Summary
On December 15, 1989, KLM KLM Royal Dutch Airlines 867 flights were regular services to go to the New Tokyo International Airport (is renamed to the Narita International Airport in 2004) from Amsterdam Amsterdam Schiphol Airport. That the body is within six months after this body is spent in Boeing 747-406M; was a construction machine [1]. 867 flights splashed in the thick cloud of the volcanic ashes from the re-doubt mountain which erupted the day before.
The output of four engines of the body began to decrease during a flight in a cloud, and I left a backup electric power system about 10-15 seconds later, and the engine stopped it. Because the generator of the engine stopped, it became the blackout state for an instant, but an instrument and the hydraulic system worked by a backup power supply, and the operation was possible.
The captain carried out the reboot of the engine many times, but the engine did not reboot, and the body descended.
The plane which carried a turbofan does not incorporate a cell motor starting an engine and usually starts engines using the power supply of the airport basically. Therefore it is necessary to cast a large quantity of and high-speed air as I reach the number of revolutions that a fan can fire when I reboot an engine during a flight. Therefore, what let you let a body make nose dive and breathe in a large quantity of and high-speed air, and continued the ignition, movement to make nose dive again after having caused it when I did not reboot until an engine rebooted was basic [2] and both KLM KLM Royal Dutch Airlines 867 flights and the engine shutdown accident tried a multiple swoop and succeeded in engine reboot, and they made an emergency landing, and all the crew passengers returned safely [2].
Communications records
The next communication was carried out between Anchorage center which controlled a flight area and KLM KLM Royal Dutch Airlines 867 flights.
It is arrival, nose direction 140 in pilot - KLM867, FL250. The Anchorage center - consent. Does smoke look good now? Ash looks like pilot - ええ, cloudy sky. It is slightly browner than a normal cloud. Pilot - we must leave here. The cockpit is smoky. Anchorage center - KLM867 is heavy, and please leave it by the consent, your discretion. I rise to pilot - FL390, and there are us in black clouds. Course 130. Anchorage center - KLM867 which the combustion of all engines stops in pilot - KLM867, and is dropping is heavy, and is it Anchorage? Under pilot - KLM867, a present descent. We fall! I want you to do pilot - KLM867, help. Give me a radar vector!
Engine restart
After having descended, I curl 14,000 feet or more·Fan·Dell·The L strike captain and the crew succeeded in the reboot of the engine at last and were able to land an airplane safely. The repair of the inoperative engine caused the big damage in ash, but neither an injured person nor the dead person appeared. [3] [4]
As of 2013, the plane still does it during service in KLM [5]. It was the painting of KLM Asia at first, but was repainted coloring of the KLM after conserving it in 2012, and having checked it. 867 flights become the flight number to Osaka (Kansai Airport) from Amsterdam as of 2016.
