Incident: Norwegian B738 at Kristiansand on Nov 4th 2016, "racing start"

A Norwegian Air Shuttle Boeing 737-800, registration LN-NII performing flight DY-277 from Kristiansand to Oslo (Norway), entered Kristiansand's runway 04, began to accelerate for takeoff, the crew rejected takeoff at low speed and stopped the aircraft after about 230 meters. The aircraft remained in position for about 5 minutes, then accelerated for takeoff again and departed. The aircraft stopped the climb at FL150 and continued to Oslo for a landing without further incident about 40 minutes later.

Radar data confirm the aircraft rolled about 230 meters upon first acceleration, stopped for about 5 minutes, then departed but did not climb above FL150 (while usually the aircraft would climb to above FL300).

On Nov 14th 2016 a source told The Aviation Herald, that the crew received a takeoff configuration warning and rejected takeoff shutting down both engines, which caused all electrics to shut down as well including cabin lighting. While the flight crew was restarting the engines, cabin crew walked the aisles to calm passengers, the flight attendants expected another call by the crew to take their seats prior to takeoff, however, suddenly - with cabin crew still around the cabin in the aisles - the engines accelerated for takeoff and the aircraft departed with the cabin crew rushing to their seats. Climbing out of Kristiansand (usual cruise level FL300) the crew received a cabin altitude warning and levelled off at low altitude, it was later found the air conditioning systems had not been activated. The aircraft was operated by flight crew from Go2Sky and a cabin crew from Norwegian Air Shuttle.

LN-NII is in the process of being handed over from Norwegian Air Shuttle to Go2Sky, the actual transfer of ownership is expected by early January 2017.

On Nov 14th 2016, immediately after receiving the above report, The Aviation Herald contacted Norway's AIBN to see, wether the occurrence was known and is being investigated. On Nov 23rd 2016 the AIBN responded stating: "The AIBN has not received any report matching your information (Operator, Registration, date, airport)."

In the following The Aviation Herald received information that the occurrence has now been reported to the AIBN and shot off another e-mail on Nov 30th 2016, in addition the occurrence made it onto a number of pilot fora being reported by different sources, another source contacted The Aviation Herald directly confirming the first source's narrative. On Nov 30th 2016 the AIBN informed The Aviation Herald, that all investigators were out of house for a seminar, it would take a couple of days until a response was possible.

The second source told The Aviation Herald, that the first officer, right after receiving the takeoff configuration warning, moved both engine start levers to shutoff which effectively shutdown both engines and generators leaving the aircraft dark on the runway. The captain subsequently started the APU, thereafter both engines were started again, then the crew accelerated for takeoff without informing anyone leaving a completely startled cabin crew in the cabin, who were trying to re-assure passengers. Following landing in Oslo the cabin crew decided to disembark and not continue schedule.

On Dec 5th 2016, while still waiting for reply by AIBN to the second inquiry, The Aviation Herald received further evidence confirming the occurrence enabling this coverage.

According to the evidence cabin crew reported that the aircraft departed Kristiansand with a delay of 2 hours following difficulties with the departure/arrival slots. Cabin crew provided a "cabin and galley secure" to the flight crew, the aircraft entered the runway and accelerated when suddenly all power was lost, the cabin went dark and the emergency lights activated. Cabin crew inquired with the flight deck but did not receive any reply that could be understood (there were language problems involved). Understanding that the flight crew was busy and expecting that the crew would call "be seated for takeoff" the flight attendant left the flight deck recommending to the flight crew to make an announcement to have the passengers re-assured, the announcement was made but confused the passengers, a number of passengers called for attention and wanted to get off the aircraft. While the flight attendant was in aisle at the passengers trying to re-assure those passengers the engines accelerated to takeoff power prompting the flight attendant to rush back to her seat and strap in. About 4-5 minutes after becoming airborne an alarm could be heard from the flight deck, the aircraft levelled off and the alarm became even easier to hear. The flight attendants decided to check the cockpit to make sure the pilots were awake, all flight attendants detected there was something wrong with the cabin pressure. Upon calling the flight deck there was no response, cabin crew attempted to enter the cockpit using the emergency code, while the code was entered the first officer responded and opened the door, however did not provide any information as to what was happening. Cabin crew decided to connect their oxygen masks to the portable oxygen bottles. The passengers noticed something was wrong. Finally it emerged they were about to land in Oslo in about 9 minutes, the cabin was cleared for landing, the flight crew called the cabin crew to take their seats for landing and the aircraft landed. After landing cabin crew insisted the flight crew would explain to the passengers what had happened, however, the announcement was unclear just mentioning a wrong switch. Cabin crew was alerted by the break down of crew communication. The occurrence was witnessed by a number of deadheading flight crew of Norwegian Air Shuttle.

Go2Sky B738 at Kristiansand, "racing start"

Attirato dal titolo leggo su avherlad di questo episodio.

In pratica, se ho ben capito, l'aereo si arresta dopo 230m causa un 'takeoff configuration warning' ed il f/o spegne i motori lasciando al buio la cabina.
Gli assistenti sono impegnati a tranquilizzare i passeggeri (alcuni vogliono scendere non ricevendo alcuna spiegazione su cosa stia succedendo) quando i piloti riprendono la corsa di decollo con la cabina non ancora pronta.
Come se non bastasse per un problema di pressurizzazione dovuto ad un errore ancora dei piloti, il volo proseguirà a bassa quota fino alla destinazione finale.
Durante il volo inoltre un assistente, presa coscienza di un problema di pressurizzazione e non ottenendo alcuna risposta dal cockpit, sarà costretto ad entrare con il codice di emergenza. Di nuovo non otterrà nessuna spiegazione su cosa stia accadendo, tanto che gli assistenti collegheranno in via precauzionale le proprie maschere alle bombole di ossigeno portatili.

Il personale di cabina, una volta a terra, si rifiueterà di proseguire nella tratta successiva con gli stessi piloti.

Da semplice passeggero non sono in grado di giudicare quanto poco professionale sia stata la condotta dei piloti.
Trovo però particolarmente inquietante le difficoltà dei piloti nel comunicare con gli assistenti, il fatto che l'agenzia per la sicurezza norvegese, interpellata da avherlad, non fosse a conoscenza dell'accaduto e, soprattutto, che i due piloti siano attualmente in servizio sulla stessa tratta.

chiedo scusa, avevo fatto una ricerca con go2sky e non era uscito niente.
Prego i moderatori di cancellare.

Direi che è meglio tenere un thread separato.
