Appendix 1
COLD WEATHER OPERATIONS
The airplane must be equipped with the following equipment when
operating at an airport in the ground icing conditions defined
under `Visual/Tactile Check' in the LIMITATIONS section: 1. Pilot
assist handle, Cessna P/N SK208-146-2 (or FAA-approved equivalent
part
number)
Appendix 2
Lower main landing gear leading edge deice boots
Cargo pod nosecap deice boot
Appendix 3
The following additional equipment is not required for flight
into icing conditions as defined by FAR 25, but may be installed on
early serial airplanes by using optional accessory Kit AK208-6. On
later serial airplanes, this equipment may be included with the
flight into known icing package. If installed, this equipment must
be fully operational.

Background:
This AD requires the installation of pilot assist handle and
de-icing boots on the cargo pod and landing gear fairings and make
changes to the POH and AFM. This AD results from reports of several
accidents involving the affected airplanes during operations in
flight and in ground icing conditions. This AD is intended to
provide a safe method to detect ice, snow, frost, or slush adhering
to the upper wing (a critical surface) prior to takeoff; and to
reduce drag in-flight by shedding ice on the cargo pod and landing
gear fairings. Ice adhering to the upper wing surface, cargo pod,
or landing gear fairings could result in a reduction in aeroplane
performance with the consequences that the aeroplane cannot perform
a safe takeoff or climb. This amendment changes the applicability
of the aeroplane listed in requirements 3 and 4, and changes the
compliance period for requirement 2. These changes are made
following a correction to the referenced FAA AD.
The original issue of this AD became effective 11 May 2006.
