Pro Pilot staff report
Data compiled by Conklin & de Decker

Pro Pilot has conducted its Powerplant Product Support Survey for 28 years now, reaching operators worldwide and giving them the opportunity to evaluate the quality of aftersale product support provided by aircraft turbine engine manufacturers.

Williams takes 1st place for the 5th year in a row, with an overall score of 8.85 – improved from 8.78 earned in 2019.

Williams clinched 1st place in all categories except for cost of parts, where they took the 2nd spot. Best category increase was made in response to problems, with a score of 9.29 – up from 8.93 last year.

Pratt & Whitney keeps its number 2 place for the 2nd year in succession. Overall score earned was 8.43 – up from 8.37 last year.

P&W secures 2nd place in response to problems, spares availability, tech manuals, and service satisfaction categories, and 3rd in cost of spares, speed in AOG service, and tech reps. Best category increase was in tech manuals, with an 8.65 score – up from 8.45 last year.

General Electric remains 3rd with an overall score of 8.35 this year compared to 8.29 in 2019. GE obtained 1st place in the cost of parts category, and 3rd in spares availability and tech manuals.

The company’s biggest category improvement was in cost of parts, with a score of 7.51 this year – up from 7.08 in 2019.

Rolls-Royce moves up 1 spot to 4th this year, earning an overall score of 8.21 – up from 7.82 in 2019. It took 2nd spot in speed in AOG service and tech reps, and 3rd in response to problems and service satisfaction.

Rolls-Royce raised all its category scores this year, obtaining the largest growth in tech manuals with a score of 8.35. Last year this number was 7.77 – a substantial difference of 0.58.

Honeywell gains a notch, moving up to 5th this year with an overall score of 8.08 – up from 7.58 last year. This was the biggest overall score gain in the survey, with a 0.50 difference.

Honeywell saw a significant improvement in all category scores, the best being in service satisfaction, with 8.51 this year. Compared to 7.66 last year, this is a 0.85 increase. With these numbers, Honeywell has the largest score advance in the entire survey.

Safran Helicopter Engines (formerly Turbomeca) rounds out the survey, taking 6th place this year. Overall score was 8.05, slightly down from 8.10 last year.

Best category improvement was made in service satisfaction, with an 8.38 score – a difference of 0.12 from the 8.26 earned in 2019.

Jet and turboprop divisions

For the 10th year, Pro Pilot has separated the overall scores for jet and turboprop engine manufacturers, in addition to those in the helo category. The minimum number of evaluations required for the jet and TP divisions was 30, while for helo it was 19.

Some respondents rated a single engine manufacturer with 2 types of aircraft, eg, P&W for a Citation Sovereign (jet) and for a King Air 350 (turboprop). Because of this, there is a small difference between total responses for overall rankings and the rankings by aircraft type.

For overall rankings, this was counted as 1 response (Pratt & Whitney), while for rankings by type of aircraft, it was counted as 2 (jets and turboprops).

Had an internal engine malfunction confirmed by borescope. Williams had a spare engine on a truck on its way for us that very evening. It arrived 2 days later, they installed the spare engine, and we were good to go. We had a 4-day downtime, and that’s simply unreal! I’ve been in this business for a long time now, and it’s no wonder Williams is kicking its competitors to the curb. We had TAP Blue, and the entire episode was covered by Williams. I give them a 10 out of 10!

Had an oil leak in our right PW545C. Textron tried to fix it. P&W told them what to do, but Textron said this was not the problem, and considered the issue fixed. However, the problem wasn’t resolved until P&W came to our hangar and fixed the issue in 3 hrs.

Have to consider that the GE Passport 20 is new to the Global 7500. Growing pains are certain, but GE has been responsive. However, the limited number of engines in use on the Bombardier platforms has been responsible for the limited availability of parts. I think that these issues will go away as the program develops.

We operate a Global 7500 with GE Passport 20 engines installed. I think onboard data logging allows for preventive maintenance before an AOG develops. I’d like to see an app to enable pilots to use engine data for more efficient maintenance event planning, like that used by Qantas & GE.
