[Docket No. FAA-2009-0810; Notice No. 09-10]
RIN 2120-AJ21
Design Maneuvering Speed Limitation Statement
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The Federal Aviation Administration proposes to amend the
airworthiness standards applicable to transport category airplanes to
clarify that flying at or below the design maneuvering speed does not
allow a pilot to make multiple large control inputs in one airplane
axis or single full control inputs in more than one airplane axis at a
time without endangering the airplane's structure. This proposed
regulation is the result of an accident investigation and responds to a
National Transportation Safety Board recommendation. The results of the
accident investigation indicate that many pilots might have a general
misunderstanding of what the design maneuvering speed (VA)
is and the extent of structural protection that exists when an airplane
is operated at speeds below its VA. This action is being
taken to prevent this misunderstanding from causing or contributing to
a future accident.
