Hawker Beechcraft Corporation Airplanes
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.
We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model C90GTi (King Air) airplanes. This AD was prompted by reports of incorrect gauge wires used in certain wiring bundles for the cockpit electrical power for backlighting and instrument panel components. This AD requires replacing incorrect gauge wires in certain electrical power wiring bundles, inspecting associated wiring bundles and components for heat damage, and taking all necessary corrective actions. We are issuing this AD to correct the unsafe condition on these products.
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.
While doing the replacements required in paragraphs (g)(1) and (g)(2) of this AD at the compliance time specified in paragraph (g) of this AD, visually inspect the associated wire bundles and components for heat damage. Do the inspections following the Accomplishment Instructions in Hawker Beechcraft Mandatory Service Bulletin No. SB 24-4050, dated November 2010.
Before further flight after the inspection required in paragraph (h) of this AD, repair or replace any heat damaged wires or components following the Accomplishment Instructions in Hawker Beechcraft Mandatory Service Bulletin No. SB 24-4050, dated November 2010.
