Boeing may assemble the re-engined 737 Max in the same facility as it builds the 737 NG family of aircraft in Renton, Washington.
Beverly Wyse, 737 programme vice-president and general manager, said a potential third line for the Max would be placed in Renton with the two existing lines by relocating engine, empennage and line work staging areas positioned between Line 1 and a mezzanine that runs the length of the building.
Commercial production at Renton is split between two lines in the 4-481 building. Line 1, the wider of the two lines, would likely play host to Line 3 for the 737 Max.
With a third line capable of 21 aircraft per month, Wyse said that, over time, 737 production rates could climb to 60 aircraft per month, including the 737 Max.
The relocated functions would be moved elsewhere in building or nearby. Eventually, 737 Max production would overtake the two 737 NG lines as building accelerates, though concurrent production of each family could eventually take place on each line.
The Max line, like the other two, would have a potential capacity of 21 aircraft per month, and would start as a dedicated final assembly line for the re-engined aircraft, due for first delivery in the fourth quarter of 2017.
Following the selection of Renton for 737 Max final assembly, many speculated Boeing would either build a third line in the so-called “saw-tooth” building (named for its jagged roofline) where the P-8A Poseidon, a heavily modified 737-800 for military use, is assembled.
A third 737 line would have probably have shared commercial production with the P-8A, or Boeing may have shifted the P-8 final assembly to Boeing Field in Seattle.
It will be one to two years before Boeing makes a final decision on exactly where at the Renton plant the 737 Max will be assembled. Both Wyse and a union official said building the 737 Max alongside the 737 NG seems most likely.
Wyse’s comments came during an informal press conference following a celebration at the Renton factory of the 737 production advancing from 31.5 to 35 aircraft per month, a record for the programme.
737 production rates will rise to 38 per month in 2013 and 42 per month in 2014.
Boeing delivers first 737 under new 35 per month rate
Boeing delivered today the first 737 aircraft produced at the new rate of 35 aircraft a month to aircraft lessor AWAS, marking the highest production rate ever achieved for the narrowbody programme.
The airframer plans to grow the rate to 38 a month in the second quarter of 2013 and to 42 in the first half of 2014. Beverly Wyse, VP and general manager of the 737 programme, indicated to Boeing employees that the rate could go up to 60 in the future. However, she later told FlightglobalPro that this was not a definitive announcement of Boeing policy and remains only a prospect based on market demand.
AWAS’ new 737 — the 35th aircraft built on the new rate schedule — will be leased to Norwegian Air Shuttle, said Boeing.
Production rates for the 737 have increased more than 150% since 2003, Wyse said. She noted that the aircraft received by AWAS was the smoothest of any rate ramp-ups, encountering only three shortages and eight instances in which work was not completed in position.
Wyse gave credit to Boeing’s labour union, the International Association of Machinists and Aerospace Workers (IAM), for its role in ensuring the smooth transition to the higher rate. Late last year, Boeing and the union agreed on a new four-year contract extension, following months of tumultuous relations between the two parties.
“This success could not be done without the partnering of IAM and SPEEA,” said Wyse, referring to the Society of Professional Engineering Employees in Aerospace, which represents Boeing’s engineers. “The new partnership with IAM means more successes ahead.”
SPEEA’s contract with Boeing becomes amendable in September, with negotiations to begin this year.
Wyse noted that there is a forecasted need for more than 23,000 single-aisle airplanes in the next 20 years. She predicted Boeing will capture half of this market.
Well with the NG production rate at about 42/month by the time the MAX enters production, a 3rd line is the only way to go. I don’t know if moving the P-8 production to Seattle makes any sense or is even needed. At best worlwide sales of the P-8 will be 200-300 airplanes as the various countries P-3s come up for replacement. I do see a possibility of a P-8MAX (call it the P-8B for now), and that could increase worldwide sales.
Boeing is envisaging to jack up production for a host of obvious reasons, clearly to reduce it’s order backlog, it also assists to recover Boeings declining share of single aisle maket, the restoration of pride also raises it’s head here with an attempt to recover the production lead lost for nearly a decade to EADS
Airbus starts 2012 with a monthly single aisle production of forty two, with an internal additional target of forty four per month being acheived by end of 2012
Investing in more production infrastructure to go beyond the above production figures, would potentially offer a short term gain on balance sheets, but likely realise a longer term loss.
I would think that the 3rd line needs to be a new building, get it up and running with the max. I would suspect that it would take nearly a year from 1st plane to get to say 20 per month. Then, one of the existing lines would need to go dark for a period (say 2 to 3 months) to convert to the max. A few years later, the 3rd line would stop production of the current 737. Would it change over – only if there is sufficient demand then for more than 35 to 40 per month.
My bet is that line #3 is going to be set up next to line #1 in the area where currently some pre-assembly is done. Easier to move the latter elswhere than to move the P-8 line.
