Taipei, Aug. 1 (CNA) The black boxes on TransAsia Airways Flight GE222 recorded two unusual sounds immediately before the plane crashed last week, the Aviation Safety Council said Friday.
The first sound was recorded at 7:06:13 p.m. on July 23, two seconds after the pilots requested a go-around, said the council's managing director Wang Hsing-chung at a press briefing on the examination of the aircraft's black boxes.
At that time, the ATR-72 turboprop passenger plane was flying over a wooded area close to the Penghu airport, Wang said.
About three seconds later, the cockpit asked for another go-around, and the second abnormal sound was heard at 7:06:18 p.m., Wang said.
The black boxes -- the flight data recorder and the cockpit voice recorder -- stopped recording at 7:06:19 p.m., he said.
"We can't publicly describe the sounds because it's against the law to do so" during an ongoing investigation, Wang said.
In the area where the first sound was heard, over 20 pieces of flight wreckage were later found, he said.
News reports have said that the aircraft clipped some treetops in a wooded area before crashing into residential buildings near the airport.
TransAsia flight GE 222, which took off from Kaohsiung on the evening of July 23, crashed in the outlying island of Penghu after aborting a landing in inclement weather and attempting a go-around. Forty-eight of the 58 people onboard were killed in the crash.
A preliminary report on the crash will be filed with both the Executive Yuan and the International Civil Aviation Organization by the end of August, according to Wang.
A factual data report will be available by the end of this year and the final report will be completed in 18 months, he said.
