We're just finishing the first 100-hour inspection on our new aircraft that has a Lycoming TIO-540. The airframe sailed through the inspection with only a couple minor issues that shouldn't present future problems. The engine is a different story. The mechanic discovered that the timing was off between 4-5 degrees (advanced) on the left mag, which led him to check the internals of the mag for wear. . .upon opening the mag, he discovered it FULL of oil. The timing for the right mag was spot on spec but he opened it and discovered that it too was full of oil. Lycoming warranteed two new mags for us without question.
This aircraft has 93 hours TT. . .my concerns:
--That we've been flying this turbocharged engine with the advanced timing on the left mag causing detonation. How has this affected engine longevity? What damage, if any, has been done?
--How did this engine leave the factory with the mag timing so far off?
--What are the odds that BOTH mags would seep oil? Bad batch of seals? Poor quality control at Champion (Slick)?
I'll be talking to a Lycoming tech rep today about these issues. . .should be interesting. . . I'm quite dismayed about this.
