Whether it involves recording and inputting data manually or using the latest automated Digital Engine Services, Engine Condition Trend Monitoring delivers net gains for all PT6A customers.
A WORTHWHILE PAYOFF
Rob Winchcomb, PT6A Customer Manager, is the first to admit that doing Engine Condition Trend Monitoring (ECTM) by hand is a hassle.
It requires writing down key engine and aircraft data at a set time during each flight once the plane is at a stable cruising speed, inputting the recorded figures into a computer after landing and sending them to the analysis company for comparison with the results of previous flights.
For busy operators who already have plenty on their plate during a flight, the extra work might seem like an unnecessary nuisance. That’s why Rob’s customers always ask him the same question: “What’s in it for me?”
He’s been telling them the same thing for 25 years: “ECTM reduces the cost of ownership, increases the engine’s availability and gives you more peace of mind.”
Rob walks the talk. Thirty years ago, before joining P&WC, he was on the other side of the fence as a customer, began his aviation career with the Royal Flying Doctor Service and working for other regional airlines in Australia. Back then, he was already a strong proponent for recording and using engine condition data, despite having to do it all the hard way—computing the trend values by hand on a Texas Instruments calculator and plotting his own handmade ECTM graphs.
A LITTLE EFFORT, A LOT GAINED
“PT6A engines are very reliable from one inspection to the next, but in my mind the question is, why not take the next step? With ECTM, you can optimize performance and maintenance planning,” says Rob. “It doesn’t cost you much considering the gains it will bring.”
By analyzing parameters such as power, speed and fuel flow on a flight-to-flight basis, ECTM can identify subtle changes in an engine’s performance. Based on the analysis results, P&WC’s engine health monitoring partner CAMP Systems will let the operator and maintenance team know if any actions are required.
Is a sudden 10-degree increase in temperature simply the result of replacing a fuel nozzle set? Is an increased power load due to excess air leaking from the cabin rather than an issue with the engine itself? Do you need to take a look at the compressor? ECTM will tell you.
This kind of detailed insight into engine performance means that issues can be detected and resolved before they turn into costly repairs and affect operation. It also makes it easier for PT6A customers to move to on-condition hot section inspections.
It all adds up to better maintenance planning, lower expenses and increased engine availability.
There’s also a financial benefit when selling a used aircraft. If you’ve been consistently performing ECTM, you’ll have a record to show potential buyers that the engine is well maintained. That will give them more confidence, which in turn enhances your aircraft’s resale value.
AUTOMATED ECTM AND MORE WITH THE FAST™ SOLUTION
Today, many operators can enjoy all the advantages of ECTM with none of the downsides, thanks to P&WC’s FAST™ Solution for proactive engine health management system.
Now available on a growing number of PT6A platforms, the FAST solution captures, analyzes and wirelessly transmits a wide range of engine and aircraft data after each flight, providing detailed, customized alerts and trend monitoring information directly to the operator within minutes of engine shutdown.
“I wish I’d had this technology 30 years ago,” remarks Rob. “It’s light years ahead of what we were doing back then—and it keeps evolving.”
Besides making operators’ lives simpler through automation, the FAST solution also has the capacity for enhanced functionality going forward. For instance, the company is looking at introducing FAST’s propeller vibration trend monitoring technology – available for regional turboprop aircraft – as a solution for PT6A-powered aircraft in the future. That’s another reason why Rob believes it is now the most attractive solution for customers.
Ultimately, though, what’s most important is to be doing ECTM, no matter whether it’s with pen and paper or state-of-the-art digital solutions. “When I talk to customers about FAST,” Rob concludes, “what I’m selling them is not the hardware itself, but the full value of automated ECTM to their operations and asset value.”
Rob has also helped PT6A customers master the art of engine rigging by appearing in a detailed instructional video. Read all about it here.

Blackhawk Modifications has sold 800 of its XP engine upgrades with the delivery of a Phoenix-edition King Air C90-1 with its XP135A engine upgrade. The company also announced that flight testing of its latest program, the XP67A engine upgrade for 12,500-pound and 14,000-pound-gross-weight models of the King Air 300, is underway and that it is continuing a $50,000 pre-certification discount on orders for that program, first announced this summer.
Blackhawk expects the XP67A upgrade for the King Air 300 to deliver improved performance, including a maximum cruise speed of 345 to 350 knots, time to climb from sea level to FL350 in less than 17 minutes, and better performance at higher density altitudes. The upgrade includes two new P&WC PT6A-67A engines with a factory new engine warranty of five years/2,500 hours, installation drawings, STC paperwork, approved flight manual supplement, instructions for continued airworthiness, training from FlightSafety International for PT6A line maintenance, and a two-year subscription to P&WC engine maintenance/parts manuals. Qualifying core PT6A-60A engines will be trade-in credited at $70 per hour each for time remaining on the 3,600-hour TBO.
The STC flight test program for the XP67A upgrade for the King Air 300 will include measuring parameters such as single- and multi-engine handling, aircraft performance, engine and accessory cooling, stall speeds and characteristics, landing characteristics, propeller noise and vibration, and high-speed airframe/engine characteristics. Blackhawk expects FAA STC approval for the upgrade next summer.
Blackhawk’s Phoenix program allows owners of legacy King Airs to upgrade from a menu of options, including engines, avionics, and paint and interior. Blackhawk’s 800th XP upgrade, a 1982 King Air C90-1, was delivered to Gregg and Jan Goodall of Breckenridge, Texas, and replaced the stock PT6A-21 engines with the XP135A engine upgrade, generating a 36 percent increase in available horsepower, a 59 percent increase in climb rate, more than 270 knots maximum cruise speed, and a 19,000-foot single-engine service ceiling. The Goodalls also opted for Phoenix signature paint and interior design, the Raisbeck Epic package, and new Garmin glass-panel avionics including two G600TXi displays, WAAS-enabled GTN 650 and 750, GTX 335 transponder for ADS-B Out, and the L3 Lynx transponder for ADS-B In and Out.

Quest Aircraft is seeking to broaden the customer base for its Kodiak 100 single-engined turboprop with the expansion into the special missions market.
Rob Wells, chief executive of the Sandpoint, Idaho–based airframer, says the utility aircraft has found a successful niche in the charter, commercial short-haul, corporate, and cargo markets, but its unique features make it an ideal platform for other applications, such as law enforcement, surveillance and military transport. “We have been working on a concept for a year now, and there is no shortage of interest,” he says.
The Kodiak’s appeal comes from a host of features including its wing, which has a discontinuous leading edge, giving it “fantastic” low-speed performance.
The Kodiak’s high-wing loading also creates a stable platform – a necessity for a surveillance operation. The Kodiak’s cargo pod can store sensors, and its large cargo door allows for the easy transfer of equipment, while the large windows are “ideal”, Wells says, for an observation role. The aircraft also has a 9.5h loiter time.
In April, Quest introduced the second-generation version of the Kodiak – powered by Pratt & Whitney Canada PT6A-34 – and Wells says response to the aircraft has been “overwhelming”, with 10 examples delivered to date.
The Series II has a host of new enhancements and equipment, including Garmin’s next generation G1000NXi flightdeck; additional storage in the cockpit; a restyled cargo doorstep to “reduce weight and improve functionality”; and improved fuselage seals to provide “even better” soundproofing and cabin ventilation.
Since its introduction in 2008, Quest has incorporated over 200 enhancements into the short take-off and landing Kodiak, including the introduction of two new interiors; an increased landing weight; and the integration of the Garmin GFC 700 automatic flight control system.
FlightGlobal’s Fleets Analyzer database records a global fleet of more than 255 of the all-metal aircraft. The company shipped 31 examples in 2017.

In an aircraft engine, oil is much more than just a lubricant. It plays a number of other important roles, including cooling, cleaning and noise reduction. It’s therefore vital to monitor and analyze oil to ensure it’s doing its job properly.
WHEN AND WHAT TO ANALYZE
Engine oil sampling and analysis are recommended if a visual inspection reveals that the oil is very dark, has an unusual odor or exhibits other abnormal properties. You don’t necessarily have to change the oil, but at the very least, it should be analyzed to determine its total acid number (TAN) and water content.
Typically, the water concentration in brand-new oil varies between 0.02% and 0.04%, or 200 and 400 parts per million (ppm). However, water can enter the engine’s oil system due either to accidental contamination during compressor wash or normal condensation. Since aircraft engine oils easily absorb water and moisture from the air, their water content will rise over time. If it exceeds 1000 ppm, the TAN may rise as well, eventually leading to engine component corrosion.
HOW TO SAMPLE AIRCRAFT ENGINE OIL
When you take an oil sample, identify it with the brand name, engine serial number, total run time (oil life) and engine time since new (TSN) or time since overhaul (TSO). Have the sample analyzed for its TAN and water content by an approved laboratory. If necessary, ask the lab to analyze the oil viscosity and additives as well.
If a parameter exceeds the established limit, it’s recommended that you: 1) drain and discard the oil from the tank; 2) check the condition of the oil filter and, if needed, replace it with a new one; 3) refill the tank with fresh oil.
If you have access to the right kits, you could also perform the analysis yourself. Use a Titra-Lube TAN Test Kit to analyze the oil’s TAN and a HydroScout Analyzer kit for the water content.
RACK YOUR OIL CONSUMPTION
Every time you add oil into your engine, write down the amount so that you can calculate the average consumption. Check this figure against the limits indicated in the maintenance manual. If the engine is using more oil than it should, there may be a part that needs maintenance. For example, a damaged O-ring could be causing a leak, or something may be happening in the engine that’s burning up extra oil.
Oil is key to your engine’s health and performance, so give it the attention it deserves by following the advice above.

A BRIEF HISTORY OF AVIATION GAS TURBINE ENGINE LUBRICANTS
The earliest aviation piston engines were lubricated with natural oils such as castor oil and refined mineral oils. However, they lacked the thermal-oxidative stability needed for high-temperature mechanical systems and would form deposits like gum and lacquer on metal surfaces.
In the 1950s, following research efforts aimed at improving thermal-oxidative stability, synthetic polyester-based lubricants became the base stock of choice for aviation gas turbine engine oils. Thanks to their chemical properties, these lubricants are effective over a wide temperature range, from -65oF to 425oF. They possess good thermal-oxidative stability, high lubricating film strength, good surface wetting, and low friction and wear rates, making them ideal for aircraft engines.
