No anche perche, essendo nate per i test, li stressano ben bene fino al limite, e in certi casi fino alla rottura. E sono fatte per questo: verificare se i progetti struttirali rispettano i criteri previsti dal progetto...

787 blows hot and cold


The 787 Dreamliner has begun a series of extreme-weather tests in Florida. A special hangar at the McKinley Climatic Laboratory at Eglin Air Force Base allows the airplane to experience heat as high as 115 degrees Fahrenheit (46 Celsius) and as low as minus 45 degrees Fahrenheit (minus 43 Celsius).
After the airplane is stabilized at either the hot or cold temperatures, flight test technicians will follow the Airplane Maintenance Manual to perform the steps required to prepare the airplane for flight release and operate under these conditions. Sensors and monitors will allow the test team to determine if all systems hardware and software operate as expected.
Cold-weather testing is being conducted first, with preliminary hot-weather testing to follow. Additional extreme-weather testing will be conducted later in the flight test program.
"We have Dreamliner customers who will operate the 787 in a wide variety of environments throughout the world," said Scott Fancher, vice president and general manager of the 787 program for Boeing Commercial Airplanes. "This testing is about ensuring that the airplane meets the expectations of our customers."
A crew of approximately 100 people traveled from Seattle to support the test operations on ZA003, the third 787 airplane to be built.
The McKinley Climatic Laboratory is the second remote testing location for the 787 Dreamliner. The second airplane in the fleet, ZA002, performed a variety of tests in Victorville, Calif., last month. The testing in Florida is expected to last nearly two weeks.

Boeing 787 Test Flights Halted

By Guy Norris - Los Angeles (Jun 25, 2010

Boeing is inspecting the horizontal stabilizers of all completed 787s for improperly installed shims that could potentially reduce the fatigue life of the unit if left uncorrected.

Boeing says the newly-discovered “workmanship issue” concerns small gaps found around the intersection of the stabilizer’s aft spar with the center box that forms the structural join between the two horizontal tails. The stabilizers, designed and manufactured by Alenia Aeronautica at its Foggia facility in Italy, are made up of two monolithic co-cured horizontal units and the center box.

The inspections are aimed at finding compressed shims where fasteners may have been over-torqued to complete assembly. This has the potential to alter load paths and load concentrations, thereby potentially reducing structural fatigue life. The company plans to perform rework and replacement where needed. If a shim — a ‘filler’ used to plug small gaps in completed structures — does require replacement, Boeing estimates the work will take up to eight days.

Flight tests have been suspended temporarily on ZA002 and ZA003, the only two 787 scheduled to fly on Thursday, June 24, while inspections continue. However “..the overall program schedule can accommodate the inspection process and the required rework without jeopardizing our delivery commitment,” says Boeing Commercial marketing vice president Randy Tinseth, commenting on his blog.

Boeing is reverting to ground tests for ZA003, which is now scheduled to undergo high intensity radiated field tests, while ZA002’s ground crew will take the opportunity of the inspection to perform regular maintenance. ZA001 is undergoing landing gear actuation tests prior to returning to flight tests with a new set of Trent 1000 engines. ZA004 continues its planned lay-up at Victorville, Calif., while having sensors installed for the coming load survey. Plans meanwhile continue for the start of flutter testing on ZA005, the first General Electric GEnx-1B powered 787.

Boeing starts 787 horizontal stabiliser inspections

By Jon Ostrower

Boeing has begun horizontal stabiliser inspections on two of its 787 flight test aircraft after it disclosed workmanship errors by supplier Alenia Aeronautica that could reduce the fatigue life of the parts.

ZA002 and ZA003, both Rolls-Royce powered 787 flight test aircraft will be inspected today at Boeing Field in Seattle and Pinal Airpark in Marana, Arizona, respectively. Neither aircraft will return to flight operations until the one to two-day inspections are complete, says Boeing.

Twenty-three of twenty-five horizontal stabilisers already shipped from Italy are installed on 787s, five of which are flying on flight test aircraft. ZA001, ZA004 and ZA005 are all currently in maintenance and instrumentation installation layup.



Scott Fancher, 787 programme vice president and general manager, declined to say which aircraft or how many have the horizontal stabiliser workmanship issues, saying only that he anticipates the rework to take eight days.

Additionally, an internal investigation has been launched as to how the workmanship issues escaped Boeing's notice during 25 shipsets delivered over three years from Alenia.

"It turns out [the issue] is fairly deeply imbedded in the assembly, so we're in the process of auditing the records associated with that to understand whether or not there's a systemic issue with the escape or whether it's a one off," says Fancher.

The rework focuses on two shims, or engineered gap fillers, in the aft part of the horizontal stabiliser and requires the re-torquing of 12 fasteners on either side of the structure, says Fancher.

Programme sources say the shims used to fill gaps in the horizontal stabiliser became compressed after fasteners were over-torqued as a means of pulling the surfaces together, introducing a "pre-load" condition reducing the long-term fatigue life of the structure.

Fancher concedes it is possible that some flight test operations will need to be re-sequenced due to the inspections or potential rework, but adds, "We think that's entirely manageable given our schedules and our status."

Fancher also adds that while the inspection or rework is being undertaken, ground testing can proceed.

Boeing anticipates 2,400h of flight testing and 3,100h of ground testing on its Rolls-Royce Trent 1000 powered test fleet to achieve certification and delivery to Japan's All Nippon Airways by year-end. To date, Boeing has accomplished nearly 1,060h of flying on its Trent 1000 fleet.

Third 787 returns home for additional inspections

By Jon Ostrower

Boeing's third 787 flight test aircraft has returned home to Seattle for additional inspections on its horizontal stabiliser, following weekend inspections.

ZA003, which has been based at Pinal Air Park in Marana, Arizona since 22 June for high-intensity radio frequency (HIRF) testing, returned home to Boeing Field in Seattle.

Programme sources indicate that following the aircraft's Sunday return to Boeing Field, ZA003 was set to continue horizontal stabilizer inspections which began 25 June, potentially indicating a discovery and further diagnosis of scope of the improperly installed shims and over-torqued fasteners.

Boeing declined to comment on ZA003's return from Marana, citing a policy not to discuss flight test operations.

ZA002 returned to flying on 27 June to conduct autopilot functional tests.

Programme sources also indicate that flight tests that were previously assigned to ZA003 late last week have been reassigned to ZA002 for testing on Monday. ZA005, the GEnx-1B-powered 787, is expected to make its second flight Monday as well.

The inspections were prompted following the discovery of workmanship issues that included improper installation of shims and fastener over-torquing in the horizontal stabiliser manufactured by Alenia Aeronautica in Foggia, Italy.

If left unaddressed the fasteners and shims, or engineered fillers, can create a long-term fatigue issue on the structure.

ZA003 is slated to be the first aircraft to make its international debut at the Farnborough air show in mid-July.

The aircraft is outfitted with a partial interior along with racks of instrumentation to test the aircraft's cabin systems.

Boeing aims to certify and deliver the 787 to Japan's All Nippon Airways by years end.

E' vero che Alenia non fa una bella figura pero' non bisogna pensare che le "porcate" le facciano solo gli italiani, ti assicuro che in 8 mesi da queste parti mi son resa conto che gli idioti non mancano nemmeno qua!
Comunque ritornando al progetto devo dire che essere stata presente alla festicciola per il primo volo del 787 motorizzato GE in GE e' stata una cosa priceless!
E poi mi son guadagnata un cioccolato Boeing, una bussola ed una moneta commemorativa (che c**o eh?!)

rileggendo il documento, però, mi sovviene un dubbio......
gli spessori ed i fermi tra le diverse sezioni, non dovrebbero essere inseriti in fase di assemblaggio finale? se questo fosse il caso, che c'entra Alenia? Se non ricordo male, l'aereo è assemblato ad Everett......

Boeing's 787 quality issues persist

By Jon Ostrower


As the supply chain came off a 24-manufacturing day hold in early June to allow supply partners to catch up on design changes and part shortages, workmanship issues on key structural areas of the aircraft again reared its head.

On 24 June Boeing had to disclose that it was forced to undertake inspections on the entire fleet of the horizontal stabilisers built by Alenia Aeronautica in Foggia, Italy, following the discovery of over-torqued fasteners and improperly installed shims in the rear spar.

Programme sources say the gaps, which the shims are intended to fill, range between 0.25cm and almost 0.5cm, and the ones used to fill gaps in the horizontal stabiliser became compressed after fasteners were over-torqued as a means of pulling the surfaces together, causing a "pre-load" condition that can undermine the fatigue life of the structure.


© Liz Matzelle

While Boeing maintains that the fleet had not been "grounded", the company decided not to fly each aircraft until it underwent two-day inspections before returning to flight-test operations.

The company insists that quality "escapes" such as the one found in the horizontal stabiliser is not uncommon during the early part of a programme, the episode was another in a series of workmanship issues that prompted an internal inquiry as to how 25 horizontal stabilisers could have been shipped to Everett over three years without notice.

Nearly a year ago, Boeing ordered a work stoppage at Alenia after wrinkles in the skin of the composite fuselage barrels exceeded tolerances.

"It turns out [the issue] is fairly deeply imbedded in the assembly," says Scott Fancher, vice-president and 787 programme general manager, referring to the issue with the horizontal stabiliser. "So we're in the process of auditing the records associated with that to understand whether or not there's a systemic issue with the escape or whether it's a one-off."

Boeing plans 787-9 horizontal stabiliser design change, explains -8 issues

By Jon Ostrower


With its final configuration for the 787-9 now set, Boeing is to incorporate significant changes in the stretch variant, which include a revised architecture for the carbonfibre horizontal stabiliser. The airframer has also provided more details on the stabiliser production issues that have required inspections of 787s already built.

The 787-9's two 3.1m (120in) fuselage extensions in the Alenia Aeronautica-built Section 46 and Kawasaki Heavy Industries-built Section 43 represent the most significant external change between the 787-8 and larger -9, although Boeing plans a host of internal changes for weight reduction and ease of assembly.

One such change, says Boeing's vice-president of supplier management Bob Noble, is a revised architecture for the horizontal stabiliser on the larger -9.

"As it happens we're going to make a change to the horizontal on the -9," he says, speaking at the Alenia's 787 fuselage manufacturing plant in Grottaglie, Italy. He adds that the revision was always planned for the larger variant, which is due to enter service with Air New Zealand in 2013.

An integral multispar box design will be employed on the 787-9 and will result in the spars and skins of the main stabiliser boxes being co-cured together, similar to the aircraft's composite fuselage and co-cured stringers, say programme sources.

The goal is to reduce the amount of parts and workmanship required to assemble the horizontal stabiliser following initial fabrication.

The change in the stabiliser, which is also driven by the different loads expected on the stretched variant, will also result in "a couple hundred pounds" of weight savings, compared with the 787-8.

The new stabiliser design is also being considered for incorporation on the 787-8, although Noble says that decision has not yet been made.

Speaking in Grottaglie, Boeing and its production partner Alenia avoided a formal "mea culpa" for the workmanship issues that have arisen on the horizontal stabiliser of early-build 787s. The airframer insists it is "positively certain" that the same defect will not occur again.

Alenia builds the 787's horizontal stabiliser at its Foggia plant in southern Italy and chief operating officer Daniele Romiti calls the production issue "normal in a manufacturing process".

Noble echoes the sentiment, saying "this is not at all related to the material system, it is not related to the quality system, it is just one of those things that happens during a manufacturing process".

Left unanswered is how the problem went unnoticed by both Boeing and Alenia for 25 shipsets, although Noble says "we know what it is. We're absolutely, positively certain we won't have that same defect again. We have put counter measures in place to assure ourselves of that."

Those countermeasures, says Noble, include a global examination of "all of our joins and make sure the similar thing can't happen anywhere else".

During inspection at its Everett, Washington facility, Boeing discovered shims used to fill gaps in the horizontal stabiliser became compressed after fasteners were over-torqued as a means of pulling the surfaces together, introducing a "pre-load" condition reducing the long-term fatigue life of the structure.

FARNBOROUGH: 787 touches down for UK debut

By David Kaminski-Morrow

Boeing's 787 twin-jet has touched down at the Farnborough Air Show, marking the aircraft's first appearance in the UK.

It headed in over north Wales, tracking south towards Oxford, and circled at around 9,000ft to the west of Farnborough before descending to conduct a flypast from the east.

The Rolls-Royce Trent 1000-powered aircraft, ZA003, then made a second approach and touched down, coming to a rapid stop on the runway.
