Developed by the Yakovlev Design Bureau in the late 1970s and first flown in May 1981, it was built to replace the Yak-50. The aircraft is celebrated for its near-perfect neutral handling — achieved by aligning the engine thrust line, wing chord, and tailplane along a single straight axis — which allows it to fly upright and inverted with identical aerodynamic characteristics.\u003c\/p\u003e\n\u003cp\u003eThis archival collection brings together primary-source documentation issued by the Yakovlev Bureau and civil airworthiness authorities, covering the Yak-55 and its definitive Yak-55M variant. \u003cstrong\u003eThree documents in this collection are published under the Sicuro Publishing imprint\u003c\/strong\u003e  This is a \u003cstrong\u003eliving collection\u003c\/strong\u003e: additional documents will be added over time at no extra cost to existing purchasers.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eKey Technical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e Vedeneyev M-14P — 9-cylinder air-cooled radial, 360 hp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed:\u003c\/strong\u003e 476 km\/h (257 knots)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWingspan:\u003c\/strong\u003e 8.10 m (Yak-55M short-wing variant)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 7.07 m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmpty Weight:\u003c\/strong\u003e 640 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Factors:\u003c\/strong\u003e +9.0 G \/ −6.0 G structural limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoll Rate (Yak-55M):\u003c\/strong\u003e ≈ 340°\/sec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLanding Gear:\u003c\/strong\u003e Non-retractable high-strength titanium spring type\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirfoil:\u003c\/strong\u003e Fully symmetrical section — NACA 0018 root to NACA 0015 tip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eMain Variants\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eYak-55\u003c\/strong\u003e — The original standard version, built to provide stable, precise handling during complex modern aerobatic lines.

Its zero-dihedral, zero-incidence wing configuration neutralizes lateral stability entirely, allowing the pilot to lock the aircraft into knife-edge tracks without cross-coupling inputs. The engine thrust line, wing chord, and horizontal stabilizer are coplanar — the aircraft behaves as a pure aerodynamic cylinder, producing identical loop radii upright and inverted under equal G-loads. Because of its high power-to-weight ratio and immense control authority, it remains highly popular globally among advanced sport flyers and unlimited class competition aerobatic pilots.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eDocumentation Portfolio — 4 Primary Documents\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eYak-55 M Technical Manual\u003c\/strong\u003e — Full airframe and systems technical reference \u003cem\u003e(Sicuro Publishing edition)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYak-55 M Maintenance Schedule\u003c\/strong\u003e — Scheduled inspection and servicing intervals \u003cem\u003e(Sicuro Publishing edition)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYak-55 M Flying Manual\u003c\/strong\u003e — Pilot operating handbook, performance data, and procedures \u003cem\u003e(Sicuro Publishing edition)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eСамолет Як-55 — Руководство по летной эксплуации\u003c\/strong\u003e (Flight Operations Manual, Russian original, 1987) — 6 sections covering general data, operational limits, pre-flight checks, all flight procedures including 27 aerobatic figures, emergency procedures, and full systems description\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003cem\u003eThis is a living collection.
