Two of the purposes of this procedure are to
assist in identifying problems with cylinders in service and to
provide a preventive maintenance checklist to utilize in
identifying and correcting factors which, if left unaddressed,
can lead to reduced cylinder service life. The TCM TopCare
Health Check Inspection is intended to supplement the checks
normally prescribed by TCM and the airframe manufacturer relating
to factors affecting cylinder life and should be conducted at
least once per year in conjunction with a regularly scheduled
inspection.
TCM recommends that each operator of a TCM
powered aircraft have the TopCare Health Check Inspection
performed annually in conjunction with a regularly scheduled
inspection to identify cylinder condition and installation items
which can result in reduced cylinder life.
The points of the TopCare Health Check are:
Cylinder Differential Compression Check And
Trend Monitoring
Cylinder Borescope Inspection, As Required
Oil Consumption Trend Monitoring
Oil Analysis Trend Monitoring
Baffle Condition Inspection
Induction System Examination
Cowling Inspection And Cowl Flap Operational
Check
Ignition System Inspection
Fuel System Setup
Verification Of Accuracy Of Engine Gages
Flight Test
NOTE: In order to perform the TopCare Health
Check Inspection, all applicable aircraft, engine, and STC
holder's manuals, instructions and service information must be
available and utilized. Use the TopCare Health Checklist Form to
document the results of the following inspections and required
repairs and adjustments. The latest version of TCM Service
Bulletin SB96-12 provides additional cylinder inspection criteria
that should be performed in addition to the inspections called
for in the details of each item above in SID97-2.
