NTSB eyes lack of landing tool in air crashJuly 7, 2013 @ 8:44 am
WASHINGTON (AP) - An aviation safety official says accident investigators are looking into what role the shutdown of a key navigational aid may have played in the San Francisco plane crash.
National Transportation Safety Board Chairman Deborah Hersman says the glide slope _ a ground-based aid that helps pilots stay on course while landing _ had been shut down since June.
She says pilots were sent a notice warning that the glide slope wasn't available.
Hersman tells CBS' "Face the Nation" that there were many other navigation tools available to help pilots land. She says investigators will be "taking a look at it all."
The Asiana Airlines plane crashed as it was about to land Saturday, breaking off its tail and catching fire.
