YR-AHA was previously Papana's Bellanca. I've found this:-
Alex Papana, a renowned Rumanian acrobatic pilot who performed at air shows with the German-built Jungmeister, wanted a fast, single-seat airplane for his personal use. Once again, it was Giuseppi Bellanca who was approached to build the airplane. Meetings with Papana concluded the airplane would be a single-seat, three-engined monoplane with retractable landing gear and cantilever wing. The two outboard engines were 250 hp supercharged inverted Menascos and the center engine was a 420 hp supercharged V-12 Ranger. All three engines were equipped with controllable-pitch propellers.
The airplane was registered in Rumania as YR-AHA and test flown by Papana from the Bellanca Airfield in New Castle, Delaware, USA in 1937. Alex Papana was a superb acrobatic pilot who could put his Jungmeister through any acrobatic maneuver of the day with precision. However, he did not have a history of flying fast, supercharged airplanes with controllable pitch propellers. On his first test flight from Bellanca Airfield, he over-boosted the engines and overshot the runway on landing. Fortunately, the airplane was not damaged, except for burned-out engines.
Art Chester was flown in from the Menasco factory, and he overhauled the engines at the Bellanca factory. The incident caused a flap between Bellanca and Papana which caused the latter to cancel the order. Giuseppe Bellanca harbored deep feelings about his airplanes. If a pilot abused a Bellanca, and Giuseppe heard about it, it was a certainty the pilot would hear from him.
Giuseppe Bellanca then decided to prepare the airplane for the 1938 Bendix cross-country air race and reregistered the airplane in the USA as NX2433. Although off to an excellent start, pilot Frank Cordova was forced to land in Cleveland, Ohio with a burnt-out Menasco. The engine was so badly damaged it had to be removed from the airplane and weights installed to balance the airplane. Cordon flew the airplane back to Delaware on the two remaining engines for repair.
By 1939, the airplane was ready for another attempt at winning the coveted Bendix cross-country event. Art Bussy piloted the Bellanca racer to a second place victory behind a new military Seversky fighter The Seversky was the first in a series of military fighters which would evolve into the mighty P-47 Thunderbolt used in WWII. Bussy flew from Los Angeles, California to Cleveland in 8 hours and 21 minutes averaging 244.486 mph (393.4621 kmh). After refueling in Cleveland, Bussy flew on to New York, New York, to finish. Second place prize money was a mere $5,800, which barely paid the operating costs for the race.
After this historic flight, the Bellanca racer was stored in a hangar on Bellanca Airfield and never raced again. It was reported in a 1968 issue of Sport Flying that the airplane was sold to the Argentine Government. This is the only information uncovered concerning the fate of this remarkable airplane.
