Main Landing Gear Cross Tubes 9/95 DM

Applicability: All Bell and Agusta Bell 206A, 206B and 206C series.

Requirement: Remove from service, and permanently mark as unserviceable, the cross tube assemblies as follows:

a. BHTI P/Nos. 206-050-107, 206-050-119, 2060-50-134, 206-050-157, 206-050-

c. unidentified assemblies.

Note: FAA AD 95-11-14 and Bell Alert Service Bulletins 206-94-78, 206-94-81, 206- 94-82, 206-94-83, 206L-94-93, 206L-94-97 and 206L-94-98 refer.

Compliance: Prior to 30 September 1995.

Background: A number of Bell 206 cross tubes have failed, or nearly failed, in Australia and overseas. Some failures have resulted in roll-overs causing serious injury and extensive damage. The cracking that causes failure is unpredictable and hard to detect before safety is compromised.

Amendment 1 aligns the requirements of the Australian Directive with those of the FAA by deleting the eddy current inspection, deleting reference to an approved inspection scheme, and mandating a later terminating action compliance date.
