Introduction
BRP-Rotax GmbH & Co KG (hereinafter “BRP-Rotax”) provides “Instructions for Continued Airworthiness”, which are based on the design, tests and certification of the engine and its components. These instructions apply only to engines and components supplied by BRP-Rotax.
Before operating the engine, read this Operators Manual carefully. If any passages of the Manual are not clearly understood or in case of any questions, please contact our ROTAX® Authorized Distributors or their independent Service Centers.
This Operators Manual contains important information about safe operation of the engine together with descriptions of the systems, technical data, operating media and the operational limits of the engine.
The specified information and procedures apply only to the engine and not to specific applications in particular aircraft. The aircraft manufacturers Operators Manual is therefore definitive in terms of the operation of the engine, as it contains all of the aircraft-specific instructions. BRP-Rotax wishes you much pleasure and satisfaction flying your aircraft powered by this ROTAX® aircraft engine.
Orange caution lamp of TCU blinking
- In case of an orange blinking TCU caution lamp. Required pilot action:
- Observe engine speed and manifold pressure
- If engine speed and manifold pressure are outside of the operating limits — reduce speed and boost pressure manually to be within the operating limits
- If the manual adjustment of manifold pressure and speed is not possible anymore the servo motor of the turbo charger waste gate need to be switched OFF
A blinking orange TCU caution lamp has to be recorded by the pilot in corresponding documentation (e.g. engine and/or aircraft logbook). Subsequent maintenance action is required. The specific pilot action also depends on aircraft related installation situation (operational conditions, additional installation provisions, etc.) and can not be determined at the engine manufacturing level and therefore must be established at the aircraft manufacture’s level.
Failure of the voltage supply to the TCU
- At a failure of voltage supply the servo motor will remain in its momentary position.
- Wiring shortcomings in installation, switching of voltage supply etc. may cause a failure of voltage supply. In accordance with the instructions of the aircraft manufacturer the cause for failure of voltage supply needs to be verified. First pilot action would be to make sure that voltage supply is activated. If failure still remains, the power setting needs to be adapted as required.
- Limited flight operation need to be considered as boost pressure control is not possible.
Any exceeding of the max. admissible operating limits must be recorded by the pilot in the logbook, stating the duration, exact time and extent of exceeding.
