#A320 Crash History Verification Of A

The Airbus A320 is the second best-selling airliner of all time behind the Boeing 737. Flight PK-8303 from Lahore was about to land in Karachi when it crashed at the Jinnah Garden area near Model Colony in Malir, just a minute before its landing. Pakistan International Airlines Fli.SГЈo Paulo-Congonhas Airport, SP (CGH) ( Brazil)The Airbus A320 crashed on Friday in a densely-populated residential area of the city of Karachi, a few days after the coronavirus-induced travel restrictions were lifted in the country. 91 passengers and 8 crewmembers were onboard.As the world is still shocked by the recent Airbus A320 Crashes in Pakistan Heres What Really Happened to Flight 8303. The Airbus A320 operated by Pakistan International Airlines took off from Lahore, Pakistan, for a passenger flight to Karachi, Pakistan. Pakistan International Airlines Airbus A320 with 99 people onboard crashes in Pakistan.

Although it was not possible to verify which type of headache it was, or even to evaluate its intensity, it is possible that this trouble may have influenced his cognitive and psychomotor capabilities during the final moments of the flight, when the unpredictability of the situation demanded a higher effectiveness of performance. The TAM Express building sustained structural damages that determined its demolition.At a certain moment, during the approach, the PIC reported having a mild headache. The accident also caused 12 fatalities on the ground among the people that were in the TAM Express building.The accident caused severe damage to the convenience shop area of the service station and to some vehicles that were parked there. The thrust lock function is disabled by the movement of the thrust lever, but since this movement did not occur, the number 2 engine remained with that power until the collision.About six seconds after the main gear touched the runway, there was the first activation of the brakes by means of the pedals, which reached the maximum deflection five seconds later.The FDR also recorded the use of the rudder and the differential braking by the pedals as the aircraft veered to the left.Since the runway is at a higher elevation than the surrounding street and residential area, the A320 crossed over the Washington LuГs Avenue, and collided with a concrete TAM Express building and a fuel service station at a ground speed of 96 knots.All the persons onboard suffered fatal injuries. With this action, the autothrust function of the aircraft was disconnected and the thrust lock function was activated, with the purpose of preventing the acceleration to reach the climb power level.As a result, this function froze the number 2 engine power in the value it was at that moment (EPR2 = 1.18).

Thus, there is a high probability that the PIC inadvertently left one of the thrust levers in the вЂњCLвЂќ position, placing the other one first in вЂњIDLEвЂќ and later in the вЂњREVвЂќ position.This factor was considered undetermined due to the impossibility of confirming its contribution in factual terms.Independently of the hypothesis considered, the monitoring of the flight at the landing was not appropriate, since the crew did not have perception of what was happening in the moments that preceded the impact. This procedure consisted in the receding of both levers to the вЂњIDLEвЂќ position during the flare at about a 10-foot altitude, and, after touching down, in activating the only reverser available, maintaining the thrust lever of the other engine in the вЂњIDLEвЂќ position.This procedure, though being more efficient from a braking perspective, could induce the crew to making mistakes, as there were several reports of occurrences in which there was a wrong setting of the levers, motivating the manufacturer to establish a new procedure, months before the accident. Application of the commands - UndeterminedOne of the hypotheses considered in this investigation was that the pilot may have attempted to perform a procedure no longer in force at the time of the accident for the landing with a pinned reverser. Lastly, there was a perception among the crews interviewed that the training through the years and on account of the high demand resulting from the companyвЂ™s growth was being abbreviated.B. In addition, the formation of the SIC was restricted to the вЂњRight Seat CertificationвЂќ, something that proved insufficient for him to deal with the critical situation experienced after the landing.

Influence from the environment - UndeterminedThe operating conditions of the Congonhas runway, may have affected the crewвЂ™s performance from a psychological perspective, considering the state of anxiety that was present in the cockpit.In addition, the lack of luminosity resulting from the operation at night time, associated with the size and color of the thrust levers may have hindered the verification of a contingent inappropriate positioning of those controls during the landing.This factor was considered undetermined due to the impossibility of confirming, in factual terms, the psychological influence of the runway operating conditions and/or lack of luminosity on the performance of the crew.In view of all the operation scenario - the 55 meters added on account of the reverser procedure, the 2. Forgetfulness by the pilot - UndeterminedIt is possible that the pilot has inadvertently left one of the levers at the вЂњCLвЂќ position, while trying to perform a procedure no longer in force for the operation with a pinned reverser.The procedure prescribed for the operation with a pinned reverser had been modified by the manufacturer and, according to the FDR recordings, the procedure in force was known to the crew and executed by them on the leg that preceded the accident.However, as this procedure imposed an increase of up to 55 meters in the calculations of runway distance required for landing, it is possible that the PIC deliberately tried to perform adoption of a procedure no longer in force would characterize flight indiscipline.F.
