General Flashcards
How is the locking feature of the fiber-type locknut obtained?
By the use of an unthreaded fiber locking insert.
How is a clevis bolt used with a fork-end cable terminal secured?
With a shear nut tightened to a snug fit, but with no strain imposed on the fork and safetied with a cotter pin.
Aircraft bolts with a cross or asterisk marked on the bolthead are
standard steel bolts.
Which statement regarding aircraft bolts is correct?
In general, bolt grip lengths should equal the material thickness.
Generally speaking, bolt grip lengths should be
equal to the thickness of the material which is fastened together.
Self-locking nuts may be used on aircraft provided that
the bolt or nut is not subject to rotation.
Unless otherwise specified, torque values for tightening aircraft nuts and bolts relate to
clean, dry threads.
Where is an AN clevis bolt used in an airplane?
Only for shear load applications.
Unless otherwise specified or required, aircraft bolts should be installed so that the bolthead is
upward, or in a forward direction.
When the specific torque value for nuts is not given, where can the recommended torque value be found?
AC 43.13-1B.
A fiber-type, self-locking nut must never be used on an aircraft if the bolt is
subject to rotation.
A bolt with a single raised dash on the head is classified as an
AN corrosion-resistant steel bolt.
A particular component is attached to the aircraft structure by the use of an aircraft bolt and a castle tension nut combination. If the cotter pin hole does not align within the recommended torque range, the acceptable practice is to
change washers and try again.
Aircraft bolts are usually manufactured with a
class 3 fit for the threads.
Which of these publications contains standards for protrusion of bolts, studs, and screws through self-locking nuts?
AC 43.13-1B.
