Foreword
ForewordForeword
Foreword
HB-Y T is a Van’s aircraft (www.vansaircraft.com) RV-7A all-
metal, low wing, two seat, high performance aircraft. It was
built by A. Lichtensteiger and B. Daenzer from a Van’s
quickbuild kit during the years 2005 until 2010 under the
supervision of EAS (www.experimental.ch).
An extensive documentation of the building process can be
found at www.flyvans.com in the builder’s log.

This aircraft is classified as “experimental”. Hence certain
design features may deviate from the typical “spam can”
certified production aircraft. Also, flight characteristics such as
high roll rate and light control forces can be more
demanding to the pilots’ skill.
This aircraft has been built by the builders to the best of their
knowledge and quality of craftsmanship. Nonetheless,
operating this aircraft is at the sole risk of the pilot.

procedure leads to an immediate or important degradation
of the flight safety
CAUTION
means that the non
-
observation of the corresponding
procedure leads to a minor or to a more or less long term
degradation of the flight safety.
NOTE
draws the attention to any special item not dire
ctly related to
safety but which is important or unusual.
