A leaking oxygen hose fitting likely led to the fatal crash of a turbonormalized Mooney M20 Acclaim off the coast of Atlantic City on Sept. 10, 2015. Dr. Michael Moir, a dentist from Gaylord, Michigan, was the only one aboard the aircraft, which flew on autopilot without contact with ATC for more than two hours […]

Some years ago I had an engine stoppage in a Piper Aztec. It was during climbout, shortly after I had shut off the aux pumps. Yes, I had shut them off one at a time. I turned the pumps back on and the affected engine restarted. A bit of troubleshooting revealed that the left engine […]

Air France plans to ferry a damaged A380 back to France from Goose Bay, Newfoundland and Labrador on three engines but before it can do that it has to install a new engine that won’t be running. The aircraft lost the front section of its No. 4 engine, including the 10-foot fan, over Greenland on […]

Air France is facing a daunting technical challenge to repair an extensively damaged A380 at one of Canada’s most remote airports. Flight 66 from Paris to Los Angeles was almost across the Atlantic when the No. 4 engine had an uncontained failure that blew off the cowl and caused the fan to separate. The crew […]

An engine upgrade for the King Air 350 by Blackhawk Modifications, based in Waco, Texas, is now certified by the FAA, the company announced this week. The upgrade package includes two factory-new Pratt & Whitney Canada PT6A-67A engines, plus two new five-blade composite propeller assemblies and spinners from MT Propellers. Training, support and a warranty […]

When I plopped my weary butt into a chair for Continental’s presser at AirVenture last month, what’s the first thing I see on the show-and-tell stand? A couple of Lycoming roller tappets and an angle-valve cylinder. Uh-oh, I thought, really bad timing for Lycoming. And it relates directly to what’s going on with the current […]

The magnetos we’ve been relying on to fire our aircraft’s spark plugs may be the trailing edge of technology, yet if cared for appropriately, they are remarkably reliable. It’s the cared for part of the equation that matters—because they do require regular maintenance, otherwise some failure modes can mean engine stoppage or even catastrophic engine […]

When you’ve been flying an individual homebuilt airplane as long as we have (22 years, to be exact), you encounter a lot of opportunities for improving on your product. Occasionally these “improvements” come because of malfunctioning equipment. That’s certainly happened to me. Yet every now and then, you just want a little change. Either way, […]

Lycoming issued a Mandatory Service Bulletin on Monday that requires owners and operators of its engines to check them for connecting rods that contain bushings that do not meet Lycoming Engine’s specifications. The bushings were manufactured between specified date ranges from November 2015 to as late as February 2017. The service bulletin specifies the dates […]

With minimal fanfare, composite propellers have been appearing as original equipment on more and more airplanes and more and more owners are finding that they are an option for their airplanes when it comes time for an overhaul or replacement. Composite props are more expensive than their aluminum counterparts, so we were curious why owners […]
