Cessna; Model T210M; Alternate Air-Door Catch Magnet; ATA 7160

The engine alternate air door is held closed with a magnetic latch (P/N 1250938-8). The magnetic latch has two small plates bonded to the magnet that make contact with the alternate air door. One of the steel plates debonded due to age and vibration. The plate was ingested into the turbocharger. The turbo was destroyed causing a total loss of boost and a return landing. Metal from the turbo passed through the induction and oil systems causing major damage.

The submitter stated they have found two other T210’s with latches ready to fail. Cessna has designed a new latch (P/N C100200) that will not allow any parts to fall into the induction system.

A search of the FAA Service Difficulty Reporting Program data base revealed five additional occurrences from 1984 through 1993. Two of the five latches were ingested into the turbocharger, destroying it.

Part total time: 2,304 hours.
