Incident at WABUSH NL (CYWK) (Aerodrome, runway or taxiway shutdown, Aerodrome - power failure)

Summary

2001-02-16: Additional Information Aerodrome Safety February 12, 2001. It was determined during the course of checking cause of generator failure that there was an accumulation of fuel oil in the base of the diesel, which diluted the engine oil thus causing it to fail on low oil pressure. Probable cause would be leaking engine injectors. Unit will be checked out ASAP to determine actual cause. It was also determined during this incident that the batteries for the diesels are approximately 10 years old and in need of replacing. Two battery chargers were required to recharge the batteries for start-up at 8:10 pm. There were no flight disruptions
2001-02-19: Update from Aerodrome Safety February 19, 2001. It was discovered during an inspection of the bypass breaker that part of a latching mechanism on the side of the breaker was bent out of place, thus not allowing a component on the panel enclosure to perform it´s function properly. The latching mechanism was straightened, breaker racked into position, generator run up three times under full load. Went through all operational sequences normally.
