Airworthiness Directive · Amendment 39-17683 · Engine controls
EADS CASA (Type Certificate Previously Held by Construcciones Aeronáuticas, S.A.) Airplanes
This AD applies to EADS CASA (Type Certificate previously held by Construcciones Aeronáuticas, S.A.) Model C-212-CB, C-212-CC, C-212-CD, C-212-CE, and C-212-DF airplanes; certificated in any category; all serial numbers, except those that have been modified in production to incorporate EADS CASA Modification 10515.
We are adopting a new airworthiness directive (AD) for certain EADS CASA (Type Certificate Previously Held by Construcciones Aeron[aacute]uticas, S.A.) Model C-212-CB, C-212-CC, C-212-CD, C-212- CE, and C-212-DF airplanes. This AD was prompted by a report of the propeller pitch control (PPC) lever becoming disconnected from the engine due to a missing bolt. This AD requires modifying the PPC lever attachment system. We are issuing this AD to prevent PPC shaft disconnection, which could lead to a loss of propeller pitch control, possibly resulting in uncommanded change to the engine power settings and consequent reduced controllability of the airplane.
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 24 months after the effective date of this AD, modify the PCC lever attachment system of the aircraft engine, in accordance with the Accomplishment Instructions of EADS-CASA Service Bulletin SB-212-76-0009, Revision 1, dated August 03, 2012.
Note 1 to paragraph (g) of this AD: EADS-CASA Service Bulletin SB-212-76-0009, Revision 1, dated August 03, 2012, refers to Honeywell Service Bulletin TPE331-72-2190, dated December 21, 2011, as an additional source of guidance for modifying the cam assembly.
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.
