WASHINGTON, Oct 14 (Reuters) - The U.S. Senate Commerce

Committee is set to vote on October 21 on aviation safety

legislation after a fatal January crash between an American

Airlines ( AAL ) regional jet and an Army helicopter near Reagan

Washington National Airport killed 67 people.

The committee is set to take up legislation sponsored by

Senate Commerce Committee chair Ted Cruz and several other

senators to require the use of ADS-B, an advanced

aircraft-tracking technology, by military helicopters near

civilian planes and the use of ADS-B for all civilian aircraft.

The helicopter involved in the accident was not using ADS-B

at the time of the January collision.

Cruz is working with Senator Maria Cantwell in a bid to

reach bipartisan agreement on aviation safety legislation ahead

of the hearing, aides to both senators said.
