(The following starter description occurs on a Cessna 172S aircraft with a Lycoming IO-360-L2A engine installed.)

“This starter pinion gear failed,” states the submitter. “Pieces of the gear jammed the starter motor and damaged the ring gear. This is the second occurrence of this incident on this aircraft. We also maintain another 172S that had this problem and same damage two times. I have spoken with Lamar about this and they mention there has been a problem in the past. In all cases (except this last one) teeth have broken off the ring gear. The current incident has only damaged the ring gear teeth.” (The SDRS data base returns seven reports on the Lamar starter.)

Part Total Time: 266.0 hours.
