How many aircraft are affected?
Copies with faulty Rolls-Royce engines that drive dreamliners can have far greater consequences than it seemed to be yesterday. – We have eight planes in the first generation, they can theoretically involve. The other three have new generation engines, which are not cluttered with design flaws – tells us a LOT person
Spokesman Adrian Kubicki confirms that for the moment two machines will not break through. endoscope. ). The next step is to inspect the motors in the following machines. – Their defect seems to have a constructive character, so we must take into account that the situation can be repeated. It is well known that this will not happen at the same time – says Adrian Kubicki.
The industry claims that on a worldwide scale the problem potentially concerns more than 700 aircraft that will have to undergo replacements or repairs of Rolls-Royce records. – That's 1.4 thousand engines. Such a scale exceeds the production and financial capacity of the British business – condemns our conversation.
Can this situation cause inconvenience to LOT passengers?
It all depends on the magnitude of the problem, and it is not known yet. In response to emerging issues at Rolls-Royce, a new engine maintenance program will be prepared. He predicts that every few weeks must be carried out a 1000 Boroscope Motor Tent, inside which to look for microphages on turbine abrasives. After such a test, it is decided whether the engine can continue to run, s' it must be removed and replaced (or repaired). This situation creates a lot of uncertainty for carriers, also in flight. It is not known if the Dreamliner once authorized to be used after such an inspection, following the next few weeks will not be founded. – Before each endoscope we hold our breath – stresses the person LOT.
Adrian Kubicki admits that it is difficult to predict how long this situation can last. – Today, our goal is to maintain the level of up to two dreamliners removed from the operation. Of course, we will ensure that the entire fleet is effective – says the spokesperson
As we hear, LOT must carefully plan the retina in the current situation. For now, the carrier focuses on the attack of the holes. To this end, on July 24, instead of one of the two dreamliners to land, a Neos line plane with zaog was rented. After the second ground 787, the new machine will be replaced, repainted in white and red. From here the end of next year, LOT 's Dreamliner fleet should be expanded to 15 units.
But it's just turning off the stains. LOT will soon forget to open new roads. Nor is it certain that the replacement aircraft that LOT will acquire will meet the standards of the new Dreamliner – all depends on the availability of the machines on the short-term rental market.
Engines defective threaten the safety of passengers
Royce is convinced that there is additional security measures. We also learn that the Boeing construction allows an efficient engine to reach the airport safely, four hours away. Other applications of internal fluids "B787 Fleet Safety Bulletin" (to which the first issue of "Fakt"). – In LOT Polish Airlines, the B767 cabs equipped with General Electric engines, which have probably been the subject of two holdbacks for twenty years, give us a sense of security such as the removal of an engine in the The air did not increase the pressure. The probability of the second engine breaking in the same flight was minimal. Rolls-Royce will tell us that it's not true. The choice of one engine increases the probability of failure of the other – it results from the bulletin. LOT ensures that he makes every effort to ensure that passengers do not experience these transient problems.
Will LOT apply with claims to Rolls-Royce?
Yes, it's almost out of place. The game includes canceled cruises or aircraft rentals instead of dreamliners. However, it is the right time for a decisive action against RR. For the moment, it is to be feared that letting go of the claims – not only of LOT, but also of other carriers, whose engines often touch our lines – could seriously affect the situation of Rolls- Royce, and thus the faulty engine maintenance process.
– If on a global scale you must quickly replace 1.4 thousand. Motorw, that exceeds RR's financial and production capabilities – one of our interviews convinces. As he adds, the British company has adopted a tactic, according to which it is impossible to negotiate a place in the queue for engine repair. The detection time of the defect is rather decisive
Is the replacement of Rollup Royce by General Electric involved?
Although this is theoretically possible for the Boeing, it would be a logistically complicated operation. In addition, current engines are rented and accounted for by the number of LOT cycles. – Another thing is that the competition knows the situation well and feels its advantage. As a result, it can be expected that such a GE engine will have to pay a lot – says one of our interviews. Unofficially, you will pay $ 60 million. for one, and each 787 needs two engines
Is the Cancun plane with cruise number LO6506, whose problems of "Fakt" of yesterday, are headed to Miami, after detecting problems with the right engine, redirected to New York?
According to LOT press spokesman Adrian Kubicki – no. At no time did the plane fly over Florida. According to the national carrier, the aircraft crew complains first of all of the engine problem, especially vibration, and then discovers the oil pressure problems. These defects only affect one motor. But a combination of these reasons pilots stacks to make a decision on the emergency action at JFK Airport in New York. The winding maneuver was made with two efficient motors. By the time the problems intensified, the captain decided to turn off the engine and intervene on one of them
. That was does the engine stop and can the pilot safely approach the other? preventively, not as a result of failure. Adrian Kubicki points out that the remote control makes the engine to start it before the action, if weather conditions, for example, require it. By proceeding, when the crew is flying only on an engine, determines the ETOPS procedure. "Extended Range Twin Operations" is a manual that allows twin-engine aircraft to operate on long haul flights for safety reasons – reserved for machines with more than two engines (less losses than one engine per engine). ratio to three active people than the loss of half). The ETOPS procedure describes what the pilot must do to get closer safely, with only a functional training.
According to the engine manufacturer's instructions, the 787 Dreamliner, or Rolls Royce, can fly safely on a Trent 1000 for four hours. PLL LOT, however, opts for more restrictive rules, reducing the maximum flight time on a three-hour engine. – The flight time from the moment the engines are off is two hours, that is to say below the acceptable value. There is no way to order procedures – explains Kubicki. The experienced LOT pilot Tomasz Smlski will also present his position, that the study regarding the event was used in the said text "Fakt" in a way suggesting that he recommends an immediate touch of the machine. – Going to the second circle (that is to say picking up the plane during the landing due to unforeseen circumstances) is possible with a single motor – the translators
Who decides where to land?
It is always an individual responsibility of the captain. As Smlski notes, the pilot at the time of making the decision, still on two efficient engines, did not know how the passenger location costs were distributed and how the US administration approached visas for the Poles (a plane from Cancun in Mexico). US visas), such as the arguments were cited as reason to change the airport to follow. He also admits that as a pilot with a 30-year term, he would make the same decision, that is, that he would be traveling to New York as it is from a well known airport for LOT flights (flight no. LO6506 piloted by another captain).
The Federal Aviation Administration, a civil aviation authority in the United States, provides no explanation from LOT, which proves a positive assessment of the US subsidiary on the carrier's operation Polish. The merger of the proceedings could lead to the introduction of a flight ban for LOT in the United States
