Egypt: Recorder's memory unit found despite damage to cockpit voice recorder
EgyptAir Flight 804 crashed in Mediterranean in May with 66 people aboard
The cockpit voice recorder for EgyptAir Flight 804 has been found but is damaged, an Egyptian investigative committee said Thursday, a day after the government said it found the wreckage of the ill-fated flight.
“The device was damaged and the retrieval process was conducted in several stages,” the committee said in a statement.
It said a vessel used equipment to pick up the memory unit, which is considered the recorder’s most important part.
The Airbus A320, which had 66 people aboard, crashed May 19 in the Mediterranean Sea on a flight from Paris to Cairo. Authorities have been searching for wreckage and the plane’s flight data and cockpit voice recorders for insight into what happened.
The cockpit voice recorder is one of the so-called black boxes for which searchers have been looking. It captures sounds on the flight deck that can include conversations between pilots, warning alarms from the aircraft and background noise. By listening to the ambient sounds in a cockpit before a crash, experts can determine if a stall took place and estimate the speed at which the plane was traveling.
The recorder is being transferred to Alexandria, Egypt, for the investigation, the statement said.
Wreckage was found in several places. The ministry did not specify the size or the location of the parts that were found.
Searching for black boxes
Searchers haven’t found the other “black box,” the flight data recorder, which gathers 25 hours of technical data from the airplane’s sensors, recording several thousand distinct pieces of information. Among the details investigators could uncover is information about the plane’s air speed, altitude, engine performance and wing positions.
Conflicting reports over final moments
Two weeks ago, a French naval vessel detected underwater signals from one of EgyptAir Flight 804’s so-called black boxes, investigators said.
Specialized locator equipment on board the French vessel La Place detected signals from the seabed in the Mediterranean, the investigative committee said in a statement.
The director of the BEA, France’s air accident investigation agency, later said it had confirmed the signals were from one of the recorders on the plane.
“The signal of a beacon from a flight recorder could be detected. … The detection of this signal is a first step,” said BEA Director Remy Jouty in a statement.
The John Lethbridge, a vessel contracted by Egypt for the search, recovered the cockpit voice recorder.
Once they’re found, the black boxes will be brought to Egypt, a civil aviation ministry official told CNN. That’s standard procedure, the official said, similar to what happened in November with the recorders from Metrojet Flight 9268, which crashed in Egypt’s Sinai Peninsula.
Data recorders have been fixtures on commercial flights around the world for decades.
Four scenarios on EgyptAir Flight 804
In several cases – such as the 1996 crash of TWA Flight 800 or the crash of American Airlines Flight 77 on September 11, 2001 – authorities had hoped to find clues in the recorders, only to discover that the data inside had been damaged or the recordings had stopped suddenly.
