The True Operating Cost of Sikorsky S-76

The Sikorsky S-76 is an industry-standard twin-engine commercial helicopter offering 14-seat capacity, exceptional reliability, and multi-mission capability. Plan for $180,000–$220,000 annually in operating costs at 100 flight hours, or $1,800–$2,200 per hour. The S-76 dominates offshore, corporate, and emergency services with unmatched performance, safety, and operational flexibility.

Operating-cost worksheet

Defaults are round assumptions, not a shop quote. AOPA’s worksheet splits fixed costs (insurance, hangar, the annual), direct costs (fuel and maintenance), and a reserve (overhaul cost divided by hours to TBO). Their old teaching example used half the hourly fuel bill as a maintenance starting point. Type your own gph and prices.

Stop dividing one year’s costs by too few hours

The expensive mistake on a Sikorsky S76 is to take insurance, hangar, and an annual, divide by 80 or 100 hours, and call the result the cost of flying. Those bills arrive if you fly or not. AOPA’s operating-cost worksheet treats them as fixed costs, then adds direct costs that do move with hours: fuel, oil, and maintenance. A reserve for the engine or propeller is a third bucket, optional in their sheet and not optional in real life if you intend to keep the aircraft through an overhaul. The worksheet on this page follows that split. Any annual dollar range printed higher up on this page, if it does not cite an invoice or AOPA, is an illustration. Do not repeat it as a quote.

Fuel is a multiplication, not a rumor

AOPA’s instruction is price per gallon times gallons per hour. The gallons per hour belong to the way you actually fly the Sikorsky S76, not to the brochure cruise at the most flattering altitude. Oil is the same idea: price per quart times quarts per hour. Type both into the worksheet. If you do not know burn, leave a conservative guess and replace it after five tanks of your own notes. A blog’s “cost per hour” that hides the burn and the fuel price is not usable, because you cannot tell which assumption broke.

The maintenance starting point AOPA actually published

For a first pass, AOPA equates routine engine and airframe maintenance, on an hourly basis, to about half the hourly fuel and oil bill, and says to adjust it once you have your own invoices. The checkbox on the worksheet does that and nothing fancier. Turn it off and type a maintenance figure when you have one. A separate AOPA line for avionics is 5 percent of the avionics’ replacement value per 500 hours. That is a starting point from their sheet, not a prediction that your Sikorsky S76 panel will fail on schedule. Unsupported radios cost more than that formula, because the fix is often a replacement, not a repair.

The overhaul reserve is a division

AOPA’s method is the shop’s overhaul or remanufacture price divided by hours left until the published TBO, not divided by the full TBO if the engine is already mid-time. Their sheet walks through a Cessna 172 example: $17,000 over 2,000 hours is $8.50 an hour, while a $27,000 reman with 900 hours left is $30 an hour. Those dollars are the example in the article, and they are not a 2026 quote for a Sikorsky S76. The arithmetic is what you copy. Propeller overhaul, in the same AOPA sheet, is penciled at about $0.25 an hour for a fixed-pitch prop and about $1 an hour for a constant-speed prop, with more for a three-blade. Treat those as historical placeholders and ask a prop shop.
