Bendix Magneto Coils and Rotating Magnets 10/95

Applicability: Teledyne Continental Motors (TCM) Ignition Systems (formerly Bendix) magnetos as listed below. Magnetos manufactured by Bendix in Jacksonville FL and those manufactured by TCM in Atlanta GA (as indicated on the data plate) are excluded.

S-20, S-200 and S-600 series magnetos with either serial numbers below 2000000 without any letter prefix or with serial numbers below 16058 having the letter `A” prefix (for example A16057).

S-20, S-200 and S-600 series magnetos with data plates marked

`REMANUFACTURED” and with serial numbers below 901001.

S-1200 series magnetos with either serial numbers below 2000000 without any letter prefix or with serial numbers below 132844 having the letter `A” prefix.

S-1200 series magnetos with data plates marked `REMANUFACTURED” and with serial numbers below 901001.

Note 1: CASA has received reports of some confusion as to what is meant by S-20, S- 200, S-600 and S-1200. A typical example is S6RN-25, where the `S” designates a single type ignition unit, the `6” designates the number of engine cylinders, the `R” designates right hand rotation, the `N” is the manufacturer designator (this did not change when TCM purchased the Bendix magneto product line) and the number after the dash indicates the series (a -25 is a S-20 series magneto, while a -1225 is a S- 1200 series magneto.

Note 2: If a Bendix magneto data plate has been replaced with an overhaul facility's data plate, this Directive is still applicable to that magneto as the magneto is a Bendix magneto.

Note 3: Yellow Bendix or TCM service spare data plates may have been installed during field overhaul, use the magneto model and serial number to determine the applicability of this Directive.

Note 4: The paint on some early data plates may have been obliterated and the data plate may appear silver in colour, use the magneto model and serial number to determine the applicability of this Directive.

Requirement: For Bendix S-20 and S-200 series magnetos, inspect and if necessary, replace Bendix ignition coils and rotating magnets identified in the Detailed Instructions of TCM Ignition Systems Mandatory Service Bulletin MSB644 dated 4 April 1994 with appropriate serviceable ignition coils and rotating magnets.
