The "H" engine was one of Lycoming's worst products, bad camshaft material. Numerous failures early in it's life with the resulant FAA Airworthiness Directive requiring a special oil additive. Pretty much a non-issue now since most major oils have this additive as standard. I've got about 2,000 hours with an "H" engine without a single burp. Yea, the stuff after the size tells mechanics about engine and preinstalled accessory oprions (roller tappets, multiple vaccum pumps, alternators, etc), most of it is pretty esoteric for the guy pushing the throttle. You can also run into IO- engines, they have fuel injection instead of carbs. Good luck on the test! Thanks for all the advice Here is another questions 1. On the KOEL in my POH, all that was really there was Placard information...about that the placards were necessary and need to be displayed. Is there something I am missing here in regards to deferrals? One placard had something about Day-Night-VFR-IFR...and info about maneuvers and load limits...but nothing about equipment except further in the equipment list in the WB sec. Thanks JCL |
