            Requirement: Inspect TCM P/N 642668, welded turbocharger inlet assembly for cracks especially in the weld joint just above the turbine inlet temperature boss.

            Note 1: FAA AD 89-24-03 Amdt 39-6386 refers.

            Note 2: To assist with identification, the 646795 assembly has 2 ribs approx 6 mm (0.25 inches) in height, 2.5 mm (0.1 inches) in width and 53 mm (2.1 inches) in length on top of the turbocharger mating flange.

            Note 3: If P/N 642668 is not installed no further action is required.
