This document makes a correction to Airworthiness Directive (AD) 2005-12-20, which was published in the Federal Register on June 20, 2005 (70 FR 35370), and applies to certain The Lancair Company (Lancair) Model LC41-550FG airplanes. We incorrectly referenced the affected airplane model as LC41-550F in the applicability section. The correct airplane model is LC41-550FG. This action corrects the regulatory text.
A correction restates part of an AD that was published incorrectly. It is not an additional requirement and it does not change the AD number or its effective date.

Full official abstract
The FAA is adopting a new airworthiness directive (AD) for certain The Lancair Company (Lancair) Model LC41-550FG airplanes. This AD requires both visual and dye penetrant inspections of the elevator torque tube assembly for cracks. If a crack is found, this AD requires replacement with a modified assembly that incorporates a steel doubler. This AD also requires replacement of the modified elevator torque tube assembly every 300 hours time-in-service or 18 months (whichever occurs first). This AD results from cracks found in the weld area of the elevator torque tube assembly. We are issuing this AD to detect and correct cracks in the elevator torque tube assembly, which could result in failure of the elevator torque tube assembly and subsequent loss of control of the airplane.
