Electrical Equipment

AD/ELECT/68 Bendix Impulse Coupling Inspection 9/2005

Requirement:

CANCELLED.

This AD is cancelled on 1 September 2005.

Background:

This Directive is superseded by AD/ELECT/75 which is only applicable to magnetos installed on certain Lycoming engine models.

Data supplied to the United States Federal Aviation Administration indicated that there was a significant difference in wear and reliability of magnetos installed on Lycoming 540 series engines as compared with other engines.

Teledyne Continental Ignitions Systems Service Bulletin SB643B dated 6 April 2005 provides the manufacturer recommended periods for inspection/overhaul for magnetos installed on all engines.
