| Title | Part 21 - Cracked Spray Tip on Emd Fuel Injector |
| Event Description | The following is a summary of information received from Engine Systems, INC (ESI) via facsimile:
The basic component, a fuel injector, P/N 5229250, S/N R2200, was sent to ESI for failure analysis and the spray tip was found to have a through wall crack. Inspections determined the fuel feed holes in the body of the spray tip were incorrectly drilled, resulting in one of the holes not properly penetrating the reservoir. A cracked spray tip would inhibit proper combustion of fuel within the corresponding power cylinder which could affect the carrying capability of the diesel engine. This could impact the operability of the diesel engine, thereby, preventing the emergency diesel generator set from performing its safety-related function. It is the belief of ESI that the extent of condition is limited to the single spray tip. Based on the age of the tip (repair kit purchase order (PO) date is 2001), if other tips contained the same discrepancy, it is highly likely they would have been detected or replaced. There were 20 tips in the same batch as the failed spray tip. The end user of the PO is Nine Mile Point. ESI suggests that the customer perform an inspection on the remaining 19 injectors. ESI has discontinued the affected injector repair kit. |
