Incidente MD11 Lufthansa Cargo a Riyadh


Attenzione, Alitalia comprò anche gli MD11 all PAX.

Ho infatti già spiegato che per errore in quel momento avevo invertito il destino degli MD-11 dopo il servio pax in AZ. Da com'è è in realtà cioè MD-11 All Pax a LH Cargo e MD-11C a AZ Cargo, mentre scrivevo il post avevo focalizzato l'esatto opposto.
 
menomale, fa molto piacere che i piloti se la siano cavati e siano già stati in grado di chiamare casa.
Adesso senza commenti, senza polemiche aspettiamo l'inizio e la fine dell'investigazione ufficiale che un giorno ci dirà esattamente cosa sia successo e insegnerà qualcosa di nuovo in fatto di safety.
Il mio unico appunto è che il crew ha dovuto gestire l'emergenza durante la procedura di atterraggio in quanto avevano già rilevato il fuoco, che quindi di per sé ha influenzato la condotta del velivolo (e sembra che ciò sia stato già appurato dalle autorità)
 
Parrebbe, e il condizionale è doveroso, che NON ci fosse fuoco in stiva prima dell'atterraggio, almeno stando a queste (qualificate) affermazioni tratte da Avherald.com

Lufthansa Cargo said on Jul 30th, that they have no indication of an inflight fire.

GACA's head of the aviation safety department Abel Rahman Bukhari said on Jul 31st, that preliminary investigation results suggest, that there was no inflight fire prior to touch down. The undercarriage of the aircraft was severly damaged in the landing causing the airplane to veer off the runway. The impact caused the fire on board.

The NTSB reported on Jul 31st, that the aircraft "reportedly caught fire after a hard landing at the King Khalid International Airport, Riyadh, Saudi Arabia".
 
Sempre da Avherald:
A statement by Lufthansa provided to Lufthansa employees on Lufthansa's internal website around Aug 10th said, that the black boxes have been analysed by the German Bureau for Aviation Accident Investigation (BFU). The results indicate, that the airplane touched down normally in the touch down zone, however two more ground contacts followed which caused the rear of the aircraft to fracture just aft of the main gear. After 2400 meters (7880 feet) the airplane departed the runway 33L to the left, at this stage the nose gear collapsed. The airplane came to rest after another 375 meters (1230 feet). The crew left the airplane via slide 1L. Further information can not be provided due to the ongoing investigation, every (internal or external) statement must be authorised by Saudi Arabia's investigator in charge. The investigator hopes to release a preliminary report in fall 2010, which requires interviews with the crew however. The interview has been scheduled for next week (Aug 16th-20th). A final report is expected in about a year. The wreckage has been removed from the accident site and is currently being dismantled. Lufthansa Technics checks whether some of the undamaged parts can be re-used, all the rest is going to be scraped in Saudi Arabia.

The German BFU stated, that the airplane bounced after first touch down and broke on next touch down.

The German news magazine Spiegel reported on Aug 14th, that ground witnesses at Frankfurt Airport confirmed the cargo contained highly inflammable chemicals as well as other hazardeous goods like weaponry and other military goods. According to that report the chemicals were located exactly in the area where the fire started. Lufthansa Cargo did not comment on that report.

Crashed MD-11F bounced heavily during Riyadh landing

German investigators have disclosed that the Lufthansa Cargo Boeing MD-11 freighter which crashed and burned on landing in Riyadh made three heavy contacts with the runway.

It hit runway 33L with a vertical impact of about 2g, says the German investigation agency BFU, before lifting off again.

This was followed by a second contact of 3g and another at 4.3g before the tail structure behind the main landing-gear failed.

The MD-11F veered off the left side of the runway about 2,400m (7,900ft) after the initial touchdown and careered for a further 375m in the sand before coming to a halt.

Two pilots were the only occupants of the tri-jet. One of them was seriously injured, the other only lightly.

Lufthansa Cargo's flight LH8460 had been arriving after a flight from Frankfurt, with 80t of cargo on board, when the accident occurred on 27 July.
