SECTION 8 - GROUND HANDLING AND SERVICING

Introduction

This section contains the procedures recommended by the manufacturer for proper ground handling and routine servicing of the aircraft. It also identifies some inspection and maintenance requirements that must be followed if the aircraft is to maintain its original performance and reliability.

It is recommended to follow a planned program of lubrication and preventive maintenance based on local climatic and operating conditions.

NOTE For detailed maintenance procedures, always consult the Aircraft Service Manual and the Engine Service Manual.

Aircraft Inspection Periods

Inspection intervals occur every 100 hours of flight and in accordance with special inspection programs that are added to regularly scheduled inspections.

REFERENCE Proper maintenance procedures are described in the Aircraft Service Manual or the Engine Service Manual.
Periodic inspection interval: 100 flight hours
Reference documents: Aircraft Service Manual, Rotax Engine Service Manual

Aircraft Alterations or Repairs

It is essential that the responsible Aviation Authority be contacted before any alteration to the aircraft to ensure that its airworthiness is not compromised.

WARNING Any unauthorized modification may invalidate the certificate of airworthiness and compromise flight safety.
REFERENCE For repairs, refer to the Aircraft Service Manual.

Ground Handling

Towing

The aircraft can be maneuvered more easily and safely by hand by pushing on the wing struts near the attachments, or by pulling the propeller blade near the hub. A tow bar can be attached to the nose gear fork.

Ground Maneuvering Methods

  1. Pushing on wing struts: Push near wing-strut attachments
  2. Pulling from propeller: Pull the blade near the hub (with engine off and magnetos OFF)
  3. Tow bar: Attach to the nose gear fork

The aircraft can be steered by rotating the rudder or, for tight turns, by pushing lightly on the tail cone to lift the nose wheel.

CAUTION Before pulling the propeller, ensure that the magnetos are OFF and that the master switch is off.

Parking and Tie-down

When parking the aircraft outdoors, orient it into the wind and engage the parking brake. If chocks or wedges are available, it is preferable to use them.

Standard Parking Procedure

  1. Orient the aircraft into the wind
  2. Engage the parking brake
  3. Position chocks/wedges at the wheels (if available)
  4. Lock the flight controls

In case of bad weather and strong wind conditions, the aircraft should be tied down. Tie-down ropes must be attached to the wing strut attachments and secured using ramp rings. The nose gear fork can be used for forward tie-down.

Tie-down Procedure

  1. Attach ropes to wing strut attachments (both sides)
  2. Secure ropes to ramp rings
  3. Use the nose gear fork for forward tie-down
  4. Lock flight controls to prevent damage from weathervaning
NOTE Flight controls must be locked to prevent possible damage to the moving surfaces caused by the weathervaning effect of the wind. For this purpose, the safety belts can be used to lock the control stick and prevent its movement.

Jacking

Given the low empty weight of the aircraft, jacking one of the main wheels can easily be performed even without the use of hydraulic jacks.

Manual Jacking Procedure

  1. Remove the aluminum panel located between the steel landing gear springs
  2. One person lifts a wing half by acting on the spar immediately before the wingtip
  3. Another person positions an adequate support under the steel spring attachment, with protective covering
CAUTION Always use adequate supports with protective covering to avoid damage to the structure. Never leave the aircraft jacked up unattended.

Leveling

Leveling the aircraft may be necessary to verify wing incidence, dihedral, or the exact position of the center of gravity.

Leveling condition: Leveling is achieved when the cabin floor and, in transverse direction, the main gear support beam are horizontal.

Road Transport

It is recommended to securely fasten all aircraft components on the trailer to avoid damage during transport.

Minimum trailer dimensions: 7 x 2.5 meters

Transport Recommendations

  1. Position the wings under the aircraft fuselage
  2. Secure the wings with specific clamps
  3. Protect secondary components (stabilizer, struts) with plastic or other protective material from accidental impacts
  4. For correct rigging and de-rigging procedures, consult the Service Manual
REFERENCE For correct rigging and de-rigging (assembly and disassembly) procedures, refer to the Service Manual.

Cleaning and Care

Painted Surfaces

To clean painted surfaces, use a mild detergent such as the shampoo normally used for automobile finishes. Use a soft cloth to dry.

Windshield and Plastic Windows

The windshield and plastic windows should never be dusted dry. Use warm soapy water and dry only with chamois leather.

WARNING NEVER use products such as gasoline, alcohol, acetone, or other solvents on plastic windows. These products can cause permanent damage.
NOTE Special glass cleaners may be used, but in any case avoid products containing solvents.

Cabin Interior

To clean the cabin interior, seats, upholstery, and carpet, foam-type detergents are generally recommended.
