Abstract

<strong>Description of Driving Event:</strong> <br>On Monday, April 15, 2002 at approximately 5:45 PM the following incident occurred on the Stennis Space Center A1 test stand, level 5 upper engine work deck. <br>Subsequent to the removal and replacement of a High Pressure Fuel Pump the upper engine deck extension piece was rolled away from the main upper engine deck with the pump lifting/handling device still on the upper engine deck extension piece. The pump lifting device fell off the upper engine deck pinning a quality inspector between it and the upper engine deck handrail. The arm of the pump lifting/handling device was moved enough for the employee to be moved away and the deck was cleared. The device was secured in the as-rested position and the deck was cordoned off. The employee was able to walk on his own to inside the test stand. The employee was transported to a local hospital for an examination as a precaution. Photographs were taken of the area and equipment involved (contact Michael McDaniel, 228-688-2233). <br>An investigation/preventive action team was formed by management on the morning of Tuesday, April 16, 2002 to investigate, find the root cause, and make corrective action recommendations. <br>The A1 test stand had been recently reconfigured from a previous test program to a different test program after a 5 year period. The test team had moved from the A2 test stand to the A1 test stand. The test team did not feel this was a factor due to the similarities between the two test stands. The normal configuration for all pump removals is to use a roll-around work deck extension piece secured to the main work deck via turnbuckles.
