GENERAL

1. INTRODUCTION

This Pilot’s Operating Handbook is designed for maximum utilization as an operating guide for the pilot. It includes material following guidelines of production aircraft required by C.A.R. 3 and FAR Part 21, Subpart J. It also contains supplemental data gathered from the kit manufacturer.

This handbook is not designed as a substitute for adequate and competent flight instruction, knowledge of current airworthiness directives, applicable federal air regulations or advisory circulars. It is not intended to be a guide for basic flight instruction or a training manual and should not be used for operational purposes unless kept in a current status.

Assurance that the airplane is in an airworthy condition is the responsibility of the owner. The pilot in command is responsible for determining that the airplane is safe for flight. The pilot is also responsible for remaining within the operating limitations as outlined by instrument markings, placards, and this handbook.

Although the arrangement of this handbook is intended to increase its in-flight capabilities, it should not be used solely as an occasional operating referance. The pilot should study the entire handbook to familiarize himself with the limitations, performance, procedures and operational handling characteristics of the airplane before flight.

The handbook has been divided into numbered sections. The limitations and emergency procedures have been placed ahead of the normal procedures, performance and other sections to provide easier access to information that may be required in flight. The “Emergency Procedures” Section has been furnished with a red tab divider to present an instant reference to the section. Provisions for expansion of the handbook have been made.

SECTION 3

EMERGENCY PROCEDURES

1. GENERAL

The recommended procedures for coping with various types of emergencies and critical situations are provided by this section.

Emergency procedures (if any) associated with optional equipment which require handbook supplements are in the optional equipment reference binder.

This emergency procedures section consists of abbreviated emergency checklist which supplies in action sequence for critical situations with little emphasis on the operation of the systems. Where amplification of specific emergencies is required, this manual will try to cover the additional information for a more complete understanding of the procedures.

These procedures are suggested as a course of action for coping with the particular condition described, but are not a substitute for sound judgment and common sense. Pilots should familiarize themselves with the procedures given in this section and be prepared to take appropriate action should an emergency arise.

Most basic emergency procedures, such as power off landings, are a normal part of pilot training. Although these emergencies are discussed here, this information is not intended to replace such training, but only to provide a source of reference and review, and to provide information on procedures which are not the same for all aircraft. It is suggested that the pilot review standard emergency procedures periodically to remain proficient in them.

2. EMERGENCY PROCEDURES CHECK LIST

(a) ENGINE FIRE DURING START

Starter………………………………...... Continue to Crank

Throttle………………………………...... Cut off/Close

Electric Fuel Pump Fuse………………………………...... Pull

Fuel Selector………………………………...... Off

Abandon aircraft if fire continues

(b) ENGINE POWER LOSS DURING TAKEOFF

If sufficient runway remains for a normal landing, land straight ahead

If sufficient runway remains:

Maintain safe airspeed

Make only shallow turns to avoid obstructions

If sufficient altitude has been gained to attempt restart:

Maintain safe speed.

Fuel selector………………………………...... …..Check ON

Electric Fuel Pump Fuse………………………………...... In/Set

Throttle………………………………...... …..Open/ 1 inch

Master Switch………………………………...... On

Starter………………………………...... Engage

If power is not regained, proceed with power off landing.

Fuel Selector………………………………...... Check ON

Electric Fuel Pump Fuse………………………………...... In/Set

Throttle………………………………...... Open

Master Switch………………………………...... On

Engine gauges………………………………...... Check for indication

of cause of power loss

If power is not restored prepare for power off landing.

Maintain 50-60 MPH glide.

(d) POWER OFF LANDING

Locate suitable field…..avoid roads because of power lines/traffic

Establish spiral pattern

1000 ft. above field at downwind position for normal landing approach.

When field can easily be reached slow to 45 MPH for shortest landing.

When committed to landing:

Ignition switch………………………………...... OFF

Master Switch………………………………...... OFF

Fuel Selector………………………………...... OFF

Seat Belt/Shoulder Harness………………………………...... Tight

(e) FIRE IN FLIGHT

Source of fire………………………………...... Locate

Electrical Fire………………………………...... Isolate Equipment

Fight fire with extinguisher if necessary.

Issue Mayday.

Land as soon as practicable.

Abandon aircraft if over unpopulated area and unable to land.

Engine Fire:

Fuel Selector………………………………...... OFF

Throttle………………………………...... Closed

Electric Fuel Pump Fuse………………………………...... OPEN

Master Switch………………………………...... OFF

Issue Mayday.

Proceed with power off landing procedure.

Abandon aircraft if over unpopulated area and unable to land.

(f) LOSS OF OIL PRESSURE

Land as soon as possible and investigate cause.

Prepare for power off landing.

(g) LOSS OF FUEL PRESSURE

Electric Fuel Pump Fuse………………………………...... IN/SET

Fuel Selector………………………………...... ON

Engine should continue to operate from gravity feed only.

Land as soon as practicable.

(h) HIGH OIL TEMPERATURE

Land at nearest airport and investigate the problem.

Prepare for power off landing.

(I) ELECTRICAL FAILURES

This aircraft is equipped with a simple 12 volt system. The battery is a dry cell unit and is mounted in the forward right section of the interior, just aft of the firewall. If a particular electrical accessory becomes inoperative in-flight, the most common reason would be the unit has become disconnected from the accessory plug-in below the instrument panel. If a total loss of electrical components fail the most likely cause would be the MASTER SWITCH has been inadvertently moved to the CLOSED position or there is a grounding situation. In either case the total loss of electrical power will shut down the engine.

Total Loss of Electrical Power……………………………Cycle MASTER SWITCH

Attempt restart of engine.

If unable to regain power, prepare for emergency landing.

(j) SPIN RECOVERY

Throttle………………………………...... Idol

Ailerons………………………………...... Neutral

Rudder………………………………...... Full opposite to direction of rotation

Control stick………………………………...... Full forward

Rudder………………………………...... Neutral whenrotation stops

Control stick………………….. As required tosmoothly regain level flight attitude

(k) ENGINE ROUGHNESS

The carburetor heat feature is built into the carburetor through a brass tube extending from the exhaust manifold attached directly into the bottom of the carburetor. If engine roughness is experienced in-flight, the most likely cause is this vent tube has become unattached to either the carburetor or exhaust manifold. Descend to a lower altitude to find warmer air and land as soon as practicable.

Another possibility is fuel contamination. After landing, check fuel filter and remove and replace as necessary.

SECTION 4

NORMAL PROCEDURES

1. GENERAL

This section describes the recommended procedures for the conduct of normal operations for the Airdrome Fokker DR-1, N8092L

Normal procedures associated with those optional systems and equipment which require handbook supplements are provided in the optional equipment binder.

These procedures are provided to present a source of reference and review and to supply information on procedures which are not the same for all aircraft. Pilots should familiarize themselves with the procedures given in this section in order to become proficient in the normal operations of the airplane.

The first portion of this section consists of a short form checklist which supplies an action sequence for normal operations with little emphasis on the operation of the system.

The remainder of the section is devoted to amplified normal procedures which provide detailed information and explanations of the procedures and how to perform them. This portion of the section is not intended for use as an in-flight reference due to lengthy explanations. The short form checklist should be used for this purpose.
