PIA teams recover cockpit voice recorder a week after devastating plane crash

The cockpit voice recorder (CVR) of the ill-fated PK-8303, which crashed in Karachi last week, has been recovered from the debris, the Pakistan International Airlines (PIA) said on Thursday.

The national carrier, in a tweet, said that PIA teams, aided by Airbus experts, had been searching "extensively" for the recorder, which will now be handed over to the Air Accidents Investigation Branch (AAIB).

"This will be a key component in the Air Crash Investigation," the tweet read. "PIA teams were searching extensively for CVR aided by Airbus team."

Last week, the Airbus A-320 aircraft that had flown from Lahore, crashed into Model Colony, a residential area near the Karachi airport, after both its engines apparently failed. Only two people survived the devastating crash out of the 99 passengers and crew members on board. The remaining 97 were killed and DNA tests are underway to identify the victims.

The plane made failed attempts to land at the Karachi airport before the crash. Authorities had recovered the flight data recorder (FDR) of the ill-fated aircraft on the day of the crash, but could not find the CVR.

Both FDR and CVR are the two key components of the ‘black box’ of an aircraft. In the present case, the CVR is of more importance because it records all sounds, including pilots’ conversations, in the cockpit.

PIA and AAIB teams along with an 11-member team of Airbus experts and engineers have been scouring the site of the crash for the past three days in order to collect evidence which would help determine the cause of the crash.

It is another proof of the highly unprofessional and ill trained staff of PIA. All flight recorders have inbuilt devices to relay wireless indication signals to locate the flight recorders, even from deep sea. This plane had crashed within the populated area and still it needed the people from the manufacturers of the plane to come and find the recorders.

@blunt, It is property of Air Bus, who can only open it and decode its contents. Its not USB of your laptop or memory card of mobile. Dont stress yourself. And it can only keep a record of around last 30-40 minutes of recording prior to crash, in an encrypted format.

Is there no audio visual tape recordings of all the actions the pilot and the co-pilots actions take, i.e. when was the landing gear lever actuated, recordings of all readings and timings of all gauges, meters, if not then I think this should be introduced. all commercial air crafts should have audio visual cameras in the cockpit to record all actions and sound from any source in the cockpit throughout the whole flight, on the sides of the seats, on the ceiling, at floor level to record leg movement on the pedals. both left hand and right hand movements of both the pilot and co-pilot should be recorded with precise timings, if this is not a standard feature in all air crafts, then it is indeed most surprising, cameras should be located also on the instrument panel in front, to record the facial expressions of both pilot and co-pilot, this will clear a lot of ambiguities which investigators are faced with after a accident.

It is good to know that Cockpit Voice Recorder is found after seven days from debris of crashed aircraft. It will be very much helpful in derterming as what were technical problems that resulted in crash of flight PK-8303 at Karachi. After listening conversation of pilot with Air Traffic Control in an eleven minutes video clip (which shows boarding of passengers and take-off from Lahore Airport) has been released by someone and it has gone viral on social media. Apparently, it seems that there was malfunctioning in the landing gear and wheels were not opened at the rght time, after which continuous sound of beep was heard, which was not only ignored by the pilot, but pilot also did not discussed and communicated the issue with Air Traffic Control. The pilot attempted to land in first attempt through belly of aircraft during which both engines were badly damaged, before the aircraft again went in air for "go-around" to make a second attempt of landing during which aircraft crashed.

I think this voice recorder is tempered with. Both FOR and CAR are equipped with radio signals which helps their recovery. These can be recovered even at great depths underwater and the batteries can last up to 30 days for transmitting the radio signals.

There is an urgent need of forensic detailed report of PIA done on the same lines as sugar report. No doubt there are deficiencies and according to some sources gross incompetence right from the top to bottom.Its gone too far, how once a fine airline has been banned in first world. Inaptitude, incompetence ,greed, corruption, political appointments, lack of national pride are factors for its mess. Heads should roll ,PIA should reborn if not dissolved. Loss of innocent lives is inexcusable.

@Haq, Pakistan should ask a private party/ies or a foreign country to run the national carrier under a new name. The terms of reference should be efficiency, competence, with no interference in its running. There are many airlines which serve as a good example, in fact the national airline was a good example many years ago, all that has gone, we have to recognize this issue and face up to the reality, we are losing precious lives, and millions just to provide jobs ..

FYI (for your information) the "signals" or beacon is only activated if the FDR or the CVR is underwater.

@Brownman, That's the million $ question, my friend. What PIA and the country as a whole does not seem to recognize is that if we did not get to the root cause then it may be repeated. By now all indications are that it was pilot fault. Faults and accidents happen but we must understand what exactly lead to the accident so we can learn and stop it from happening again.

Just as PIA cant have its representative in the inquiry board PALPA cant be part of the committee because its late member is person of interest. No where in developed countries representatives of concerned parties can be part of investigations. If PALPA is insisting and trying to make findings controversial then that could be because available information so far is not favorable for PALPA
