

Scope: Contents include sections on: Principles of Operations, Troubleshooting the Engine Analyzer, Operating the Engine Analyzer, Engine Data, Low Tension Ignition, Pattern Interpretations, and Engine Troubleshooting Techniques.
