Memorandum by Boeing Commercial Airplane
Group (AS 24)
The letter dated 29 January 1999 to J C LongridgeBoeing
has been forwarded to me for response. I am the Boeing executive
responsible for technical activities involving our products in
Europe, including aviation safety matters.
The Boeing Company very much appreciates the
opportunity to present its views on commercial aviation system
safety. The following is provided as response in preparation for
your inquiry (our response is limited to commercial aviation).
What safety lessons can be learned after 19 years
of airline deregulation in the United States and five years of
airline deregulation in the United States and five years of European
deregulation, and what specific safety issues may be raised by
the emergence of new low cost airlines
There is no correlation between safety and deregulation
that resulted in numerous, so-called "low cost airlines".
In fact, the safety record as measured by accident rate has improved
in both the United States and Europe during this time period of
deregulation as shown in figures 1 and 2. This result points to
co-operation by airlines, flight/cabin/ground crews and their
associations, aviation authorities, and manufacturers. This situation
can only further improve with the recent focus on commercial aviation
safety in the US and Europe under the leadership of the US Federal
Aviation Administration (FAA) and Europe's Joint Aviation Authorities
(JAA). These activities are known as CASTCommercial Aviation
Safety Team (US, EuropeJSSI, and globalICAO and
IATA as shown in figure 3) and JSSIJoint Safety Strategy
Initiative (Europeas shown in figure 4.) From a total global
perspective, ICAO is developing the Global Aviation Safety Plan
which will link up the CAST and JSSI safety enhancing proposal
with the remainder of the world as shown in figure 5. The UK Civil
Aviation Authorities, UK operators/airlines, manufacturers and
pilots organisations are active participants in these safety initiatives.
The improvement in accident rate in the US,
Europe and Asia is countered by increases in accident rate in
Latin America and Africa such that the worldwide rate has remained
almost constant over the past 15 years or so.
What have been the trends in aviation accidents
and reportable incidents (a) in the United Kingdom and (b) worldwide,
over the last 10 years, both for commercial aircraft and general
users, including gliders
The data in figure 6 shows that while the worldwide
accident rate has remained almost constant over the past 15 or
so years, there is an increase in the number of accidents worldwide
as the number of departures continues to grow. With projections
that traffic will more than double in the coming years, this potential
growth of the number of accidents will continue unless something
new occurs to lower the worldwide accident rate.
Leadership in co-ordinating international implementation
of safety enhancements around the world and increased co-operation
on worldwide safety initiatives to help countries and regions
develop their oversight and infrastructure are the most important
actions that need to be taken.
What can be learnt from recent high-profile accidents,
and what has been the response of the relevant United Kingdom
and European authorities; to consider concerns raised by these
incidents, such as insulation used in transport aircraft wiring,
and other current concerns, and their potential impact on perceived
and actual passenger safety
As with any accident, the safety investigating
authority in the country where the accident occurred is responsible
for investigation and recommendation of preventive and corrective
action(s). The co-operation with other countries is of utmost
importance-particularly with the country of manufacture and country
of the aircraft's operating certificate. In the case of the recent
Swiss Air MD-11 off the coast of Nova Scotia this has been the
case. Despite the fact that the cause of the accident has not
been officially determined, several actions have been taken (e.g.,
inspection of wiring) to ensure the high level of safety is maintained.
What other safety critical issues face the aviation
industry, such as training, congestion, maintenance, and pilot
retirement
In Boeing's view there are no safety critical
issues because of the organised manner in which the aviation safety
system is being managed, i.e., a very co-operative, highly-respected
responsibility.
However, the three highest categories of accidents
continue even though intervention measures are available for implementation:
Controlled Flight into Terrain.
Figure 7 shows the interventions that are available
to address major factors of worldwide, recurring accidents.
There are several significant challenges that
face the system as the commercial aviation system continues to
grow. An example is congestion. However, using the case of congestion,
those responsible understand the need to impose restrictions on
growth unless mechanisms are put in place to deal with the growthsuch
as new technology systems for Air Traffic Management.
The adequacy of the current United Kingdom safety
oversight mechanism for the UK as vested with the Civil Aviation
Authority
It is our view that the CAA is one of the premier
aviation authorities in the world and performs its safety responsibilities
as both a regulator, with enforcement powers, and partner in the
aviation community (nationally and globally) with a very high
level of performance and professionalism. Numerous examples could
be cited. Just to name a few:
Recent UK accident studies (CAP 513),
including the latest on cargo operations.
Leadership role in JSSI.
Leadership and sponsor of International
Federation of Airworthiness (e.g., Human factors video/training
tool).
Again, the Boeing Company appreciates the opportunity
to provide inputs to the sub-committee. It is hoped that the above
responses will be helpful and contribute to your inquiry.
