AD 2012-21-06 Airworthiness Directives; Hawker Beechcraft Corporation Airplanes
Makes named: hawker beechcraft. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Hawker Beechcraft Corporation Model C90GTi (King Air) airplanes, serial numbers LJ-1847, and LJ-1853 through LJ-1997, that are certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within the next 50 hours time-in-service after November 27, 2012 (the effective date of this AD) or within the next 6 calendar months after November 27, 2012 (the effective date of this AD), whichever occurs first, do the replacements specified below following the Accomplishment Instructions in Hawker Beechcraft Mandatory Service Bulletin No. SB 24-4050, dated November 2010: (1) Replace wire part number (P/N) CB41-J11-1 on the A124 fuel control panel assembly with a new wire P/N M22759/16-14-9. (2) Replace wire P/N J26-4-CB308 on the co-pilot primary flight display (PFD) and wire P/N J27-5-CB272 on the multifunction display (MFD) with a new wire P/N M22759/16-16-9.
Unsafe condition
This AD was prompted by reports of incorrect gauge wires used in the wiring bundles for the cockpit electrical power for backlighting and instrument panel components. We are issuing this AD to prevent failure of the wiring for the power to the airplane's cockpit backlighting and instrument panel components. Failure of the wiring for the airplane's cockpit backlighting and instrument panel components could cause smoke in the cockpit; loss of power to the multifunction display, the co-pilot's primary flight display, and cockpit lighting; and potential damage to surrounding wires and components.
Affected ADs
None.
