The FAA's summary their words, unchanged

The FAA is adopting a new airworthiness directive (AD) for all General Electric Company (GE) CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6- 80C2A5, CF6-80C2A5F, and CF6-80C2A8 model turbofan engines with an installed left-hand rear mount link assembly, part number (P/N) 1846M23G01. This AD was prompted by the manufacturer reducing the life limit for the affected left-hand rear mount link assembly. This AD requires revising the airworthiness limitations section (ALS) of the existing engine maintenance manual and the operator's existing approved continuous airworthiness maintenance program (CAMP). The FAA is issuing this AD to address the unsafe condition on these products.

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2022-02-18 General Electric Company: Amendment 39-21915; Docket No. FAA-2021-0949; Project Identifier AD-2021-00115-E. (a) Effective Date This airworthiness directive (AD) is effective February 25, 2022. (b) Affected ADs None. (c) Applicability This AD applies to General Electric Company (GE) CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6-80C2A5, CF6-80C2A5F, and CF6-80C2A8 model turbofan engines with an installed left-hand rear mount link assembly, part number (P/N) 1846M23G01. (d) Subject Joint Aircraft System Component (JASC) Code 7120, Engine Mount Section. (e) Unsafe Condition This AD was prompted by a report from the manufacturer on an updated analysis of stress loads during take-off, which revealed a stress increase with take-off phase loads that were not included at certification. The FAA is issuing this AD to lower the life limit of the left-hand rear mount link assembly and prevent the failure of the engine mount system. The unsafe condition, if not addressed, could result in separation of the engine from the airplane and loss of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Within 180 days after the effective date of this AD, revise the airworthiness limitations section of the existing engine maintenance manual, and the operator's existing approved continuous airworthiness maintenance program, by reducing the life limit of the left-hand rear mount link assembly, P/N 1846M23G01, from 50,000 flight cycles (FCs) to 23,800 FCs.
