Jetstream 31

The Jetstream 31 is a product of BAE Systems. On March 28th, 1980 – the First flight of the BAe Jetstream 31 prototype took place. The Jetstream 31 offers the largest cabin in the 19-seat class of aircraft and has been proven to be both safe and economical in worldwide operation. The aircraft is flying throughout the world in 18/19 seat Commuter, 8-12 seat Corporate Shuttle, Air Ambulance and other Special Role Configurations. The aircraft is a fast, reliable turboprop airliner designed with passenger comfort in mind.

During our production of Northwestern Air Lease a multitude of the Jetstreams on board systems are reviewed. Below is an overview.

Introduction
The Jetstream 31 is a light transport aircraft powered by two Garrett TPE 331-10 turbo-propeller units. The aircraft is an all-metal low wing monoplane with a pressurized cabin, tricycle landing gear, steerable nose wheels and hydraulic brakes. Conventional mechanically operated flying controls, control the aircraft in pitch roll and yaw. At the trailing edge of the wings double-slotted flaps are attached.

Fuselage
The Flight deck has accommodation for a crew of two. A bulkhead separates crew and passenger compartments. In the left side of the fuselage, at the rear, is the crew/passenger entrance door which, when opened, is also the entrance stairs. In the right side, mid-way along the fuselage, is a hatch providing overwing emergency escape. At the rear of the passenger compartment is a baggage area, this area ends with a pressure bulkhead. The aircraft is fitted with a baggage pod, which can hold up to 435 pounds of cargo.

Wings
The wing is constructed with front, center main and rear spars, chordwise ribs and skin stiffened by stringers. The underside of the wing holds the retracted landing gear. The trailing edge flaps are double slotted and as in most traditional aircraft, the ailerons are located outboard of the flaps. Normal operation of the flaps is achieved through electrical control by a flap selector and hydraulic power from the engine driven pumps. Vertical and horizontal stabilizers hold both the single piece rudder and dual elevators. During the production our pilots will review these systems and explain the Jetstreams automatic flap DUMP position on landing.

Electrical
Electrical power is supplied by two engine-mounted starter/generators and with two batteries for essential supply during failure conditions and engine starting. Ground power may be used for starting.

Fire Protection
The fire protection system provides the means to detect and extinguish a fire in the engine nacelles. A smoke detection system is located in the rear baggage area. Aural and visual indications are provided to alert the flight crew to excessive temperature conditions. Four fire extinguisher bottles, two per engine, mounted in the landing gear bays are electrically discharged from the flight deck.

Stall protection
The left and right stall warning systems consist of a vane and stickshaker. The wing-mounted vane identifies an approach to the stall and warns the crew by activating the related stickshaker and audio warning (horn). The stickpusher is operated by hydraulic pressure, which automatically moves the elevators into an aircraft nose down position.

Fuel System
An integral tank of 192 gal (230.6 U.S. gal) is located in each wing. Normal fuel supply is left tank to left engine and right tank to right engine. The left and right supplies can be interconnected for crossfeeding.

Hydraulic Power
Normal hydraulic power is provided by a single hydraulic system. Emergency power is available. Normal pressure of 2000 p.s.i. is provided by two engine driven pumps for operation of the stick pusher, nosewheel steering, gear and flaps, and the supply pressure to the normal and emergency braking systems. A hand pump with an emergency selector at NORMAL provides system pressure when the engines are not running.

Ice and Rain Protection
The ice and rain protection system comprises:
- Wing and tail leading edge de-icing
- Engine anti-icing with continuous ignition
- Propeller anti-icing
- Windshield heating and demisting
- Windshield rain removal
- Stall vane and pitot heating
- Elevator horn anti-icing

Landing Gear
The aircraft has tricycle landing gear consisting of a twin wheeled nose gear and single wheel main gears. Retraction and extension of the gear is hydraulically powered. The nose gear is hydraulically steered and disc brakes are fitted to the main wheels.
