Video Makes PT6A Engine Rigging Simple For Cessna Operators

This article originally appeared on the P&WC Airtime Blog.

Following the success of our King Air rigging videos last year, we’ve released new content for Cessna Caravan mechanics that helps make rigging easier and more transparent for PT6A operators.


Last year, we provided King Air 200 and 350 operators with videos that shed light on the complex art of rigging – the process of hooking up engines to the aircraft so they’re perfectly balanced and perform optimally.

Following the positive feedback from our customers, we decided to turn the videos into a series focusing on various models. We’ve just launched the next set of videos, which target Cessna Caravan and Grand Caravan EX operators.

“We continue to innovate so our customers can easily access the support and information they need, when and where they need it. Our Airtime blog and social media channels are great tools for doing that, as these videos demonstrate,” says Rob Winchcomb, Owner Pilot and Manager, Customer Service at Pratt & Whitney, who played a key role in producing both sets of videos.

For the latest series, the production team traveled to Belize, where our customer Tropic Air generously agreed to let us use a PT6A-114A-powered Caravan and a PT6A-140-powered Grand Caravan EX. With the help of their maintenance technicians, the team shot footage of the rigging process, including engine adjustments in the run bay, over five days.

Rigging is an important – and often underappreciated – aspect of aircraft performance, notes Rob. Properly rigged engines have many benefits for customers:

  • Reduced pilot workload thanks to improved engine handling
  • More time on wing due to fewer unscheduled maintenance events
  • Improved passenger and crew comfort
  • Lower direct operating costs
  • Less time spent on initial engine and accessory installation time
  • Reduced environmental footprint because of fuel savings relating to more efficient performance

While the rigging process is broadly similar from one engine to the next, each model has its own intricacies and subtleties. Explaining these in writing might require a couple of pages of detailed description. In a video, on the other hand, the explanation can be condensed into 10 or 20 seconds and is much more effective, since customers can see exactly what to do on an engine identical to their own.

They say a picture’s worth a thousand words, in which case a video is like an entire book. These videos take what’s written in our engine manuals and bring it to life. You can see the instructions being applied in practice.

Like the King Air rigging videos, the new Cessna videos demonstrate the basics of setting up the control system, rigging the engines and making final adjustments. But, as Rob points out, thanks to the lessons learned from producing the first round of King Air videos, the new ones provide viewers with an improved experience.

“We’ve taken it up a few levels,” says Rob with satisfaction. “The content is cleaner and flows more smoothly.”

By analyzing how people were watching the King Air videos – such as where they would stop, go back and rewatch a particular section – the team also identified which information delivered the most value. The Cessna videos take this into account.


The videos contain what Rob calls “a-ha moments,” where the visual demonstration of a particularly tricky point immediately clarifies it for the customer. One example is serrated washers.

We knew customers were struggling with adjusting the serrated washers. In the video, we really break down why we want them to adjust it and why it’s important. When they see it on screen, it suddenly makes sense.

Likewise, the visual explanation of how to rig the condition lever makes it much easier to understand. The videos also share handy practical tricks that help technicians avoid the need for special tooling, such as how to use a folded piece of paper for measuring angles.

The goal with these rigging videos is three engine runs and you’re done. This will save our customers time and fuel by ensuring proper, consistent rigging, whether for a single aircraft or an entire fleet. The videos supplement our maintenance manuals by taking what’s written there and bringing it to life.

The PT6A Engine Proves Its Worth Time And Time Again

This article originally appeared on the P&WC Airtime Blog.

No one appreciates the PT6A’s reliability more than customers flying in inhospitable environments, who stake their lives on its performance – like Quest Kodiak aircraft pilot Mark Brown.

Mark Brown still vividly recalls the nerves he felt before embarking on his first flight across the open ocean a few years ago.

Marketing director and factory demo pilot for Quest Aircraft, Mark has aviation in his blood. He was born into a family of pilots and flew for the first time at the age of 13 – but even he could not help wonder about flying solo across the Atlantic on a Kodiak powered by a single PT6A-34 engine.

Maintenance Repair & Overhaul: Another Approach To Monitoring PT6A Engine Health?

High-tech sensors and systems may not be the only way to monitor engine health. Pratt & Whitney Canada has embarked on a project called Oil Analysis Technology, applying it first to the PT6A engine. But Program Manager Frederique Richard says the approach may have much wider applications.

Covington Aircraft PT6 Engine Trainings

Popular Training Highlight:
Pratt and Whitney PT6 Engine Series

At CovingtonAircraft, we have a variety of customers come in and ask us about the different PT6 Engine training opportunities we provide. We realize that not everyone knows we provide trainings and that we do more than aircraft overhaul and maintenance. We asked our Executive Vice President at Covington Aircraft, Aaron Abbott, about what makes us special when it comes to trainings and this is what he said.


What is our most popular training at Covington?

Aaron: “Our most popular training is centered around the PT6A engine series.  We have pilots and mechanics looking for PT6A Pilot Familiarization as well as Line Maintenance training.”

How much do the trainings cost?

Aaron: “Our trainings can be an extensive process, but it also meets a customer need, so we provide it as an added value service to our clients for FREE. We do offer some charged-based training, but it’s generally just to cover costs associated with different catering, materials or something along those lines.”

What is the farthest distance someone has traveled for a training?

Aaron: “We have people come to us on a regular basis from all across the states as well as from Central and South America.  We will also work with customers in order to set up and conduct trainings at their facilities around the world.”

At Covington Aircraft, we do our best to provide the types of training clients need, and we’re happy to help anyone who wants to learn safety and the art of maintaining an aircraft.

PT6 Engine Series: It’s the World’s Most Popular Engine for a Reason

As the world’s most popular engine in its class, the Pratt and Whitney Canada PT6 engine series continues to be the standard for aviators everywhere.  Ever since its development in the late 1950’s, the PT6 engine has combined dependability and versatility with the latest in technology to create an engine that withstands the test of time.


History of PT6A

After successfully designing and manufacturing the Wasp radial engines in the first half of the 1900’s, Pratt & Whitney Canada decided to branch out and begin working on a turboprop engine design.  The first PT6 engine took flight on a Beech 18 aircraft in 1961, and the engines began being mass-produced in 1963.  In just 40 short years, over 36,000 PT6A engines have been manufactured, accumulating 300 million flying hours.

Present Day

Today, there are over 65 different PT6A engine models, providing flexibility for various types of aircraft installations.  From commercial and general aviation to corporate and agricultural planes, Pratt and Whitney Canada engines can be found on aircraft in over 170 countries.
