Applicability*9
AS332L2 helicopters, with main rotor head drag damper, part number (P/N) 332A311980-02, having elastomeric bearings P/N J19084-4, 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 (c) 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 delamination of an elastomeric bearing that could result in failure of a main rotor head drag damper (damper) and subsequent loss of control of the helicopter, accomplish the following: (a) Within 10 hours time-in-service (TIS), inspect each damper, P/N 332A311980-02, for a tear, crack, or bonding separation in the elastomer as follows: (See Figure 1.) (1) Separate the elastomer in Area A (outside reinforcement) and in area B (inside reinforcement). (2) If a tear, crack, or bonding separation is found, replace the damper with an airworthy damper. Note 2: American Eurocopter Master Servicing Recommendation (PRE) 05.99.00, rush revision date-code 97-46, and the Aircraft Maintenance Manual Nos. 05.21.00.213 and 05.21.00.213.001 pertain to the subject of this AD. (b) Thereafter, prior to the first flight of each day or at intervals not to exceed 20 hours TIS, whichever occurs first, perform the inspection in paragraph (a). If a tear, crack, or bonding separation is found in the elastomer, replace the damper with an airworthy damper.
