Fokker 50 (F-27 Mk 50) — Primary Technical Documentation Collection

The Fokker 50 stands as one of the most technically refined regional turboprops ever produced — a direct aerodynamic evolution of the legendary Fokker F27 Friendship, re-engineered from the ground up with composite structures, advanced propulsion, and a hybrid mechanical-electronic flight control suite. This collection brings together the primary-source documentation that defined, certified, and sustained the F-50 throughout its operational life under EASA and FAA oversight.

Managed and issued by Fokker Services B.V. / Fokker Services Group, these documents represent the authoritative engineering and operational record of the aircraft — from its aerodynamic design philosophy to its final structural aging inspections.

Propulsion — Pratt & Whitney Canada PW125B / PW127B

The F-50 is powered by twin PW125B engines rated at 2,500 shp (1,864 kW) each, or optional PW127B units at 2,750 shp (2,050 kW). Power management is handled by dual Electronic Engine Control (EEC) units operating a unique single-lever system that coordinates propeller pitch and engine power simultaneously via six-bladed Dowty Rotol composite propellers. The flight-idle stop system and mechanical ground-idle locks are documented in the engine technical training papers included in this collection.

Aerodynamic & Structural Design Notes

The F-50 incorporates SABCA-designed high-aspect-ratio wings with upturned Fowler flaps and aerodynamic nacelles. Composite materials (aramid and carbon fiber) are used in fairings, trailing edges, and the dorsal fin. The horizontal stabilizer uses a NACA 63A-014 MOD airfoil; the vertical stabilizer a NACA 63A-015 MOD section. Fuji Heavy Industries supplied the rudders and elevators, optimized for steep, low-speed regional approaches.

Performance Reference Data

Nature of This Collection

This is a living collection — documents are added as new primary-source material is authenticated and processed. Purchasers receive free lifetime updates as the collection expands.

All documents in this collection are archival, static-copy editions fixed at their original publication dates. Intended for historical reference, flight simulation, museum restoration, and educational use only. Not approved for active airworthiness maintenance under FAA 14 CFR § 43.13, EASA Part-M, or equivalent international regulations. Operators of active aircraft must use current, revision-controlled publications from the Type Certificate holder or an authorized distributor.

⚠️ Regulatory Notice: Under FAA 14 CFR § 43.13 and EASA Part-M, any mechanic performing maintenance on an active aircraft must use current, manufacturer-approved revision-controlled data. This archival collection does not satisfy that requirement.
