ENGINES


In the worst case scenario, the cost of replacing pre-fi lters and deionization components will run $200 to $700 per year, depending on the size of the distiller. Maintenance of the distiller itself is limited to the infrequent replacement of a heating element. The USCG has 35 distillers that have been in service since 2009, and the mechanics at the Coast Guard bases have replaced a total of 29 heating elements since inception. The initial cost of the distiller depends on the size required


in terms of the amount of distilled water desired for daily use. A small unit that will produce 12 gallons during a 24-hour period and has internal storage for 25 gallons is suffi cient to provide for a daily turbine rinse for four turbines (based on 4.5 gallons per rinse). These units cost on the order of $5,000 to $8,000, depending on the pretreatment and distiller options required.


Conclusion When I fi rst started in the engine overhaul business doing my apprenticeship in the engine overhaul shop, I had the good fortune to move over to the customer support department as a tech rep for the then Allison 250 (now Rolls-Royce) turbo- shaft engines. One of my Hawaiian customers consistently ran all of his components, engine included, to TBO (3,500 hrs with a N1/ Ng wheel replacement at 1,750 hours). This was contrary to what his fellow operators were doing. Not only did he always make TBO, his overhauls were always on average 15 to 20 percent lower cost than the rest of the Hawaiian operators. On one of my visits to his facility, I had asked how he managed to get his equipment to TBO consistently. He said rain water! He would collect the near-daily rain water and use it after the last fl ight every day to keep his helicopter clean. “Pure water makes the diff erence,” he told me with a wink and a nudge. What better source than from naturally-distilled rain water? It was free and it worked!

RELIABILITY MATTERS


Even if the battery is providing engine starting power it is not a sign that it has enough capacity for essential power. The minimum lead acid battery capacity to return to service (AC 43.13-2B) as recommended by both Concorde Battery Corporation and the FAA is 85%.
