WASHINGTON, March 11 (Reuters) - National Transportation Safety Board Chair Jennifer Homendy will testify at a March 27 Senate Commerce hearing on the mid-air collision of an Army Black Hawk helicopter and American Airlines AAL.O regional jet that killed 67 people, the panel said.

The panel's aviation subcommittee will examine preliminary findings of the January 29 crash. The committee has also invited the acting head of the Federal Aviation Administration, Chris Rocheleau, and Brigadier General Matthew Braman, who is director of Army Aviation.
