Manufacturer Serial Numbers (MSN) 322 through MSN 400
inclusive. Requirement: 1. Perform an inspection for signs of
heat damage of the wires, splices and related link wires in the
area of terminal block (TB152) in accordance of paragraph 3 of
Pilatus PC-12 Service Bulletin (SB) 30-009. 2. Perform a check of the wires and related link

[AWG]) are installed as specified in paragraph 3.B. of SB 30-0009
and Wiring Manual (WM) 30-40-00 and 30-40-10. 3. If any signs of heat damage or incorrect wiring
are found during the Requirements 1 and 2 inspections, replace them
in accordance with SB 30-009. Note: FOCA Switzerland AD HB-2005-079
refers. Compliance: For Requirements 1 and 2 - Within the
next 10 hours time-in-service but not later than three calendar
months after the effective date of this Directive. For Requirement
3 - Before further flight. This Airworthiness Directive becomes
effective on 18 February 2005. Background: The Swiss Federal Office
for Civil Aviation (FOCA) has advised of a report of a
Co-Pilot’s windshield de-ice system failure. The cause of the
defect was found in an overheating of the return wire from the
windshield heating system. Investigation revealed that the
installation of the wiring in question was not in accordance with
the specifications given in the applicable wiring diagrams
(incorrect AWG). This could result in heat damage of the wiring and
as a consequence, electrical arcing or possible fire in the
overhead panel in the flight-compartment.
