NTSB Safety Recommendations A-11-18 through -31

 

************************************************************

 

The National Transportation Safety Board makes the following recommendations to the Federal

Aviation Administration:

 

Require manufacturers of newly certificated and in-service turbine-powered aircraft to incorporate in

their Aircraft Flight Manuals a committed-to-stop point in the landing sequence (for example, in the

case of the Hawker Beechcraft 125-800A airplane, once lift dump is deployed) beyond which a go-

around should not be attempted. (A-11-18)

 

Require 14 Code of Federal Regulations Part 121, 135, and 91 subpart K operators and Part 142 training

schools to incorporate the information from the revised manufacturers' Aircraft Flight Manuals asked

for in Safety Recommendation A-11-18 into their manuals and training. (A-11-19)

 

Require 14 Code of Federal Regulations Part 135 and 91 subpart K operators to establish, and ensure

that their pilots adhere to, standard operating procedures. (A-11-20)

 

Require principal operations inspectors of 14 Code of Federal Regulations Part 135 and 91 subpart K

operators to ensure that pilots use the same checklists in operations that they used during training for

normal, abnormal, and emergency conditions. (A-11-21)

 

Require manufacturers and 14 Code of Federal Regulations Part 121, 135, and 91 subpart K operators

to design new, or revise existing, checklists to require pilots to clearly call out and respond with the

actual flap position, rather than just stating, "set" or "as required." (A-11-22)

 

Work with the National Weather Service to revise Advisory Circular 00-24B, "Thunderstorms," by

including explanations of the terms used to describe severe thunderstorms, such as "bow echo,"

"derecho," and "mesoscale convective system." (A-11-23)

 

Revise regulations and policies to permit appropriate use of prescription sleep medications by pilots

under medical supervision for insomnia. (A-11-24)

 

Require 14 Code of Federal Regulations Part 135 and 91 subpart K pilots to receive initial and recurrent

education and training on factors that create fatigue in flight operations, fatigue signs and symptoms,

and effective strategies to manage fatigue and performance during operations. (A-11-25)

 

Review the policy standards for all common sleep-related conditions, including insomnia, and revise

them in accordance with current scientific evidence to establish standards under which pilots can be

effectively treated for common sleep disorders while retaining their medical certification. (A-11-26)

 

Increase the education and training of physicians and pilots on common sleep disorders, including

insomnia, emphasizing the need for aeromedically appropriate evaluation, intervention, and

monitoring for sleep-related conditions. (A-11-27)

 

Actively pursue with aircraft and avionics manufacturers the development of technology to reduce or

prevent runway excursions and, once it becomes available, require that the technology be installed.

(A-11-28)

 

Inform operators of airplanes that have wet runway landing distance data based on the British Civil Air

Regulations Reference Wet Hard Surface or Advisory Material Joint 25X1591 that the data contained in

the Aircraft Flight Manuals (and/or performance supplemental materials) may underestimate the

landing distance required to land on wet, ungrooved runways and work with industry to provide

guidance to these operators on how to conduct landing distance assessments when landing on such

runways. (A-11-29)

 

Require that 14 Code of Federal Regulations Part 135 pilot-in-command line checks be conducted

independently from other required checks and be conducted on flights that truly represent typical

revenue operations, including a portion of cruise flight, to ensure that thorough and complete line

checks, during which pilots demonstrate their ability to manage weather information, checklist

execution, sterile cockpit adherence, and other variables that might affect revenue flights, are

conducted. (A-11-30)

 

Require 14 Code of Federal Regulations Part 121, 135, and 91 subpart K operators to ensure that terrain

avoidance warning system-equipped aircraft in their fleet have the current terrain database installed.

(A-11-31)
