Boeing has stuck closely to it round-the-clock 24-hour testing schedule for ZA001, which began on Friday evening.
Video captured on Monday afternoon (June 1st) of smoke coming from Dreamliner One's engines was reported by the Seattle Times to be a "gauntlet relight test." The test, which appears to have been a part of Block Six testing, has flight test teams interrupting and "aborting the engine start-up just shy of fuel ignition," citing a Boeing source familiar with the situation. The smoke, the paper added, was un-ignited evaporating fuel.
According to Boeing, "this was the expected result for the test condition."
Aviation Week detailed the eighteen testing blocks (1-7, 8-12 & 13-18) that ZA001 has/will run through over the last week.
- Block Six - More test "flights" for the propulsion and electrical systems. Pre-dawn June 1
- Block Seven & Eight - Electrical, ECS and hydraulics. 2nd half of June 1
- Block Nine - Hydraulics and Flight Control Systems. Early June 2
- Block Ten & Eleven - Flight controls & Environmental Control Systems tests Late June 2
- Block Twelve - Re-run of Common Core System testing. Overnight June 2
- Block Thirteen - Electrical systems testing. Pre-dawn June 3
- Block Fourteen - Environmental Control Systems testing. Morning June 3
- Block Fifteen - Common Core System tests. June 3
- Block Sixteen - Electrical systems tests. Early June 4
- Block Seventeen - Pilot 'conditioning' and preparations for flight. June 4
- Block Eighteen - Final CCS evaluations. Late June 4 into early June 5
Meanwhile, the center fuselage for ZA100, the first production 787, continues to be worked on at Global Aeronautica. Originally planned for delivery late last month, Boeing opted to hold the center fuselage in Charleston, SC to eliminate any traveled work and limit additional out of sequence assembly in Everett to match the readiness of other structural sections. The center fuselage is the final major structural assembly awaiting delivery to Everett, after the vertical tail was shipped from Frederickson, WA last week.
According to several sources, the forward fuselage for ZA100, which was delivered on May 26 from Spirit Aerosystems in Wichita, arrived at 100% completion of assembly.
