The 9 August uncontained failure of the left inboard Honeywell LF507 engine on a Swiss International Air Lines BAE Systems Avro RJ100 en route from Amsterdam to Zurich peppered the neighbouring (No 1) power unit with debris, generating a No 1 engine fire warning (Flight International, 17-23 August). The crew shut down the No 1 and diverted to Frankfurt, landing safely. Honeywell says it cannot comment because the incident is subject to an inquiry by German accident investigation unit BFU. BFU has not released any information. The US Federal Aviation Administration has been working to reduce LF507/502 uncontained failure vulnerability.
