Is there a single engine turbine airplane that wieghs over 12,500 pounds??
Fred Ayres in Albany, GA developed a single propellar twin turbine aircraft called the Loadmaster LM200...well over 12,500 lbs. Don't know if this would qualify for single or multi engine. FedEx ordered 50 before Ayres Aircraft went into bankruptcy. Don't know if the aircraft will ever get produced.
Since Ayres declared bankruptcy last November, development of the Loadmaster LM200 has slowed considerably, although the FAA recently issued a notice of proposed special conditions regarding certification of the aircraft. These flight-test special conditions, Ayres certification manager Jim Hill told AIN, concern testing of the airplane with its Fadec- controlled propulsion system unit failed and one engine inoperative. The Loadmaster is designed to be powered by two CTP800-4T turboprop engines driving a single Hamilton Standard propeller via a GKN Westland combining gearbox.
According to the FAA, “This airplane will have novel or unusual design features associated with centerline thrust. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.”
Other special conditions, relating to fire protection in the Loadmaster’s cargo and baggage compartments, were issued in final form by the FAA in early April. These conditions specify the certification provisions the Loadmaster must meet, in addition to the requirements in Part 23, when operating in all-cargo and combination cargo/ passenger (combi) configurations.
Despite this progress and the limited work being done on the Loadmaster prototype in Albany, Ayres said it is extremely difficult to estimate first flight and certification dates for the airplane until Ayres is restructured.
