Robinson R66 Helicopter OVERHAUL PRICE

 The following Robinson R66 Helicopter overhaul prices are effective for all aircraft arriving at the LHD factory ready for overhaul and apply to properly maintained, undamaged R66 helicopters without excessive corrosion, and still in airworthy condition. Upon receipt of the aircraft, including all parts, logbooks, signed work authorization, and a 50% down payment, the aircraft will be disassembled, inspected, and reassembled. During overhaul, all fatigue-life-limited components with less than 2000 hours remaining are replaced. All engines are overhauled per the current rolls-Royce overhaul manual by a Rolls-Royce Authorized Maintenance Repair & Overhaul Center. We ensure all aircraft service and maintenance is to Robinson Factory Requirements. The overhaul price includes the following:
