Safety recommendation
FAA Urged to Investigate General Electric CF6-Series Engines
A safety review is recommended for CF6-series turbine engines due to design similarities.
The Federal Aviation Administration is being asked to evaluate the need for a directed safety investigation of all general electric cf6-series turbine engines. The request is based on similarities in design, manufacture, and maintenance, with the objective of verifying the established life limits for rotating parts of the fan modules and establishing appropriate cyclic inspection requirements for these parts. This recommendation was superseded by A-90-090.
