TransAsia Pilots Couldn’t find Runway before deadly Crash: accident report



Pilots of a fatal July 23 TransAsia airlines Corp. flight couldn’t find the runway seconds before their aircraft crashed on Taiwan’s outlying Penghu islands, killing forty eight human beings, in step with a currently launched coincidence record.
“have you ever seen the runway?” the captain of flight GE222 requested his first officer in Mandarin as their plane approached Magong Airport. “No,” the primary officer answered honestly after 9 seconds. The cockpit voice recording ended 12 seconds later, a transcript of the tape indicates.
Ten people survived while the home flight from Taiwan’s southern Kaohsiung Airport hit houses in Penghu’s Xixi Village close to the runway. The file is a authentic account and doesn’t draw any conclusion or lay blame for the crash, Aviation protection Council spokeswoman Sherry Liu said in an interview.
A draft assessment is anticipated to be completed in June with the final report to be posted in October, the council said in a press assertion.
the 2 pilots of the ATR 72-500 twin-engine faster-propeller plane knew that climate situations fell underneath minimum necessities required to land at Magong when they took off from Kaohsiung at five:45 p.m. on July 23, the council stated. The same pilots had flown from Magong to Kaohsiung earlier in the day, it said.
The home flight commonly takes 35 minutes, in keeping with schedules published at the Kaohsiung airport website. storm Matmo surpassed Taiwan earlier that day and had reached coastal China by way of early afternoon.
Thunderstorms
approximately 26 mins after takeoff, flight GE222 become installed a maintaining pattern for 34 mins in the course of which era air site visitors control suggested wind conditions that would offer a headwind for plane touchdown at south-facing Runway 20, in keeping with these days’s declaration. aircraft commonly takeoff and land into a headwind because it offers more carry at slower speeds.
At 6:21 p.m., while GE222 changed into flying circles inside the skies among Penghu and mainland Taiwan, aircraft have been suggested that thunderstorms around Magong could in all likelihood maintain for any other hour. The thunderstorm caution was repeated 20 minutes later.
at the same time as wind situations pointed to Runway 20, the pilots two times requested permission to land at the opposing north-facing Runway 02, which could deliver them a tailwind. Runway 02 has a sophisticated instrument touchdown machine, or ILS, which assists pilots to fly the precise direction, altitude and go with the flow slope. Their requests weren’t accredited by using Taiwan’s military, which also operates at the airport.
ignored method factor
At 7:03 p.m., one hour and forty eight mins after takeoff and with the pilots set up on their final method path, GE222 was given permission to land at Runway 20 which has more simple navigation structures than Runway 02. That clearance was given six minutes after a comparable plane operated through UNI Air landed correctly on the same Runway 20, the report shows. The UNI Air flight had additionally requested Runway 02 and didn’t get approval.
At 7:05 and fifty four seconds, two minutes after getting touchdown clearance, GE222 exceeded under 2 hundred feet and reached a vital second referred to as neglected technique point, at which pilots are required to stop the landing and execute a go around if they are able to’t see a prescribed visible reference, commonly the runway.
Unseen Runway
four seconds later Captain Lee Yi-lian, with nearly 23,000 hours of flight time, requested his fateful query.
inside the seconds it took for the aircraft to climb, financial institution sharply to the left and then factor nostril down, first officer Chiang Kuan-hsing replied within the negative.
“No,” Captain Lee echoed.
“No, sir,” his first officer repeated.
4 seconds later flight GE222, with 58 people on board, had descended to seventy two ft, slightly above the height of close by trees.
“move round,” they each known as, boosting the engines’ throttle just seconds earlier than the cockpit voice recorder captured an unidentified sound. Flight facts indicates an engine had slowed and the pitot tube, which sits at the outdoor of the plane and is used to measure airspeed, had been broken.
“pass round, pass around,” the primary officer radioed to the Magong manage tower in English. “Roger,” came the respond.
