NOTE: This determination may be made by lubricating the uplock rollers and verifying that grease passes between the inner and outer races. B) Within the next 300 hours' time in service after the effective date of this AD, install hollow zerk-ended mounting bolts on the uplock rollers in accordance with Beech Service Instructions No. 0448-211 or any FAA-approved equivalent. C) Within the next 300 hours' time in service after the effective date of this AD, and thereafter at 100 hour intervals, lubricate the uplock mechanism in accordance with Beech Service Instruction No. 0448-211. This AD supersedes AD 72-17-02 (Amendment 39-1501).
