Last week Lycoming Engines hosted Stu Horn, president of Aviat Aircraft, who flew the company’s Aviat Husky CNG to Williamsport, Pa., which is powered by a Lycoming IO-360-A1D6. The engine was modified to be the world’s first dual-fuel compressed natural gas (CNG) aircraft, and can be powered by CNG or 100LL aviation gasoline with the flip of a switch. Members of the Lycoming engineering team gathered to examine the engine and its modifications during the visit.

Ask Paul: Does my engine need an oil filter?

Q: I just purchased a 1978 Citabria 7ECA with a Lycoming O-235-C1. Just had my first oil change done — it has no oil filter! Just one, maybe two, screens.  Are these screens just as effective if I change my oil every 25 hours?  Should I add an oil filter? Is that even possible?  I run Phillips X/C and CamGuard. Your thoughts?
