Question - Describe The Investigation And Remedial Action Required If The Engine Turns On Air But Fails To Fire On Fuel ?
Answer -
If the engine fails to fire on fuel the following points would be investigated, and remedial action taken.
- Check for any shut-downs still active. The shut down panel would be examined, and if a trip is active the cause would be investigated and system made operational. Following this the trip reset button would be pressed.
- Low fuel pressure at the engine manifold. The fuel system would be investigated, and all valves checked to be opened, and all booster and supply pumps checked for running.
- Sticking fuel linkage. The action of the fuel linkage would be checked during the start sequence. The fuel linkage should admit a “starting level” of fuel after the engine start sequence has been completed. The physical movement of the fuel linkage would be checked, and any mechanical friction reduced by lubrication.
