🔧✈️ B787 Maintenance Update During a routine check, our team discovered a hydraulic leak at the right-hand nose wheel steering actuator. Further inspection revealed the source — the commutator valve. ✅ We replaced the commutator valve seals, and after testing, no more leaks were observed! 💡 The commutator valve plays a key role in directing hydraulic pressure to the correct nose wheel steering actuator based on wheel position — ensuring smooth and precise steering on the ground.
