Case: Diesel engine conversion - from 1.7 to 2.0 (march 2014)​​


In 2013, a Swedish flight club acquired our Piper PA28 Cadet (reg.no. D-EHLD, now: SE-LXR) - with a new 2.0 Centurion diesel engine. Before selling it, we had converted its engine from a 1.7 to a 2.0 Centurion diesel engine. See photos below (scroll in the photo bar on the left).

About the Flying Club and its needs
Western Gästrike Flight Club was founded 50 years ago and currently has 100 members, including 20 active pilots. The flying club is located 200 km north of Stockholm and has its own airfield - with very well kept flying club facilities. “Over the years, we have traditionally flown Piper and Cessna aircraft and also invested in ultra light aircraft for a number of years now”, said Alf Persson, who is responsible for Private Pilot License (PPL) in the flying club. “The majority of our ultra light flying is increasing, and we currently have 9 students training to become pilots.”

Too expensive

The club had a PA28, reg.no. SE-FFF, equipped with a traditional aircraft engine, and it was very expensive in terms of fuel costs: Approx. 850 SEK/ hour (equal to EUR 97/ hour, ed.). As a result, the aircraft was standing in the hangar day after day, not being used by the pilots. “It was simply too expensive to take it out for a spin”, Alf Persson explains.

All in on ultra lights – or diesel conversion …?

So, the club had to consider what to do in terms of aircraft: All in on ultra lights…or…? Alf explains: “In the club, we discussed various solutions, including focusing on ultra light aircraft. The conclusion was, that if we wanted to keep using e.g. Piper aircraft, we had to minimize the hourly cost significantly.” They investigated the matter thoroughly, and long discussions and calculations lead to the trading-in of their Piper for a Piper Cadet with a 2.0 diesel engine, that Air Service Vamdrup had used as a demonstrator for the past three years.​

The best recommendations

 “In general, we must say, that reality after the conversion has been much more positive than we expected. We experience no difference when it comes to performance and flying in general – no negative things at all. And our cost per hour is now very attractive. Based on a total flight time of 220 hours, the fuel cost has been 230 SEK/ hour (equal to EUR 26/ hour, ed.). At flight level 95 with 65% power, it is a dream to fly as always – and now even with a fantastic fuel economy.”

Alf is happy and concludes: “We can totally recommend this solution to others. Absolutely. We have had a new start in our club, and our pilots have flown 220 hours during the last 10 months. For us this was a way to maintain flight operations for PPL pilots in our club. And as a result, we face the future with confidence and are very happy that we decided to go for this aircraft. Big thanks to Air Service Vamdrup who supported us all the way.”

Centurion diesel engine Ambassador
As a result of the wonderful cooperation between Western Gästrike Flight Club and Air Service Vamdrup, we have made an agreement with Western Gästrike Flight Club that they will help us visit Swedish flying clubs to demonstrate the diesel engine aircraft to clubs that may be interested. So, do not hesitate to contact us for further info.

New demonstrator in the making
At our facilities in Vamdrup, a new demonstrator is in the making. We have bought a 1999 Cessna 172 that we are converting to our next Centurion 2.0S diesel engine demonstrator.
