Compliance
If you performed a vibration check of the AGB before the effective date of this AD using Turbomeca S.A. MSB No. 292 72 0839, Version A, dated September 9, 2013, or Version B, dated November 25, 2013, or MSB No. 292 72 2849, Version A, dated September 9, 2013, or Version B, dated November 25, 2013; or during an engine shop visit per paragraph (e)(2) of this AD, you met the initial inspection requirement of paragraph (e)(1) of this AD.
Required actions
For the purpose of this AD, an “engine shop visit” is the induction of an engine into the shop for maintenance involving the separation of pairs of major mating engine flanges. The separation of engine flanges solely for the purpose of transportation without subsequent engine maintenance does not constitute an engine shop visit.
Unsafe condition
Comply with this AD within the compliance times specified, unless already done. (1) For all Turbomeca S.A. Arriel 1B, 1D, 1D1, 2B, and 2B1 turboshaft engines, perform a one-time vibration check of the AGB 41/23-tooth bevel gear meshing within 32 months of the effective date of this AD, as follows: (i) For all Turbomeca S.A. Arriel 1B, 1D, and 1D1 engines, except those engines with an AGB installed with a serial number (S/N) listed in the figure under paragraph 2.2. of Turbomeca S.A. Mandatory Service Bulletin (MSB) No. 292 72 0839, Version C, dated June 18, 2014, use paragraph 2.3.1. through 2.3.3. of Turbomeca S.A. MSB No. 292 72 0839, Version C, dated June 18, 2014, to perform the vibration check. (ii) You must also use Turbomeca S.A. Arriel 1 Technical Instruction (TI) No. 292 72 0839 and Turbomeca S.A. Arriel 1 TI No. 292 72 0840 to do the vibration check. (iii) For all Turbomeca S.A. Arriel 2B and 2B1 engines, except those engines with an AGB installed with an S/N listed in the figure under paragraph 2.2. of Turbomeca S.A. MSB No. 292 72 2849, Version C, dated June 18, 2014, use paragraphs 2.3.1. through 2.3.3. of Turbomeca S.A. MSB No. 292 72 2849, Version C, dated June 18, 2014, to perform the vibration check. Turbomeca S.A. MSB No. 292 72 2849 refers to Turbomeca S.A. Arriel 2 TI No. 292 72 2849 and to Turbomeca S.A. Arriel 2 TI No. 292 72 2850, which you must also use to do the vibration check. (iv) The reporting requirements in paragraphs 2.3.1.1.3., 2.3.2.1.3., and the requirement to return module M01 (AGB) to a Repair Center in paragraph 2.3.2.2.2. in Turbomeca S.A. MSB No. 292 72 0839, Version C, dated June 18, 2014, and in Turbomeca S.A. MSB No. 292 72 2849, Version C, dated June 18, 2014, are not required by this AD. (2) For all affected Turbomeca S.A. engines, during each engine shop visit after the effective date of this AD, perform a vibration check of the AGB 41/23-tooth bevel gear meshing. (3) If the AGB does not pass the vibration check required by paragraphs (e)(1) or (e)(2) of this AD, replace the AGB with a part eligible for installation.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
