WASHINGTON, Feb 11 (Reuters) - The Federal Aviation

Administration said two runways at Reagan Washington National

Airport have reopened after a fatal Jan. 29 collision killed 67

people and the agency is boosting the maximum hourly flight

arrival rate.

Reuters first reported last week the FAA had reduced the

maximum arrival rate from 28 to 26 aircraft per hour after a

U.S. Army helicopter collided with an American Airlines ( AAL )

regional jet, citing safety risks and the two closed smaller

runways. The FAA noted Tuesday the regular maximum hourly

arrival rate is 32 planes per hour at Reagan and helicopter

restrictions imposed after the incident remain in effect.
