8. When the verification is complete, record on the aircraft worksheet the serial no and
calibration date of the equipment used, the serial no of the transponder, and hexadecimal
code confirmed correct.
Radio setup – follow Funkwerk handbook instructions (ATR500 manual Document-No.
01.1251.010.71e or ATR833 manual Document-No. 01.1402.010.71e).
Trouble shooting and Repair methods
Note: instrument panels are easily and quickly removed by taking out the M4 screws
around the outside of the panel, and detaching the loom and airline connections. When
refitting always recheck the pitot and static system for correct connections and operation!
See standard tests.
The wiring harness is disconnected by pulling the connector plugs apart. The airline
fittings are standard types where the collars are compressed into the middle and the lines
pulled out. The pitot and static supply to the ASI and fuel gauges are pulled out. The panel
can then be removed. Take care with any pneumatic fittings if removed – some contain
one way valves and must be replaced correctly orientated.
WARNING!
Once the panel is removed the engine kill switches are deactivated, and if started cannot
be stopped easily. Disconnect the battery earth for safety, and, where available, fit Safety
Plug RSD7222 (available from RSUK). Refitting is a reverse of the above. The panel
must be fully checked for equipment function (pneumatic, electrical, pressure) after
replacement!
Only repair instruments in accordance with manufacturer recommendations.
ASI gauge slow to respond: possibly a kinked pipe. Poor response could be water or other
blockage in the pressure feed at or near the nose.
Calibration. The unit cannot be user calibrated. If found to be in error more than 5%,
replace.
Altimeter. This unit may be adjusted if required to match height indicated to pressure
setting. Remove the small screw beside the adjustment knob on the panel. This will allow
the knob to be pulled out slightly which will disengage from one scale. Adjust the two
scales to suit a calibrated gauge, push back in and replace the screw. Note the
adjustment in the aircraft logbook with an authorised engineer signature!
RPM and engine gauges. Not user repairable, replace if faulty.
Transponder and radio. Neither unit is user serviceable. Return them to Funkwerk via their
aftersales program – see the Funkwerke website.
Antennas and cables may be replaced if faulty or broken.
Bearing temperature indicator. This is bonded to the rear face of the panel, so not easy to
remove. The battery can be replaced by sliding the small black cover off on the rear of the
unit. This is not mandatory flight equipment, and battery replacement is undertaken when
the indication becomes difficult to read or annually (see maintenance schedule).
