CATEGORY 5
AIRCRAFT ENGINE
SIL 03-2A Technical Portions FAA Approved Supersedes M85-7
Correction to engine / spark plug application Table 2 and 3.
SUBJECT:
CURRENTLY ACTIVE APPROVED SPARK PLUG APPLICATION
PURPOSE:
Provide listing of currently approved spark plugs for TCM Engines
COMPLIANCE: MODELS AFFECTED:
As Required when replacing spark plugs. ALL
GENERAL INFORMATION: The following Tables number 1, 2, 3 , and 4 list the most commonly used spark plugs by engine model. Additional listings of approved spark plugs may be found in the engine’s FAA Type Certificate Data Sheet and the spark plug manufacturer’s data. Refer to the spark plug manufacturer’s data for spark plug servicing information and required specialized tools. Spark plugs must be removed, cleaned, inspected, gapped and position rotated every 100 hours. Refer to Chart 1 for spark plug rotation sequence. Always install a new spark plug gasket when servicing spark plugs or installing new spark plugs. Chart 2 provides spark plug electrode gap specifications using an alpha code referenced in Table 1, 2 and 3. CAUTION:
Failure to install a new spark plug gasket each time the spark plug (s) are installed may result in incomplete sealing of the combustion chamber, loss of spark plug heat transfer, spark plug over heating, possible pre-ignition / detonation and internal engine damage.
GENERAL INSTALLATION PROCEDURES: In the event spark plug manufacturer’s instructions are not available the following procedure may be used. 1. 2. 3. 4. 5. 6.
Always install spark plugs with new copper gasket. Sparingly apply anit-seize to the spark plug threads. DO NOT APPLY ANTI-SEIZE TO THE FIRST THREAD. Always use a six point deep socket. Thread spark plug by hand into cylinder to within one or two threads of the gasket. If this is not possible, cylinder head threads or spark plug threads need to be cleaned. Torque spark plugs to 300 to 360 inch pounds using a currently calibrated torque wrench. Handle spark plug leads with clean, dry hands.
