AFAB 115 MIDTERM Study Exam Questions
When installing straight pin fasteners such as Hi-Loks, Eddie bolts, and Jo-Bolts what do
you need ?-Answer exact hole dimensions to produce required strength of the joint
when are Taper pins used on an aircraft-Answer only to be used for joints subject to shear
loads and where absence of play is essential.
Can you shave an Eddie pin to achieve aerodynamic flushness-Answer it is never acceptable
when installing Eddie pins-Answer pin must be seated into hole using proper punch not by
pulling Eddie nut
can an Eddie pin installed by hand like a Hi-Lok-Answer yes
the Eddie nut lobes must be sufficiently deformed because-Answer that is the only way an
installation gage will pass completely over the lobe area
on installation the Eddie pin should contact the countersink at what-Answer .002
can you use to much sealant when installing Eddie-fasteners-Answer yes, excessive amounts of
sealant will interfere with installation
if an Eddie pin is out of grip this means-Answer the pin is either to short or to long
, when checking large qualities of Eddie fasteners what should be used-Answer appropriate
gages
is there an acceptable gap between Eddie pins and structure-Answer no, gaps can result in
an improper grip condition that require replacement of both pin and nut
what is fundamental for good joint performance and durability-Answer clean round holes
within tolerance and minimum burs
how ofter should you check pin protrusion-Answer always after nut installation
what minimizes cracks-Answer accurate hole drilling
What is edge distance?-Answer the distance from the center of the rivet to the nearest edge
of the metal
term used for fairing or feathering is called-Answer tooling
a void is-Answer any opening small crack or crevice on substrate
what type of scrapper can be used on an aircraft-Answer non metallic
what is a sag-Answer drooping of sealant
sources of contamination in sealing are-Answer personal, equipment, moisture condensation
(must be eliminated )
Sealants are affected by both what-Answer Temperature and relative humidity
