COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

 Embraer EMB-110 (Bandeirante) Series Aeroplanes

AD/EMB-110/50 Automatic Propeller Feathering System 1/96 DM

 Applicability: This Directive is applicable to all EMB-110 aircraft.

            Requirement: Inspect the control and test switch of the automatic propeller feathering system in accordance with Embraer Service Bulletin 110-61-0032 dated 6 October 1995.

            Note: CTA (Brazil) AD 95-10-01 Amdt 39-749 refers.

            Compliance: Unless previously accomplished, then within 50 hours time in service after 17 November 1995.

            Background: A report was received of a malfunction of the automatic feathering mechanism of the EMB-110 propeller. Investigations carried out revealed a hidden failure mode not checked by the preflight feathering test. This failure mode was due to a loss of electrical connection between the control and test switch pins and wires soldered to them. Action required by this Directive is intended to provide early detection of this anomaly.
