Cessna 310B OO-SEI
The Cessna Model 310 is a five-seat light twin-engine aircraft. It was the first Cessna to feature retractable tricycle landing gear and the first of the company’s designs to be tested in a wind tunnel. Production ran from 1954 to 1980, with 6 321 aircraft built across all variants. The 310B version was produced in 1958 only.

A notable feature of the early 310s was the tip-tank fuel system. All fuel was carried in the wingtip tanks, which designers believed would improve safety by keeping fuel away from the cabin. This system did cause some handling quirks and reduced cruising speed by about 16 km/h.

From 1958 until 1980, the École d’aviation civile (EAC) used this model for advanced training of future Sabena airline pilots.

Restoration  

When we recovered it from the Ostend technical school, the Cessna 310 had been stripped of a significant portion of its interior equipment. 
 
A grant from the Renard Fund made it possible to acquire the complete cabin interior of a Cessna 310 stored at a scrapyard in France. The removal of the required equipment took two days and was carried out by a team of two volunteers. The carpets, severely damaged by moisture, were reproduced identically by a professional upholsterer. The seats were fully dismantled, derusted, repaired, and restored. All remaining components were carefully refurbished before being reinstalled. 
 
Before reinstalling the interior, an essential step involved recreating the missing central section of the cabin floor. The windows, the rear bulkhead of the baggage compartment, the rudder pedals, interior paneling, and various other components were then reinstalled. 
 
The instrument panel was also restored, completed using instruments from the B.A.P.A. collection, and reinstalled in the aircraft. 
 
Two major components were still missing: the wingtip fuel tanks (“tip tanks”), characteristic of early-generation Cessna 310 aircraft, which significantly limited the availability of spare parts in Europe. Dianne Baginski, based in Ohio and owner of several early Cessna 310 aircraft, generously donated two fuel tanks and provided invaluable assistance in organizing their complex repatriation from the United States. 
 
Meanwhile, the second surface of the wings was sanded to remove corrosion and improve the overall aerodynamic finish.
