NTSB's 5 Most Wanted
Aviation Safety Improvements in 2016

Today 01-14-2016] The National Transportation Safety Board (NTSB) has released
its 2016 Most Wanted list of transportation safety improvements. Throughout the
list, the agency focused on how the use of technology can be increased, reduced
or used in different ways than it currently is being used to improve different
areas of transportation.

Here are
the five items from this year's list that NTSB wants to see improved in
aviation.
1. Cockpit Image Recorders
Aviation
safety investigators for NTSB as well as other agencies and manufacturers
extensively use Flight Data Recorders (FDRs) in flight accident investigations
to review exactly what happened at what time during what phase of flight to
what components or systems on the aircraft. According to Eurocontrol's
"Skybrary" aviation technical information source, the International
Civil Aviation Organization (ICAO) Annex 6 requires all aircraft with a maximum
certificated takeoff weight of more than 12,500 pounds to be equipped with an
FDR.
The 2016
Most Wanted List from NTSB goes a step beyond data recording and recommends
cockpit image recording.
"We
also suggest equipping smaller turbine-powered aircraft with image-recording
devices and transport-category and Helicopter Emergency Medical Service
rotorcraft with flight recorders. The NTSB encourages operators across the
industry to routinely review recorded information in structured programs,"
NTSB said.
NTSB has
recommended cockpit image recorders several times in past safety
recommendations to the FAA,
including once in 2000 and in 2015 to prevent future occurrences similar
to Malaysia Airlines Flight MH370, which
required a year of searching to locate. Pilot unions have repeatedly opposed
these recommendations, arguing that the images or footage could be misused by
investigators, prosecutors and media.
2. Prevent Loss of Control in Flight
In 2016
NTSB is also continuing its call for more effort to prevent loss of control in
flight accidents by General Aviation (GA) pilots. The agency reported that
between 2008 and 104, 47 percent of fixed-wing GA accidents involved pilots
losing control of the aircraft that resulted in 1,210 fatalities.
NTSB mentions
approach to landing, maneuvering, and initial climb as the most recurring
phases for loss-of-control accidents. The agency also specifically notes
"pilot inattention due to workload, distractions or complacency, and a
lack of understanding how a stall actually relates to exceeding a wing’s
critical angle of attack (AOA)" as common causes of loss of control
accidents.
Additionally,
NTSB is recommending GA owners and pilots install AOA indictors to help prevent
accidents during critical and high-workload phases of flight.
3. Fatigue Related Accidents
NTSB is
recommending that the FAA help
commercial airlines and air traffic controllers recognize individuals at
high-risk of human fatigue. In its recommendation on reducing fatigue-related
accidents, the agency cited fatigue as an issue in nearly 20 percent of 182
major investigations completed between Jan. 1, 2001 and Dec. 31, 2012.
"Companies
must establish fatigue risk management programs and then continually monitor
their success to reduce fatigue-related risks for personnel performing
safety-critical tasks," said NTSB.
4. Reducing Distractions
NTSB
listed disconnecting from "deadly distractions" such as text
messaging or surfing the web on a smart phone or tablet as one of its most
wanted safety improvements for aviation and all modes of transpiration in
2016.
"For
decades, aviation has recognized the need for 'sterile cockpit' procedures
that restrict activities and conversations to the task at hand. But all
modes of transportation need to rise to today’s distraction challenges. That’s
why, in December 2012, we called for a driver ban for all PEDs. We have issued
similar recommendations for aviation, marine, and rail.
FAA
actually already largely addressed this safety concern in April 2014 issuing a
final rule prohibiting flight crew me members in Part 121 operations from using
a personal wireless communications device such as a laptop or smart phone for
personal use while the aircraft is being operated.
5. Medical Fitness
NTSB's
final aviation related most wanted safety improvement in 2016 is to create a
comprehensive medical certification system for safety-critical transportation
operators, including pilots. While the agency mentions that the "aviation
medical certification system may be the most robust," pilots have also
been increasingly testing positive for over the counter sedating
medications.
NTSB
also specifically recommends that the FAA and other transportation regulatory
agencies provide guidance for medical providers that should be used when the
provider believes a medical condition would disqualify an individual for duty.
Certain provisions within the recommendation are similar to a new rules
introduced by the European Aviation Safety Agency (EASA) requiring pilots to be
screened for mental illness after accident investigators discovered last year
that the pilot responsible for the Germanwings crash was
undergoing medical treatment for depression.
