EASA SIB 2011-16: Teledyne Continental Ignition Systems (formerly Bendix) Magneto Capacitor Installation

What to do

Owners and operators of piston engine aircraft with Teledyne Continental D-2000 or D-3000 series magnetos should review and consider implementing the capacitor installation instructions detailed in Service Bulletin SB651. There is no mandatory compliance deadline, but proactive action is advised to maintain safe operation. For further information, stakeholders can contact EASA or Teledyne Continental Motors directly.

Summary

EASA Safety Information Bulletin SIB No: 2011-16 addresses the installation of magneto capacitors on piston engine aircraft equipped with Teledyne Continental Ignition Systems (formerly Bendix) D-2000 or D-3000 series magnetos. The bulletin references a safety recommendation following an incident investigation involving a SOCTA TB-10 'Tobago' aircraft. It provides guidance for owners and operators to review and implement revised capacitor installation instructions as outlined in Teledyne Continental Ignition Systems Service Bulletin SB651.

What changed

This bulletin does not introduce new mandatory regulations but highlights the importance of implementing the capacitor installation instructions from Service Bulletin SB651 dated 17 March 1995. It informs stakeholders that EASA has reviewed the safety concern and determined it does not currently warrant an Airworthiness Directive. The document encourages voluntary compliance to enhance safety.

Why it matters

For aviation professionals, this bulletin emphasizes the potential safety impact of proper capacitor installation on affected magnetos, which may influence engine ignition reliability. Operators and maintenance organizations should be aware that adherence to the recommended service bulletin can help prevent incidents related to magneto capacitor issues. Although not mandatory, following these recommendations supports safe aircraft operation and risk mitigation.
