NTSB UNDERTAKES COMPREHENSIVE STUDY OF EXPERIMENTAL AMATEUR-
BUILT (E-AB) AIRCRAFT SAFETY
Seeks input from E-AB pilots and builders
************************************************************
WASHINGTON - The National Transportation Safety Board has
launched a study of accidents involving E-AB (sometimes
called homebuilt) aircraft in order to evaluate the safety
of this growing and innovative segment of general aviation.
The Experimental Aircraft Association (EAA) will support the
project by hosting a web-based survey for E-AB owners of the
aircraft; their survey findings will be shared with the
NTSB.
“Going all the way back to the Wright brothers, amateur
aircraft builders have played a crucial and inspirational
role in leading the way towards greater achievements in
manned flight,” said NTSB Chairman Deborah A.P. Hersman. “We
are pleased to be working with EAA towards the shared goal
of improving safety in this particularly innovative sector
of general aviation.”
Of the approximately 224,000 general aviation (GA) aircraft
in the U.S., about 33,000 of them are classified as E-AB.
This includes a wide variety of aircraft, which can be built
from a prefabricated kit, existing plans, or a builder’s
unique design. Unfortunately, this group of aircraft has,
for several years, experienced accident rates greater than
those of other comparable segments of GA. The NTSB and EAA
are collaborating to identify how to improve that record.
The study will look at a range of issue areas, including
builder assistance programs; transition training for pilot-
builders of E-ABs; flight test and certification
requirements; maintenance of E-AB aircraft; and the
performance and failures of systems, structures, and power
plants.
“Earlier studies have looked at isolated E-AB safety issues,
but this is the first study to comprehensively examine both
the building and piloting of these unique aircraft,” said
Joseph M. Kolly, Director of the NTSB Office of Research and
Engineering. “And the direct input from E-AB owners and
others involved in the design and day-to-day operations of
these aircraft will be of enormous value in understanding
all of the aspects that play a role in the safety of
experimental flight operations.”
The EAA will be collecting survey data this summer.
Operators, builders, and owners of E-AB aircraft who are
interested in participating in the survey should go to
The completed safety study is expected to be published by
the fall of 2012.
