(Reuters) - U.S. supplier Spirit AeroSystems ( SPR ) will implement a 21-day furlough for approximately 700 employees working on the 767 and 777 programs, effective Oct. 28, the company said on Wednesday.

The financial pressures may require the company to implement layoffs and additional furloughs, Spirit added.

The company also released results on Wednesday, reporting third-quarter revenue of $1.47 billion and a loss of $4.07 per share.
