Workshop maintenance and preventive maintenance,

In the table below you will find a checklist of preventive maintenance tasks:

Daily

for lamp failure

Replace lamp and film disc cut-out (if any).

for low light output

1. Clean outer surface of prism if dirty.

2. Check for misalignment or presence of moisture
in fixture.

3. Check for lamp ageing or displacement

Weekly

for obstruction in light output
channel

Clean channel and prism surface

Monthly *

for presence of moisture or
water (visual inspection on
condensation inside of
prisms)

1. Open up light assembly.

2. Clean, dry and inspect.

3. Replace O-ring and other parts found defective.

Bimonthly

torque on hold-down bolts

Refer to the table “Screws Overview” on page 43
for the tool to use, the torque to apply, and the
eventual use of “Loctite” sealing compound.

Semi-annually *

for presence of water in
base

1. Pump water from base.

2. Remove, dismantle and inspect light for water
damage.

3. Cure the cause of water ingress.

After 800 hours
of operation at
6.6 A

Replace lamps of complete
subsystems (e.g. R/W
centreline)

It is recommended to replace the lamps
systematically when 80 % of the useful life has
been reached. At  full brightness (6.6 A), it
represents 800 hours, but, in practice, life spans of
2000 to 4000 hours can be expected.

After snow
removal

for damaged light fixtures

1. Replace badly damaged fixtures.

2. Use a power broom for snow removal in the
vicinity of the light fixture, if practical.

3. Follow recommended snow removal techniques
described in FAA AC 150/5200-23 to avoid or at
least to reduce damage to light fixtures.

* More frequently during rainy seasons.
