Repair any broken or loose wires and terminals before further flight. (b) Install Piper Kit No. 754475, or FAA approved equivalent, leaving sufficient slack in the wires between the new clamp and the safety switch to prevent pulling of the wires. (Piper Service Letter No. 379, dated July 12, 1962, pertains to this subject.) This directive effective September 28, 1964.
98-08-05: This amendment adopts a new airworthiness directive (AD) that applies to certain Industrie Aeronautiche e Meccaniche (I.A.M.) Model Piaggio P-180 airplanes. This AD requires inspecting the main landing gear (MLG) for interference between the MLG drag brace link and the MLG retraction actuator, and modifying this area if interference is found. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. The actions specified by this AD are intended to prevent MLG failure caused by interference between the MLG retraction actuator and the MLG drag brace link, which could result in loss of control of the airplane during landing operations.
2018-11-14: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-300 and -300F series airplanes. This AD was prompted by reports of fatigue cracking on airplanes with Aviation Partners Boeing winglets installed. This AD requires high frequency eddy current (HFEC) inspections for cracking of the lower outboard wing skin, and repair or modification if necessary. This AD also requires one of three follow-on actions: Repeating the HFEC inspections, modifying certain internal stringers and oversizing and plugging the existing fastener holes of the lower wing, or modifying the external doubler/tripler and doing repetitive post-modification inspections. We are issuing this AD to address the unsafe condition on these products.
98-07-12: This amendment supersedes an existing airworthiness directive (AD), applicable to all Dornier Model 328-100 series airplanes, that currently requires repetitive tightening of the screws and quick-release fasteners on the wing/body fairing panels. This action will continue to require the repetitive tightening of these parts on certain airplanes. This amendment requires the installation of new fastener systems for those panels on certain airplanes and the application of new torque values. Accomplishment of these actions will terminate the requirement for repetitive tightening of the screws and fasteners of those airplanes. In addition, the AD will limit the applicability of the existing AD by removing certain airplanes. This amendment is prompted by the manufacturer s development of new fastener systems that will not vibrate and loosen. The actions specified by this AD are intended to prevent separation of loosened wing/body fairing panels from the airplane, which, if notcorrected, could lead to structural damage to the horizontal or vertical stabilizer, and potential injury to persons on the ground.
2005-18-06: The FAA is superseding an existing airworthiness directive (AD), which applies to all Bombardier Model CL-600-2B19 series airplanes. That AD currently requires revising the airplane flight manual (AFM) to provide the flightcrew with operating limitations and procedures to enable them to maintain controllability of the airplane in the event that aileron control stiffness is encountered during flight. This new AD requires revising the Airworthiness Limitations section of the Instructions of Continued Airworthiness to incorporate certain repetitive tasks for the aileron control system and requires a briefing to advise flightcrews that certain aileron control checks are no longer required. After accomplishing the applicable initial tasks, the existing AFM revisions for the aileron control check may be removed from the AFM. This AD results from the development of terminating actions for the AFM revisions. We are issuing this AD to prevent aileron control stiffness during flight, which could result in reduced or possible loss of controllability of the airplane. DATES: This AD becomes effective October 6, 2005. The Director of the Federal Register approved the incorporation by reference of Canadair Regional Jet Temporary Revision 2B-2068, dated December 13, 2004, listed in the AD as of October 6, 2005. The Director of the Federal Register approved the incorporation by reference of Canadair Regional Jet TR RJ/109-2, dated August 9, 2002, as of October 10, 2002 (67 FR 60117, September 25, 2002).
