Fuji T-5
The Japanese navy has been a long user of the Beechcraft T-34 Mentor, that was locally produced. Fuji made several own developments of this aircraft, of which the T-5 is among the latest iteration. The aircraft still has some elements that trace back to the T-34, in particular the straight wings with a slightly swept inboard section, and the landing gear, of which the nearly triangular main gears doors are very typical. The fuselage is wider than that of the T-34, and more comparable to that of the Fuji KM-2. It sits the instructor and student pilot side-by-side under a bubble canopy with two bow frames that slides open to the back. The aircraft is powered by a turboprop engine in the nose, with an air intake under the prop spinner, and exhausts on both lower sides of the cowling. Finally, the T-5 has a slightly swept vertical stabiliser, with a triangular dorsal fin in front.
Confusion possible with
SIAI-Marchetti SF260
Like the T-5 the SF260 is a side-by-side trainer with a single propeller up front. Most versions are powered by a piston engine, but the are also turboprop versions. The SF260 also has a bubble canopy, but with a single bow frame. Moroever, it lack the typical triangular main gear doors. Finally, the SF260 has tip tanks.
Fuji T-7
In essence, the Fuji T-7 is the tandem cockpit version of the T-5, with a canopy similar to that of the Beech T-34. It also, has a narrower fuselage, but retains all of the other T-5 features.
Beechcraft T-34 (Turbo) Mentor
Being the ultimate pedigree holder of the T-5, the Beech T-34 is mentioned here as well. but actuall, it looks more like the T-7 than the T-5 because the T-34 has a tandem canopy. Additionally, the T-34 has a straight vertical stabiliser.
