62-11-00 6-4 CHECK TEETER ANGLE
GENERAL, REFERENCES AND REQUIREMENTS
Task may only be performed by an organization or individual trained and entitled to carry out 'Professional
Maintenance'
SPECIAL TOOLS AND CONSUMABLE MATERIALS
31438 Digital level or similar
PRECAUTIONS AND SAFETY MEASURES
CAUTION: Be careful not to damage the blades while using the digital level. Any scratches or other damages on
the blade or the hub may cause a failure!
PROCEDURES
1. Engage the rotor brake.
Caution: Do not remove the rotor bag until rotor brake is engaged to avoid blade flapping.
2. Remove the rotor bag.
3. Move the rotor system until it touches the teeter stop. Hold the digital level and check the angle.
4. Move rotor system to the other side of the teeter stop and check angle again. Angle has to be 14° +/- 1°
5. If you use the tool which is mentioned above you have to sum up both angles for the blade which points
to the flight direction because while moving from the one teeter stop to the other one the horizontal line
will be crossed. For this case it is 5.60°+ 8,90° = 14,5°
6. Do it again for the blade which points to the end of the aircraft. This blade is above the horizontal line
and the angle is the difference between both measurements.
7. If you use a tool which can be put to zero than it will only show the angle movement and there is no need
to sum up or check the angle difference. Allowed angle is 14° +/- 1°.
