WASHINGTON, Oct 21 (Reuters) - The U.S. Senate Commerce

Committee on Tuesday voted to approve aviation safety

legislation after a fatal January collision involving an

American Airlines ( AAL ) regional jet and an Army helicopter

that killed 67 people spurred calls for reform.

The bill requires aircraft operators to equip their fleets

with an advanced aircraft-tracking technology known as ADS-B by

the end of 2031 and other significant safety reforms, including

boosting oversight of mixed jet and helicopter traffic and

flight routes near commercial service airports. The Army Black

Hawk in the fatal crash was not using ADS-B at the time of the

crash.
