Plane crash in Madrid – black box answer
The first questions unanswered
* The pilot reported a breakdown related to the outside temperature indicator
* Antonio Luna was an expert commander of the damaged aircraft as MD
Madrid .- As with any tragedy of the magnitude of the plane crash yesterday, with 153 dead and more in the early hours after it occurs, the unknowns are precipitated one after another in a sea of official information, rumours, allegations witnesses and experts often contradict each other.
All answers are in the black box, yes. But for the moment are many questions unanswered, mainly by Spanair, which just yesterday provided information on the circumstances of the incident and requested avoid speculation.

As part of the Ministry of Development, a Committee of Inquiry, composed of seven independent persons, is responsible for collecting all data relating to the takeoff of the flight JKK 5022.
* What does the pilot to return after his first attempt at takeoff? The commander Antonio Luna decide to return to the car park, to bring the plane to an inspection, once it has started to roll in track. What looks? What hear? According to company sources indicated late at night, before embarking on the flight, the pilot reported a breakdown related to the outside temperature indicator. According said a member of Seplan in Spanair, failed indicator of icing of the wings and engine. Outside what was the captain due to announce it in the book incident aboard the plane. The book has double sheets, with copies to the maintenance technicians.
* Do solve the problem of maintenance engineers? Sources Spanair assured ‘that was repaired “the problem with the outside temperature indicator” according to the procedures set out by technicians from the company. However, it is unknown whether this judgement could have had connection with the outbreak of the engine that ended up destroying the plane. Those who were technicians inspected the equipment of the maintenance team that the company takes Barajas, according to sources explained Spanair.
* Do Influyó the plight of the company? Spanair is negotiating a record Regulatory Employment (ERE) which seeks to dispose of more than 1,100 workers, including up to 100 pilots. Employees of the company revealed in this newspaper to show that the managers of this ERE that not too many workers, have been proposed to make some sort of strike zeal, which called Alpha plan, and that no worker does nothing but is strictly comply with the functions of his responsibility. This would imply that the pilots will refuse to fly if they detect the slightest flaw in the plane, although not put at risk the flight. Similarly, the technicians would be very scrupulous in their work, the time it takes afternoon.
However, on the other hand, not on aware that suggests that the quality and thoroughness of maintenance has declined in recent times. The company ensures that it meets the requirement and to the letter.
* Is human failure? The commander Antonio Luna was an expert pilot MD planes, such as damaged. Llevaba sailing with them 10 years at a cost of some 700 flight hours annually, according to an acquaintance explained to him that day.
* Do reviews in order? In May 2008 he spent his last regular checkup. Earlier in January, had spent the most comprehensive revision made to them to aircraft, which is to dismantle the equipment piece by piece and re-mounted. Every day, moreover, spends most cursory review. Although the device is 15 years old and engines as well, the pieces are changing.
* Could aborted takeoff? No one reveals how much time passed between the engine explosion and the collapse of the plane, and if there was any prior indication that warned of the judgement. The explosion occurred when the front of the plane had left landfall, but it is unclear whether there were already off the rear. Sure, we had already exceeded the speed of decision (V1), after which the device can not be stopped, and can only continue and try to dominate the machine, whatever failures you have. Although the plane loses power, you can move up with a single engine, according to some pilots explained to this day. The problem is the consequences of the explosion: whether damaged other parts of the plane, including wings and fuel tanks, the plane explodes in a blink of an eye.
* Will this affect other circumstances? Whatever the root cause of the explosion, the pilots brought some influential factors in a critical situation. The altitude at which the airport is situated (in Madrid, 600 meters above sea level) and temperature (about 30 degrees at the time of the accident) affect the engine power, in this case, particularities Barajas at that time could diminish that power.
Pilots taking off before the JKK 5022 noted that there was a wind streak that could affect the stability of the apparatus, especially when the inclination of takeoff is so markedly as the MD aircraft. It can also affect the rebufo of an apparatus that has taken off before. Without doubt, the burden of aircraft is crucial: a larger cargo, passenger and fuel, higher power. The MD-82 was complete and full of fuel to reach Gran Canaria.
* Does the ultimate responsibility? Safety is a shared responsibility among all operators in the air system and, ultimately, the Directorate General of Civil Aviation, the Ministry of Public Works.
