Adam Aircraft delivered one type to customers, the A500: a six-seat piston twin with one engine in the nose and one in the tail, a carbon composite fuselage and a pressurised cabin. The company closed after seven deliveries, and its jet, the A700, never went into series production.
An Adam A500 offered for charter is therefore a rare find. When a client names the type, we ask operators for one and, in the same reply, quote a piston twin or turboprop that is free near the departure airport.
Six-seat piston twin with push-pull engines on the centreline and a pressurised cabin. Only seven were built, so for a charter we usually offer a Seneca, a Navajo or a turboprop of similar size.
The idea behind the A500 was a small twin that is easier to fly than the usual ones. Its two Continental TSIO-550E engines of 350 hp sit on the fuselage centreline: one pulls a propeller at the nose, the other pushes one at the rear, and two booms carry the tail. If an engine stops, the aircraft does not swing to one side, as a twin with engines on the wings does.
| Model | Passengers | Range | Cruise speed | Cabin height | Baggage | Hourly rate |
|---|---|---|---|---|---|---|
| A500 | 3-5 | 1,652 km | 410 km/h | 1.30 m | 0.70 m³ | EUR 1,000 |
The A500 figures are published data for the type. The hourly rate is our price model for a piston twin of this size; an offer for the A500 itself, if one is free, can differ.
Passenger charter needs an operator with an AOC, and most A500s belong to private owners. With the manufacturer gone there is no factory support, so parts and maintenance depend on a few workshops that know the type. For an operator that is a serious hurdle, and offers for this exact aircraft come up very rarely in Europe.
Clients who ask for an Adam A500 usually want two engines, a cabin for up to five and a modest price. These common types from Piper, Beechcraft and Daher give that:
| Model | Passengers | Range | Cruise speed | Cabin height | Hourly rate |
|---|---|---|---|---|---|
| Seneca | 4-6 | 1,611 km | 370 km/h | 1.06 m | EUR 1,000 |
| Navajo | 5-7 | 1,875 km | 383 km/h | 1.30 m | EUR 1,300 |
| King Air 90 | 4-7 | 2,334 km | 504 km/h | 1.45 m | EUR 2,000 |
| TBM 940 | 4-5 | 3,204 km | 611 km/h | 1.22 m | EUR 2,000 |

Thanks to its pressurised cabin the A500 can climb above part of the cloud and turbulence, which unpressurised twins cannot. Toilet and galley depend on the individual aircraft, and the payload is small. In practice this class works for legs of up to about two hours with two to four people:
Longer legs, five people with suitcases or a fixed meeting time in winter call for a turboprop or a light jet. As twins, the A500, the Seneca and the Navajo are not bound by the EU limits on single-engine aircraft flying passengers at night or in cloud, but in icing a small piston aircraft without approved de-icing stays on the ground.

The tables give EUR 1,000 per flight hour for the A500 class and the Seneca. The Navajo costs EUR 1,300 per hour, and the King Air 90 and the TBM 940 cost EUR 2,000, always for the whole aircraft with pilot and fuel. The block below lists the hourly floors for turboprops and jets; small piston twins cost less than the turboprop floor.
Flight time alone does not set the price of a short leg. Each quote carries the operator's minimum charge, the flight from the aircraft's base and the fees of both airports, so Zurich - Lugano takes 0:55 h and costs from EUR 4,000, four times the hourly rate. On Madrid - Palma, 1:52 h from EUR 5,000, the fixed part weighs less.
The A500 prices below are model calculations for a piston twin of its size. The type is rarely offered, so the quote you receive may well be for a Seneca, a Navajo or another aircraft of the same class.

| Munich - Venice (VCE) | Navajo | 320 km | 1:22 h | EUR 5,000 |
| Geneva - Nice (NCE) | King Air 90 | 300 km | 1:10 h | EUR 6,500 |
What goes into a quote:
Empty Legs on the A500 itself practically never appear. On other small twins and turboprops they come up now and then, mostly on returns from the islands and the Riviera, and can be 40-65 % below a normal charter. The operator fixes the date and route and may cancel the leg if the aircraft is sold for a full trip.

For a quote we need:
Each offer names the type, the operator and the year of the aircraft. Before the flight you sign a contract with the price, the payment terms and the operator's cancellation rules.
We say plainly when an A500 is out of reach on your date and send the nearest twin or turboprop that does the same job, with its cabin, payload and approvals checked. You get a firm option instead of waiting for an aircraft that may not be available.

Only if an owner flies it under an operator's AOC, and with seven aircraft built such an offer is very rare. We check for one and quote a Seneca, a Navajo or a turboprop at the same time.
Zurich - Lugano costs from EUR 4,000 and Madrid - Palma from EUR 5,000 for the whole aircraft one way, with pilot and fuel. Fees, taxes and any positioning flight are extra.
No. It has two piston engines driving propellers, one at the nose and one at the tail. The jet version, the A700, never entered series production.
There are five passenger seats, but with full tanks only about 120 kg remain for people and bags. If all five seats are filled, only fuel for a short hop fits within the weight limit.
The operator's minimum charge, the flight from the aircraft's base and the airport fees are the same on every leg. On a longer flight they are spread over more hours.
The King Air 90, because it is a pressurised twin with a similar number of seats. For a lower price the Seneca or the Navajo do the same trips without pressurisation.
Practically none. Other small twins and turboprops have them now and then, at 40-65 % below a normal charter, on the date and route the operator sets.
