LOT's SP-LRA has been grounded due to mechanical problems/damage to the landing gear. This is following problems with door seals requiring to operate at low altitudes (FL240) and problems with electronics for which it was previously grounded.

It appears that LOT is taking a very safe and cautious approach to all these teething problems, making sure that they fully understand what is happening with the plane and that all issues are fixed before the plane is airborne again.

The flip side is that three or so days of flights have been cancelled, and there are many enthusiasts who booked these flights to experience B788 but flew on a B734 instead.

The good news is that the second B788, SP-LRB should land at WAW at 3:00 pm today ...

I read from a few people who already had the pleasure that the landings at WAW are very rough. Might this be related to the landing gear issue or is there some other type of problem?

Sounds like they have some teething problem which is totally normal and I see it as good behavior of LOT to investigate any problems thoroughly. I remember when AY received the E-jets, the start went surprisingly smoothly, until the winter arrived!

Actually, one of the Polish papers or aviation sites, forgot which, claims that the landing gear problem came up after a rough landing of the flight from PRG at WAW on Tuesday. The next flight to MUC was cancelled and the aircraft has been out of service since.

This is strange. These initial B787 flights are relatively light, with a cap of 175 passengers, not even close to MLW. The weather was OK. In addition, if Polish pilots can successfully land a B767 w 230+ people on board at WAW without landing gear as it was demonstrated last year by Captain Wrona, I am not sure what can be so different with a B787 (?)

On a Czech forum they mentioned Wednesday. If I'm not mistaken, they also said that after that landing LOT didn't use a jetway but the plane was parked on a remote stand straight away.

The plan was to have these intra Europe flights on 787 completed by January 15, 2013.

Then on January 16, 2013 start WAW-ORD-WAW.

and follow early February with WAW-YYZ-WAW and WAW-JFK-WAW (once LP-LRC is in place) and in March WAW-PEK-WAW (once LP-LRD is in place).

With the introduction of B787 aircraft, the old B767 were supposed to be phased out.

There were no scheduled flights on B767 beyond North American and Asian destinations.

There were occasional charter flights (perhaps the ones to TLV) or one-off flights say to LHR to pick up stranded passengers due to adverse weather conditions on prior days (e.g., volcanic ash in 2010)

The second was delivered - but it went tech as well. With regards to the landing, a mod at FT stated "the brake assembly overheated and a titanuim part got damaged". Don't know how accurate that is, but I haven't come across any other info (in English, anyway).

On Friday, flew from Boeing's factory in Everett in the U.S. The second Boeing 787 Dreamliner owned by LOT Polish Airlines. It was supposed to fly to Vienna today, but it broke.
Machine with registration numbers SP - LRB started on Friday at 5.36 Polish time Paine Field airport in the United States. Landed about 15:30 at Warsaw Okecie. About 17:20 the flight was to fly to Vienna. However, according to LOT's spokesman Mark Kłuciński LOT airplane did not take off from Warsaw. Instead a Boeing 737 substituted. The Commissioner explained that the second dreamliner was signaling a fault and noted that the carrier now checks the problem. It will not perform any flights on Friday.

O 17:20 miała wylecieć w rejs do Wiednia. Jednak jak poinformował rzecznik prasowy PLL LOT Marek Kłuciński samolot nie wystartował z Warszawy. Zamiast dreamlinera podstawiono Boeinga 737. Rzecznik wyjaśnił, że w drugim dreamlinerze zauważono sygnalizację pewnej usterki, którą przewoźnik teraz sprawdza. Maszyna w piątek nie uda się w żaden rejs.

Hi,

Regardless of it arriving at 15:15, I doubt that is really enough time to enter it into service. Most aircraft are not delivered with everything in place ready to straight out on line. There is likely a lot of personalisation required including emergency equipment such as BCFs, PBEs etc...

If the airplane doesn't pass its FAA mandated "tests" both on the ground or inflight it doesn't deliver--the money guys aren't part of the equation, although there have been times they'd like to be.

Airplanes in their first few years of life continually come up with new and "interesting" issues--that's just a fact of life. Many people won't buy a new car model in its first year of production if its a drastic change from the previous years model--same thing.

It doesn't tell me that the car is not going to require major maintenance or repairs in the near future, or that the heating and airconditioning works. I don't think the planes aren't safe, that people's lives are being put at risk, Boeing wouldn't do that.

Not necessarily. We don't know how the aircraft are handed over and as another member pointed out, some carriers take delivery without seats fitted; notably, BA. I am pretty sure LOTs 787s are delivered with the full cabin installation however, that said, there are still likely other aspects not yet in place for instance, as mentioned, certain equipment, IFE content etc.

What could be wrong with an airplane that would make it not ready to deliver, yet would still be allowed to actually deliver (by Boeing, the airline, and the regulators)? The OEM can't make the airline take delivery if they don't want to, and they can't deliver even if the airline wants it if the regulator says, "No."

A new type is entering service. What's odd here isn't what's happening to the airplane, it's the level of reporting. Basically exactly the same thing happened with the A380 EIS. The 787 and the A380 are the first EIS's with major and ubiquitous media coverage.

In that case, all Boeing introductions have been run by "the Three Stooges". So far, the 787 hasn't done anything odd for a new type introduction. The exact nature of the bugs is unique, as it always is, but the fact of bugs is not. We just hear way more about them now than we did before.

It was mechanical problem. Fixed. I suspect some sort of material defect in the part of the landing gear, as the landing itself was nothing out of the ordinary (as reported by many LO DreamTour passengers, all landings were "smooth" - surely they would have noticed hard one).

SP-LRB is most likely something related to electrics/electronics, as the warning light went on during pre-flight check before planned trip to VIE. More than likely, something was done out of sequence due to the rush of the crew, as everyone was struggling to get SP-LRB to fly the Vienna evening round trip. The 737 was truly last minute substitution, it went out 2 hours late.

It is very wise of LOT to take their &*&s out of service until the electrical problems are sorted out. No one wants an inflight incident.

I notice that the only 787s flying around, according to Flightradar24, are the one's based in Japan. Have QR taken their 787s out of service too as a precaution?

It's usual for customer airline engineers to be at Boeing (or Airbus, etc) when taking first delivery of a plane that's new to the fleet, but it has much more to do with learning and familiarization than overseeing the manufacturer.

Exactly. There is no obligation for anyone to tell us anything, but you combine hard landing with going tech for gear problems, and you have to wonder. And that can include brake problems, because you could easily bounce while braking causing some strain on the brakes that may not be normal.

Which is NOT to say it is LOT's fault. Again, it could be Boeing's fault for having a tolerance too low under this condition that was never replicated during testing. If we see some sort of redesign of the brakes after this incident, that might be a clue.

It could also have been a fault in the flight control software that lead to the hard landing. But to just dismiss the accounts of a hard landing from those ON THE FLIGHT because other flights were smooth is ludicrous.

Maybe, but this can only be part of the problem.

It is certainly true that introducing any new aircraft into the fleet of an airline is complex. When it is a brand new aircraft type on top of that, the complexity is multiplied. A wise airline will always take a measured approach rather than diving right in.

In the case of NH & JL, they were both deeply involved with the 787 engineering effort with a large engineering staff in Everett for years while the 787 was being developed. Still, they each took a month after first 787 delivery before beginning revenue flights with their 787s. AI & ET have far less experience with the 787 and less understanding of the airplane, but have pushed the 787 into revenue service much faster. UA, LO & LA have the same amount of experience with the 787 as AI & ET, but have taken a more conservative approach to placing the aircraft into service.

Airline - Time from delivery to first revenue flight

UA.. 41 Days
JL.. 35 Days
LA.. 31 Days
NH.. 30 Days
LO.. 30 Days
AI... 13 Days
ET.. 1 Day

As a point of comparison, Malaysia took their first A380 in on May 27, 2012 and did not put it into revenue service until July 1 - 5 weeks later - for an airplane type which had its EIS 5 years ago.



When we flew ZA001 to WAW after the Paris Airshow in 2011, I was struck with just how small an operator LO is. I don't say this in a disparaging way toward LO, because I KNOW they are a quality operator. However, they do not have the same engineering and technical resources at their disposal as NH, JL or UA. With the same level of experience as UA, and fewer resources, LO has chosen to push the airplane into service faster. In a relative sense, they are pushing the 787 harder than UA. This may be a part of the reason for their difficulty.

On the other hand, some of the issues LO is rumored to have faced (defective landing gear component, door seal leakage, etc) would be workmanship and quality problems, and no amount of knowledge about the airplane or prep in advance of placing it into service would help mitigate these types of problems. If true, these issues can't point back to LO, even if there were a few rough landings.

Edit: Clarified last statement.

With the introduction of B787 aircraft, the old B767 were supposed to be phased out.

There were no scheduled flights on B767 beyond North American and Asian destinations.


So if they're not going to continue some of these short-haul flights, where are all their 787s going to go? They ordered 8, but they cut EWR, KRK, and RZE so it would seem like a few of them could be sitting around quite a bit. Any chance of getting some new/restored service to North America or are all the new routes going to be to Asia?

Yes, although it relies on the flight crew to notify maintenance of a potential hard landing. Maintenance then pulls the landing data, which includes a capture of acceleration on all three axes (both directional and rotational) at touchdown. There's a table in the AMM that specifies what action should be taken based on the values.

Indeed that seems the case. Gazeta Wyborcza has an article on it (sorry in Polish). According to the article, this time there was no problem with the plane, rather bad weather conditions due to fog. The flight circled over Vienna a number of times and then returned to Warsaw. The passengers after returning to Warsaw switched planes and are waiting (at the time the article was written) for improvements to the weather in Vienna.

By the time of departure, the info was that conditions at VIE would be within CAT I RVR of 550m and that the weather will improve...nature is tricky.

The choice of returning to WAW instead of a diversion, was that all logical alternatives had similar or even worse weather, or not ready to service the 787, besides at WAW the 787 has a whole on-site support team, I think during these "test runs" they always plan to be able to return to WAW in any case unless it is an emergency.

Pretty decent, I suspect. As per the list of flights that was made available here:
LOT's 787 Dreamliner Flights Around Europe (by kamilinlondon Oct 21 2012 in Civil Aviation)
there will be no more than two 787 rotations on that day; WAW-BRU-WAW and WAW-FRA-WAW. The entire promotional flight schedule seems to be designed for one aircraft, and with generous buffers on top, so SP-LRB must be busy doing other things while SP-LRA is used for the promo flights. Unless both go tech, LRB is probably going to be available as a backup - just the way it was used on e.g. WAW-HAJ-WAW on the 23rd.

According to LOT spokesman, the pilots went through the checklist, consulted with Boeing, and were able to address the problem and return to WAW (empty, no pax), leaving FRA at Noon.

By the time I arrived at the gate -LRB was already there and looked set to go but we were still delayed by over an hour due to "operational reasons" and a lot of attention was being paid to the nose gear by ground staff but no other reason was given until boarding suddenly started.

In return I flew on SP-LRB on the return section HAJ to WAW and with a very light passenger load (LF between 25 and 30 %) and noticed that the aircraft taxied very (!) slowly. Especially at WAW it was slower than walking speed.

Today's rotation to BRU and back currently is being carried out by SP-LRA (passing south of Magdeburg at the time of writing) operating on time.

Is it as quiet as the film clips made seem to give the feeling of? Even the 748i seems quiet compared to the 744. As more planes will be twins it is a positive if engines get quieter.

I was sitting in seat 28J which is the window seat in the second last row on SP-LRB.
Here is my perception:
Engine noise was negligible in cruise; during take off and climb it was audible but nothing to be concerned of, taking into account that the engines likely were derated for that take off with a very light load. Still the take off roll was very short.

More noise is coming from the air rushing along the fuselage - and for a new design, I was not too impressed by the noise levels I experienced.
Also ventilation makes noticeable noise as did some kind of pump (or similar) that was operating until a good way throughout climb.

Granted, my last experiences with A330 / A340 have been in the front of the cabin, but I found the back of the B788 noticeably more noisy than the front of the said Airbii. And I am only referring to technical noise, not created by humans.

Also I found the electronic window shading operating very slowly. It was that slow that I first thought that it was inop. A full darkening took like 60 seconds or so (based feeling, no stop watched), the same is true for becoming fully translucent.

Center hydraulic pumps. There are two and they're inside the wing-body fairing under your feet. Prior to takeoff they both go to high speed to provide sufficient hydraulic power for fail-safe gear and flap retraction. Once the airplane cleans up one shuts down and the other goes to low speed.

In general, the front is always quieter than the back. Most of the mechanical systems (i.e. the noisy ones) are in the wing/body fairing and the tail, and the air noise gets worse as you go back.

Also,what are my chances for the fifth of Jan BRU-WAW LO 236?

Glad to see your flight was operated by a 787, let us know how it went

Center hydraulic pumps.

That's this high-pitched sound? It ceases at 11:15.

Thanks for that explanation tdscanuck, now at least I know what was driving me crazy before. I found that high pitch noise extremely disturbing on my 787 flights and in fact was probably the only thing that disturbed, but totally ruined my cabin comfort experience at the beginning on my 787 trips... I remember on my first 787 flight on ANA I thought I will simply open the door and get out if I have to listen to that sound all through my trip.

Yepp...that is that annoying sound... However what I find interesting is that on the ANA 787s (and I yet have no other experience with 787s) this annoying sound started right after pushback and stopped as soon as the engines spooled up for takeoff...or at least when reaching a mid speed down the runway, but definitely before leaving the ground. I think this whining greatly disrupts the overall experience.

...by the way I will be on a joyride trip on the LOT 787 BUD-WAW on the 11th, and be back on it WAW-BUD on the 13th anyone else on the flight?

As this specific plane is no longer "technical" and the thread has run its course for all intents and purposes, it will be locked for further contributions. Any posts added after the lock will be removed for housekeeping purposes only.

Thanks and regards,
