TOWING

AND TAXIING

09-00 GENERAL

1. INTRODUCTION

You can move the aircraft on the ground with:

•

pushing / pulling

•

the tow bar

•

taxiing

When towing or handling the aircraft close to obstacles (buildings, other aircraft)
a wing walker should follow the aircraft and inform about a danger of the aircraft
collision with the obstacles.

TOWING

AND TAXIING

09-10 TOWING

1. DESCRIPTION

The aircraft can be moved for a short distance by means of towing by holding
the blade roots. Handle the propeller by holding the blade root

– never blade tip.

There is also possibility of using tow bar that attaches to the nose landing gear.

CAUTION

AVOID EXCESSIVE  PRESSURE  AT THE AIRCRAFT CONTROL SURFACES
AND  THE  WING  TIPS.  THE  PERPENDICULAR  PRESSURE  ON  THE
SURFACE OF THE AIRFRAME SANDWICH SHELL THIN SKIN LAYERS CAN
PRODUCE  A  CREATION  OF  PRINTS.  THESE  PRINTS  CAN  WEAKEN  A
SANDWICH  SHELL.  DURING  THE  AIRCRAFT  TOWING  HOLD  THE
PROPELLER BLADE ROOT, NEVER THE BLADE TIP!

WHEN TOWING THE AIRCRAFT AS WELL AS DURING MANUAL HANDLING
PAY INCREASED ATTENTION NOT TO DAMAGE WINGS, TAIL SURFACES
OR OTHER PARTS OF THE AIRCRAFT.

WARNING

MAKE  SURE  THAT  THE  PINS  OF  THE  TOW  BAR  ARE  CORRECTLY
ENGAGED  IN  THE  NOSE  LEG.  IF  THE  PINS  ARE  NOT  CORRECTLY
ENGAGED,  THE  TOW  BAR  CAN  DETACH.  THE  AIRCRAFT  CAN  CAUSE
INJURY TO PERSONS.

CAUTION

WHEN TOWING THE AIRCRAFT AS WELL AS DURING MANUAL HANDLING
PAY INCREASED ATTENTION NOT TO DAMAGE WINGS, TAIL SURFACES
OR OTHER PARTS OF THE AIRCRAFT.

MAKE SURE THAT THE AIRCRAFT IS ON LEVEL GROUND. IF YOU TRY TO
MOVE THE AIRCRAFT ON GROUND THAT IS NOT LEVEL, YOU CAN LOSE
CONTROL OF THE AIRCRAFT.

THE NOSE WHEEL STEERING IS COUPLED WITH THE RUDDER CONTROL.
WHEN TOW BAR IS ATTACHED, THE NOSE WHEEL MAY NOT BE ROTATED
THROUGH FULL MOVEMENT RANGE TO PREVENT DAMAGE OF NOSE
GEAR.

1. INTRODUCTION

This chapter determines instructions needed for parking and mooring of the aircraft
at all expected weather conditions. A procedure for anchoring the aircraft must always
be realized if strong wind or long term parking of aircraft is expected. This chapter also
contains instructions that should be executed during storage of the aircraft.

PARKING / STORAGE

1. DESCRIPTION

Parking  procedure  depends  on  parking  time  (or  on  expected  weather  conditions).
If adverse weather conditions are expected (very strong wind, downpours, sand storm
etc.), the aircraft should be parked inside a hangar. When parking inside the hangar,
carry out the same operations as during a short-time parking.
When  parking  on  a  surface  without  sufficient  loading  capacity,  e.g.  asphalt  surface
at high temperatures or wet soft surface, there is a danger that wheels will sink into
the surface. Park the aircraft on a hard surface of the apron where mooring equipment
is built in. Do not park on a surface with insufficient loading capacity.
Storage  procedure  is  intended  to  protect  the  aircraft,  if  removal  from  service  is
assumed.  The  main  aim  is  to  prevent  from  corrosion  and  damage  of  aircraft  parts
exposed to weather.
Depending  on  the  time  after  which  the  aircraft  will  remain  inactive,  the  storage  is
divided on:

•

temporary storage (30 to 90 days)

•

long term storage (over 91 days).

If possible, park the aircraft in a hangar.

MOORING

1. GENERAL

The aircraft is moored when parked outside (on apron). A correct mooring is highly
important if strong wind is expected, or during long-time parking. When a strong wind
affects the aircraft (e.g. storm), the aircraft structure could be damaged. When strong
wind is expected, park the aircraft inside a hangar. If this is not possible, the aircraft
has to be moored.

2. MAINTENANCE PRACTICES

A. Mooring

The following tie-down points are provided on the aircraft:

•

On the wings

–
