Airworthiness Directive · Amendment 39-22991 · Turbine engine compressor section
Rolls-Royce Deutschland Ltd & Co KG Engines
This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) Model BR700-710A1-10, BR700-710A2-20, and BR700-710C4-11 engines as identified in European Union Aviation Safety Agency AD 2022-0110R1, dated November 22, 2023 (EASA AD 2022-0110R1).
The FAA is superseding Airworthiness Directive (AD) 2022-24-06 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model BR700- 710A1-10, BR700-710A2-20, and BR700-710C4-11 engines. AD 2022-24-06 required initial and repetitive visual inspections of certain low- pressure compressor (LPC) rotor (fan) disks and replacement of any LPC rotor (fan) disk with cracks detected. AD 2022-24-06 also allows for modification of the engine in accordance with RRD service information as a terminating action to these inspections. Since the FAA issued AD 2022-24-06, the manufacturer published updated service information and revised the engine maintenance manual (EMM) to provide instructions for an improved ultrasonic inspection method, which prompted this AD. This AD requires initial and repetitive visual inspections of certain LPC rotor (fan) disks and replacement of any LPC rotor (fan) disk with cracks detected and would allow modification of the engine as a terminating action to the inspections, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraphs (h) and (i) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, EASA AD 2022-0110R1.
(1) Where EASA AD 2022-0110R1 requires compliance from its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2022-0110R1 requires compliance from “29 June 2022 [the effective date of the original issue of this AD],” this AD requires replacing that text with “January 6, 2023 (the effective date of AD 2022-24-06).”
(3) This AD does not require compliance with paragraph (7) of EASA AD 2022-0110R1. The actions required by paragraph 7 of EASA AD 2022-0110R1 were included in AD 2022-26-02, Amendment 39-22280 (87 FR 78846, December 23, 2022), and for this AD may be used for informational purposes.
(4) This AD does not adopt the “Remarks” paragraph of EASA AD 2022-0110R1.
Although the service information referenced in EASA AD 2022-0110R1 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
