Electrical Equipment

AD/ELECT/18 Amdt 3 Slick 4000/4100 Series Sealed Non-Repairable Magnetos - Retirement Life 2/2009

Requirement:

CANCELLED.

This AD is cancelled on 12 February 2009.

Background:

This unique Australian AD raised in 1966 against Slick Service Bulletin (SB) No.
2-80B required all Slick 4000/4100 series sealed, non-repairable, magnetos to be retired from service due to the possibility of these magnetos being run beyond their designed life.  The AD did not apply to Slick 4200 series magnetos which can be overhauled.

Compliance was: Magnetos with greater than 700 hours TTIS within 100 hours TIS after 18 April 1991, and those Magnetos with less than 700 hours TTIS prior to exceeding 800 hours TTIS.

As all affected magnetos would have been retired by now, this AD is considered to be no longer required.
