The FAA's summary their words, unchanged
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Corporation (RRC) AE 2100D3 model turboprop engines. This AD requires revising the airworthiness limitations section (ALS) of the RRC AE 2100D3 Maintenance Manual and the operator's approved continuous airworthiness maintenance program. This AD was prompted by a report of a propeller gearbox (PGB) development test in which high vibration occurred due to a fatigue crack that initiated in the propeller shaft. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is issuing this AD to prevent loss of the propeller. The unsafe condition, if not addressed, could result in damage to the engine and damage to the airplane. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Required Actions \n\n\n\t(1) Within 30 days after the effective date of this AD, revise the RRC AE 2100D3 Maintenance Manual (''the Manual'') and the operator's existing approved continuous airworthiness maintenance program by inserting: \n\t(i) Task 05-11-00-800-801, dated June 20, 2018, into Airworthiness Limitations System Description Section-801; and \n\t(ii) Task 05-12-11-800-802, dated June 1, 2020, into Propeller Gearbox System Component Life Limits Systems Description Section-802 in the Manual. \n\t(2) Thereafter, except as provided in paragraph (h) of this AD, no alternative replacement times or structural inspection intervals may be approved for this PGB shaft and carrier assembly. \n\n(h) Alternative Methods of Compliance (AMOCs) \n\n\n\t(1) The Manager, Chicago ACO, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
