9.3.6
Analog Airspeed Indicator
A leak test should be performed on condition or as required by applicable regulations.
Normally, the instruments remain serviceable and accurate over a long period of time. If test or repair
necessary, the instrument is to be sent to the manufacturer or a qualified repair station. The instrument
should be packed in shock absorbing material, and the connection fittings should be sealed. The
Manufacturer strongly advises against service by unqualified personnel.
Manufacturer recommends checking airspeed indicators after 5 years.
9.3.7
Analog One Pointer Altimeter
Visually check altimeter for integrity and clean it.
9.3.8 Magnetic
Compass
with Deviation Table
Inspect the compass for secure mounting, damages, leaks, and filling by liquid. Air bubbles and clouding
are not allowed. Liquid must be transparent. Check for presence of deviation card and seal.
9.3.9
Flap position indicator
Inspect annually for operation. If inop - contact Flight Design USA.
9.3.10 Hobbs Hour Meter
Maintenance is “on-condition” only.
9.3.11 Radio Garmin SL30 with VOR functionality
The SL30 unit is designed to not require any regular general maintenance except as included in this
section.
VOR Checks
Even though the SL30 is designed to utilize the most state-of-the-art DSP technology and maintain a very
high accuracy and repeatability record, it still must undergo the VOR accuracy checks as required by the
applicable requirements.
The last VOR check information may be entered into the SL30 via the system mode VOR Check. See the
Garmin SL30 operator's manual for details.
Reference Oscillator (Com Only)
The reference oscillator frequency should be checked approximately every 3 to 5 years to ensure the
units transmit frequency is within allowable tolerance.
The oscillator frequency can be checked by connecting the transmitter output through an appropriate load
to a calibrated frequency counter. The transmit frequency should be within 15ppm of the selected channel
frequency. Contact the Garmin AT factory for instructions on adjusting the frequency if required.
Cleaning the Front Panel
The front bezel, keypad, and display can be cleaned with a soft cotton cloth dampened with clean water
DO NOT use any chemical cleaning agents Care should be taken to avoid scratching the surface of the
display.
9.3.12 Radio Garmin SL40 installed with antenna
The SL40 display lens is coated with a special anti-reflective coating which is very sensitive to skin oils,
waxes, and abrasive cleaners. It is very important to clean the lens using an eyeglass cleaner that is
specified as safe for anti-reflective coatings (one suitable product is Wal-Mart Lens Cleaner) and a clean,
lint-free cloth.
