Boeing Co. has removed the executive in charge of the 747-8 jumbo jet program.

Already plagued by delays in its Dreamliner program, Mohammed Yahyavi has been removed as head of Boeing’s 747-8 jumbo jet program in Everett, Washington.

Oversight of the 747-8 program will now be taken on by Vice President Pat Shanahan who will be attempting to speed up the delivery program.

Although scheduled for delivery this year, Boeing has been forced to admit that delivery of the 747-8, like that of the Dreamliner, is likely to happen in 2011.

The 747-8 is a stretch version of Boeing’s iconic 747 jumbo jet.
