Airworthiness Directive · Amendment 39-22533 · Starter- generator
Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. Model A119 and AW119 MKII helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model A119 and AW119 MKII helicopters. This AD was prompted by a report of an electrical failure of a starter-generator caused by a ruptured drive shaft. This AD requires visually inspecting the drive shaft of an affected starter-generator and depending on the results, performing a dye penetrant inspection. Depending on the results of the dye penetrant inspection, this AD requires replacing the starter-generator, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). 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: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency EASA AD 2022-0148, dated July 14, 2022 (EASA AD 2022-0148).
(1) Where EASA AD 2022-0148 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2022-0148 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(3) Where paragraph (1) of EASA AD 2022-0148 states to, “inspect the drive shaft;” for this AD, replace that text with,” inspect the drive shaft for misalignment and a crack.”
(4) Where the service information referenced in EASA AD 2022-0148 specifies to proceed with subsequent procedures if there is misalignment or if the alignment is not clear; for this AD, proceed with those subsequent procedures before further flight.
(5) Where the service information referenced in EASA AD 2022-0148 states, “with reference to Annex A, perform a liquid penetrant inspection of the drive-shaft, in order to detect the presence of eventual cracks;” for this AD, replace that text with “With reference to Annex A, perform a dye penetrant inspection of the drive-shaft in order to detect any cracks.”
(6) Where the service information referenced in paragraph (1) of EASA AD 2022-0148 specifies contacting LH [Leonardo Helicopters] spare management to send a starter-generator directly to an authorized repair station for repair and sending the starter-generator to an authorized repair station for repair, this AD does not require those actions.
(7) Where paragraphs (2) and (4) of EASA AD 2022-0148 state, “Part II of the ASB;” for this AD, replace that text with, “AMP Data Modules 19-A-24-30-04-00A-520A-A, Starter Generator-Remove Procedure and 19-A-24-30-04-00A-720A-A, Starter Generator-Install Procedure, each Issue 001 and dated May 24, 2021. Except where AMP Data Module 19-A-24-30-04-00A-520A-A Starter Generator-Remove Procedure specifies discarding parts, for this AD, remove those parts from service.”
(8) This AD does not require paragraph (3) of EASA AD 2022-0148.
(9) This AD does not adopt the “Remarks” section of EASA AD 2022-0148.
Although the service information referenced in EASA AD 2022-0148 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
