FARNBOROUGH, July 23 (Reuters) - A top Boeing ( BA )

supply chain executive on Tuesday said suppliers and airlines

have the right to be skeptical about company jet output

forecasts, following a recent decline in the planemaker's

production.

"It's a fair sentiment on the part of the supply base and

the airlines to say that we failed our commitments to them in

terms of the timeline," Ihssane Mounir, SVP global supply chain

and fabrication for Boeing ( BA ), told a discussion panel with other

executives at the Farnborough Airshow.

The U.S. planemaker, which has plans to increase output of

its strong-selling 737 MAX, has reduced production significantly

this year after coming under legal and regulatory scrutiny

following a Jan. 5 panel blowout on a near-new 737 MAX 9.
