Report Follows Runway Excursion At Jackson Hole, WY, In 2010

The NTSB has adopted its report concerning the December 29, 2010 incident in Jackson Hole, WY, in which an American Airlines Boeing 757 (similar airplane pictured in file photo) ran off the departure end of the runway and came to a stop in deep snow after landing.

In a letter to acting FAA administrator Michael Huerta, NTSB chair Deborah A.P. Hersman said the board was making the following recommendations:

• Require all operators of existing speedbrake-equipped transport-category airplanes to develop and incorporate training to specifically address recognition of a situation in which the speedbrakes do not deploy as expected after landing.
• Require all newly type-certificated 14 Code of Federal Regulations Part 25 airplanes to have a clearly distinguishable and intelligible alert that warns pilots when the speedbrakes have not deployed during the landing roll.
• Require Boeing to establish guidance for pilots of all relevant airplanes to follow when an unintended thrust reverser lockout occurs and to provide that guidance to all operators of those airplanes.

Hersman said that the recommendations are derived from the board's investigation and are consistent with both the evidence found and the subsequent analysis. Vice Chairman Christopher Hart, and board members Robert Sumwald and Mark Rosekind concurred with the recommendations.
