OPERATING COST & MAINTENANCE

xstol750_maint.jpg

Maintenance

The P-750 XSTOL is designed and manufactured with ease of maintenance in mind.  The maintenance cycle is every 150 hours or 1500 landings, whichever occurs first.  The average estimated time to complete a 150 hour check is approximately 25 - 30 hours.

Operating Costs

The costs below are indicative only and will depend upon local costs for fuel and labour and how the aircraft is being operated.

  1. Fuel - Typical cruising speed and altitudes will be achieved with a fuel burn of approximately 50 USG  or 200L per hour.
  2. Aircraft & Engine Inspection - The aircraft requires an inspection every 150 hours and this typically takes 25 man hours to undertake with a small allowance for consumables. Based on a labour rate of US$80/hour the maintenance is approximately US$16/flight hour including consumables.
  3. Airframe Maintenance - The airframe is very robust and needs little maintenance. Nothing needs to be replaced in the airframe until the aircraft has flown 39,000 hours. We suggest a $20.00 provision for future airframe maintenance.
  4. Reserves for engine and propeller overhauls: 
  • The Pratt and Whitney PT6A-34 engine requires an overhaul every 4,000 hours. Engine overhauls cost approximately US$200,000 = $50/hr.
  • The hot section needs an inspection every 1500 hours at a cost of US$20,000 = $13/hr.
  • A cost of US$2.50 per hour will cover the propeller overhaul every 3,000 hours, and the starter/generator replacement

Combining this, the total cost of US$240,000 over 4,000 hours making for US$60.00 per flight hour.
