3.8.3 LANDING WITH GEAR UP

NOTE

This procedure applies if the landing gear is completely retracted.

1. Approach . . . . . . . . . . . . . . . . . . . . . . . . . . . . with power at normal approach airspeeds and flap settings

2. POWER lever . . . . . . . . . . . . . . . . . . . . . . . IDLE / just before touchdown

If the time / situation allows, the following steps can help to reduce the risk of fire:

3.	ENGINE MASTER . . . . . . . . . . . . . . . . . . . .	both OFF
4.	Fuel pumps . . . . . . . . . . . . . . . . . . . . . . . . . .	check OFF
5.	FUEL SELECTOR . . . . . . . . . . . . . . . . . . . . .	both OFF
6.	ELECT. MASTER . . . . . . . . . . . . . . . . . . . . .	OFF
Touchdown:
7.	Touchdown . . . . . . . . . . . . . . . . . . . . . . . . .	contact surface with minimum
		airspeed
8.	On ground . . . . . . . . . . . . . . . . . . . . . . . . . .	maintain directional control with
		rudder as long as possible so as
		to avoid collision with obstacles

Procedures

3.8.4 LANDING WITH A DEFECTIVE TIRE ON THE MAIN LANDING GEAR

CAUTION

A defective (e.g. burst) tire is not usually easy to detect. The damage normally occurs during take-off or landing, and is hardly noticeable during fast taxiing. It is only during the rollout after landing or at lower taxiing speeds that a tendency to swerve occurs. Rapid and determined action is then required.

1.Land the airplane at the edge of the runway that is located on the side of the intact tire, so that changes in direction which must be expected during roll-out due to the braking action of the defective tire can be corrected on the runway.

2.Land with one wing low. The wing on the side of the intact tire should be held low.

3.Direction should be maintained using the rudder. This should be supported by use of the brake. It is possible that the brake must be applied strongly - if necessary to the point where the wheel locks. The wide track of the landing gear will prevent the airplane from tipping over a wide speed range. There is no pronounced tendency to tip even when skidding.

3.8.5 LANDING WITH DEFECTIVE BRAKES

Consider the greater rolling distance.

Safety harness . . . . . . . . . . . . . . . . . . . . . . . . . . . check fastened and tightened

CAUTION

If sufficient time is remaining, the risk of fire in the event of a collision can be reduced as follows after a safe touch-down:

- ENGINE MASTER . . . . . . . . . . . both OFF

- FUEL SELECTOR . . . . . . . . . . . . both OFF - ELECT. MASTER . . . . . . . . . . . . OFF

3.9 FAILURES IN THE ELECTRICAL SYSTEM

3.9.1 COMPLETE FAILURE OF THE ELECTRICAL SYSTEM

1. Circuit breakers . . . . . . . . . . . . . . . . . . . . . .

check if all OK (pressed in)

if there is still no electrical power available:

2.EMERGENCY SWITCH . . . . . . . . . . . . . . . . ON

3.Flood light, if necessary . . . . . . . . . . . . . . . . ON

4.POWER . . . . . . . . . . . . . . . . . . . . . . . . . . . . set based on lever positions

and engine noise

5.Prepare landing with flaps in the given position. Refer to 4B.5 - FAILURES IN FLAP OPERATING SYSTEM.

6.Land on the nearest suitable airfield.

WARNING

Engine stoppage may occur, depending on the failure mode.

Backup batteries are installed for the ECUs to provide electrical power solely to the ECU and their systems for at least 30 minutes.

NOTE

The landing gear uplock is no longer ensured. The landing gear may slowly extend.

The landing gear can be extended manually according to 3.8.2 - MANUAL EXTENSION OF THE LANDING GEAR.

NOTE

The backup artificial horizon and the flood light will have electrical power for at least 1.5 hours.
