Consider this a bit of catch up over the last several weeks on 747-8 progress. I wanted to bring you the latest on what’s going on with the first 747-8 Freighter – RC501 – coming together in Everett right now.
When the first stub join was completed, the wings were “flown” from the join position to the seal on the afternoon of June 7th. The crane, actually two cranes, that lifted the wings represented a record for Boeing after more than 40 years of 747 production. According to one source, the two cranes lifted 149,300 lbs. before placing the wings into the seal area.
Eleven days later, Boeing had the second set of wings in the stub join area. Which brings us to last week when the bonnet Section 44 was lowered into position over the center wing box on June 25th to begin the wing-to-body join.
Program sources also indicate that two of four General Electric GEnx-2Bengines have been delivered to final assembly. Final certification ofthe engine is expected to happen around October. Finally, the blended raked winglets will be added once the aircraft is moved to the slant position at the head of Building 40-22 because the wings would be wider than the join area!
