Delta Flight Diverts to Tokyo After Hydraulic Issue in Mid-Flight

A Delta Air Lines flight operating from Shanghai to Detroit made an emergency landing at Tokyo Haneda Airport on November 28, 2019, after experiencing hydraulic issues mid-flight. The aircraft, an Airbus A350-900 registered as N512DN, was approximately 140 nautical miles (259 km) north of Tokyo when the crew decided to divert to the nearest major airport for safety.

The captain declared an emergency, leading to the temporary closure of the runway at Haneda as emergency teams prepared for the aircraft’s arrival. Upon touching down safely on Runway 34R, the plane was met by ground emergency services, ensuring the safety of all passengers and crew onboard.

Delta Flight 388 had departed from Shanghai Pudong International Airport (PVG) at 17:46 local time, with a scheduled duration of about 13 hours. The flight was on track to arrive at Detroit Metropolitan Wayne County Airport (DTW) at 18:05 the same day. However, the hydraulic issue prompted the flight crew to act swiftly, prioritizing the safety of everyone aboard.

Response and Aftermath of the Emergency Landing

Following the aircraft’s landing, the runway remained closed for approximately 30 minutes to facilitate emergency procedures. Once cleared, the aircraft was towed to the gate, where Delta announced that the remainder of the flight was cancelled. A spokesperson for Delta Air Lines confirmed the incident, stating, “On November 28, the crew of Delta flight 388 followed procedures to divert to Tokyo-Haneda after reporting a mechanical issue while en route from Shanghai to Detroit. The aircraft landed safely, and we apologize to our customers for the delay in their travel plans. Nothing is more important than the safety of our customers and crew.”

The A350 remained at Haneda overnight before being repositioned to Seattle-Tacoma International Airport (SEA). It departed from Haneda as flight DL9888 on November 29 at 23:14 and arrived in Seattle at 14:26 local time. A corresponding service was subsequently added to Detroit, arriving at 23:02 on the same day.
