Dodgy practice in GA 50 hour check
I recently took my aircraft for a 50 hr check (on 20% extension ie over 2000 hrs). The JAR145 approved maintenence people said that compression was lousy (about 50-60% of published figures) and that the aircraft needed a new engine immediately (which would have been a huge surprise considering they had been the maintainers for 2 years and the engine had been running fine during that period). Needless to say I got a second opinion from a recommended source (another JAR145 facility) and they found that the engine was in fact in vg condition considering its age and compressions were within a satisfactory tolerance - in fact they tried to see if they could reproduce these figues under any conditions and they couldn't. I am highly miffed and considering what action is possible against this organisation. Any views?
