Airworthiness Directive · Amendment 39-16916 · Engine controls
EADS CASA (Type Certificate Previously Held by Construcciones Aeronauticas, S.A.) Airplanes
This AD applies to EADS CASA (Type Certificate previously held by Construcciones Aeronauticas, S.A.) Model CN-235-100, CN-235-200, and CN-235-300 airplanes; certificated in any category; serial numbers C-030 through C-149 inclusive.
We are adopting a new airworthiness directive (AD) for certain Model CN-235-100, CN-235-200, and CN-235-300 airplanes. This AD was prompted by reports of failures of the engine condition control cable which led to an engine shut down. This AD requires an inspection to determine the part number of the engine condition control cable, repetitive inspections for excessive wear of the affected engine condition control cable, and replacement of the affected part. We are issuing this AD to detect and correct failure of the engine condition control cable which could cause a consequent runway excursion during take-off, or reduced control of the airplane during flight.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 9 months or 300 flight hours, whichever occurs first after the effective date of this AD, inspect to determine whether the engine condition control cable has part number (P/N) 35-56382-0003. If an engine condition control cable having P/N 35-56382-0003 is installed, within 9 months or 300 flight hours, whichever occurs first after the effective date of this AD, do a detailed inspection for excessive wear of the engine condition control cable (including control rods, levers, and pulleys near the flight compartment center console having incorrect freedom and range of movement, incorrect assembly and locking, distortion, damage, corrosion, incorrect security of attachment; and control rod end fittings having excessive wear, i.e., kinks or distortion, corrosion, reduced diameter of cable, and broken wires); in accordance with Section 76-10-00, “Power and Condition Control,” Block 601 (Configuration 1), “Inspection/Check,” Paragraph 1.B., of the Airbus Military CN-235 Aircraft Maintenance Manual, Revision 57, dated July 15, 2010.
For airplanes with engine condition control cable having P/N 35-56382-0003: Within 9 months or 300 flight hours after doing the detailed inspection required by paragraph (g) of this AD, whichever occurs first, repeat the detailed inspection specified in paragraph (g) of this AD.
If, during any inspection required by paragraph (g) or (h) of this AD, excessive wear of the engine condition control cable is found: Before further flight, replace the engine condition control cable with P/N 35-56382-0005, in accordance with Section 76-10-12, “Power and Condition Control Cables,” Block 401 (Configuration 1), “Removal/Installation,” Paragraph 3., of the Airbus Military CN-235 Aircraft Maintenance Manual, Revision 57, dated July 15, 2010.
Within 27 months or 900 flight hours, whichever occurs first after the effective date of this AD: Unless the engine condition control cable has already been replaced in accordance with paragraph (i) of this AD, replace the engine condition control cable having P/N 35-56382-0003 with an engine condition control cable having P/N 35-56382-0005, in accordance with Section 76-10-12, “Power and Condition Control Cables,” Block 401 (Configuration 1), “Removal/Installation,” Paragraph 3., of the Airbus Military CN-235 Aircraft Maintenance Manual, Revision 57, dated July 15, 2010.
As of the effective date of this AD, no person may install an engine condition control cable having P/N 35-56382-0003, on any airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
