Think you're doing the "right thing" by taxi-ing fast? Read the following (abbreviated) report:

Synopsis
On August 29, 2000, Japan Airlines (JAL) flight JL791, a Boeing 747-200B, Japanese registration JA8161, landed at Shangai PuDong International Airport, Shanghai P.R.C. at 11:50 (Beijing local time) having departed from Narita International Airport, at 09:20. The airplane's righthand wingtip hit the floodlight post at 11:53 at parking lot 208 during taxi-ing to the gate 19 after landing. The righthand wingtip was broken and cut off. No injuries were reported.

The Crew Factors
The pilot who conducted the taxi didn't observe the obstacle around and the marks on ground during his taxi-ing to the gate, while the other crew members also didn't have a good sense of situational awareness.

There is no guidance line from parking lot 208 to gate 19. The crew should stop immediately if there is no guidance line which could have been followed when the aircraft approached the parking lot 208, but he continued his taxi-ing blindly and turned left, which caused the airplane wing tip to hit the floodlight post.


The taxi speed at turning of the airplane at the time of hitting, exceeded the Boeing operation standard for the taxi speed of less than 10 knots. The actual taxi speed at turning of the airplane was 11 knots



Moving right to the end of the report.

The Airport Factor
The airport authority didn't provide the information of the additional guidance line in the appropriate aeronautical information publication or to the air traffic service unit after the marks had been painted on the apron.


Conclusion
The investigative team determined that the aircraft accident was caused by the crew human error.

Safety Recommendation
The pilots of JAL shall enforce their pre-flight preparation. JAL shall enforce the CRM and situational awareness trainess.

The Shanghai PuDong International Airport shall repaint and renumber the taxiway for the convenience of the ATC instruction and crew taxi-ing, box all the parking lot numbers on the apron with black frame for easier identification.

The Shanghai PuDong International Airport shall paint new guidance lines to each parking lot and clean all the former guidance lines leading to parking lots 201 through 211.
The airport authority shall provide the information concerning any instructions of marking changes on the apron to the relevant units.

The Shanghai PuDong International Airport shall remove all the floodlight posts along the parking lots 201 through211.


As you see, the REAL cause of the above accident was lack of/incorrect taxi line markings, and the lights being located too closely to the taxi-way. However, as usual, the crew cop the blame.
