Slick Service Bulletin, SB2-80C
Magneto Maintenance and Overhaul Schedules
The service and warranty history of Slick magnetos clearly show that the prescribed maintenance and overhaul schedules found in Slick Maintenance and Overhaul manuals L-1020, L-1037, and L-1363 are not being followed. Failure to properly perform the prescribed inspections, maintenance, and overhaul procedures voids Slick warranty and may jeopardize the airworthiness of these components resulting in possible serious equipment damage, personal injury, or loss of life.
Models Affected: All
400 and 600 series magnetos
4000 and 4100 series magnetos
4200 and 6200 series magnetos
4300 and 6300 series magnetos
Requirement: Inspect Slick Magnetos externally every 100 hours and internally every 500 hours.
Primarily affects aircraft with Lycoming engines, however some Continental engines may also be equiped with Slick magnetos.
