Introduction
Foreword BRP-Powertrain provides “Instructions for Continued Airworthi-
ness”, which are based on the design, the tests and certification
of the engine and its components. 
These instructions apply only to engines and components sup-
plied by BRP-Powertrain. 
This Operators Manual contains important information about safe
operation of the engine, together with descriptions of the system
and its layout, technical data, operating media and the operational
limits of the engine.
The specified data apply only to the engine and not to specific ap-
plications in particular aircraft. The aircraft manufacturer’s Opera-
tors Manual is therefore definitive in terms of the operation of the
engine, as it contains all of the aircraft-specific instructions.
Chapter structure The structure of the Manual follows whenever it is applicable the
structure of the „GAMA Specification #1 for Pilot’s Operating
Handbook“. The Operators Manual is subdivided into following
chapters:
