Aircraft Manufacture
|
A wide
range of NDT Technologies are used to keep aircraft
flying
Many parts are periodically removed for inspection
and overhaul, in which case the technologies are
normally the same as those used in initial manufacture,
but most periodic airframe and engine inspections
are carried out with at most partial disassembly.
In this situation the procedures used during manufacturing
are not feasible due to incomplete access and other
techniques must be used. These often require special
probe and inspection jig design, normally carried
out in cooperation with the OEM’s and detailed in
the inspection manuals.
Eddy current equipment such as the ZETEC MIZ-21B
is widely used for detection of fatigue cracking,
particularly in aluminium sheet structures assembled
with fasteners. This unit also provides Conductivity
measurement, Important in checking that Aluminium
parts, such as engine compartment skins and wheels
have not suffered damage or metallurgical changes
due to overheating.
Standard Ultrasonic Flaw detectors are often
used for inspection of spars, landing gear
and other parts. It is frequently necessary
to find very small defects, and high resolution
instruments such as the Masterscan 350 are
normally specified.
Phased array equipment is beginning to be
specified in aircraft inspection procedures.
Our Sister company Atlantis provide a system
for semi-automatic inspection of Aircraft
wheels. This is normally performed when
Tyres are changed, as cracking can lead
to deflation or even explosion of wheels
