| |
Summary of Problem: CH-47-02-03 was issued on 24 January 2002 requiring inspection of the Tie Bar Assembly and Rotor Tachometer. With regard to the tie bar inspections, the intent of the message was to inspect for cracked plates and deformation of washers only. Scores, scratches, buckling/separation of plates, and other minor installation damage are not grounds for failing this special inspection. The 1200 hour operating time special inspection will still be required. At the time the 1200 hour operating time special inspection is due, all tie bars that fail the inspection criteria of TM 55-1520-240-23, TASK 5-23.1.1 (H-47D/F), or TM 1-1520-252-23, TASK 5-31 (MH-47E), will require replacement. |
