A Brief Look at the PT6A Powered Beechcraft Model 99 & Variants
The Beechcraft Model 99 is a civilian aircraft produced by the Beechcraft. It is also known as the Beech 99 Airliner and the Commuter 99. The 99 is a twin-engine, unpressurized, 15 to 17 passenger seat turboprop aircraft, derived from the earlier Beechcraft King Air and Queen Air. It uses the wings of the Queen Air, the engines and nacelles of the King Air, and sub-systems from both, with a specifically-designed nose structure.

PT6A Knowledge: Torque vs. RPM vs. Power
A PT6A-34AG operator asked me why his engine torque value changed on approach after he set the torque at a reduced amount for descent. When he reset the rpm from 2000 to 2200, he noticed that the torque reduced further to a value that was lower than needed.

The Perils of Having an Oil Starved PT6A & What To Do About It
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.
