Models named: AS332C, L, L1, Model SA330F, G, J. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
Model AS332C, L, and L1 and Model SA330F, G, and J helicopters, with tail rotor gearbox (gearbox), part number (P/N) 332A33-0001-all dash numbers, 330A33-0000-all dash numbers, 330A33-0011-all dash numbers (for AS332 models), or 330A33-9109-all dash numbers (for SA330 models), installed, certificated in any category. Note 1: This AD applies to each helicopter identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For helicopters that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
Compliance
Required as indicated, unless accomplished previously. To detect excessive angular play in the gearbox and to prevent failure of a gearbox, loss of tail rotor drive, and subsequent loss of control of the helicopter, accomplish the following: (a) Within 25 hours time-in-service (TIS) for any gearbox with 495 or more hours TIS, inspect each gearbox for play between the splines of the gearbox bevel gear and tail rotor driveshaft in accordance with the Accomplishment Instructions, paragraphs 2.A. through 2.B.4. of Eurocopter France Alert Service Bulletin No. 05.00.44 for the Model AS332 helicopters or No. 05.86 for the Model SA330 helicopters, both Revision 1 and both dated January 11, 2001. (1) Thereafter, reinspect the gearbox for play: (i) At intervals not to exceed 520 hours TIS, if the play measurement is 0.30 millimeter (mm) (0.0118 inch) or less for Model SA330 helicopters or 0.44mm (0.0173 inch) or less for Model AS332 helicopters, or (ii) At intervals not to exceed 100 hours TIS, if the play measurement is greater than 0.30mm and less than 0.65mm (0.0255 inch) for Model SA330 helicopters or greater than 0.44mm and less than 0.75mm (0.0295 inch) for the Model AS332 helicopters. (2) Before further flight, remove any gearbox if the play measurement is equal to or greater than 0.65mm for Model SA330 helicopters or 0.75mm for Model AS332 helicopters. (b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Regulations Group, Rotorcraft Directorate, FAA. Operators shall submit their requests through an FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Regulations Group. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Regulations Group. (c) Special flight permits will not be issued. (d) The inspections shall be done in accordance with Eurocopter France Alert Service Bulletin No. 05.00.44 for the Model AS332 helicopters or No. 05.86 for the Model SA330 helicopters, both Revision 1 and both dated January 11, 2001.
