Crash B767-300 BCF Houston

Messaggio da JT8D » 24 febbraio 2019, 14:35

Un B767-300 BCF di Atlas Air (N1217A), che operava per conto di Amazon Prime Air, in fase di avvicinamento a Houston è stato perso dai radar ed ha impattato in acqua a circa 30 nm da Houston Intercontinental Airport.

"The NTSB dispatched a Go-Team to investigate the crash of a cargo jet near Baytown,TX. In a very first brief preliminary statement the NTSB reported the aircraft was in a descent characterzized normal, when at 6300 feet it began what the NTSB characterizes a very rapid descent. A simultaneous loss of radar and radio contact occurred".

Sta girando un video amatoriale colto sostanzialmente per caso e non "focalizzato all'aereo".

Ora, al netto della prospettiva, dell'assenza di punti di riferimento vicini al piano su cui volava l'aereo, dei movimenti di chi teneva il telefono in mano etc etc etc ho avuto la stranissima sensazione visiva (non attendibile...) che si muovesse troppo lento. L'ultimo dato di flightradar parla di 254 nodi... non capisco.

Che le cose siano così, non vuol dire che debbano andare così. Solo che, quando si tratta di rimboccarsi le maniche e incominciare a cambiare, vi è un prezzo da pagare, ed è allora che la stragrande maggioranza preferisce lamentarsi piuttosto che fare.

"On Feb 24th 2019 the NTSB reported in a press conference, that the aircraft was on a standard arrival route from the southeast, the crew checked in with Houston Approach at about 18,000 feet about 76nm southeast of Houston Intercontinental Airport at about 12:30L, ATC advised there was light to heavy rain ahead and offered vectors around the weather. At about 12:36L the aircraft was cleared to descend to 3000 feet. At 12:41L radio and radar contact was lost when the aircraft was at 240 KIAS at about 6000 feet. A surveillance video was located by the NTSB from the Chambers County Jail about 1.4nm from the impact area showing the aircraft in a steep descent in a steep nose down attitude, the video shows the aircraft for about 5 seconds. There was no distress call. The main wreckage location is oriented in a northwesterly direction and is about 200 yards long and 100 yards wide. Wings and landing gear are further to the northwest. The NTSB is still searching for the back boxes. No hazmat was on board. The fuel load is not yet known, it is anticipated however that the fuel tanks were breached at impact and all fuel was released. There is no information available yet how long it took from entering the steep descent until impact. There were no attempts, according to the surveillance video, to turn or pull up during the last moments of flight. The pingers attached to the black boxes can not be heard, possibly because of being buried in the mud and effectiveness being reduced. The surveillance video will be placed into the NTSB docket and will be released to public when the docket is going to become public. Two bodies were recovered from the crash site so far. Within the NTSB conference the Sheriff stated that they did not find the crash site due to fuel but due to debris. There was very little if any fuel around."

"On Mar 5th 2019 the NTSB reported the download of the CVR was successfully completed, the last portion of the accident flight is available on the 2 hours' recording, the quality of the recording however is poor and it was difficult to determine what was being said, occasionally required advanced filter techniques. The aircraft was being vectored for an approach to Houston Intercontinental's airport's runway 26L. The NTSB stated: "Crew communications consistent with a loss control of the aircraft began approximately 18 seconds prior to the end of the recording." The FDR was also successfully read out, 54 hours of flight data spanning 17 flights were downloaded. The recorder stores about 350 parameters. The investigators are currently verifying and validating the FDR data. A transcript of the CVR is estimated to be compiled during the next week (Mar 11th and following)."

Ieri è stato rilasciato un video da una telecamera di sorveglianza, con gli ultimi secondi del volo:

Da AVHerald:
On Mar 12th 2019 the NTSB provided an update stating:

The wreckage was situated in a shallow muddy swamp area, and the main debris field was oriented east to west and about 350 yards long by about 200 yards wide (figure 1). One engine and some landing gear components were found beyond the main debris field to the west. Less dense components and a large portion of the cargo floated southward and were recovered up to 20 miles away.

The NTSB reported:

Air traffic control communications and radar data indicated the flight was normal from Miami to the Houston terminal area. About 12:30 pm the pilots contacted the Houston terminal radar approach control (TRACON) arrival controller and reported descending for runway 26L; the airplane was at 17,800 ft with a ground speed 320 knots.

At 12:34, the airplane was descending through 13,800 ft, and the controller advised of an area of light to heavy precipitation along the flight route and that they could expect vectors around the weather.

About 12:35, the flight was transferred to the Houston TRACON final controller, and the pilot reported they had received the Houston Automatic Terminal Information System weather broadcast. The controller told the pilots to expect vectors to runway 26L and asked if they wanted to go to the west or north of the weather.

Radar data indicated the airplane continued the descent through 12,000 ft with a ground speed of 290 knots, consistent with the arrival procedure. The pilots responded that they wanted to go to the west of the area of precipitation. The controller advised that to do so, they would need to descend to 3,000 ft expeditiously.

About 12:37, the controller instructed the pilots to turn to a heading of 270°. Radar data indicated the airplane turned, and the automatic dependent surveillance-broadcast (ADS-B) data indicated a selected heading of 270°. The airplane was descending through 8,500 ft at this time.

About 12:38, the controller informed the pilots that they would be past the area of weather in about 18 miles, that they could expect a turn to the north for a base leg to the approach to runway 26L, and that weather was clear west of the precipitation area. The pilots responded, “sounds good” and “ok.” At this time, radar and ADS-B returns indicated the airplane levelled briefly at 6,200 ft and then began a slight climb to 6,300 ft.

Also, about this time, the FDR data indicated that some small vertical accelerations consistent with the airplane entering turbulence. Shortly after, when the airplane’s indicated airspeed was steady about 230 knots, the engines increased to maximum thrust, and the airplane pitch increased to about 4° nose up and then rapidly pitched nose down to about 49° in response to column input. The stall warning (stick shaker) did not activate.

FDR, radar, and ADS-B data indicated that the airplane entered a rapid descent on a heading of 270°, reaching an airspeed of about 430 knots. A security camera video captured the airplane in a steep, generally wings-level attitude until impact with the swamp. FDR data indicated that the airplane gradually pitched up to about 20 degrees nose down during the descent.

The NTSB reported the captain had been with the company since 2015, held an ATPL and had accumulated about 11,000 hours of flight experience, thereof about 1250 on type. The first officer was with the company since 2017, also held an ATPL and had accumulated about 5000 hours of flight experience with 520 hours on type.

The airplane then pitched nose down over the next 18 seconds to about 49° in response to nose-down elevator deflection. The stall warning (stick shaker) did not activate".

NTSB ha aperto il 19 dicembre il public docket. Al momento non vi è ancora un preliminary report.

:shock:

In effetti non è ancora molto chiaro quanto accaduto.
