PRODUCT: Certain Cessna Aircraft Company Model 560XL airplanes. SUBJECT: Airworthiness Directive 2012-09-01 ACTION: Final Rule
SUMMARY: This AD was prompted by reports of wheel inserts becoming loose and damaging brake assemblies on Model 560XL airplanes. This AD requires an inspection of the torque lug and surrounding components (wheel base, side rim, lock ring) for damage (such as corrosion, cracks, dents, bent areas, damaged or missing paint or primer, or wear on the metal), and of the bearing cup for corrosion, turned cup, or clearance that exceeds limits, and repair as applicable; measuring the torque lugs for width and replacing screws and inserts with new, improved screws and inserts; and re-identifying the wheel assemblies. The FAA is issuing this AD to prevent brake failure, which could result in an airplane not being able to stop on the runway.
