Hello chrisnial-ga; thank you for the question. I have provided a
list of the major companies that specialize in NDT/NDI in the UK and a
few global and U.S. leaders as well.
Many of the large aircraft manufacturers perform these tests in-house,
and thus have their own hired NDT specialists. The companies I have
listed are either independent test consultants or are large providers
of the technology itself.
I also included news on events relating to NDT in the industry and a
number of useful links.
Please let me know if I can add to this response to suit your needs.

Krautkramer and Agfa
(have since been acquired by GE, but the information should be helpful)
Major Acquisition in Non-Destructive Testing (NDT) for Agfa
"The Krautkramer business consists of the production and worldwide
distribution of ultrasonic devices for the non-destructive testing
(NDT) of various materials, especially metals. Krautkramer sells
portable as well as stationary testing devices. In 1999, the
Krautkramer business, with manufacturing plants in Hürth (Cologne,
Germany) and Lewistown (Pennsylvania, USA) and offices in Germany,
USA, Brazil, UK, France, Italy, Japan as well as other countries in
the Far East, accounted for worldwide sales of roughly 100 million
Euro. Krautkramer employs over 650 people worldwide.
The global non-destructive testing market is estimated at 1 billion
Euro, in which radiographic systems represents a share of 15 % and
ultrasound systems has a good 30 %. In the segment of radiographic
systems, Agfa has a marketshare of 60 %. Through the acquisition of
Krautkramer, market leader in ultrasound systems, Agfa obtains 32 % in
this promising NDT-segment.
"Non-destructive Testing is one of Agfa's core businesses less known
to the general public. However, Agfa sells industrial radiography
systems that are used to test the safety of eighty percent of the
world's passenger aircraft, and most major pipeline projects around
the globe are tested with Agfa receptors. With this acquisition Agfa
broadens its technology base in the NDT-business adding high tech
ultrasound hard- and software technology, which is considered to be
one of the most promising and fastest moving technologies in
non-destructive testing.", said Dr. Ludo Verhoeven, vice chairman of
the Agfa-Gevaert Group."
"The Agfa-Gevaert Group headquartered in Mortsel, Belgium ranks among
the world's leading imaging companies. Agfa develops, produces and
markets analog and digital systems, primarily for the graphics
industry, medical radiology, non-destructive testing, micrographics,
motion picture film and consumer imaging and photography markets. Agfa
employs about 22,000 people in 40 countries, and has 120 agents
throughout the world. Together, they achieved a turnover of 4,731
million Euro in 1999. Product and company information can be found on
Agfa's home page on the World Wide Web at: www.agfa.com"
General Electric acquired Afgha's NDT wing - it is now under GE

Diagnostic Sonar Ltd.
"The requirement for rapidly detecting corrosion and disbonds in large
areas of lap joints in transport aircraft has prompted the development
of various new NDT methods and large-area imaging systems. QinetiQ has
developed ultrasonic array technology in collaboration with Diagnostic
Sonar Ltd and evaluated the inspection performance and the potential
speed of inspection. The crucial factors in this development were the
achievement of high speed as well as high spatial and depth resolution
to allow interrogation of sealant and adhesive layers and the
characterisation of corrosion."
"Technology transfer of the array has been a successful part of this
project. The ultrasonic array is commercially available from
Diagnostic Sonar Ltd, an NDT manufacturer in the UK, and the software
to control it is available as an upgrade of current

"Right now there is no prescriptive requirement "to assure that
persons performing maintenance or inspection of aircraft meet a
minimally acceptable vision requirement," said the Federal Aviation
Administration. Though maintenance organizations have programs to
certify vision for inspectors who perform non-destructive
inspections/testing (NDI/NDT), like dye penetrant techniques commonly
used to look for cracks in compressor hubs and blades, the agency said
the requirements for those certifications are "neither uniform nor
standard throughout the industry." Of the inspector corps, 52% are
classified as "visual" inspectors, 36% as visual and NDI/NDT, and 12%
solely as NDI/NDT."

<<The Concorde disaster has again brought safety issues to the fore.
The aviation industry relies on hundreds of product and service
suppliers such as Chris Hocking, who runs Hocking NDT from St Albans.
He makes equipment used to test aircraft for cracks.
NDT stands for non-destructive testing, used to detect tiny fissures
that can develop swiftly in parts such as landing wheels and if not
discovered can lead to catastrophe. "The massive pressure in the tyres
puts strain on the rims," says Chris. "There is huge stress applied on

"RepliSet from Struers is a replicating system for non-destructive
testing and engineering inspection. It is designed to transfer the
microstructure of a surface to replica media, and produces an exact 3D
copy of an engineering surface. The replica is subsequently analyzed
off-site under laboratory conditions.
Replicas can be taken of metallic materials and most other solid
materials like ceramics, plastics, glass and concrete. There are no
size, shape or thickness limitations. RepliSet compounds are useful
for inaccessible surfaces and irregularities on critical components
that need to be examined and measured."

<<A new method of non-destructive testing is available whose
development seems fortuitously timed to meet the increasing demand for
both structural and nonstructural inspections of high-time aircraft.
If exploited to its full capability, operators will be able to
detect the presence of a faulty wire buried deep inside a bundle,
without having to disassemble the bundle (see ASW, Oct. 19).
The approach features a 13-pound multispectral camera that
detects extremely subtle variations in the spectral signature of the
material being examined. The data is fed to a laptop computer, which
compares the reading against a "baseline" measurement to produce
images highlighting strain, corrosion, cracking and other anomalies.
"This cannot be done with any other camera we're aware of," maintained
Charlie Weinert, vice president of operations for the company that
developed this technology, Thresholds Unlimited, Inc. Briefly,

"Maintenance errors could be reduced through standardization of
procedures, record-keeping and documentation, and the voluntary
sharing of error data, according to the Commercial Aviation Safety
Strategy Team (CASST), which recently released a list containing
dozens of wide-ranging safety recommendations.
CASST's maintenance agenda also includes reductions in uncontained
engine failures through improved non-destructive testing,
rotor-integrity and damage-mitigation programs. The group, which
comprises the Air Transport Association, the Air Line Pilots

"Montreal's Tektrend International is introducing a new, optical
non-destructive testing method, called Edge-of-Light, under a license
from developers at the Canadian National Research Council's Institute
for Aerospace Research.
EOL uses a light source and a scanner to convert changes in surface
slope into light intensity variations on a personal computer display,
rapidly generating easy-to-interpret results. Scanning speeds range
from two to 20 linear centimeters per second across widths of 10
centimeters or more - relatively fast compared with other NDT

new method both as a stand-alone product and integrated with
ultrasonic and eddy current inspection systems. "

"Spectronics Corp. has developed the Maxima 3500M, a battery-
operated, high-intensity, black-light lamp for non-destructive testing
(NDT). The lamp's 35-watt bulb can deliver 60,000 microwatts per
centimeter squared at a distance of 15 inches. Spectronics says its
lamp makes small defects far more visible during fluorescent and
magnetic particle inspection than standard UV lamps. The 2.5-pound
handheld unit has an instant on/off/restrike switch, and its bulb is
prefocused at the factory for optimum performance."
