What to do
Affected operators must revise the airworthiness limitations section of their existing engine maintenance manuals and approved continuous airworthiness maintenance programs to incorporate the reduced life limit of 23,800 flight cycles for the left-hand rear mount link assembly. These revisions must be completed within 180 days after the directive's effective date. Operators should coordinate with maintenance and engineering teams to implement these changes promptly.
Summary
The Federal Aviation Administration's Airworthiness Directive 2022-02-18 is a final rule addressing General Electric Company CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6-80C2A5, CF6-80C2A5F, and CF6-80C2A8 turbofan engines equipped with left-hand rear mount link assembly part number 1846M23G01. This directive mandates revisions to the airworthiness limitations section of the engine maintenance manual and the operator's continuous airworthiness maintenance program to reflect a reduced life limit for the specified engine part. The directive aims to enhance safety by preventing potential engine mount failures.
What changed
This new airworthiness directive reduces the life limit of the left-hand rear mount link assembly, part number 1846M23G01, from 50,000 flight cycles to 23,800 flight cycles. It requires operators to update the airworthiness limitations section of the engine maintenance manual and their approved continuous airworthiness maintenance programs accordingly. This change is based on updated stress load analyses during take-off that were not considered during original certification.
Why it matters
This directive is critical for aviation professionals because it addresses an unsafe condition that could lead to engine separation from the aircraft, posing a severe safety risk. Operators, maintenance, and compliance teams must ensure that maintenance schedules and life limits are updated to prevent potential failures. Adhering to this directive helps maintain regulatory compliance and ensures continued airworthiness of affected engines.
