LANDING WITH ONE JET UNIT

a. Approach the field, turning in the direction of the good

jet unit.

b. Lower the landing gear by compressed air (two complete turns

of air valve) when 3 to 4 km (2 to 2.5 miles) out on the land

ing approach. Main gear goes down in 2 to 3 sec and the nose

wheel goes down in 5 to 10 sec.

c. Lower flaps as needed, as the airplane will not go around

again on one jet unit.

d. When the landing gear has been lowered by compressed air,

the landing gear down button must be pressed when the jet

units are running, before the next take-off.

POSSIBLE FAILURES OF THE ENGINES IN STARTING AND IN FLIGHT

a. In Starting

(1) The Riedel Motor Does Not Start:

The electro-motor in the Riedel is turning the jet unit

over slowly. The voltage should read 20 v, in which case do

not use the starter switch for more than 10 sec to avoid

burning out the electro-motor.

(2) The Riedel motor sounds as if it were running, but no

rpm is indicated with the tachometer in the low-speed range.

(a) Tachometer inoperative.

(b) Starter claw is broken.

(3) The ignition does not respond immediately; press the

ignition button several times. If ignition finally takes place,

long flames will come out of the jet unit. This will also

happen if fuel has previously run into the jet unit. These

flames will blow out.

(4) The ignition is accidentally turned on when the jet unit

is stopped, and flames come out of the unit. The ignition

should be released and the Riedel motor started so that the

air flow will extinguish the flames. If the Riedel motor is

not used, a mechanic can either blow compressed air through

the front or use a fire-extinguisher at the rear.

b. In Flight.

(1) Jet unit is extinguished:

Indicated by: (a) Drop in rpm.
