EASA
AIRWORTHINESS DIRECTIVE
AD No.: 2011-0010
Date: 20 January 2011
Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with
Regulation (EC) No 216/2008 on behalf of the European Community, its Member States
and of the European third countries that participate in the activities of EASA under Article
66 of that Regulation.
This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301,
the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person
may operate an aircraft to which an Airworthiness Directive applies, except in accordance with the requirements of that
Airworthiness Directive unless otherwise specified by the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the
Authority of the State of Registry [EC 216/2008, Article 14(4) exemption].

Engine controls – Engine Condition Control Cable – Inspection
/ Replacement
Manufacturer(s):
EADS-CASA; Construcciones Aeronáuticas S.A.(CASA)
Applicability:
CN-235-100, CN-235-200 and CN-235-300 aircraft with serial numbers
(S/N) from C-030 to C-149.
Reaso110:
EADS-CASA received reports of engine condition control cable (Part Number
(P/N) 35-56382-0003) failures that, in one of the cases, occurred during the
starting phase of one engine which led to an engine shut down following the
procedures described within the Aircraft Operation Manual.
The investigation revealed that the cable failure is due to a fracture in the area
of the pulley MS 20219-1. The root cause of the fracture is an unsuitable ratio
between the diameter of the pulley and the cable type and diameter.
This condition, if not detected and corrected, could lead to the engine
condition control cable failure and consequent runway excursion if it occurs
during take-off or reduced control of the aeroplane if it occurs during flight.
To address this condition, EADS-CASA has developed an engine condition
control cable P/N 35-56382-0005 with improved characteristics.
For the reason described above, this AD requires, at first, inspections for good
condition of the engine condition control cable, and its replacement
(scheduled or depending of the inspection findings) with engine condition
control cable P/N 35-56382-0005.
