    Spanair accident analysis

    According to what I know about the airplane and what I gathered from different sources here is my guess work about the accident.


    The heavily loaded MD82 aircraft, bound for the Canary Islands, smashed to the ground tail-first near Barajas airport on August 20 after struggling to climb after an unusually long take-off run. Only 18 people survived.fficeffice" />>>
    Spanair flight JK5022 taxied out to the runway and then turned back to the terminal after the pilot reported a fault in the instrument that measures outside temperatures. >>
    When the technicians gave the green light an hour later, the 15-year-old aircraft returned to the runway, accelerated to more than 150mph and began to lift a few feet into the air and the MD82 aircraft crashed into the ground near the end of the runway. A combination of pilot error and an electrical failure has emerged as the possible cause of the crash of a Spanair airliner at Madrid airport last month that killed 154 people. The crew of the MD82 jet failed to extend the wing flaps that are vital for take-off and an automatic system did not alert them, according to media leaks from the Madrid investigation. >>
    Data from the “black box” recorders of the Spanair jet showed that the two engines worked normally up to the crash but that the flaps were not set. The flaps on the wing’s trailing edge and slats on the leading edge are essential for lift on take-off. They are one of the three “killer items” that pilots triple-check before take-off. TRIM, FLAPS, SPOILERS>>
    The cockpit voice recorder, recovered from the crash, showed that the crew had confirmed “Flaps OK, Slats OK” during their reading of the check list, according to Spanish reports. >>
    A loud audio alert "BEEP BEEP FLAPS, BEEP BEEP SLATS “should have warned the crew of the wrong flap setting the moment they applied take-off power, but it did not work. The devices were installed on airliners decades ago because the failure of pilots to set flaps caused so many accidents. Two other alarms — warning of nearby ground and imminent stall — did work in the Spanair aircraft as the pilots struggled to control it. According to evidence gathered so far this accident look like a copy of previous MD 82 The US National Transportation Safety Board determined that the loss of a Northwest Airlines MD-82 at almost exactly 21 years before the Spanair crash, was due to the crew's failure to use the taxi checklist to ensure that the flaps and slats were extended prior to the take-off roll.>>


    As was the habit of all accident investigators here again accident news started with engine fire/explosion then with reversers and finally wrong take-off configuration. İn lace>Spainlace> is quoting them adding their own little "twists" to the story to make it fit better a "mechanical" (electrical) malfunction and downplay the pilots (potentially) forgetting to set wing configuration correctly for take-off.

    "An electrical malfunction caused the accident".???>>
    >>
    İt is unbelievebale they still can’t find any clue if the flaps and slats extended or not. There are 5 sources to gather this information from the wreck.>>
    1-Wing pieces on the crash site. >>
    2-Cockpit ındicators>>
    3- Flap slat quadrant>>
    4- position of slat actuators>>
    5-Recorders.


    >>
    When a pilot moved the flap handle to extend he watches for a blue light and the proper indication on the flap gauge., The checklist called for checking the slats/flaps and then the takeoff warning configuration. To do that thrust was applied when start taxiing, if the the slats up, we would hear the warning horn... If the slats were set, No warning...if a warning was heard, the slats were not set.
    When reach the runway, check the slats/flaps once more...not a checklist item but a KILLER ITEM . FLAPS, TRIM, SPOILERS will all kill you on takeoff if not properly set.

    İMPORTANT CLUES FOR ACCİDENT: >>
    İn order to Take Off without flaps and slats pilots must>>
    1-Failed to do proper preflight. (Checking all circuit brakers)>>
    2- Failed to do proper checklist check.>>
    a) Did not check the flap position gage, slat light, position of flap handle on the pedestal.>>
    3- When powered up both engine did not received take off warning (Setup procedures was to advance the thrust levers prior to engine start and test the CAWS (Central Aural Warning System). If it worked properly, we would hear a "BEEP BEEP FLAPS, BEEP BEEP SLATS, )>>
    a) Due to failure to check circuit brakers during preflight failed to see GND CONT. RELAYS circuit braker was out.>>
    b) because of this CB was out ( Or a fault in the system)hence the failure of TAT probe heat problem, strob light being on and take off configuration warning failure occurred.>>
    c)During second refueling the fueler seen the strobe lights were on. (They only work in air or if the aircraft think it is in the air) >>
    The probe heating on the ground and fueller seeing the strobe lights on is an indication of aircraft was in air mode.,>>
    takeoff configuration warning/groundshift mechanism were not working the symptom being the heating of the RAT on the ground and the strobe lights during fueling..

    This becomes second piece of evidence of an air/ground system malfunction which put the aircraft on flight mode and the failure of take off configuration warning and the RAT probe heating.

    On rotation when the A/C failed to climb properly, the crew realised what had happened and instinctively tried to stop and grabbed the reversers, (reports says one reverser locked out for being inop.) .After accident one reverser found on locked Full reverse thrust position. >>
    THE THRUST REVERSERS didn't cause or contribute to the crash.

    The ENGINES were producing proper and normal thrust for takeoff.

    İn an incident with another MD83. crew failed to comply with the checklist and did not extend flaps and slats. After rotation experienced stall and 50 deg bank left and then recovering and then right 50 deg. This whent on for a few times back and fwd and somehow manage to get the aircraft stable with selecting gear up and just continue towards the slow hill at about 100 ft of altitude. Crew then found out flap handle in up position. How was that possibe ?? This is an officilal NTSB report and they found c/b -L/H GND CTRL RLY OUT when landed safely. >>
    >>
    PİLOT’S>>
    İt doesn´t matter how long one is flying an aircraft type and how experienced one is always do.>>

    3- Check all aural warnings>>
    4- Do a proper check list check.>>
    5- Double check the killers. TRIM, FLAPS, SPOILERS...

    >>
    AİRPORTS:>>
    1- Must install cameras specifically to monitor take-offs and landings for safety or flight operations performance.>>
    2- Şhould level the ground around all active runways and remove or shorten the obstacles. (Prevents eccesive damage to airplanes and unnecessary loss of life. Permits rescue vehicles faster response time and more efficient operations)>>

    I had a passenger telling us AFTER the flight that one of our speedbrake panels was fluttering. Of course we shrugged it off, but called for an engineer anyway just to be sure, who subsequently found a major rupture in the panel's hydraulic actuator, grounding the plane for the rest of the day. NOW I wish that pax had spoken up in flight>>
    > >
    I know of one case in which the spoilers deployed on landing of a 737 and when the handle was moved to retract them, the cable broke...so the handle moved to the correct spot, the light that said the spoilers were extended went out BUT THE SPOILERS WERE STILL EXTENDED. It was missed onthe walk around...but some guys in back on the next flight, deadheading noticed and stopped the takeoff in time...THERE WOULD HAVE BEEN NO WARNING.

    WHILE it takes bravery to speak up to avoid a disaster you must be brave and speak up if you :

    1. know something about planes

    2. see something wrong.

    A passenger noted something wrong with our flaps on landing...we extended them at the gate and wow, was there something wrong!!! grounded!

    My guess about the accident is with over load ,bad trim ,low EPR, hot temperature and a slight tail wind take off without flap/ slat extended.
    Due to inop TO conf.warning. And the tocw is inop due to pulled grd prox cb.>>
    > >
    The DC9/MD80/MD90 series is one of the finest, strongest planes built. It is a joy to fly if you are a good stick and rudder pilot. It has few computers and the pilot is directly in charge of just about everything.>>

    Uçuş güvenliği olgusuna bende bir vecize ya da özdeyişle katılmak istiyorum.Dünyaca ünlü ve nobel ödülü almış bir yazardan uyarladım.

    'Uçuş güvenliği damarlarımızdaki kan gibidir.Her an hissetmeyebiliriz ama yokluğunda yaşayamazsınız..' Geçtiğimiz günlerde
    yaşamını yitiren J.Saramago'nun özdeyişini hayatın her alanına atfedebiliriz.
    Lakin havacılığında özü, temeli işte o kan..
    'Uçuş güvenliği ' ..
    O olmadı mı, ölürsünüz. Nitekim yaşananlar bunun kanıtı değil mi ?

    Özgün özdeyiş aslında şöyle :
    '' Damarlarımdaki kan gibisin, varlığını her an hissetmiyorum ama yokluğunda yaşayamam." (J.Saramago).

    SPANAIR KAZASININ SORUMLUSU PİLOT MU?


    İspanyol havayolu şirketi Spanair'in, 2008 yılının Ağustos ayında meydana gelen ve biri Türk toplam 154 kişinin ölümüne yol açan uçak kazasına, pilot dikkatsizliğinden kaynaklandığına kanaat getirdiği belirtildi.

    İspanyol gazetesi El Periodico'nun haberinde, kalkış sırasında Madrid Barajas havaalanı yakınlarına düşen uçakla ilgili Spanair şirketinin yürüttüğü araştırmanın tamamlandığı aktarıldı. Spanair'e göre, uçağın düşmesine neden olan temel faktör ''pilot dikkatsizliğine bağlı insan hatası'' olarak gösterilirken, pilotların kalkış anında uçağın kanatlarındaki flapları harekete geçirmeyi unuttukları ve manuel olarak kalkış yapmaya çalıştıkları savunuldu. Raporda, pilotlarının dikkatinin dağılmasındaki etkenlerden birinin, kimliği açıklanmayan bir uçuş görevlisinin pilot kabininde olması olarak ifade edildi.

    Türk vatandaşı Mustafa Erdil ile birlikte 154 kişinin hayatını kaybettiği kazayla ilgili davalar halen devam ederken, teknik arıza yüzünden rötar yapan uçağın kazadan önceki son kontrolünü yapan 2 teknik uzman, görevini eksik yerine getirme ve uçuş güvenliğini sağlamama suçlarından Madrid'de yargılanıyor.

    Rötar olmasın derken felaket yaşanmış

    İspanya'nın başkenti Madrid'deki Barajas havaalanında, Spanair'e ait yolcu uçağının düşmesine, acelecilikten kaynaklanan teknik hata ve pilot hatalarının neden olduğu açıklandı.

    Mahkemeye sunulan ve İspanyol basınına sızan bilirkişi raporunda, Spanair teknik servisinin "uzun süreli rötarı önlemek için uçaktaki arızanın gerçek nedenini bulmadan uçağa kalkış izni verdiği" belirtildi.

    Pilotların uçaktaki arızayı yanlış tespit ettikleri, teknik servisin de arızanın ana sebebini tespit edemediği ileri sürüldü. Bilirkişi raporunda, teknik servis ve pilot hataları dışında, uçağın kalkışa uygun hale getirilmesi için kanatlardaki flapsların açılmaması, uyarı sistemi TOWS'un çalışmaması, yetkililerin önemsememesi ve uçakta imalat sorunu gibi unsurlar da, kaza sebepleri arasında gösterildi.


    Spanair'e ait MD-82 tipi bir yolcu uçağı 20 ağustos 2008'de kalkış sırasında düşmüş, kazada Mustafa Erdil adlı bir Türk vatandaşı dahil toplam 154 kişi ölmüştü.

    18 kişinin yaralı olarak kurtulduğu kazayla ilgili davalar halen devam ediyor.
