Air Plains Offers Custom Avionics Panel for Upgraded Cessna 172s

More engine performance meets more panel performance.

There is a common school of thought that if your aircraft is going to be down for maintenance, such as an engine upgrade, you might as well get the other labor-intensive projects—such as an instrument panel upgrade—done at the same time. 

That’s the thought process behind the Advanced Instrument Panel Kit 172XP “alpha” update, developed specifically for Cessna 172 owners planning to upgrade their aircraft engine with Air Plains’ 180 hp supplemental type certificate (STC). Alternatively, if the owner has one of the more than 2,500 172XP upgrades already in the field, the new avionics panel is also an option. Both the panel and the engine updates can be installed by Air Plains at its Wellington, Kansas, facility, or it can be shipped as a complete kit for local installation.

According to Air Plains’ president Katie Church, the company has been supplying the horsepower-upgrade STC since the early 1980s. They noted that often when the customer purchased the 180 hp upgrade, they almost always paired it with a new instrument panel, resulting in what she describes as an “upgrade experience for legacy Skyhawk airframes.” 

“That led us to develop a new, advanced panel kit, available to be shipped along with the engine upgrade, that’s easy for your mechanic to install at the same time, giving the customer essentially a new airplane at a fraction of the cost of a factory model,” she says.

The Flight School Market

The Cessna 172 is the workhorse for many flight schools. Air Plains notes that many schools have taken advantage of the 180 hp upgrade, resulting in better engine performance and a gross-weight increase for their training aircraft. The avionics upgrade is the next logical step, Church says, noting, “With the Alpha avionics upgrade, they can offer a wider range of training programs in one airframe, and they get a trainer that meets a student’s idea of 21st century flying.” An aircraft equipped with the 172XPα advanced instrument panel kit meets all the requirements under FAA FAR 61.129(j) for a technically advanced aircraft (TAA) needed for logging time towards a commercial pilot certificate. 

According to Church, on average, the time between order and delivery of the kit is about six months. Another benefit of adding the 172XPα advanced instrument panel kit to an Air Plains’ engine upgrade order is that both packages can be installed at the same time.  

“You didn’t get your airplane for it to be worked on,” Church says. “If you’re planning on a new Air Plains’ 180 hp upgrade, get the most out of your planned downtime during your engine upgrade and leave the maintenance facility with an essentially new 172.”
