PURPOSE

To transmit Teledyne Continental Ignition Systems Critical Service Bulletin CSB 02-8: Teledyne Continental
Motors Ignition System Critical Service Bulletin CSB 664.
TCM Critical Service Bulletin CSB 664 requires an inspection and if required, replacement of part number
10-400558 magneto capacitors that could have an open circuit. This condition if not corrected may allow a
hot magneto condition even when the ignition switch is in the "OFF" position which could result in an engine
start if the propeller is moved.

WARNING: DO NOT MOVE THE PROPELLER OF ANY ENGINE CONTAINING AN AFFECTED

MAGNETO CAPACITOR. THE ENGINE COULD START, REGARDLESS OF IGNITION
SWITCH POSITION, CAUSING PERSONAL INJURY OR DEATH.
COMPLIANCE
Mandatory; shall be accomplished on receipt of TCM Critical Service Bulletins CSB 02-8 and CSB 664 (or

OWNER NOTIFICATION
On December 23, 2002 the following Owner Advisory message will be sent to applicable owners of record in
SEB02-7A.
Dear Cessna Owner:
This Owner Advisory is to inform you that SEB02-7 has been issued to transmit Teledyne Continental Ignition
Systems Critical Service Bulletin CSB 02-8: Teledyne Continental Motors Ignition System Critical Service
Bulletin CSB 664.
TCM Critical Service Bulletin CSB 664 requires an inspection and if required, replacement of part number
10-400558 magneto capacitors that could have an open circuit. This condition if not corrected, may allow a
hot magneto condition, even when the ignition switch is in the "OFF" position, which could result in an engine
start if the propeller is moved.
Your airplane may be affected if it is equipped with New (10-) and Rebuilt (BL-) S20, S200 and S1200 series
magnetos of all part numbers manufactured, ordered or received from TCM Ignition Systems between
August 1, 2002 and August 31, 2002 identified within the following serial number sequences: D02HA001
through D02HA999, D02HA001 R through D02HA999R, E02HA001 through E02HA999, E02HA001 R through
E02HA999R, F02HA001 through F02HA999 and F02HA001R through F02HA999R.
NOTE: Records indicate that two magnetos were shipped from Cessna between August 1, 2002 and August
31, 2002.
Also affected are all part number 10-400558 capacitors as described in TCM Critical Service Bulletins CSB
02-8 and CSB 664 (or latest revisions).
NOTE: Records indicate that no 10-400558 capacitors were shipped from Cessna between August 1, 2002
and August 31, 2002.

WARNING: DO NOT MOVE THE PROPELLER OF ANY ENGINE CONTAINING AN AFFECTED

MAGNETO CAPACITOR. THE ENGINE COULD START, REGARDLESS OF IGNITION
SWITCH POSITION, CAUSING PERSONAL INJURY OR DEATH.
Compliance is mandatory; shall be accomplished on receipt of TCM Critical Service Bulletins CSB 02-8 and
CSB 664 (or latest revisions).
The information contained in the referenced Cessna Service Bulletin shall be considered an amendment to the

SUBJECT: MAGNETO CAPACITOR P/N 10-400558 REPLACEMENT.

PURPOSE: TCM has identified a quantity of magneto capacitors part number 10-400558
that could have an open circuit, which would allow a hot magneto condition
even when the ignition switch is in the "OFF" position. Critical Service
Bulletin provides inspection and disposition instruction for service spare
capacitors and magnetos that may contain these capacitors.

COMPLIANCE: On receipt of this Critical Service Bulletin. Make certain that no one is
allowed to move the propeller on an engine suspected of containing an affected
capacitor. This could result in an engine start.

PARTS
AFFECTED: All New (10-) and Rebuilt (BL-) S20, S200 and S 1200 Series magnetos of all
part numbers manufactured, ordered or received between August 1, 2002 and
August 31, 2002 identified within the following serial number sequences:
D02HA001 through D02HA999, D02HA001R through D02HA999R
E02HA001 through E02HA999, E02HAOO1R through E02HA999R
F02HA001 through F02HA999, F02HA001R through F02HA999R
All part number 10-400558 capacitors.

WARNING: DO NOT MOVE THE PROPELLER OF ANY ENGINE CONTAINING

AN AFFECTED MAGNETO CAPACITOR. THE ENGINE COULD
START, REGARDLESS OF IGNITION SWITCH POSITION, CAUSING
PERSONAL INJURY OR DEATH.
A. INSPECTION
1. Inspect the serial number stamped on the magneto data plate to determine if it falls within the
sequences listed in "PARTS AFFECTED" above. Also, regardless of magneto serial number,
determine if P/N 10-400558 capacitor has been installed.
2. If the magneto serial number is affected or capacitor P/N 10-400558 has been installed in any
magneto and for all P/N 10-400558 in inventory, inspect the capacitor potting
compound/insulator type.
3. If capacitor P/N 10-400558 potting/insulator material is black (reference Figure 1), the
capacitor must be returned to TCM in accordance with Section D.
4. Any capacitor with red insulator material (reference Figure 2) does not require replacement in
accordance with this Critical Service Bulletin.

MAGNETOS
1. Remove airframe and engine components necessary to gain access to the magneto
capacitor/contact point cover.
2. Remove 4 magneto cover screws. While removing the cover, carefully remove capacitor lead
from contact points terminal, noting terminal placement and lead orientation for reassembly.
3. Remove 2 screws securing the capacitor to the cover and remove capacitor. Remove o-ring
packing from affected capacitor.
4. Place o-ring on new capacitor (reference Table 1). Secure capacitor to magneto cover with 2
screws. Torque screws to 8 - 12 in lbs.
5. Attach serviceable replacement capacitor terminal to contact points terminal in accordance
with instructions in the applicable Service Support Manual.
6. Attach magneto cover using 4 screws. Torque screws to 20- 25 in lbs.
7. As applicable, record the magneto serial number to be supplied to TCM distribution for
warranty application.
8. As applicable, make a engine log book entry as to inspection and/or replacement of the part
number 10-400558 capacitor in accordance with TCM Critical Service Bulletin CSB02-8.
