Narrative:
An Embraer ERJ-145LI passenger jet suffered substantial damage in a landing accident at Shanghai-Hongqiao Airport (SHA), China.
The aircraft, flight MU2947, departed the left side of runway 18L onto taxiway A2 while landing at Hongqiao International Airport in moderate rain. The 5 crewmembers and 44 passengers were uninjured, and the nose landing gear sustained minor damage.
After this incident, the nosewheel steering manifold assembly and electrohydraulic servo valve (EHSV) were tested by the components’ manufacturers according to their returned component acceptance test protocols, which are the same tests that newly manufactured components would undergo before delivery. After both components passed their respective acceptance tests, they were removed and disassembled; foreign object debris (FOD) was discovered inside the EHSV housing in an area where it could block a hydraulic port, subsequently leading to an uncommanded left nosewheel turn.
