Resumo
The Federal Aviation Administration (FAA) proposes to adopt a new airworthiness directive (AD) that is applicable to Rolls-Royce plc RB211 Trent 875, 877, 884, 892, 892B, and 895 series turbofan engines. This proposal would require reapplication of dry film lubricant to low pressure compressor (LPC) fan blade roots. This proposal is prompted by an aborted take-off resulting from LPC fan blade loss. Since this event, four additional cracked LPC fan blade roots have been reported. The actions specified by the proposed AD are intended to prevent LPC fan blade loss, which could result in an uncontained engine failure and possible aircraft damage.
