Aircraft; Procedure
The aircraft in question came in for a dead left magneto which failed in flight. We troubleshot and determined it was in fact a dead left magneto. We removed and replaced the left magneto with a factory rebuilt magneto. Ops checked everything fine. Mag drop was perfect. The pilot ran it as well. No issues. He loads up his passenger; and they take off. Well; the right-hand magneto fails on takeoff; resulting in him turning back and landing at the airport. Back in (Month) 2020 that right hand magneto failed and we replaced it with a factory rebuilt magneto as well. I am writing this to see what can be done about these factory rebuilt magnetos. I feel they are failing too soon. Only 100 hours in between failures. If the left magneto would've held out and failed at the same time as the right hand just did; it could've been a catastrophic failure and maybe even loss of lives.
Technician reported multiple magneto failures of factory rebuilt magnetos on the same PA-32 aircraft.
