Aircraft sync systems have been installed on your aircraft for both pilot and passenger convenience. Speed and/or relative propeller phase are naturally affected by normal flight conditions and require adjustment either automatically or manually.
Some pilots manage these drifts manually by nudging levers to bring speeds back in alignment. But the benefits of having your automatic sync system operating is reduced pilot workload, and consistently happier passengers.
Even a fraction of a single RPM difference between props is annoying to your passengers. If your aircraft is installed with a phasing system, a non-working sync system is neither controlling speeds nor relative phase, which can maintain ambient noise and vibration at their lowest levels.
Some aircraft require proper operation of the sync system as it is included on their minimum equipment list (MEL). Often aircraft being sold require all systems to be operational by the new owner.
Systems that have been out of service for some time can require additional parts and effort to bring back proper operation, so it is better to solve your sync system problems sooner, rather than later.

Your test box operated perfectly and identified the problem for us to repair.
Your (prop sync system) troubleshooting kit it is absolutely fantastic. Saved us a lot of time. Thank you much for your help!
“The TB2-1 tester was very helpful in finding the problem which was a grounded wire on the RE sensing circuit. Once fixed, we ran through the operational tests using the tester and the system worked well.”
“Your Type II Test Unit (TB2-1) works great !! Everything seems to be in sync now on the aircraft (pun very much intended). Thanks for all your help !!!”
“Thank you again for the great help, and the TB2-1 tester. It made my life easy!!”
“We had a customer come in with a 421B with a prop sync problem. He had been to several shops to have his prop sync repaired without any luck. Our customer mentioned that he saw Prop Sync Solutions on the internet, so I followed up and called. Being always concerned with completing jobs timely, I was impressed with how accessible Mark was. He was always quick to return calls and emails. I rented his Type 1 test box,and with his support was able to nail down the faulty component immediately.
Prop syncs can really soak up labor troubleshooting faults, and having a company like Prop Sync Solutions is a real benefit. I highly recommend them to anyone with a prop sync or prop synchrophaser problem”
