Sometimes things happen! It’s not very profound, but it is very true. Engines suffer through prop strikes, wire strikes, hot starts and hard landings. Frequently, post incident inspections reveal minor damage and the engines are repaired and returned to service promptly. Recently, engines have been brought to Covington for investigation because “things” have happened to them. One was a reported incident of a starter/generator arcing. The starter/generator malfunctioned and was replaced. While the maintenance appears to have been performed properly, “things” still happen. Here is what we found upon disassembly:
An indication of electrical discharge was noted from the starter gear and all through the accessory gearbox. The #1 bearing failed, which in turn allowed the compressor to shift causing a severe rub of the compressor components and the compressor turbine blades. Another engine suffered from oil starvation:
Another engine suffered from oil starvation:
And a third engine had a failure in the turbine area:
Even though the engines pictured here suffered from in-flight shutdowns, all of the aircraft were able to land safely and all pilots walked away.
Although we understand that “things” happen, we don’t want them to happen to you. If they do, we will work with you no matter where your previous maintenance was done, to ensure that you have a rental/replacement engine as quickly as possible to keep you flying. Remember to be aware of changes in your engine or events that could cause damage. Pay attention to the way it sounds (blade rubbing), looks (metal or debris in oil), smells (oil burning) and feels (vibrations) along with watching the gages. You may be able to detect a problem before some ”thing” happens to your engine.

Piper’s M600 is ideal for an owner pilot transitioning out of a piston-engine-powered aircraft or for a corporate flight department needing short-hop or short-field supplemental lift.
Continue reading A Look at The 2019 Piper M600The success of the first two prototypes of the EMB 100, built by the team of the then CTA (Technical Aeronautics Center) under the leadership of Ozires Silva, gave the engineers the challenge of mass production and commercialization of the aircraft. As such, the Federal Government officially created Embraer on August 19, 1969.

The new nose adds 12 cubic feet of storage space capable of holding up to 250 pounds of additional payload. The utility nose can be used on King Air 350 variants including the 350C cargo version and 350ER extended-range model. The modification is FAA-certified and compatible with both the PT6A-60A and PT6A-67A engines.
“This modification is a response to customer interest in optimizing the flexibility of our King Air 350 platform—equipping the aircraft with additional space for baggage or for special mission applications—and increasing loading configurations,” said Textron Vice President of Defense & Special Missions Sales Bob Gibbs. “The Beechcraft King Air offers the widest range of mission capabilities of our broad product lineup, and we remain committed to continuously enhancing the platform to ensure our customers have the capability to succeed, no matter the mission.”
According to Textron, more than 7500 King Airs have been delivered since the model’s introduction in 1964. Over the last 55 years, the King Air fleet has logged more than 60 million flight hours.
