TROUBLESHOOT THIS SYSTEMDefine the reported symptom, confirm aircraft and configuration applicability, then follow current approved fault-isolation and maintenance data.
Why it exists
Direct hot exhaust safely and provide reverse-thrust capability within approved operating logic when fitted.
What belongs here
- Exhaust ducts and nozzles
- Tailpipe or mixer structures
- Thrust-reverser translating sleeves or blocker doors
- Actuators and synchronization
- Locks and position sensors
- Control valves or electrical drive
- Thermal protection
What users may see
Reverser status, deploy or unlock indications, position disagreement and system fault messages may be displayed.
What technicians commonly evaluate
Hot-section damage, exhaust leaks, thermal distress, actuator and synchronization condition, lock integrity, sensor adjustment, hydraulic or electrical isolation and inadvertent-deployment protection are central concerns.
