Important safety notifications
Various types of fixing hardware can be used for the fixation of the light on its base
or adapter ring (e.g. screws or studs and nuts). Moreover, bases and adapter rings
may be supplied with threaded holes according either to ISO metric or UNC
standards.
Only use fixing hardware of the same type as the one originally supplied with
the base or adapter ring!
Always tighten the fixing hardware to the recommended torque, using a
calibrated torque wrench and applying the recommended type of sealant!
Refer to the paragraph "How to mount the light assembly", page 17, for the tool to
use, the requirement for use of Loctite and the torque to apply.
It is possible to insert a 3/8"-16 UNC screw in a M10 threaded hole. However, such
a combination damages the female thread and does not ensure a correct fastening
so that the screw could become loose under repeated operation of rolling aircrafts.
Using screws of incorrect standard might lead to either damage to the thread in the
base or to an incorrect fixation of the lights.
Generally, using fixing hardware of a different type of the one originally supplied
with the bases or adapter rings, or tightening it at an incorrect torque, may lead to a
loosening of the fixing hardware, damage to the light and base, and potentially to
the separation of the light fitting or parts thereof from its base. This can lead to a
highly dangerous situation of Foreign Object Debris (FOD), with potential lethal
consequences.
