Applicability: Model EC120B helicopters, serial numbers 1001 through 1278, inclusive, 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 within 90 days, unless accomplished previously.
To prevent an object from sliding between the canopy and the cabin floor, loss of yaw control, and subsequent loss of control of the helicopter, accomplish the following:
(a) Install front and side covers (protections) to protect the yaw control in accordance with the Accomplishment Instructions, paragraph 2.B., Eurocopter Alert Service Bulletin No. 67A005, dated July 30, 2001 (ASB), except the correct reference to the Aircraft Maintenance Manual in subparagraph 2.B.2 of the ASB is 20-10-00, 3-8. If the helicopter has flight controls at both the pilot and co-pilot stations, front and side protections are required at both stations.
