The NTSB has issued four safety recommendations and reiterated one older recommendation to prevent runway excursion accidents following tailwind landings.
On December 22, 2009, American Airlines flight 331, a Boeing 737-800, N977AN, ran off the departure end of runway 12 after landing at Kingston-Norman Manley International Airport (KIN), Jamaica. The aircraft landed approximately 4,000 feet down the 8,911-foot-long, wet runway with a 14-knot tailwind component and was unable to stop on the remaining runway length. After running off the runway end, it went through a fence, across a road, and came to a stop on the sand dunes and rocks above the waterline of the Caribbean Sea adjacent to the road. No fatalities or postcrash fire occurred.
The investigation, being conducted by the Jamaica CAA, is still ongoing. The NTSB, being part of the investigation, decided to issue the following recommendations to the Federal Aviation Administration (FAA):
Require principal operations inspectors to review flight crew training programs and manuals to ensure training in tailwind landings is (1) provided during initial and recurrent simulator training; (2) to the extent possible, conducted at the maximum tailwind component certified for the aircraft on which pilots are being trained; and (3) conducted with an emphasis on the importance of landing within the touchdown zone, being prepared to execute a go-around, with either pilot calling for it if at any point landing within the touchdown zone becomes unfeasible, and the related benefits of using maximum flap extension in tailwind conditions. (A-11-92)
Revise Advisory Circular 91-79, “Runway Overrun Prevention,” to include a discussion of the risks associated with tailwind landings, including tailwind landings on wet or contaminated runways as related to runway overrun prevention. (A-11-93)
Once Advisory Circular 91-79, “Runway Overrun Prevention,” has been revised, require principal operations inspectors to review airline training programs and manuals to ensure they incorporate the revised guidelines concerning tailwind landings. (A-11-94)
Require principal operations inspectors to ensure that the information contained in Safety Alert for Operators 06012 is disseminated to 14 Code of Federal Regulations Part 121, 135, and 91 subpart K instructors, check airmen, and aircrew program designees and they make pilots aware of this guidance during recurrent training. (A-11-95)
The National Transportation Safety Board also reiterates the following recommendation to the Federal Aviation Administration and reclassifies it “Open—Unacceptable Response”:
Require all 14 Code of Federal Regulations Part 121, 135, and 91 subpart K operators to accomplish arrival landing distance assessments before every landing based on a standardized methodology involving approved performance data, actual arrival conditions, a means of correlating the airplane’s braking ability with runway surface conditions using the most conservative interpretation available, and including a minimum safety margin of 15 percent. (A-07-61)
This recommendation, A-07-61, was issued following the December 2005 runway excursion accident involving a Boeing 737-700 at Chicago-Midaway Airport.
