WICHITA, Kan. (AP) — Bombardier says it is “pausing” its Learjet 85 business jet program and laying off about 1,000 workers in Kansas and Mexico.

Wichita is taking the brunt of the cutbacks with 620 jobs affected. The remaining job losses are in Queretaro, Mexico.

The Montreal-based company said Thursday the cuts are due to weak demand for the plane. The company cited the continued weakness of the light aircraft market since the economic downturn.

Bombardier also said it will take a $1.4 billion pre-tax special charge in the fourth quarter of 2014.

Pierre Beaudoin, the company’s president and chief executive officer, says Bombardier constantly monitors its product strategy and development priorities. He says given the weakness of the market, the company made the difficult decision to pause the Learjet 85 program.
